Title: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 18, 2017, 01:02:23 PM
Quick background: I want to build a shop on my 10 acre parcel that is all trees. The trees need to come down so I have room to build the shop. I figured I could sell the trees to pay for the lumber, but according to the forester I was working with, nobody wants spruce. He wanted to charge me $1500 to take the trees down and get rid of them for me. I figured that was the deal of a lifetime. So I kindly told him no thank you.
Since the trees need to come down anyhow, I decided I was going to take them down and mill them myself. I quickly found out that when I add all the features I want to any mill they are over $10,000. They are definitely very nice mills and probably worth the money. Unfortunately I do not have that kind of money just lying around.

I started sourcing parts to build a mill. This became very cumbersome and tedious. I could find all the parts I needed just in too many locations. During my parts hunting I found Linn Lumbers website. They sold basic kits to complete kits. Fully assembled or pieces. I found it was quicker easier and about the same price if I just ordered their basic kit. I also ordered their raise and lower kit along with the track rollers. And the drive clutch.

The journey is half the fun, right? Well, I believe that. I also really enjoy fabricating and working with metal. So the journey began...

After placing the order I received 4 boxes. I had them shipped to my work to try to save on shipping charges.

That was great, but when you grab the stuff at the loading dock thinking you are a big man and can handle carrying them to the parking, think again. They get heavy fast.

Here is what showed up in the boxes. A little bit overwhelming and exciting.

So after the inventory was completed it was time to start the build.

My biggest complaint I have about this kit involved none of the cuts were square. I spoke with the owner. He was going to look into it. So I spent a day truing up the faces I wanted to use for the datum's. This should make it quite a bit easier to assemble.

Since I have the mill and I am kind of particular about everything be square and true, I used the mill to drill and tap all my holes.

First step was drilling a pilot hole. I started by using my centering tool to get the hole in the center.
(https://forestryforum.com/gallery/albums/userpics/45059/20170825_164418.jpg?easyrotate_cache=1505754396)

Once that was set I locked the mill table in place. I then used a 90 degree bit to start the hole.
(https://forestryforum.com/gallery/albums/userpics/45059/20170825_164525.jpg?easyrotate_cache=1505754439)

Next step was to drill the appropriate size hole for the tap.
(https://forestryforum.com/gallery/albums/userpics/45059/20170825_164655.jpg?easyrotate_cache=1505754479)

Followed by manually tapping the hole using a tap center. I chose to manually tap the hole because I had better control of the process preventing broken taps.
(https://forestryforum.com/gallery/albums/userpics/45059/20170825_165123.jpg?easyrotate_cache=1505754536)

The final step was to clean up the first thread. I used the 90 degree bit once again and barely touched the hole just enough to remove the burr.

Picture before cleaning

Picture after cleaning

I think it may be time to get a new bit. That one's getting a little dull.

Just drilling and tapping the holes took me an entire day. There are a lot of holes on the sawframe.

So I forgot to talk about the main rails when I was drilling and tapping holes. The 2 main rails had ½" plate to be welded to the face. Then ½" holes drilled and tapped through the plates. These plates are for the band wheel pillow block bearing. I wanted to drill and tap the plates after welding to make sure they lined up perfectly.

This was a great idea. What I didn't think about until I was tapping was the heat affected zone (HAZ). When you weld you change the physical characteristics of the steel. In my case I hardened it. This made drilling and tapping a little more work. Good thing it was a 1/2x13 tap.

Remember how I said it had been a while since I had a good welding project. Here are the first welds on my build.

Post by: Crusarius on September 19, 2017, 08:18:38 AM
With the main rails all drilled and tapped I switched over to the slide rails. These required the same ½" holes for the other pillow block bearings. It also required a square hole cut in the 2.5" square piece for the adjustable blade guide. Once again, I have a mill. Why not use it? I probably went a little over the top since it took quite a bit more time to mill the hole than to just cut it. But the results are quite a bit nicer.
You can see the completed drill and tap on the heavy plate and the hole for where the adjustable blade guide will be bolted.

Here is how it looks with the slide and the adjustable guide bolted together.

These pictures are a little out of order, hopefully they will make sense towards the end.

So the picture above shows the wrong way to put a saw frame together.

When I was tacking it all together during mockup checking all the fits I must have been standing on my head. I went back and forth 100 times and still tacked it together so the guide wheel was on the wrong side of the frame. This is why you never full weld until everything is right. I cut the tacks reversed everything and this is how it is supposed to be.

One thing I did not know about pillow block bearings is the self centering ability. When I got the bearings they were twisted. I was confused so I contacted the company and asked about them on here. Several members told me that is normal and it is for centering everything. I figured I would pass on that knowledge.

This is how they looked when I got them. They did in fact self center and aligned perfectly.

So where is all your adjustment for band length and tracking?
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Ga Mtn Man on September 19, 2017, 08:56:46 AM
...and the horizontal a vertical tilt adjustments on your blade guide?  ???
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 19, 2017, 09:27:21 AM
Band length and tracking

Band length adjustment is accomplished with the main rails being 2" square and the slide part being 2.5" square. The 2.5" slides over the 2". There is a hydraulic tensioner that pushes the two pieces apart.
(https://forestryforum.com/gallery/albums/userpics/45059/hydraulic_tensioner.jpg?easyrotate_cache=1505827489)

The tracking adjustments are ½" steel blocks with 3/8 tapped holes welded to the frame. Using a 3/8" adjuster bolt.
(https://forestryforum.com/gallery/albums/userpics/45059/bandwheel_adjustment.jpg?easyrotate_cache=1505827490)

Horizontal and vertical adjustments on blade guide

I am not overly crazy about the blade guide adjustments. The instructions said to drill a ¾" hole. That gives plenty of adjustment just no fine adjust. When I get closer to putting a blade on I may end up changing the parts to have some type of fine adjustment. The only blade I have had on the sawframe is a piece of 1.25" steel banding I acquired so I did not have to worry about shredding myself with a real blade.

This shows the dummy blade and the tensioner. The hole you see in the side of the slide is for taking out the left to right movement. There are two matching holes on the other side.

Post by: Bob_T on September 19, 2017, 10:11:00 AM
Nice build.  Good idea to use a steel band as a blade while working on the mill.  I was surprised that welding on the bearing mounting plates managed to harden them.  My attempts to harden mild steel on purpose have failed and I thought it was unhardenable.

Maybe Linn Lumber will also follow along and pick up some tips for improving their kits, although I understand they are pretty good as they are.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 19, 2017, 10:20:27 AM
I have not been disappointed other than the square cut issue. overall the kit is top quality. The instructions leave a little to be desired though.

When I weld I usually weld hotter than I need to. I tend to heat treat a lot of my parts that way. pretty sure it was harder but it may have been the tap as well. That is getting kinda old.

Post by: grouch on September 19, 2017, 11:36:23 AM
Nice work! It's not over the top to use a mill to cut a nice hole. It would be over the top to smelt the iron to make the tools to cut the hole.

However, I get the feeling you are trying to disavow the excellent

The steel you are working with has to be high carbon to work harden.
It's not good for holding up to stress cracks. On you blade adjustment...
You need something like bolt with a locking nut so you can turn the bolt
maybe only 1/4 turn to track your blade. You will be surprised to see how
little adjustment it take to keep your band centered.

Post by: Crusarius on September 19, 2017, 12:05:13 PM
Kb I may be misunderstanding you but I do have a bolt on 3 of the 4 pillow blocks that does just what I think you are saying. However, I do not have that fine adjustment on the guides which may or may not be an issue.

I have had 1500 psi on the hydraulic tensioner with the dummy steel band. I set the tracking and the dummy blade has not moved since I set it.

I will get better pictures tonight when I get home. I didn't take to many detailed pictures of the sawframe assembly.

here you go KB, I think this will show it a little better. 3 of the pillow block bearings have one of these adjusters. The fourth has a piece of 1/4" keystock the bearing rests against. I am not sure why the kit was designed like that but so far it is working well.

Fixed guide / drive wheel end of the saw frame.

The guide support is bolted to the main frame. The holes on the piece of angle iron were drilled to ¾" with a 3/8" bolt tapped into the tube behind. The cam bolt is to assist with alignment. The guide wheel is fixed to the angle. You can also see the head to one of the pillow block adjuster bolts. The blurry piece of round stock is slid into my engine stand so I had a nice easy way to work on the frame without having to constantly flip it over.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2126.JPG?easyrotate_cache=1505908879)

This is the same part looking at it from the drive wheel side.

Hydraulic tensioner
You can see the hydraulic tensioner just resting on the saw frame. That is not the final location for it. You can also see the hydraulic ram pushing the tensioning sled. The holes you see in the top of the sawframe are for the engine / carriage mount. I have not started working on that yet.

Adjustable guide end of the saw frame.
It is hard to see in this picture but there is a piece of ¼" key stock that the pillow block bearing is resting against. After taking a closer look at the pictures I think the reason the keystock is there instead of an adjuster is for clearance. The adjuster would interfere with the bolt holding the adjustable arm to the saw frame.
The adjustable guide arm is bolted to the saw frame with 3/8" bolts going through ¾" holes. The arm is bolted to the main sawmill frame through the square hole I cut into the saw frame previously. At first I was confused about this feature, then I realized before this was added when the blade breaks there would be nothing to stop the wheel from taking off. In this configuration when the blade breaks it should only move about ½" max.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2133.JPG?easyrotate_cache=1505908872)

The bolts on the sliding frame are there to keep the frame straight when changing blades. There is also a single bolt on the other side to take up the rest of the slack. The guide is in a slotted hole that uses the adjuster to set the correct location. The T bolt is for locking the arm in place. Currently I am brainstorming trying to figure out how to add a little more support to that arm. The ½" block you see on the back side of the guide is for the tensioner rod to press against. It is not in the correct location in this image.

Post by: Crusarius on September 20, 2017, 08:40:49 AM
The arm is bolted on the same way as the fixed side. 3/8" bolts with ¾" holes. I am not sure how I am going to like trying to adjust these but we will see when I get to that point. Ignore the extra hole. That is there to lighten the frame. Truth is, I measured from the wrong datum line.

