All I can offer is encouragement. I am not a builder and if I was,by the looks of things,encouragement would be all that I would still offer!!
That sure does look good. Looks like you have done this a couple times. :D
Welcome to the forum and good luck with that timber frame camp.

Crusarius..... I machined some Teflon inserts on my rails... rails are 2 1/2"X1/4"...

 HillTop366... got the wheel at a local scrap yard $50 each... not sure what they were used for??...I'm thinking about putting a 1 1/2"blade!! hopefully i'll get feedback on this.. tks for the comments..much apreciated thumbs-up
Title: Re: band saw mill project
Post by: Southside on January 14, 2019, 07:16:26 PM
A couple things come to mind on your band wheels. First are they rated for the RPM you need to run them at? Most bands run at 5200 or so FPM for reference, you can reverse engineer your RPM from there.

The second thing I see is that material on the wheels is going to wear causing issues with tracking and tension, but more so when a band breaks and tears into it you will have a problem that can't be fixed in two minutes. 

The build looks great, and I am not a machineist, just my opinion on the wheels from a guy who runs a mill. 
Title: Re: band saw mill project
Post by: Tom the Sawyer on January 14, 2019, 07:35:21 PM
I'm not a builder but I too would be concerned about the wheel material holding up.  What will you do when a broken band takes out a chunk of the surface - it will probably happen.  

It appears that they are about 1 3/4" wide and you mentioned trying to run a 1.5" blade.  Remember that there needs to be room for the set of the teeth to clear the wheel, usually by tracking on the forward side of the wheel (1.25" blade on a 1" wide wheel).  

The other concern is that wider blades may be made from thicker stock, .055?  Those wheels appear to be on the small side, maybe 16" diameter.  To get 5200 fpm, they'll need to run at about 2500 rpm.  A 19" diameter wheel only need to run at 2100 rpm.  Not only does a smaller wheel need to run faster, it also means 20% more flex cycles within the same period of time.  Smaller wheel + thicker band stock = significantly reduced band life. 
Title: Re: band saw mill project
Post by: Vautour on January 14, 2019, 07:54:19 PM
tks for the replies guy.... I will be adding a rubber band over the Teflon so the blade never touches the Teflon.. and the rubber band can be changed just like a V belt... wheel sizes are actually 21"... hopefully that won't be a major problem... thanks again :)
Title: Re: band saw mill project
Post by: Southside on January 14, 2019, 08:36:50 PM
If possible I would test run that set up before you build everything around it, a few have tried those orange "band saw tires" and the results have not been good.  Also, when bands break they do so in very creative ways, they will jamb behind wheels, into the covers, out the dust chute, they will cut V belts and even drive belts so just be prepared.
Title: Re: band saw mill project
Post by: Ljohnsaw on January 14, 2019, 08:42:40 PM
Are they urethane or rubber?  Pretty tough stuff?  Since you have such a nice lathe able to swing that wheel, I'd suggest cutting a V groove into it (just like a pulley) and mounting up the equivalent of a B57 belt (will depend on the final diameter).  That would give you the crown you need for teeth relief and tracking, and a tough, cheap and easy to replace belt.  The B57 belts fit loose on the WM mills which allows them to throw off any sawdust build up.

Calculate your necessary RPM for your mill and run them up to 20 or 30% over that on your lathe and see if the yellow tread holds up.  Might want to put up a guard around the head! ;)
Title: Re: band saw mill project
Post by: Darrel on January 14, 2019, 11:37:54 PM
Those wheels being almost 2" wide would accommodate a band 2½" wide, maybe even 3". The tooth, including the bottom of the gullet needs to extend out beyond the edge of the wheel.  By time you do that with a 1½" blade on these wheels, you will be using well under ½ the width of your wheel. I'm not sure how well that will work or what problems if any it will cause. Who knows, it may work just fine and when one side of the wheels wear out you could turn them around. If it were me, I'd look into it. 
Title: Re: band saw mill project

Thanks for the info Vatour, that is going to be a monster when you finish it. What are you planning for cut width / blade length?

Looks pretty sexy to.