Do you braze? If so, you might want to braze a blob on the ends of those bolts that are used to take up slack for sliding pieces. They won't be doing a lot of sliding, but a sacrificial dab of phosphor bronze or brass on their ends would keep them from scoring or scratching the frame.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 20, 2017, 11:52:59 AM
That is a good idea. unfortunately I am not setup to braze. I actually thought about a thin piece of HDPE to take up the slop.

Could just get some nylon bolts.

Don't get a big head -- I bet you'll still have saw marks in the lumber from that thing.



BTW, you're not going to leave that hydraulic hose laying against the wheel, are you?

It's great to see the progression from a pile of parts to the heart of a bandmill. Thanks for the details!
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 22, 2017, 08:00:00 AM
Believe it or not the hose barely clears the wheel. That is not the final resting place for the tensioner. I would be afraid of a broken blade taking it out and those are not cheap. It will be mounted above the blade on the engine platform. Hopefully this weekend I get the roller base for the carriage put together and the engine mount.

Once the engine mount is done, in theory, I could cut something.

How is the eccentric turned by the bolt in this picture?
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2140.JPG?easyrotate_cache=1505908876)

I've looked back through the all the photos and can't see it. It looks like the bolt just passes through and therefore can't act on the disk, other than to clamp it in position. C'mon, out with your secret!
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 22, 2017, 09:08:58 AM
you are correct. the bolt is just a clamp. that is only intended to hold the angle in place vertically while you adjust horizontally.

Not the finest of adjustment but a nice light dead blow hammer will adjust it pretty easily.

I began working on the engine mount / top guard over the weekend. I started off trying to use a piece of 3" channel. It started out looking really good till I did some measuring inside and found that I only have 2.25" inside the channel. With a 1.25" blade that leaves me ½" per side. I started thinking about what happens if my tracking ends up shifting. That would probably turn into blade crashing into guard and ruin it. I also thought if I ever wanted to run a larger blade I will not be able to. So unfortunately I did not have any 4" channel so I had to pause on the engine mount.

Here is a rough image of how much clearance I have with the dummy blade. That is a piece of 3" channel.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2219.JPG?easyrotate_cache=1506350795)

This image shows the drive belt side of the assembly. The red material rollers are the perfect height to mock everything up.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2189.JPG?easyrotate_cache=1506350796)

This image shows the cut side of the assembly with engine in place and the 3" channel. I should be able to get some 4" channel this week and try that. Overall I like the design. I am planning on mounting blade guards directly to the ends of the engine mount on hinges to be able to flip them out of the way when changing blades.

Since I did not have the material I needed for the engine mount I moved to the carriage. My ultimate goal with the carriage is to make it as tight to the track as possible to prevent any debris buildup.
I started with a piece of 2x3x3/16. I through drilled the tube for a ½” bolt. Then I machined a groove to clear the track while leaving the rest of the material tight to the main rails.

Looking from the side the 2x2 appears flush with the top of the rail. I forgot to get a picture of this. The groove is roughly 1/8” deep. By grooving the steel instead of just cutting it open it is going to create one less spot for the bees to build a nest. It also does not change the strength.

Here is the completed wheel assemblies.

Assembly will end up square eventually. Apparently my clamping was not very good. I did give it a good push down the rails and had to chase it before it ran out of rail.
If I end up doing this again I will use cold rolled steel for the rails. The hot rolled has a good deal of mill scale on it that I sanded off. It got a lot better but still seems like more resistance than it should. Maybe after everything is complete it will smooth out some more.

Turn the 3" channel upside down and weld a flat plate on it to mount your engine.

Post by: Crusarius on September 25, 2017, 12:14:07 PM
Thought about doing that. I am trying to keep weight down as much as possible and not create any places for the bees to build nests. Plus then I would have to deal with drainage and debris buildup.

The other reason to have it legs down is it does a real nice job covering all around the blade.

I would stay away from the channel iron for a blade guard no matter how wide you make it.  Its just looking to mess up your blades.  I would look at doing wood with no exposed screws or nails to the blade.  That way, when it jumps off (and it will at least once... ;) ) the wood will act as a braking mechanism rather than a breaking mechanism that will eat the teeth.  smiley_furious

That is a very good point. Ox, did you ever have a problem like that on yours?

I was contemplating a nice thin layer of HDPE all the way around the blade to hopefully prevent sawdust and stuff from collecting up in there.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Jemclimber on September 26, 2017, 08:24:07 AM
You may also want to drill and tap your wheel covers on either side to accept a piece of HDPE to scrape your rails. Just cut the rail profile into the plastic, and mill a slot so the height can be adjusted.  Sawdust will build up on the rails and get compressed by the wheels otherwise. It's Woodmizer's solution on my LT15 to this issue. 
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 26, 2017, 08:55:16 AM
That is exactly what I am planning. but I may end up just using sheet metal. My plan for that was a cover over the wheel that has the track profile cut in it and gravity holding it against the rail but still covering the wheel.

The cover will be hinged at the far side of the wheel pocket and gravity will hold it against the rail. It will be shaped to make a cap.

Hopefully it will keep all the debris out of the wheel pocket and minimize anything getting ground into the track.

The only time teeth touched the steel inside the guards for me was when blades break, but at that point it of course doesn't matter.

I've never had a blade walk off the wheels due to misalignment or other reason.  I'm impressed with how the mill holds its adjustments.  I haven't had to change a thing.

If I had a choice of wood or steel for the blade to fly into when coming off the wheels wood is the winner.  It protects the teeth like the guys have said already.

If you like steel, maybe line the insides of the guards with wood or a hard plastic or something.  Or not.  Plenty of mills out there with steel guards! 

The way I see it, blades flying off shouldn't be happening if you carefully align your mill at the start and keep an eye on where the blade is riding on your guides and wheels.  It will warn you if you need to re-align.  Don't try to back out of a cut with the blade running.  And don't back the head up after a cut without raising it a little to clear the end of the log. 

I'm enjoying following your build thread.  You're doing a good job.

Kb I may be misunderstanding you but I do have a bolt on 3 of the 4 pillow blocks that does just what I think you are saying. However, I do not have that fine adjustment on the guides which may or may not be an issue.

I have had 1500 psi on the hydraulic tensioner with the dummy steel band. I set the tracking and the dummy blade has not moved since I set it.

I will get better pictures tonight when I get home. I didn't take to many detailed pictures of the sawframe assembly.

Post by: William1961 on September 30, 2017, 03:08:22 PM
Hello.
Now I see what the difference in belt heights could be from.
Your sheave is 18.25" in dia.
Mine is 18.75".
This maybe the reason why my belts seem lower as they are more compressed into the pulley groove due to more tension with the larger diameter.
Well my theory.
I have also seen posts where the outside edges have been machined down about 1/8 of an inch to expose more belt.
I may try this depending on who made your belt.
Thanks.

So how much space do you guys have between the back of the blade and the guard? I think I have just enough to drop a blade in there and make it very hard to get back out. I want to move it forward some. anybody have any thoughts? The gap is roughly 1 1/8" from the back of the wheel.

The blade wants to spring outward, so you are not likely to have much trouble with it dropping behind the wheel.  If anything, I'd make the gap larger so a twisted (broken or thrown) blade can't get wedged in there.

So I kept threatening to post a picture of the carriage roller side view. This show the gap under it. I milled a slot up into the 2x2 rail for clearance but that should do a good job of keeping debris off the rail. between the wheels. I will also be adding scrapers front and rear of the carriage.

I finally found the piece I decided to use for the engine mount / top blade guard. My original plan was a piece of channel. Unfortunately, my steel supplier did not have any 4" channel in the shorts pile. I did not want to buy a 20' stick of it. I did find a nice piece of 4 x 6 angle that I decided to use instead. Best part was it was already the right length.

(https://forestryforum.com/gallery/albums/userpics/45059/20170930_193637.jpg?easyrotate_cache=1506970471)

I did end up using some of the 3" channel I originally had for the engine mount to make the vertical supports for the angle I used instead of the channel.

I added some slotted holes to the engine mount for belt tensioning. I am really wondering if I should have gone to a separate tensioning system. I still need to add something to slide the engine. Right now it's as tight as I could get it by hand. It is also very difficult to keep the engine straight while tensioning.

The horizontal tubes you see will be welded to the cross bar on the carriage.

To adjust your engine just take an eye bolt and put it under one of the nuts that
holds the engine down. One by your pulley is best. Then weld a chunk of metal
on your mounting plate and drill a hole for the other end of your eye bolt. This
makes it so easy to pull your engine back.

Well since I screwed up and I thought 48 - 2 was the correct size I cut my cross pieces to 46". they should have been 44" if I took off both rails instead of only the one. By the time I realized I had already put them in so the bed is now 50" wide. With the 3/8 welded to the outside for my wheels is 50.75 to outside. so that make 50.375 center to center on my rails.

50.75" Center's on your rails is more than what I had planned.

Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit

50.75 is to the outside of the roller rails. the center  to center on the frame is 48" which actually gives me a 50" wide bed.

I dunno if it will be to narrow. I am making this up as I go :)

Part of the reason I wanted 48 wide is so I can use the trailer to go pickup steel when I need to do a steel run. getting old borrowing a trailer all the time.

So I fixed the band wheel gap. Now it is roughly ¾". Unfortunately I also found a problem with my carriage design. If I keep the current design I would only be able to have roughly a 12" tall back stop. I think with 36" capability that is going to be a little short. So I had to change my carriage design from a vertical 2x6 cross piece to a horizontal.

This image shows the band wheel gap and my original design for the carriage cross member

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2241.JPG?easyrotate_cache=1507655023)


This image shows the new layout. I decided I am going to steal a page from williams book. I think it was William. I dunno I read so many threads. I liked the idea of using a 6 gallon boat fuel tank on the back side of the carriage. So now the engine mount will continue under the cross piece and get a square frame on the back side for a fuel tank. Hopefully this will help offset some of the sawframe weight. Of course I already fixed the band wheel gap so now I need to cut it off again and make those rails continuous.

I made some progress on the raise lower setup this weekend as well. I am not sure how I am going to like this but for now this will have to work. I keep wondering about using some rollers for the up down guide but figure I will see how this slides for a while. I did also figure out very quickly I am going to want electric raise and lower. That is not an easy task to take it from bottom to top.

I am not sure if I am doing this right but I positioned the sawframe so that the guide roller is just less than halfway across the material I will be using for the backstop. Hopefully this will work otherwise I may need to shift everything.