            Hi Guys.... Posted last night but didn't go thru?...Southside..  I will spin theses wheel on the lathe again at a higher speed  ..Safety is priority..    Ljohnsaw..they are a tough glued on urethane so im pretty confident they will hold!! had though about doing the V belt thing but cutting the V grove would have cut the urethane in two pieces and weaken up the Teflon.....Darrel.. if I can.. 2"would be great which means I could cut faster right??..it all depends on the width of the rubber bands I will on the install over the Teflon...(auto.serpentine belt) perhaps!!...Crusarius  I've got 51" between the rails and blade length is just under 18' .. losta 4 feet dia. trees aroud here.. thumbs-up

Title: Re: band saw mill project
Post by: Darrel on January 16, 2019, 10:34:51 AM
There are advantages to wider bands for sure, speed is one and less tendency for wandering being another.  Cost, however, is not an advantage. If you are going to be into high production than go wide and a bit thicker, say .065" - .070". Heck, you might even be able to do something a bit radical and get a 3" wide band with teeth on both sides and cut going both ways. From your pictures it looks like you have the skills needed to pull something like that off.

I like the idea of a double cut mill, always have, has anyone seen how the boards are removed from a horizontal double cut mill?  
Title: Re: band saw mill project
Post by: Crusarius on January 17, 2019, 10:24:05 AM
I was very intrigued with the idea but was trying to figure out a way to do it with 2 blades. Wasn't really working out in my head so I gave up.

I would say like you normally do with a manual mill, to the side.  Or, use a drag back that takes two boards at the same time.  i.e. cut forward, drop, cut backward bringing first board back, drop cut forward, drop, cut backward bringing two boards back...
Title: Re: band saw mill project
Post by: Southside on January 17, 2019, 03:47:47 PM
The issue I see with the drag back is if the boards are a different thickness then you are  going to hang on the one you are back cutting if it is a thicker cut than the foward cut.  To the side defeats the purpose of cutting both ways I would think.  Maybe that's why double cuts are usually angled to the side with a take away conveyor.

Post by: Al_Smith on January 17, 2019, 04:53:53 PM
In regards to the urethane ,it is really tough stuff .We used them for traction rollers to move cast iron blocks for large v8 engine blocks at one time on roller conveyers in an automobile engine plant and they held up very well .Fact I used 4" rollers on a DIY seam former for standing seam roofing .

 Hi guys...i'm in the process of building my band guide wheels and wondering what size bearings i should use?... guild wheels are 2.5".. i have bearings with a 5/8 inside bore but could go bigger.. maybe at lest 3/4" ID...not sure what most manufactures use??... tks
Title: Re: band saw mill project
Post by: Bandmill Bandit on March 05, 2019, 08:12:37 PM
i will go dig through my parts bin and check but I think mine are 6202s  with 2 in each roller. There is a double race version that works better in my opinion but doesn't work well if you want to make them greaseble

.. tks Bandit... was checking what size 6202s are and seems to be 15mm or 5/8''... so since i had bigger rollers i bought the 6203s which are 3/4''...not sure how greaseble bearing work but looking at videos of cooks and think the two bearing are squezzed together and grease is pumped on both sides to catch the saw dust... i think :-\  
Title: Re: band saw mill project
Post by: Bandmill Bandit on March 09, 2019, 09:36:03 AM
6203 s is what mine are. 

To make them greaseable you take out 2 of the seals and then install the bearing so that the missing seals are in the center of the roller seperated either by a spacer OR with the roller machined with a shoulder rim that the bearings seat against when installed from either side of the roller. drill the bolt to the proper depth and drill a small hole (1/8th is lots) through the the bolt to T to the horizontal hole and you got a grease able roller. 

grease in that location CAN be a more of a problem then a solution as over grease will wreck the seals and allow sawdust to get in the bearing. OVER GREASED bearing are a far more costly issue then permanently sealed HIGH GRADE bearings hands down.

just finished turning my roller guides....@Bandit... that's what i was thinking of doing.. but you must have small hole in the spacer for the grease to go thru... i was also thinking about making small holes (seep holes)on the outside of the rubber seals as you grease you will release some pressure and add grease on both sides of the bearing assembly and with washers on both sides to hold the used grease there to captivate the saw dust...hmmm

There is a product called case nite that you can use to harden the OD of your rollers. It's a powder and you heat the steel then dip it in the powder. It works
Title: Re: band saw mill project
Post by: Crusarius on March 09, 2019, 06:15:46 PM
I would stick with sealed bearings and be done with it. Most cars on the road have sealed bearings and have very little issues with quite a few more miles on them.

as for hard enough. anything will wear out they may just wear out a little sooner. I would not be overly concerned. you can always buy a set of rollers only.

What material did you use for the rollers?
Title: Re: band saw mill project
Post by: Bandmill Bandit on March 09, 2019, 08:52:01 PM
Case hardening works well in a lot of applications and is not real difficult to do. The secret is getting the rollers to right temp EVENLY. can be done with a rosebud heating tip on a torch or a small forge. 

As for bearings, the best you can get in SKF or NTN are my go to bearings and what I keep in my parts box.