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2249.JPG?easyrotate_cache=1507655024)

The sawframe will be offset to the fixed guide side.

Overall image of weekends progress. I have the raise lower kit bolted on top. Clamps and air to hold the rest. The bed still needs a lot of work. The tacks I have on everything are starting to get pretty sketchy as this unit gets heavier.

The bars going under the carriage cross member will be bolted on so I can shift as necessary.

Just some general comments from your last few posts.  You said you had to rotate your cross bar so that you could have taller log stops.  I'm not sure how that makes a difference.  The log stops can only be as high as your blade!  I've tried to have them higher ::)

Are you using the cross pieces on the rails for the log bunks?

You also shifted your head off to one side - I don't see the need or benefit of that.  Your guide rollers, when opened up as far as they will go, are still quite a bit less then the distance between your rails.  I think you would be better to just center the head over the rails such that it doesn't stick way out on one side.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 11, 2017, 07:50:38 AM
heh, you know, your right about the sawblade height. I guess I wasn't thinking very clearly on that. either way I think I am going to like it better flat. I dunno time will tell.

Yes, the cross pieces are the bunks. they will get a cap welded on the end to keep unwanted items out of them.

The reason I offset the head is so I can use the main rail for the backstops. I am hoping to have them pivot on a pin below the rail and use the rail to stabilize them when they are up. That will give me a full 6" of material to help keep me from bending them to badly.

I did go back and forth about centering the head. But the other nice thing about the head being off center is it gives me a place to stack wood till I get to that level when sawing. then I can move the pile and keep going.

If I need to do edging which I am sure I will need to, that will be nice to have the boards right there instead of the log loader arms that won't exist for a while :)

Not that I will need to but this also gives me the ability to make the head quite a bit wider in the future.

I think you said you were using 158" blades?  I'm using 184" 'standard' blades from WM stock.  Although they only come in on angle, IIRC 9°, but work pretty well for me on softwoods.

Only mods I would need to do is extend the frame  and move a guide. Then add a spaced for my tensioner. Be pretty simple. I think I will wait till I get some sawing hours in. I dunno if I will ever max out my mill. We will see...

So I am having a dilemma I can't seem to resolve in my head.

This is the column on my carriage. I am using 2.5" .188 wall with one side cut out of it and then welding a strap across the pieces. If I weld that, and then weld the carriage into 1 piece there will be no way to take anything apart without a grinder. Is this a problem? Should I make the carriage frame bolt together? Will I ever need to take that apart for any reason?

So since my tacks were get kinda sketchy with all the weight I was adding, I decided it was time to commit. I full welded all the top joints on the mast. I added some diagonal corner bracing to try to stiffen up the frame.

Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 16, 2017, 01:30:53 PM
I have been having a major mental block on the raise / lower setup for the last 2 weekends. This is what I had to deal with.

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2264.JPG?easyrotate_cache=1508172595)

I needed some way to support the threaded rod. I was originally going to just put a piece of 2x6 steel tube to support the end of the threaded rod and support the mast at the same time.  It is 8" to the bottom of the threaded rod. The sawframe slides need to come down to 6". This definitely made it more challenging to get the added support I desired and support the threaded rod.

I thought about just notching the support for the rod but then I just kept thinking of the potential for sawdust accumulation and not allowing me to go all the way down or just one side not going all the way down.

I wanted to add some type of triangulation to help support the weight of the sawframe assembly and engine.

My wife finally came out and said "why don't you just put a plate there?"  You know, sometimes it's the simplest things that escape you. I did have to tweak her idea just slightly and bent the plates for a little wider support pad.

I added the diagonal plate to support the mast. I had to slot the channel to slide over the brace. That allows me adequate support for the mast and a place to support the threaded rod. With the groove cut into the channel that allows the slide to go down to 6". Unfortunately I did not get a picture of this detail.

This is my new cross member. I changed it from vertical to horizontal. Of course after I did that the information received from all you guys I realized it was not necessary. But hey, I think it worked out better this way. Thank you everyone for your feedback. Ignore the carriage bolts it's all I had at the time.

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2271.JPG?easyrotate_cache=1508174561)

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2272.JPG?easyrotate_cache=1508174555)

The 2x2 connecting the sawframe to the cross member is 32" long. That gives me 10" behind the cross member for the fuel tank to sit. Hopefully the fuel tank will help to offset the weight of the sawframe. At least when it is full.

I was doing some measuring checking to see how I did on alignment.
Left to right I am off the thickness of my dummy bandsaw blade. I think the banding is 0.035"
Front to back using the 32" sawframe supports I am off 1/16".
Needless to say, I am ecstatic about this! I can't believe I managed to get it that close on my first shot.

So the overall pics look about the same as they did before. I assure you, I did do something over this past weekend. :)

So I was looking on ebay for electric motors last night. I found tarp motors with 40:1 or 50:1 reduction and 40 to 70 rpm's. I have no clue what I should be looking for. If I calculated right the 70 rpm model will move my 38" travel head from bottom to top in 2.5 minutes. The wheelchair motor I found has a freewheel function so I can get it close with the motor then fine tune with the crank.

Help. I dunno what I want. I definitely know I want something. Cranking this beast up and down is already old.

On a side not I have a lift chair just given to me. I think it has a 24 volt linear actuator in it. Thinking that may work for a toe board?

You can make that do... You can adjust your speed with sprockets and a controller.
If it goes to slow you will be wasting time. If it goes to fast then you will be
overshooting your mark. The speed of the gearmotor needs to match whatever you have
for your winch. My winch is a wormgear winch. If your ever take your gearmotor out of
gear you better have a wormgear winch or your handle will smack you to death. It's
best not to have the handle on it at all. My sprockets was 3 to 1. My winch cable pulls
on both sides. It goes up and over the top to pull up as the winch pulls down.

$21 and 60 amps for the wheelchair motor.

 (https://forestryforum.com/gallery/albums/userpics/46773/IMG_1642.JPG?easyrotate_cache=1508301541)
Probably 3 weeks to see it.
Will use it for variable speed control for raising and lowering.
My wheelchair motors will be capable of going 0 rpm to 135 rpm.
Whatever rpm works I can dial it in.
It will be able to reverse the rotation also.
And if it works then buy another for pulling the saw down the track and back.

So I was just given a lift chair. It has a 29 volt 12" linear actuator in it. Not sure how well it will work but thinking I might try to make it work for an adjustable toe board.

I will run it on 12 volt. will play with it tonight.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 23, 2017, 10:46:48 AM
Ok. so I did not play with the linear actuator yet. But I did fire up the mill and spin it using the engine. That is the last time I will do that without a proper fuel tank and blade guards. Talk about scary.

I kept getting these really nasty noises when it was spinning about half throttle. I finally decided that was enough and shut it down. Later as I started tearing it apart for paint I realized the axle on the drive side shifted. Apparently I forgot to tighten all of the set screws. Thank god I quit when I did. I only had about 1/8" before total devastation.

So I finished the carriage and the engine mount over the weekend. Everything is now torn apart. Hopefully will get to painting this week.

Working on the bed right now. Making slow progress but I think I am over that hump. The backstop design is the hardest thing to figure out right now.

Pictures will come later as I forgot to get them off the camera.

Curious about that linear actuator too. I haven't seen one with enough power to lift one end of one ton log,but I suppose they're out there. 29 volt?  Was that a typo?
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: btulloh on October 23, 2017, 08:56:02 PM
For backstops, you could weld on some 2 1/2 in square tubing vertically about 4" long and use 2" square tube inside it. Quick.  It'll get you going until you get around to making the fancy back stops. All depends on your timeline. My little manual mill has backstops done that way and they work fine. Emphasis on "manual" .

Just a thought
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 23, 2017, 09:12:18 PM
29 volt is not a typo. I don't expect the actuator to be able to straight lift a log but if the geometry is right it may be able to lift it. We will see. I will need to experiment with it.

I was thinking about doing the backstops like that for quick and easy but I don't want to have to have the stops all the way up to clear some of the offroad terrain I am expecting to be dragging this thing on. 24' trailer needs a lot of ground clearance.

I also want to connect them all together so they go up and down at the same time. It will cost quite a bit more to do that with straight up and down vs rotating.

Bed is starting to take shape. My main log bunks are 2x6x.188 spaced at 36" on center. The secondary log bunks are 2x2x.188 spaced at the same 36" on center. They are offset from the main bunks 12" which gives me a main log bunk then a 24" space to the secondary log bunk then a 12" space to the next main bunk. You can kinda see the pattern in the picture.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2286.JPG?easyrotate_cache=1508863179)

This is the connection for the rear bumper on the bed. I have the top of the bumper matching the height of the log bunks. I will be angling the bottom of the frame to mate to the rear bumper. I am doing this because I know I will be dragging it from time to time.

Space is getting tight in the shop with a 24' trailer. Ignore the tractor parked over the frame 
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2288.JPG?easyrotate_cache=1508863179)


Here is a picture looking down on the bed showing my corner brace on one of the bunks. I have 3 bunks with this brace. Hopefully it will be enough to control any racking.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2289.JPG?easyrotate_cache=1508863180)


The secondary log bunk is going to have my spring loaded log clamps. The angle will be welded to the main frame rail and bolted to the bottom of the bunk. This will give me the ability to change it out if / when I damage it. Or to change the design if I am not happy.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_2293.JPG?easyrotate_cache=1508863180)

Post by: Hilltop366 on October 24, 2017, 03:31:54 PM
I guess the best option would be to run some 12 v to the motor and see what it does, no point in spending much time thinking or fabricating if it is way too slow or weak. I will be interesting to see how it works.

So I was working on priming the mill this weekend. I kept looking at my mast detail and was never really happy with it. So instead of making forward progress I chose to cut the mast guides off and start over.

I did not take any pictures because I did not finish it but I will when I do.

Now instead of the guides being welded and permanent they will be bolted together. I started thinking this made more sense just in case I managed to get something stuck in them. Now it will be easy to field fix and gives me the ability to paint inside them hopefully minimizing any rust potential.

Post by: justallan1 on October 31, 2017, 07:52:11 AM
WOW! Great build with lots of info and pictures.
I know you are not finished, but wanted to add a couple ideas.
On my EZ Boardwalk Jr. there is a bolt on each side that runs through the carriage and frame that holds the carriage in place while moving or towing the mill down the road. I use one any time the mill isn't being used because the wind will blow the carriage around if I don't.
Something else that I like on my mill is there is a piece of steel that is attached to the carriage and wraps part way around the track to keep the carriage from getting knocked off the tracks. It doesn't touch anything or cause any drag, it's just there as a safety device for when the carriage gets bumped. When I first got the mill I accidently tested it by running the carriage down the tracks without any support under the tracks and it for darned sure is the only reason the complete carriage assembly didn't end up sitting on the ground. 100% my own fault, but it saved my mill anyhow....
Just things to think about.
Again great build.

So I talked about how I did not like my carriage support design. Here is what it was before I decided to cut it apart. The left image shows the outside and the right shows the inside. It was welded in place. As I started painting I decided I really did not like that idea. Partly because the inside of the guides was not painted and the other part was if I managed to get something jammed in there I would not be able to fix it in the field.

(https://forestryforum.com/gallery/albums/userpics/45059/old_carriage_guide.jpg?easyrotate_cache=1509452256)

I thought a bunch, went round and round. Banged my head against the wall. Then went back to simple. Simple always wins. The guide pieces are now bolt on. This gives me the ability to remove the carriage if I ever need to.

Inside

Outside

The rest of the pieces are being painted. Unfortunately with it getting colder I need to fire up the heater in the shop so I can paint some more. I have little ambition after work.

Also a "device" at blade height to prevent the blade from hitting a side support.   ;D

YES!!!! That is definitely the plan. I forgot who said that their first support is higher than the rest but I am going to copy that idea.

Still trying to figure out how to make a guard for the non fixed side. I don't know if I can. We will see.

On mine it has a drop down "foot" that is in line with the log stops and sits in front of the blade. When it's in the down position it rides maybe 1/4" below the blade and will catch on the stops before your blade gets there. You can also pull it up out of the way for when it's a nuisance. A simple design that works great.

Wait, do not fix everything bulletproof.  You need an item somewhere where you can totally destroy a blade if you have a brainfart.  laugh_at  That's the rule.  :D

KB your tab was the influence for doing that on mine. I like the idea of being able to have an idiot moment and not do major damage. I am famous for "just one more" That usually turns into more than 1 and alot of work fixing something I broke from stupidity or just plain to tired to pay attention. I have gotten better as I get older but still like to push my luck.

crap. I thought I was over my design funk. :( So I made the changes to my carriage. Went to put it back together. No go. :(

Now I am wanting to just redesign the entire thing cause that is one detail of this build I have not been happy with yet.

my 2 pieces of channel I cut to wrap the 2x6 upright is not working so good now. anybody have any other ideas? I was looking at linear bearing but no way am I going to pay that much for them.

The 2 pieces started out as 2.5x2.5 When I cut the fourth side to wrap the 2x6 they sprung like crazy. I did not think it was going to be a problem but I was definitely wrong.

Now I don't know what to do.

My frame was made from pre-welded shelving units.  The uprights are about 2" x 1".  I took some 2x4x¼ tube and sliced it to make a C to wrap around the uprights.  I lined them with some UHMW plastic (from breadboards).  Works great.  There are 8 in total.

 (https://forestryforum.com/gallery/albums/userpics/30640/20171103_a.JPG?easyrotate_cache=1509741934)

If I were to do it over, I'd make the plastic inserts one piece.  I had to use some screws to wedge them in and keep them aligned - works ok.  I've cut close to 5,000 bd-ft and the paint is still intact.

With the open front area, I added a magnetic scale:

But as it turns out, that is where I tend to push the head and it was causing it to slip a little.  So...

The "head" is made from a pair of 2x2 fairly thin walled tube that was pre-welded into 4'x8' rectangles.  I ended up cutting them down into just under 2 foot so they would fit inside the uprights with the cut off pieces becoming the uprights between the frames, making the 3-D rectangular prism.

its kinda funny. before I started this build I read just about every thread I could on sawmills. Got a design in my head. Then went to town.

Now as I am building I wish I did more reading looked at more pictures and thought about it alot more.

I am sure it will be good, but some of the things I wanted to do to make mine different from everyone else may be biting me in the butte.

Remember that even Wood-Mizer is continually making changes/improvements.  Year model and Revision# becomes important when ordering replacement parts, drive belts, etc.  Thankfully that information is kept under your WM account number and is available when you call for stuff.

New models are sometime sold as "prototypes" at a reduced price but they can be a real challenge for the buyer later on as service/parts are needed.

This weekend did not look like I did much. But I did full weld the bed. At least the parts that were ready to be welded. I started out in the shop trying to get it into a spot that would be easy to weld. Since I am so restricted on space I thought my death jack / hi lift would work the best. It was a great idea; till I realized it is only a 48" hi lift (the frame is over 50" wide). Needless to say it was still to heavy to move by hand. I added that piece of angle with a pair of c-clamps in case the jack slipped.

I scored a free torsion axle from a friend of mine. It came out of a 2 place horse trailer. I needed to cut 18" out of the center to make it the right width. Not thinking it was going to be a big deal I grabbed the sawzall and started cutting. After a whole lot of swearing and getting kicked all over the place I grabbed the grinder with a cutoff wheel. I finally got all the way through the axle to find out it was solid.
This is a picture after cutting the second cut in the band saw. You can see the torsion spring on the far end connected to the axle mount. It does have electric brakes so I can add those later if I choose to.

I made mine 39" end to end that includes the wheel pockets which are 2"x3". I also offset the mast towards the back which makes the legs stick out more in the front and takes care of the uneven load.

Trying to remember but I think I have 10" to the back of the mast then 6" mast which leaves 23" legs off the front.

The backstops rotates. It you don't want it so high then you don't
rotate it up so far. The angled bar is my toe lift with a roller on it.

did you build any adjustment into it? I may be over thinking my design a bit. I am trying to make it adjust in 2 planes so I can keep it square through the full rotation.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Kbeitz on November 11, 2017, 11:53:21 AM
It keeps the log square at all angles. I'm happy with it and the only changes
that I have made to it was to cut it off the frame and made it so i could bolt
it on. This way if something gets bent I can unbolt it and fix it. Oh... And looking
back at my pictures I cut the point off the top. It's now much easier to keep it
square. In this picture you can see at one time I had teeth on the backstops.
I found that I did not need them so off they came. You will find that the only
time you really need the squareness of the backstop in the first time you rotate
your log. After that the bottom of the log sets flat on the bed of the saw. It
also helps when your using your saw for edging.

I am so ready to give up on the fancy backstops. I made my prototype and it is nice and perpendicular straight up but as I rotate down it close to less than 90 degree angle. I wish I could get past this mental block I am having and figure this out. I know it is something very simple I just can't get to it.

The swivel end is not square to your bed frame. Put a square on the backstop and
unhook the other end off the frame and move it to your left facing the stop. Reattach
to your frame and you should be good to go.

So here we go. "The 3 week backstop story". Sponsored in part by design funk, stopping productivity since 3 weeks ago.

So I have been fighting with how I want to do the backstops on the mill. I thought about vertical stops but was not wanting to have to raise and lower each one individually. I then thought of a way to make them all powered. Unfortunately, that was going to be quite expensive. So the next reasonable option was rotating backstops. This created 2 issues. I needed to have them square to the bed through the full rotation and I want them adjustable for after I drop a big log on them and need to re square them.

I went through many iterations in my head and in AutoCAD, I just couldn't find anything I liked.
So here is version 1: This is how it started. I tried to weld tabs to the bottom of the bunk square to the bed rail. I was not very successful. Welding upside down can be quite challenging, especially with the low ground clearance under the mill. Since I did not get those tabs perfect my backstop would pull away from the rail as it rotated. End version 1.

(https://forestryforum.com/gallery/albums/userpics/45059/20171111_174954.jpg?easyrotate_cache=1510595860)

(https://forestryforum.com/gallery/albums/userpics/45059/20171111_175004.jpg?easyrotate_cache=1510595862)

Version 2: after what I considered epic failure, I did not take any pictures. Instead, I went and tilled the garden.

Version 3: I decided I need to make the backstops adjustable in 2 planes. I needed to be able to rotate it to keep it parallel to the rail and also keep it perpendicular to the bed. I decided trying to use tabs on the frame was far to challenging and not strong enough. I ended up using 2x3 tube welded to the frame for my hinge. The angle will have the pivot point for the vertical once I get to that point.

(https://forestryforum.com/gallery/albums/userpics/45059/20171112_174752.jpg?easyrotate_cache=1510595862)

This picture you can see the adjuster bolt I added to make the fine adjustments after its welded in place. It ended up working out better than I expected. Unfortunately, it requires a good deal of fabricating.
(https://forestryforum.com/gallery/albums/userpics/45059/20171112_174803.jpg?easyrotate_cache=1510595856)

The vertical piece will have a pivot pin on the top of the open tube and an adjuster screw on the bottom. That will take care of keeping it perpendicular to the bed.

(https://forestryforum.com/gallery/albums/userpics/45059/20171112_174832.jpg?easyrotate_cache=1510595856)


This is with the backstop in the vertical position you can see the angle where the vertical pivot will be along with the hinge setup.

(https://forestryforum.com/gallery/albums/userpics/45059/20171112_174903.jpg?easyrotate_cache=1510595857)


This is up inside the hinge block. It is the only way I could make it adjust in both directions and stay put after getting it set. There is a small piece of angle with a hole drilled in it for the bolt to pass through and a nut welded to that angle. The threaded rod then is rotated to slide the bolt in a slotted hole. I only slotted the one side to force it to pivot. The nut is there to lock it in place after it is set. Ignore the extra holes it took me almost all day to come up with this, and a few different attempts at hole placement.

(https://forestryforum.com/gallery/albums/userpics/45059/20171112_175002.jpg?easyrotate_cache=1510595859)

Post by: Crusarius on November 13, 2017, 01:23:55 PM
Here is my preliminary design on my log clamps. I chose to make them spring loaded. I still have quite a bit of work to do but I have the concept in my head. If only I had a print button 
The c-clamp is acting as the back stop while I was contemplating the meaning of life (aka banging my head against the wall in design funk frustration). The piece of steel on the bunk is acting as a piece of wood (it was easier to grab). There is an angled plate on the end of the bunk with the spring connected to that. I had to angle the plate so the spring would to clear the carriage as it rolls past. I am really hoping this is not going to be a problem with how tight my clearances ended up.