I may be possible to get 2 double row bearing in those rollers. NOT that you'd really need that but the mill may wear out before those bearings would if you did it that way. They definitely would not over heat easily.

Kasenit has not been available for years.  A similar product is Cherry Red or Bownells sells some private label stuff.  None of it gives the deep case blade guides require.

There is a method that infuses carbon into steel by burning something like leather it in a sealed packing box.  Google it for directions.  You also might be able to find somebody that does it commercially.

No Vantour they are not. I switched back to sealled after a one season run of the greasables.
Too messy for my liking in that location. I just use the best possible grade marine type bearing I can get. Initial purchase is more but the longevity far out values that initial purchase.

I wouldn't be concerned about the urethane wheels longevity. I have seen rotating urethane coated cylinders outlast steel cylinders in much more demanding environment than your mill will ever experience. there  are also companies that will resurface them but at what cost? As far as your blade guides, make them out of 4140 steel and they can easily be hardened.

.........@ Crusarius...i would Not worried about low end torque..for example this motor has 50hp at probably 2000 rpm... so i'm gonna run it at about 1500rpm with a 6 inch pulley at the crank...motor is bigger than i had anticipated ..i worked in a scap yard and some car had some way smaller lighter motor..

If that reduction unit is a worm gear you won't get an overhauling load heavy enough to over ride it .Big heavy link chain takes a lot to break it .
I suppose there's options for a back up dampening  device in case of a failure for safety reasons .Could be long air cylinders with check valves which would act like shock absorbers or a ratchet /pawl device ,inertia brake .You'll figure it out I have no doubt .

It's none of my business but I would think trying to adapt a fairly modern automobile engine to run as a power source to anything would be a gigantic pain in the behind .Firstly it would have to be governed which would be a big enough deal if it were carbureted and a bigger pain if were fuel injected .
Then you have a cooling system that doesn't have the benefit of having air move past it like on a car .
In addition running at a lower RPM than in a car it won't produce the same HP .Probably enough but it won't be 100 HP .For example my old Oliver crawler has an industrial version of a 1954 Chevy six only more robust ,bearings etc .The Chevy was around 90 HP the Ollie  is about 34-35 .I'm not saying it can't be done but it's going to be a job .Nothing mechanical is impossible though . ;)

that is what I'm facing right now. adapting an industrial 4cyl diesel, plus the cooling, to run my mill. it is though rated for 100 hp @ 2400 rpm, which i calculated the pulley size to run at 2200 rpm, since that is what the high idle solenoid was set at, according to the tach. i was able to adjust the linkage a lil and get around 2350 rpm. my first challenge is to get it running again. i yanked all the wiring and the generator head out of it, and was able to get it to run afterwards, but just long enough to to run the fuel lines dry. now, i can't even get it power to the switch, yet all switches test fine, wires test fine and i know iv got 12v to the system bc i bump it over at the starter. i HATE electrical.  :'( :'(

Well, after starting at it for the past few hrs and tracing wires, jumpering terminals and accidentally burning out some kind of rectifier that was brand new, trying to bypass 2 safety switches (oil psi and temp), i think i might have figured out how to rewire it. I can get it to start but the starter solenoid stays engaged and when i rmv the jumper wire, it dies. This thing has 2 starter relays (old ford fender well 4 post starter solenoids), 1 for the eng and 1 just for the injector pump fuel shut off solenoid. 
It has 2 cannon plugs that i want to keep but i think in order to rewire and bypass those switches, im gonna have to splice wires in and out of the cannon plugs, bc i dont have any pin/socket instal/rmvl tools. If the splicing works, i'll have to add wiring anyhow, so ill use the splice joints to add in my extra length of wire. 
The odd thing is though, all power in is routed to the starter solenoid first, then off to other areas, instead starting at 1 of the 2 relays, then to the starter.

Some times if you can trace the problem to a specific component ,relay for example or a circuit board that has a part number you can trace it down using that .Ford GM etc do not make these components they buy them from someone else .They could be just a generic item .
I've done this on my own stuff and at work before I retired .Might take some research time on the net but you can sniff it out just like a hound on the trail .Plus the more people you can bypass on the supply chain the less expensive it is .
The one exception might be anything made or engineered from Germany as they have a mind set of specifically OEM designed components .It's well made stuff but you are limited to almost have to go through them for any repair parts . You can reverse engineer sometimes but you'll often have more time and money in it than just biting the bullet and paying the OEM guy .