The vertical tube on the side is setup for a sliding piece that I am hoping to drill holes in and make a spring loaded pin for quick raise and lower.

(https://forestryforum.com/gallery/albums/userpics/45059/20171111_145113.jpg?easyrotate_cache=1510597315)

The tube against the rail is just temporary while I am proving the clamp concept. The other tube is set into the pocket that will be welded to the clamp. There will be a spike welded to the top of the sleeve as well.

(https://forestryforum.com/gallery/albums/userpics/45059/20171111_150022.jpg?easyrotate_cache=1510597316)

The proof of concept worked out very well. The only thing I am not crazy about is when clamping a light piece of wood the sleeve likes to lift up a little bit. Probably won't be a problem on a large cant but is definitely a problem on lighter boards. I will probably just drill and tap the bottom of the sleeve and install a nylon bolt to keep it tight. That should allow it to slide freely and not lift.

After playing with it for a while I realized I built it to be left handed. I am not left handed. I have since cut all the tacks and reversed everything to be on the right side. I may have been able to get used to it but trying to twist the chain to go in the slot was kinda challenging.

So your hoping that little spring is going to hold your log ?
Sometime it take a lot of force to hold a log up tight to the
backstops. On a log like this it takes a lot of push.

with low RPM's.

Remember more speed less torque. Put a speed control
on your machine and have the best of both worlds.
You can also get them real cheap off E-bay. Just watch

The amp draw is definitely a big concern. hate to kill battery going from bottom to top. Especially without a pull start on the engine.

I tested that linear transducer I scored. it runs great on 24 volts plugged into the wall with the transformer. It is really slow on 12 volt straight from a battery. But I was able to lift the corner of the trailer off the ground very easily. I think I may try it for my toe board and see what happens. I am a little concerned it is not really weather resistant so I may need to make an enclosure for it.

So your hoping that little spring is going to hold your log ?
Sometime it take a lot of force to hold a log up tight to the
backstops. On a log like this it takes a lot of push.

I will have 4 spring clamps. The spring is not really holding the load. What is actually happening is its holding the piece that slides. That piece is getting cocked and locking to the bar. It is just like a cam clamp without the cam but the spring keeps it locked to the bar.

Kinda hard to explain but that is how other mills cam clamps work. The ones that slide on the bar then they lock into place with a side load.

I used rack for that. I have to lift up to get it to slide.

The spring clamps work just fine and will easily hold any log you're able to handle on that mill. I have a Linn based mill with similar clamps & it's no sweat holding 30"+ diameter maples & oaks.

The electric motor I fear will be too weak. You'd be best using a gear reduction motor. I raise & lower my mill head manually and it's a bear, especially when the threaded rod & brass nuts get gunked up with sawdust. A motor that turns 100rpm would give you 20" of movement in 60 seconds, meaning 3 seconds per inch. While not rocket speed, it's not slow and it will exponentially increase your torque. That reduces the strain of the motor, stretching its life expectancy. Get a 300rpm motor & move an inch/sec.

I worked on the clamps and backstops a little more. I started out with this for my backstop left to right adjuster
(https://forestryforum.com/gallery/albums/userpics/45059/20171112_175002~0.jpg?easyrotate_cache=1511895945)

Then after the concept was proven I moved to this. Believe it or not one of the holes is threaded the other one is just a through hole.
(https://forestryforum.com/gallery/albums/userpics/45059/20171124_115143.jpg?easyrotate_cache=1511895946)

I also added the vertical adjustment point. I used a 3/8" through bolt for the pivot and a ½" for the fine adjustment. The long carriage bolt may be temporary till I get the right length bolt.

Here is the sliding clamp. I am using 3/8" plate with a 45 degree angle cut on the end. I am hoping this will be strong enough so when I drop a log on it, it doesn't deform to much. You can also see in the picture I started closing up the ends of the bunks to minimize critters and bees nesting.

Top view showing the spring.

I originally had it so the spring was connected to the plate covering the end of the 2x2 slide piece. When I was showing it off to a friend I found that every time I tried to hook the spring it lifted the board I was trying to clamp. I ended up making a tab to weld to the main rail so the spring cleared whatever I was clamping.

only testing i have done is playing in the shop. haven't got it cutting anything yet. I am planning to have it ready to go by springtime. today was the coldest i have ever seen in my shop it dropped to 38 degrees f.

Really want to get some painting done so I can reassemble and test everything but can't keep the heat high enough for long enough to do it. I do have some updates on work I have done. Just been to lazy to post them. Maybe I will try to do it tomorrow.

So at 25 degrees in the shop I think it may be a little to cold to be out working. I guess it is finally time for an update.

I left off on the clamps. I now have all four of them tacked together in the configuration I think I am going to like. I still need to figure out the vertical sliding piece. Good thing is I have a crazy idea in my head for that.

Now to revisit the backstops. I have all of them made and welded to the bed.
(https://forestryforum.com/gallery/albums/userpics/45059/20171126_174213~0.jpg?easyrotate_cache=1515184982)

The vertical piece is 2x2x.188 wall the large square is 2x6x.188 wall and the small square is 2x3x.188 wall. The bolt on the upright is the pivot for adjusting squareness to the bed. Ignore the extra washers I couldn't find the right length bolt. It has been fixed since these pics were taken.

The carriage bolt adjusts right to left rotation to align parallel to the bed. The bolt on the upright is the pivot to allow squaring to the bed. With these 2 adjustments I should be able to dial each of these backstops in to be pretty close. And be able to fix it after I smash them with a big log.
(https://forestryforum.com/gallery/albums/userpics/45059/20171126_174231.jpg?easyrotate_cache=1515185085)

The 2x3 is welded to the bottom of the 2x6 bunks. Each of these stops will rotate together for raising and lowering from one end of the mill. That is the reason I had to make them two way adjustable.
(https://forestryforum.com/gallery/albums/userpics/45059/20171126_174242.jpg?easyrotate_cache=1515185152)

(https://forestryforum.com/gallery/albums/userpics/45059/20171126_174326.jpg?easyrotate_cache=1515185153)

Looking up inside the backstop. The 1/2" bolt is to adjust the angle of the upright. I know this is going to be quite challenging squaring all four of them to each other. But once done hopefully I won't have to do it again for a while

Last time I put the trailer in the shop I put it in tail first. Up until then everything was being built and figured from the other direction. I finally decided it was time to reverse the trailer since I was sick of welding stuff together backwards.

Don't forget to ooh and ahh over the awesome set of pallet forks I made just for this project :) they have definitely been more useful than I thought they would be. (this is sarcasm I am not usually this vane just in one of those moods. Thank you please drive through)

The rails on the trailer are 24' long. I do not remember if the axle was connected in this picture or not. I don't think it was because it looks to far back. Could be an optical delusion?

Triangulation on the frame rail to resist twisting. I did a total of three locations just like that. Sure made a big difference when jumping on 1 corner of the frame and when trying to flip it over to weld everything.
(https://forestryforum.com/gallery/albums/userpics/45059/20171203_164630.jpg?easyrotate_cache=1515184623)

Of course now the bed is to heavy for me to move with my tractor :( Going to be interesting do all the finish welding. I may get some good practice welding upside down. I don't want to get good at that. Owwy.

Now that I have the trailer in tongue first I decided it was a good time to make the storage box. This box will most likely be used for blades and other random items. The box is roughly 48" square. Currently I am planning for an aluminum bottom but I am starting to reconsider. I think if I put a piece of plywood in there it will be much nicer to the blades. That way sharp blades can be teeth down and dull ones teeth up. Make sorting at the end of the day a little easier.

(https://forestryforum.com/gallery/albums/userpics/45059/20171221_180241.jpg?easyrotate_cache=1515185656)

I boxed in the opening with angle iron along the bottom. The cross piece is a piece of 3" channel I had leftover from another job. The square piece is a piece of 2 1/2"x.188 wall square that the 2" tongue will slide into and get pinned in place. The front piece of the trailer is bolted on to give me access to all the wires that will be run through the rails. The rear bumper is also bolt on.

It is starting to get pretty cramped in the shop now. But I can still mostly walk around it. I have found if you throw a piece of plywood on the trailer that you have lots more space. Of course this means that you have to constantly move it out of the way. I just can't win :) The backstops are tacked on and in the upright position.

So this is what the pulley looks like on the wheelchair motor I have for my raise and lower setup.

The left is the drive gear for my threaded rod and the right is the pulley that was on the wheelchair motor.

The ID of that hole just happens to be 3/4" on both of them. I am trying to see if I can find a gear with that whatever you call it shape on it. or wondering if I should tune up my machining skills and try to machine that shape on the bottom of my gear?

Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: DbltreeBelgians on January 06, 2018, 05:40:45 PM
Looks similar to a "Lovejoy" coupling. If it would match up to one you could possibly turn down a coupling halve and get a sprocket from some place like TSC and weld it to said coupling and install with correct insert. Just a thought if I'm reading this right.

You also could take both parts to a machine shop and they could mill
the slots into your gear to mach what you have. What I would do is buy
another sprocket that takes the tapered hub. Then you wont need any
keyway or anything. The tapered hub just squeezes down on the shaft real
tight.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on January 06, 2018, 10:10:04 PM
I am thinking I may end up just putting it in the mill and trying to match the slots. unfortunately I think trying to get it off the pulley then centered on a sprocket is not going to be very easy.

The sleeve part on the sprocket mimics the coupling perfectly.

so I rigged up my wheelchair motor to just get an idea on speed. I went 45" and it took 108 seconds. That is .416" per second. unloaded. I guess I need to get some more sprockets and try it loaded. I don't know if it will make much of a difference with the gear box on the motor.

I counted the teeth on my sprockets. they are 12 with #40 roller chain. I am wondering if I can get to the sweet 1/2" per second mark by going to a 9 or 10 tooth sprocket. Looking at ordering from amazon since everywhere else is about $30 for 1 sprocket.

So I needed to get the mill out of my shop so I could get my broken snowmobile in. I didn't take any pictures but I put the tongue trailer jack on the front of the mill. I was able to roll it out of the garage and into the driveway far enough out of the way to work around it getting the sled in the garage. My 2 year old was helping push the trailer. I cannot believe how easy it moved. I am very happy.