Or sometimes you can re-engineer it like my tractor glow plug system, The relay stuck on and killed the battery, I had not used the tractor for a week so the battery was toast the relay was overly expensive so I put less expensive generic relay on it but it turns out the relay did not draw enough power to operate the timer properly so I bypassed the timer and put a momentary switch on the dash ( press switch to activate the relay and count to 10) then after a few years the relay stopped working again so I bypassed everything in the glow plug system and put a high amp momentary switch on the dash running new wire from the relay fuse to switch to glow plugs. 

Charles, for your shutting off problem or engine only running on start, I have had problems with one that did that it turned out to be the "run" contacts in the key switch. It had a plastic ring the contacts are in it would melt a bit and eventually get covered over by the turning action of the switch. The switch lasted 600 hours, the second switch lasted 600 hours and it started acting the same (randomly shutting of the fuel) so I bought a new switch which improved it but not completely I ended up changing out a corroded fuse to completely cure the problem.

So the Readers Digest version the cause was low voltage to the fuel shutoff.

according to the troubleshooting it is the toggle switch. i jumpered across as it said and it cranks but shuts off when jumper is removed. when i shot the switch under ohms with the beep selected, it would show continuity when in the start position and then again in the run, but noting in the off, even though there was no power getting to the panel and all works are connected. or at least i think they all are connected. napa didn't have the 3 pos toggle, so I'm gonna try a few other places. i think burned out whatever a starter solenoid rectifier is. not even sure what it is or what it is used for within the circuit. gonna do some research and see if i can manage without it.

Well I figured you can do it .It's just a general statement regarding what a person could run into adapting mobile engines to stationary engines .I mean decades ago a Buick straight eight engine was the cats meow for circle mills .
Fact I'm in a quandry trying to decide what to use myself on my build .I've got options .15 HP twin Wisconsin ,16 HP Briggs ,31 HP VH4D Wisconsin ,10 HP three phase electric motor . The later would most likely be the best option .
I could just lay down the money and buy a small mill like a Woodmizer if I wanted to .I kinda figured anyone can do that but not everybody could build a mill .----it's all about the challenge---- 8)

well, i was able to finally get the engine to run after removing the jumper lead. i replaced the switch with a 2 pos (on/off) instead trying to source the same switch, other than using a keyed ignition switch, which as of now, i don't have room for. I'm thinking maybe the relay is bad, or i don't have something hooked up like it should, but i followed the example i found on google images. so, I'm gonna load it up tomorrow, chain it down and take it to a performance shop about 4 miles away, which i was suppose to have done this past summer. i also found a fan with no predrilled holes, so i can make the bolt patter the same as the factory, plus it is a puller fan, i just hope it moves the volume of air to keep the eng cool.

@woodpecker52  I hear what you are saying. I was married with kids before Wood-Mizer came up with the first real innovation in portable sawmills in a very long time. Thin kerf narrow band. Most of what we see today is just variations of that. There are also the swing blade mills that definitely have their advantages.  Coming up with something new that is also an improvement on what is out there is a difficult challenge for sure.

Is your vertical guide rails DOM tubing or turned on your lathe? 
I ran into a similar issue using uhmw similar to your design except i was using sq tubing. I ran into binding issues going up and down. It was NOT concentric enough for the design. 
I thought about getting some 2 1/4" 4140 and having it turned concentric and using some bronze bearing installed in another piece of tubing. But after calculating price of material and machine work, thk linear rails and bearings were cheaper. 
For rails and bearings plus fuel to get the rails, it cost $600 as where the other route would have cost $1000.

Post by: charles mann on December 10, 2019, 09:59:52 AM
I cant speak for cooks mills tolerance, but .015" is a lot of slop. When i had the hinges and pins machined for my log arch, i asked for a .015" tolerance. I got some shim and started shimming to a a couple thou tolerance. I figure nmt .005 would be plenty, but i could be very wrong and .015 would do the trick too. 

If you go solid or even dom round, you are planning on using roller bearings, not bronze bushing bearings right? It would make for replacing the bearings much easier than disassembling the entire sawhead to replace bearings.

I had thought of a similar thing using cold roll steel round stock and aluminum bushings made from salvaged hydraulic components with a 1-1/4" bore .If you grease the rods and kept them greased they wouldn't rust . 2.5" hydraulic  cylinders for the lift .I've actually got some 2" which would be enough no more than a saw head would weigh .They are 45" stroke I think .--It's still in the "thinking "stage---

I did some research on those K&N filters.  They allow the engine to breath more for more horse power.  That being said, they are fairly small so that means they must be fairly porous to let the air through.  To me, that means lots of stuff can get through.  I did read some reports about engine wear being higher.  So, I would stick to a normal pleated paper/cloth filters, or even an oil bath type.