Why is it when you are working on one big project all sorts of other smaller projects keep jumping in front of the big one? Looks like I need to replace the entire bulkhead on my sled :(

So I left off contemplating the meaning of backstops. I have an idea I have not tried yet. But while I was at a loss there I chose to continue on the raise and lower setup.

I started with a 12 volt wheelchair motor I got from ebay. The wheelchair motor had a quick disconnect for disengaging the drive and also a brake. Since I am using Acme threaded rod for raise and lower I felt the brake was unnecessary, so I removed it. The motor spun easier after removing the brake.

Here is a picture of my ghetto mockup to make sure the motor had enough power to do what I wanted it to do.

I still have the stock pulley on there and you can see the release lever.  The rest of the stack of parts was what I could find to make it work for mockup. It's not pretty but it worked.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on March 12, 2018, 11:40:54 AM
After testing to make sure it would work I moved on to permanent mounting. The gearbox had those 4 bolts very convenient for mounting a plate. The slotted holes are for tensioning the chain.
 
(https://forestryforum.com/gallery/albums/userpics/45059/20180127_132742.jpg?easyrotate_cache=1520868635)
 
 
The motor came with a v-belt pulley on it. Since I am using #40 chain I needed to adapt to chain instead of the pulley. The challenge here was keeping the quick disconnect feature in case I needed to raise and lower manually because of battery issues or whatever. The pulley had a coupler on it similar to a lovejoy. The sprocket that was to replace the pulley needed some work.
 
(https://forestryforum.com/gallery/albums/userpics/45059/20180106_143817.jpg?easyrotate_cache=1515267961)
 
I tried many different ideas on trying to adapt to the sprocket. In the end I finally just put the sprocket into the mill and machined the mating coupler into the thick shoulder of the sprocket.
(https://forestryforum.com/gallery/albums/userpics/45059/20180127_132754.jpg?easyrotate_cache=1520868635)
 
The funny threaded rod was leftover from my mockup. I think I replaced it with the correct nut. I will have to check next time I am in the shop.
 
During mockup testing the carriage moved about .416" per second. I have not checked how fast it moves since it was reassembled.
 
I think I need to add a chain tensioner or a guide to keep the chain from rattling around. It is spanning a very long distance. For now this works.

Next item on the list was cant clamps. While the backstops are still under construction I knew what I wanted for cant clamps and moved on to those.

This picture shows the fixed guide side clamp. The clamp was originally square. Since I made everything so tight I realized that the flange on the guide roller would not clear the square end. I ended up machining a 30 degree angle on the back side. That is a piece of 5/4 composite decking.

The spring loaded side I left square. Hopefully this is not going to be a problem. I machined the clamp to match the height of the other side. Right now the way everything is setup it looks like my last cut will be 7/8 to 1" thick.

After test running the mill without guards I decided I would never run it again without them. So here is the start of making the guards.
 
(https://forestryforum.com/gallery/albums/userpics/45059/20180217_175132.jpg?easyrotate_cache=1520868639)
 
I had a couple sheets of 16 gauge stainless laying around that I have been moving for years. I finally decided to put them to good use.  I did not want to have to remove the guards to replace the blade so I setup a hinge from the engine mount. Still undecided if I like it or not. Time will tell.
 
Here is the start to the drive side. Long time ago a built a plate roller with the plans of building a ditching bucket for my friends excavator. The plate roller worked great to add the perfect curve to the stainless plates. It also smoothed out the dents from all the abuse they had seen.

Idle side
 
(https://forestryforum.com/gallery/albums/userpics/45059/20180217_175200.jpg?easyrotate_cache=1520868640)
 
The cover is hinged from the engine mount and has a single bolt into the sawframe. Time will tell if I like this or not. It is a pain changing the blade since I can't quite open the cover far enough to stay open. I may end up adding a link arm to hold it while changing blades. This picture was taken as I was getting ready to setup for my first cuts. The weather was not cooperating with me so I decided to try the test cuts in the shop. The drive side was temporary just to cut down on the dust flying everywhere.

The mill is not complete but I was able to make my first few cuts. Now I have a better understanding of what I need and want.
I found this perfect little test log in the firewood rack. I learned real quick why everyone hates short logs. I tried many things with my clamps to hold it but in the end I ended up having to screw it to a 2x6 and clamp it to the bed.
I do not have a youtube channel setup yet so the videos may take some time to upload but you can at least take a look at the pics.

Still need a little tweaking on the alignment of the blade but for my first cuts I am extremely happy.

In this picture you can see my 2x6 I finally used to keep the test subject under control. The last 2 cuts I made produced 1/4" thick slabs and a pig pile of sawdust I need to clean up.

during my testing I noticed that my clutch engage just off idle. I don't like this because when I have the engine at high idle the clutch i partially engaged. does anyone know how to adjust it? It is a Noram double V-groove pulley. I am hoping its as simple as a small adjustment and not have to change out springs and weights.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Ljohnsaw on March 12, 2018, 03:11:34 PM
Attach a spring to the left of the hinge point on your engine mount and the other end down on the cover.  When closed, the spring holds it closed.  When you open it, the spring travels over center of the hinge point and will hold it open.  Hope that makes sense.

Great build especially the awesome trailer system

Just have one question. 

Why do you have the pulleys inside the frame and not outside to give you maximum width. Is this due to the blades provided with the kit or is this due to design. I was looking at using one of these kits for my build in the future but would like to have it so anything that fits between the engine frame i can cut. 



Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on March 12, 2018, 04:46:06 PM
you mean the carriage wheels? They are wider than my guide roller locations. I mounted the 3/8" plate on the outside of the main rail. the wheels are slightly off center so my carriage wheel is about 1/2" offset to the outside of the frame. I wanted the wheels to be in double shear which is why I made the carriage the way I did. I was also worried about the carriage being to wide and interfering with the stabilizer jacks.



Ok. I reread your post and now I am thinking you meant bandwheels. The reason they ended up where they are is the length of the band. I wanted a standard length and that is what the kit I purchased was setup for. 

I screwed up making the trailer and accidentally ended up 2" wider than I was planning. So far I am happy I made that mistake.

I am still toying with the idea of making the mill dual width capable. Currently I have 31" between the guides. if I go to a 176" blade I will have roughly 41". I am pretty sure the 176 blade is a decent amount more cost than the 158. I don't really need the wider cut right now but If I choose in the future it is very easy to extend the sawframe and use the longer band.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: waynorthmountie on March 12, 2018, 04:50:08 PM
That is exactly what I meant by the distance between the bandmill wheels.

The idea of a dual width mill is something I had not thought of before.

Would be the best of both worlds. Cheap blades for most of your cutting and when you need to stuff a big one through you just move the Free wheel farther out.

Also the extra room on the bunks would make handling medium size logs easier and allow for more hydraulics down the road. 
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Kbeitz on March 12, 2018, 05:05:07 PM
I made my mill so it would take anything between a 145" to a 170" band.

Post by: starmac on March 12, 2018, 05:10:43 PM
One member reconfigured his woodmizer to be able to change band lengths, I have not seen anything on it since he dit it, Kind of makes me wonder how well it worked for him.

I would think it would be fairly easy to do on a 2 or 4 post mill, especially if designed to in the original build.

So I checked the speed on the raise lower last night. 0.3" per second. Was getting a little slow towards the top. Not sure if it was binding or running out of power. Need to take a closer look at it.

It was pretty easy to get it to a set height.

I definitely need longer control cables so I can move that to the side and not have to stretch over the blade. 

Yea, about the shop... good news is after sitting for a week the sawdust has dried out enough I may be able to sweep it now.

Hopefully I can get the backstops finished then get a permanent fuel tank mount and see about tweaking the blade the little bit I need to then try a full size log. I still have 2' of snow so going out and getting a log is not very easy.

Since I have not had much time to dedicate to the mill I have been working on small trivial stuff that needs to get done.
Fuel tank holder. I found a nice 5 gallon briggs and Stratton gas can that I am going to use for my fuel tank. I felt this was the best way to go so I can just swap out tanks and not have to try to fill it on the mill.
 
Here is my home made brake bending the angle iron for the tank rack.

Battery tray. I had this window mesh left from and old police car. It has been taking up space and I was sick of tripping over it. So it became my battery tray.

Then I placed it in the same homemade press brake and formed all the sides. This took a little work since the shelf is wider than the arms on the press. Little creativity and I was able to get it all done.

My adjustable guide was not parallel to the bed. I recently found out the way you are supposed to fix that is to put a jack on it and bend it. I was not to fond of that idea. Mostly because I think it would be pretty much impossible to get it perfect through the full range of motion.
 
So I added this support bar with height adjuster. I have been wanting to add some type of support to help stiffen the arm at full extension and this worked very well for dual purpose.

Throttle lever. The original setup had the engine controls on the engine. That made it so I had to constantly stretch across the mill on front of the moving blade. I decided to relocate everything to the operator side of the carriage. I forgot to take pictures of the entire setup but it still needs some major cleanup so that will come later.
 
Here is the new throttle lever.

 Crusarius,
   I have read your build thread a few times, and appreciate the time to document your build.  I'm in the process of a build myself, with several aspects mimicking yours.  My question is, after some time to use your mill are you happy with the backstop design?  I know you went through several design changes before you settled on your final design.  I'm in the process now of fabricating the backstop and thought I would ask what your after thoughts were.

I have been neglecting my build thread for a while. I been meaning to update this but haven't really had time. I do not have pictures of what I finally decided on for backstops. here is kind of a cheezy description.

I took a piece of 1" round stock and lathed a 1/2" nipple on the end of it then drilled and tapped the other end for a 3/8x16 bolt. Then I drilled a 1/2" hole in the main rail. and two 3/8" holes in the bottom of the bunks. using a piece of 2x3x1/4 angle I machined 2 slotted holes in the 3" flat of the angle and one slot in the 2" leg. this gave me the ability to adjust left right and up and down. Then I connected all 4 together with 1" square tube and use a trailer jack on the end of the bed to raise and lower all 4 of them at the same time.

When I get home tonight I will see about getting some pictures and getting this thread updated. I did not realize how far behind I was till I was just rereading the last few pages.

 Looking forward to seeing your pics.  I'm wrestling with how robust the hinge for the backstop should be.  