Vatour. a prefilter is just a fine screen that goes over the main filter. I run one on my jeep and it is amazing how much fine silt that will capture and keep the filter much cleaner. Makes for longer intervals before needing to clean the filter. Plus alot of times you can just remove the prefilter shake it off and put it back on without having to do a full filter clean.

Search google for K&N prefilter you will see what I mean. 


As for K&N filters causing more engine wear because they allow more through, This I cannot confirm. My jeep has a ton of desert offroad miles on it and I have never noticed any issues. K&N air filters are actually soaked in oil,. The oil catches most of the particulate. If it is dry it will not work as well. Plus the dirtier they get the better they filter. But that defeats the purpose.

Search for for "filter wrap" on K&N website, there are nylon mesh bags as well as foam covers for their filters. The foam come in oiled or dry, the nylon bags pre filter and are suppose to keep moisture out.

That makes a whole lot more sense.  The "research" I saw on the K&N did not mention or use a pre-filter.  That would seems to make them as breathable as a normal paper filter.  Looks cooler with a K&N.

I have been impressed with the amount of dust and silt on my prefilter and how clean the main filter stays with it. Definitely a must with sawdust.

I dont think 8sec/ft is a bad idea personally. When you are adjusting height between cuts, slower movement makes small adjustments easier, IMO. Very cool build either way!

Need to make down slow and up fast. Thats where I am at right now.

@ Hoopty .. i think you need as fast as possible to up but when you go down you need fine adjustment and use a speed controller.... that (B)cake looked delicious.. mmm

Eh. I don't disagree, but I think its a minor detail in the whole operation scheme. I just upgraded to an electric winch to raise/lower from a hand crank boat trailer winch. It's amazing, and I'll measure the time to travel 1' just for the sake of comparison

Also, thanks!

Finally Got my engine running after sniping 90% of the wiring harness(on the floor)... alternator is not charging, lost my 3sec fuel pump delay along the way, electric fan may not be working but these are easy to wire up independently,... happy with the outcome tho.. not sure i'd recommend :-\ haha

Is it quiet as you thought or louder?

I still like the idea of doing car engine. I have a 1.9 twin cam saturn that would probably work well. it is mated to a manual transmission that could also work for blade drive.

@ Darrel...  tks ... it was pretty nerve wreaking yesterday going into uncharted territory while doing the snipping. smiley_beertoast(those are root beers by the way) i don't drink
@ Hoopty5.0..... Is it quiet as you thought or louder?... actually it is louder than normal because it has one of those Hollywood mufflers that the young kids put on there Honda to impress the chicks.. still not loud enough to use ear protection and still have a conversation next to it while it's running, but i'm gonna fab some type of baffle insert to bring down that noise or change the muffler altogether... 

   
   @ Crusarius.... my next project with car engine would be a FireFly/Metro 3 cylinder with CFI (Central fuel injection)made like a carburetor but less complicated than a multi-port EFI... the older micra's would be good choice also (very small and lightweight).. i'm looking for some of those car's now and eventually use the engine and drop it into a cheap side by side for hunting..

Vautour, after this pandemic thing is over we need to meet. I have had many interesting crazy ideas that mimic yours :)

Since I do not get much use out of my snowmobile that has been very close to being turned into a side by side for a while.

I also have a pair of neon srt4's that need some love.

Don't have a passport :D...once i finish my Dodge Truck with camper in the back i want to visit many States in the mid west... i was thinking how to eventually add a homemade "accuset" on my mill and this guy on YouTube "Mike Festva"  came up with simple idea...check it out if you haven't..

 charles mann.. hope everything pans out good for your return home.. and yeah you can smuggle me up in your red helicopter, i'd like to stop in Wyoming and check out that large tree stump they call "devil's tower" and measure the diameter so i can build my super mega wide band saw :D... afterwards we could fly over the south border and check out the progress on the WALL... man that would be a trip of a life time.

(https://forestryforum.com/gallery/albums/userpics/53405/20200403_153211.jpg?easyrotate_cache=1585947188)Well i took one of my smaller jack shaft off that had a gear reduction ratio and went direct from gear box to main jack shaft and went from 8 sec/foot to 5sec/foot for lifting my head assembly...so now i have to get a heavier chain and sprockets and  debating getting either a #80H chain or a double #60 chain(any thoughts on which is stronger would be appreciated).. and while i'm buying new sprockets i'll get different ratios to up the speed a bit to probably 3-4sec/foot.         .....@ charles mann.. i think i'll pass on the helicopter ride..low on cash at the moment :D