My guards are 1/8 sheet metal on a 1 1/2"x1/4" thick support.  The support welds to a 1 1/2" square tube that slides in the tube that supports the pillow bearing with a bolt to keep it in place.  The face of the guard is 1/16" sheet metal that is hinged on top with a hasp on bottom.  This gives me easy access if I need to change blades, and can be further disassembled if messing with something like tracking.  I also thought the 1/16" face might allow me to layer with plywood one day if I'm inclined.

That looks nice. you have anything holding that lid open when your changing blades? a sudden gust of wind will give you one nasty headache, if your lucky it will just be a headache.

Well not the best images but hopefully it will work to show you what I ended up with.

This is the full backstop. the bar at the base connects all 4 together so they can be raised and lowered from the working end of the bed. I used a trailer jack to raise and lower them. Works very well.

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_8681r.jpg?easyrotate_cache=1536282567)
 

This is a closeup of the bottom of the bunk where the backstop is mounted. the bolt holes are all slotted the ones on the bunk are slotted front to back to allow twisting the stop and the one on the round piece is slotted up and down to set the angle.

(https://forestryforum.com/gallery/albums/userpics/45059/IMG_8684r.jpg?easyrotate_cache=1536282718)
 


Ignore the poor picture this is the front backstop. You can see the trailer jack in the background with the push rod connected to the backstop. The bar along the bottom (1x1x.120) is the connecting rod between all 4 backstops.
(https://forestryforum.com/gallery/albums/userpics/45059/IMG_8686r.jpg?easyrotate_cache=1536282792)


Not the most elegant but so far they are working. Since I need to tear it all down and paint it I have not taken the time to try to square the backstops and make them perfect. It will not be easy trying to square them all the way through the rotation but I am sure I have enough adjustment to get it when I feel like taking the time to do it.

Post by: Ljohnsaw on September 06, 2018, 11:38:45 PM
I would worry that this won't be strong enough. 

My log stops are 2x2x¼ that slide vertically in a 2½x2½x¼ x 12" tube welded to the moveable log bunks.  I have not bent the 2x2 yet but I have rolled logs into them pretty hard - hard enough to make the mill tip a little.  Also, when you flip your cant, you will want to roll it into the log stops so it doesn't roll off the mill.  That will be a lot of force on them.  Yes, it is a pain to raise and lower my individual log stops but I've settled to only use 2 on a log.
(https://forestryforum.com/gallery/albums/userpics/30640/First_Cedar_2_20150930.jpg?easyrotate_cache=1443673741)
 

Another concern (others might chime in) is where knots or bumps on the log might interfere with raising and lower them if they move in an arc.

Brink5821,welcome to the forum.
Good for you,looks like a mill. ;D
What's the plan for the lumber?
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 07, 2018, 07:22:36 AM
ljohnson, are you worried about the backstops not being strong enough or the 1" square. So far both are holding up very well. The backstop is mounted at the bottom of the bunks and up tight against the rail. that gives me almost 6" of support above the rotating mount. 

as for the interference, you are absolutely correct. I have to pay attention to that when I clamp. I typically put the stops all the way up set the log then lower the stops to where I want them. lowering seems to work ok pushing through knots.

So far my biggest issue I have is when I load a log on the bed that has sweep to it and I clamp it tight the end of the log likes to get to close to my carriage and not allow me to get through. This has come to bite me a few times. I need to put a full length stop to prevent that from happening.

Cfarm, yes its a mill :D right now plans for lumber are all over the board (no pun intended) contemplating selling some of the walnut to pay for some bills that keep showing up. But every time I think about it I can never figure out what I should charge and my wife wants all of them.

Thanks everyone. it is a never ending work in progress. it really needs paint but I keep changing stuff. really need to get paint on it before winter so I can move it outside and have some room in my shop to work again.

Thanks for the pics!  I will have some time tomorrow to work on my backstop design.  You final design seems Simple yet effective.  Thanks for the safety comment on the hinged blade guard.  A clip of some sort could prevent a mess.  

CFarm, not sure what the plan is for the wood yet.  I have been teaching myself to weld and my projects keep getting more involved.  I have some woods and tress, so why not build a mill.  Don't know much about milling yet, but I stayed in a Holiday Inn Express once or twice so why not.  I was thrilled when the first run cut smooth as butter.  Maybe my plan should be to hopefully sell some slabs so I can buy a mini split for the garage.  Welding and grinding in 90+dog heat has not been fun.

Crusarius,
   Thanks for the offer! I'm hoping to have a good day in the shop tomorrow, and if I like how my backstop design works out I'll post a pic.  I live in Northern Virginia.  My mill is similar to yours in lots of ways, and different in others.  I guess I could start a build thread.  I cut my first log in the garage, and like you, got sawdust everywhere.  I heeded the advice of many and completed my guards before I put power to the blade.  It was exciting when the acme thread with handle lifted the head unit, even more exciting when the tarp motor took over the hand cranking.  The real test will be a big log, but a lot of work before then, not to mention an axel and wheels so I can move it out of the garage.

Post by: Crusarius on September 09, 2018, 10:43:01 AM
if it wasn't for the cost one of my other ideas was a vertical stop. make cups on inside of frame and use a main driveshaft from front of mill all the way to the last backstop. then put gears on the driveshaft and a rack on the verticals. That way I could crank all of them up from the end of the mill. it would make it very easy to align that way. But the cost was a little to much. and I felt the 1:1 drive would have been to hard to raise and lower. Plus then I would need some type of a lock to keep them up.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Brink5821 on September 09, 2018, 11:20:36 PM
Your crank and driveshaft gave me an idea.  I have about a foot of acme thread left. Maybe I can use it for the backstop lift mechanism.  Then I can use the same handle l have for the manual crank on the lift.  My backstops turned out OK.  I need another piece of 2 1/2 x 2 1/2 x1/4 to finish up.  The hinge is some 1 1/2x 1 1/2 square bar I had left over from another project.  One corner is rounded so it pivots and the others are left square so the hinge holds the bar in the horizontal when down.  When in the up position the side rails provide support.  In an effort to keep everything square to each other I welded all for hinges at the same time clamped to a piece of 2x2.  I also ran a solid piece of 1/2"round bar through all hinges at the same time while welding.  It seemed to work out pretty well.  For the hinge pin I am using a grade 8 bolt.  Next weekend I will hopefully get the backstop completed and am picking up a generator trailer axel that I think I can make work.

Post by: Crusarius on September 10, 2018, 07:31:24 AM
That came out really nice. I chose not to use solid bar stock in the hopes I could keep it lighter. I think that extra 2.5 square you added is going to be unnecessary. Once you get the backstops to a height you like I bet you never adjust them again. It will just be one more bolt to check for looseness.

Speaking of that I have just over 3 hours on my engine since I installed the hour meter. I started noticing bolts loosening up yesterday when I was cutting stickers. I guess now is a good time to check everything.

Chinese arbor presses break the casting ALL THE TIME.  I swear we tossed them monthly at S&W.  Hunt around, collect 3 then build your mechanized vertical backstop out of the gear and press anvil.  the gear rack cuts are already in it, just put it in a box.

I did think about some type of linkage but decided to go the easy route with the rotating stops.

Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 10, 2018, 11:02:33 AM
after milling this weekend I am wondering if the crank at the head of the mill to raise the backstops was good idea or not. I would walk over and unhook my clamps, then I would have to walk back to the front of the mill to raise or lower the stops then go back to the clamps and tighten them up again.

The crank at the head is nice when adjusting height during milling but not during moving or loading the log. I may have to rethink that. maybe move the crank to the center of the mill and make it so I can crank it from either side of the mill. 
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Ljohnsaw on September 10, 2018, 12:18:44 PM
How much milling/how many logs have you done so far?  I did a few things that I thought were great ideas at the time when I was building.  Mostly overthinking.  ::) Having a manual mill, I try not to move the log too much and try to handle the slabs and boards as little as possible.

I load the log with the backstops fully up (so I don't roll it off the back side ;)).  I level the pith and clamp.  I cut down removing slabs of reasonable weight.  I chainsaw the junk to ~4' and toss on my SkyTrak forks.

If I remove boards that need to be edged, I try to leave them on the bunks so I don't have to lift them up.  A set of side bunks would be handy (like a log holding area).  Much easier to slide then lift.

With log stops fully raised, I rotate 180° (if big, with SkyTrak).  No need to clamp and log stops are lowered to about 1".  Remove slabs and boards as above.

Now rotate 90° with the log stops fully raised - level pith and clamp.  Cut again down to target.

With log stops fully raised again, rotate 180°.  No clamping again (usually).  Might clamp some of the boards that need edging.  Much easier to clamp to a cant then just the backstops.  It also gives you a reference to measure the full length of the boards to be edged.

So, you only need to clamp about 1/2 the time.  Since I have limited space by the mill to "store" the junk/slabs, handling them once (cut and stack on forks) saves me a ton of time and not tripping over the mess is a bonus.

What I found is if you have 1 helper that gets in the groove, you will more than double your daily production and you will be less tired at the end of the day.

This is all stuff I learned from MM and others here.  It just took a while before I was following all their advice! ;D

Post by: Crusarius on September 10, 2018, 12:39:30 PM
I have been reading a lot of what you talked about. Until I actually started milling it did not make sense to me. Now it is the AHA moment :) I am starting to understand everything.

I may be up to 20 logs I milled. Sunday I milled 10, 42" long roughly 10" diameter logs into stickers. That is when I was rethinking my backstop crank location.

I am still trying to find a flow path that works for me. I thought I had one I liked but the tractor forks can't hold slabs and lumber reasonably at the same time. I run out of room.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Ljohnsaw on September 10, 2018, 12:49:19 PM
I cheat a little on the lumber storage.  I have a 10' set of rollers and a mill bed right now that is 40'+. So I roll the (smaller) lumber to the end of the mill.  When I'm done with a log, I have a pile of lumber (already cleaned of sawdust) at one end, the target timber at the other and a stack of waste on the forks.  The last thing I do on the mill is raise the log stops all the way up.  I dump the scrap in the burn pile, pick up the timber and then the lumber and take it to storage/drying area.  Then I usually put the tongs on the forks and grab the next log on the way back.

It only took me 3 years and 50 logs to figure it out. :D

I am still trying to just get a large enough area to setup the mill and still have access to both sides for log loading and unloading. Living in the woods on a hill is really challenging.
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Ljohnsaw on September 10, 2018, 04:09:48 PM
You don't have to have access to both sides.  I'm working from one side and the other is where the sawdust goes.  Only walk over there to adjust the log stop and occasionally to turn a cant.  I normally work from the clamp side to turn cants.

However, it would be nice to put a rack over there to stack the lumber as I go.  Only problem is it would be covered in sawdust :-\

From the property line on the left to the closest side of the house is a 40' elevation gain. My mill gets set up on the property line directly below the house. a 24' long trailer is not easy to maneuver in that area. Especially place in in an area you can use the tractor to load logs.

Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on November 14, 2018, 11:19:01 AM
from the engine? no. The only issue I have is the 2 posts design has a tendency to walk instead of roll. walking is when one side moves then the other moves. This may only happy when I get sawdust buildup on the rails. last time I was cutting I took my scrapers off to see if I needed them. Yup. I need them :)

One of the modifications I have been thinking of doing is moving the sawframe closer to the mast. I doubt that will do anything for the walking problem but may make it go up and down easier.

I built my mill using Linn Lumber plans. There is a lot of weight hanging out and it can be a challenge to raise the carriage. I added a set of rollers to the slides which did help a lot. I might consider a power unit later but for now this works. I also designed a different blade guide roller mount. I'm not a big fan of drilling large oversized holes to make adjustments but that's just me. I could post some pics if your interested in seeing my changes.

I agree with the large holes but understand why they did that. I have a mill, slotting holes is easy. not many ppl have that capability.

Check out this old guys build. Pay attention to his backstops and how he swings them up from the otherside. Only improvement i could think of is for them to swing the other way do a sawhead bumper would push them out of the way.

That mill of Esko's is pretty neat.  Watch the companion video for more details.  I like his blade guide bar.  He turned the square stock 45° so it will always stay true - very clever.  His head lift is simple, fast and easy, too.  I wish I saw this before my build.  Interesting theory on the linear guides for the head but seems to work for him!

So I have not updated this thread for quite some time. I just finished rereading the entire thread and realized its pretty well up to date. I am currently working on painting it so I can get it out of my garage and be able to have a little more work space.

The trailer is 90% complete. probably making a big mistake painting it cause I still need to add toe boards and finish the storage box on the front. I don't think either of those are going to be effected to much with the paint. The box will probably be built then screwed into place. I have a kool idea in my head for the toe boards but that probably will not get done till next spring.

Here is what I finally ended up with for the log clamps. I have about 10 hours on the engine and at least 8 hours have been with the latest clamp design design. I am really liking them they are working great. My only problem was the point on the sleeve was contacting before the point on the arm. So before painting them I moved the point a little to hopefully fix that problem. These clamps have held some pretty big stubborn logs in place with absolutely no movement.

Post by: Crusarius on April 10, 2019, 01:03:18 PM
So since i haven't put the final coat of paint on the carriage yet I decided to make some improvements.

One of my complaints I had from the beginning was how much effort it was to lift the head. So I added cam followers to the mast. Using something similar to @proptorudder (http://forestryforum.com/board/index.php?action=profile;u=40241) posted at reply #303. Now instead of gouging and scraping the steel off each time it goes up or down it rolls nice and smooth. Takes quite a bit less effort to move it as well. Took the raise time from 2.5 minutes to roughly 1.5. 

Unfortunately in the process of adding the cam followers that added some more issues. My threaded rods now interfered with the cam followers. I was not able to have a final cut of less than 10". So I ended up moving the threaded rod forward with a 1" spacer. This may have helped make it go up easier because now it is closer to the heavy part of the head.

Now with the threaded rod 1" further forward the chain going across the top interferes with the muffler. 

So now I am working on redoing my chain setup to clear the muffler on the engine. 

In the process of redoing all that I decided to make it dual width capable. Now I am able to run 158" or 176" band. If my math is correct that gives me a 41" cut width.

Once I get the remainder of this fix done I will tear it apart and put final paint on it.

Cam follower on the mast. you can see how the paint and steel was removed from rubbing before the cam follower.

Finally got my rotary table setup and working. This is machining the spindle I am making for the chain relocation. I used a cam follower a block of steel and a 3/4" bolt with 2 sprockets. See below.

Here is what adjustable bracket for the chain looks like. The plan is to have a common chain run across the back of the mast with 2 short ones going to the threaded rod. This will make adjustability much easier.


(https://forestryforum.com/gallery/albums/userpics/45059/IMG_20190407_161617961.jpg?easyrotate_cache=1554915896)

Here is the finished spindle without the sprockets. I need to finish machining the sprockets and put that all together.

I also forgot to mention above I made the lifting blocks on the threaded rod float to take up the minor bit of deflection in the rods themselves.

i enjoy reading what you are doing to your mill, I would love to have the skills you have on the machine. Weld I can do some fab work ok machine work  not very good just enough to be dangerous, bought a smithy 3/1 mill back in 96 never mastered but was able to do some machine work when I built my mill. But age has become a factor in comprehension ;D

Thank you. I really appreciate that. It is kinda weird thinking about my skills, to me it just comes natural. Maybe its just because I never really was able to just go out and buy stuff. But I sure do enjoy the fabrication. I really love to teach, and showoff my work.

This thread is therapeutic :)

Was the interference with the threaded rod due to the cam bearing diameter or lower threaded rod mount?
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on May 03, 2019, 08:46:12 AM
mostly the lower mount. but there was one point the diameter made the clearance very tight. as in paper fits through but nothing else tight. It did not actually touch but was close.

I wish I had slightly longer threaded rods then I could have eliminated the standoff.

It's done!!!!!! Just finished tweaking and re-aligning after paint. Now just need to cut something and see how I did on my alignment.

I still need to make adjustable toe boards, and log loader/roller but those will get bolted to the trailer.

Wide setting (176" blade) without guards cause I forgot to put  them on. They do fit.

Narrow setting (158" blade) with guards.

Here are some of my first test cuts after finishing the mill. It just happened to be a random walnut tree branch I cut into 1/2" slabs. My wife wanted something like that for a project and it was convenient and easy :)

Definitely cutting very nice. Extremely happy with it. Still pretty impressed since I had only ever seen a few sawmills and never run one before building this.

Of course now that I have built this one and used it the next one will be very different.

Sweet. I would love to see what you got. I know my stuff is not perfect. Some of it works for me but will not work for other ppl. I always like new ideas.

Don't be afraid to start a build thread. Then we can all get involved :)

still unsure if the threaded rod was the right solution for raise and lower. Lowering it is perfect. raising it is to slow.

Move the engine to the back side to change the rotation of the blade. Right now I have to flip all my blades since it runs opposite of woodmizer. 

Probably more things but thats all I can think of right now. 

I do have a plan for V2.0 in my head that I would love to play with but this one would need to be sold first. V2.0 will have a bigger budget and hydraulics.

I finally got around to remembering to take completed pics. I have been using this for a good amount of time now. I am still very happy how it turned out. I do have a list of things I would change that will probably be incorporated into V2.0 if somebody offers me the right amount of money for v1.0.

It definitely does not flex at all. and with all 8 trailer jacks down I barely notice any movement. I was a little concerned at first but not now.

If my build comes out looking half that good @Crusarius (http://forestryforum.com/board/index.php?action=profile;u=35059) , I'll be thrilled.

Right now, my sliding roller guide does not have the vertical support but will just cantilever from the sleeve. Do you think the vertical support that slides along with the guide is necessary?
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on September 16, 2019, 11:13:45 AM
on mine it totally was. I modified it to be dual width so the length the arm was cantilevered was excessive. Without the support when I would tension it I could watch the guide move up 1/8".

Thanks for the time it took.Through your post I noticed a few others building mills too with variations of the LINN, great work also.I am gonna read this entire post a couple more times before I start mine.Thanks again.

So curious, do you use this as much as you thought you would? (assuming this is your first mill)

I guess my biggest misconception is how fast I could mill logs. I have a pretty healthy stack, and after the first couple, all I could think was "man, this is gonna take a while. I need a bigger mill." LOL
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 15, 2019, 09:13:14 AM
I have a big pile of logs waiting to be milled. Unfortunately milling is challenging with a manual mill. Trying to figure out what the log wants to be, avoiding stresses in the log, and actually making smooth cuts. 

Once that is done, now you have a pile of lumber. Now what? 

Well we have to stack and sticker it. Crap! forgot to make stickers or ran out. Now need to make stickers. Great that is done. Now where am I going to stack this pile. 

Oh yea I can put it over there. Hmmm do I have a skid? Nope. crap need to make a skid or find one. 

Now that I got that taken care of I need to move all this stuff out of the way to get it over there. Ok, so we spend another half a day moving stuff to make a nice place to stack wood. Great. 

Crap I just blocked in my other pile that I need to get to. I just cannot win. 

Ok, lets move that pile again. Good now it is out of the way. Of course its not stacked the greatest to put another stack on top. Ugh I can never win can I.

The little story above is a normal day milling for me.

So the answer to your question is. No. I do not use it nearly as much as I thought I would. But I think the main reason for that is the rest of the work involved in making lumber. If I could just load logs and cut them into lumber My pile of logs would be gone already. But unfortunately, its all the rest of the work involved that takes up the most time.

True. It's been said many times on here: sawmilling is a lot of material handling with a sawmill in the middle. 

Eventually the handling and storage issues get to be routine and it gets a lot more efficient. Getting a good stock of stickers also helps. About 10,000 is a good numboer.

I had two people tell me, "the sawmill is the easy part."

I now know what they meant.

Post by: btulloh on October 15, 2019, 09:41:31 AM
True dat!  

The goal is to make the other parts easy too. That's a bit tougher for a hobby guy like me but I enjoy the challenge. I can't really justify some of the toys like a telehandler, fork lift, unlimited storage, etc. 

Adding the solar kiln made life a lot easier. 
Title: Re: Crusarius’ sawmill build - started with Linn Lumber basic kit
Post by: Crusarius on October 15, 2019, 10:07:38 AM
Solar kiln is on my list. I also need to make an actual lumberyard I can access a little easier. Right now everything is deposited around the trees on my property. I have ditches all around those so I have to drive through those to get to the stacks. Makes a big mess.
