Title: Log arch build finally complete Video added )
Post by: 21incher on March 27, 2014, 03:18:26 PM
Today it finally got warm enough for me to go out in my shop and start building my log arch. I had some leftover tubing and steel plate from my sawmill trailer build and a couple of 5 lug 15 inch wheels. The only parts I am looking for are the hubs and spindles, It is being built to handle a max 24" x 12 foot log.

The forward support angles. Hopefully it will pivot and drop down to load the log when done

1/4" steel plate supports cut in about 2 minutes

Welding the l.h support in place.

The supports have pockets to lock the log support chains in place. This is as far as I got today but will post more pics as the project continues.

It is a CNC table that I designed and built a couple of years ago. Never got good cuts though until last year when I added Digital torch height control.

Nice looking arch. Workmanship looks top notch. Have plenty of support when you install spindles! Lots of stress there. I like the keyhole notches for the belly chain, but a small caution. Install rings on each end of the chain, because it will come off while traveling empty! Don't ask me how I know this. I had grab hooks on each side of mine, and lost the first chain, then welded the end link on one side and left grab hook on other. No more lost chains. Keep the pictures coming, and be safe.    Andy

Mark I have no idea on the hubs yet. I just started looking on craigslist for a old donor axle and hubs ( hopefully with electric brakes ) but if I don't find one I will have to break down and order new parts.

Andy once I get axles there will be reinforcing brackets added to handle the stress plus I will be cutting other braces for the frame. I plan on mounting a couple of old ammo boxes on the tongue to keep the chains in when they are not being used. This will most likely take a while to complete in my spare time so please bear with me.

Today I had some time to start on the log lifting claw. Originally I had the stupid idea to tilt the frame to load it, but after mocking it up I found out it will not work. So instead I decided to go with a winch and a claw. Here is the start of the claw


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0810.JPG)
Designed and plasma cut the claws.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0812.JPG)
They wound up being pretty beefy because I only had 1/4 plate. Wish I had some 1/2 inch.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0814.JPG)
That is a 16 inch diameter plate, the jaws are designed to handle a 24 inch diameter log weighing 1500 lbs.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0815.JPG)
This is where the assembly will mount when done.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0817.JPG)
shown in open position to clear a 24" log. They will drop with a winch to load.

Working on the claw this morning. Cut the pivot plates and lifting links.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0825.JPG)
Starting to look like a big claw.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0827.JPG)
Claw in closed position


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0828.JPG)
Pivot plates for the jaws cut.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0830.JPG)
Lifting links plasma cut.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0833.JPG)
Only 1 more set of plates and the claw will be complete. Still have to make some bushings, nylon washers, & 3/4 pivot pins. Then I must find a hand winch to raise and lower it. In the future I may add a electric winch so I don't even have to get off the tractor to load a log. Next comes the front log lift / cradle.

When building an arch from square or rectangular section steel, say 2x2 or 2x4 inch, would 3/16" wall be sturdy enough? Or should I go to 1/4"? I doubt the arch would ever be used to carry more than a 3,000lb log.

I am using 3 x 4 x 3/16 wall for mine and only plan on a 1500 lb max log and that is what I will test it with. There still is more bracing to be installed. The material is really dependent on the design and bracing you use. You could probably get away with 1/8" with a good design. The highest stress area will be where the axles mount. and the forces will quickly increase if you are in a rocky area. Also from what I have read the 1" and 1  1/4" axles should only be used with 12" and under wheels. 15 " wheels require the larger stepped axles when there are no springs to help absorb the forces.

Another couple of parts this morning. Cut the pulley brackets that will raise and lower the claw.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0848.JPG)
Top pulley brackets


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0850.JPG)
Made some spacers and welded the asm together.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0852.JPG)
Next I have to make the idler pulley for the cable to raise and lower the claw.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0855.JPG)
This is where the claw will hang. Over center springs will be added to keep it open when it drops and clamp it when down. Next I will pickup a manual winch and add a mount for it and pulleys. hoping to be able to operate both the front and rear lifts with 1 winch.

I went with 1/4 and 5/16 tubing on my arch.The stub axle sockets are 1/2 inch stock.My Dad always overbuilt things.He said if you are not sure go heavier.There are plenty of arch builds on youtube, some good ,some bad.One home built for sale was 6 feet high,a sure tipper.A tipper will take an ATV with it.

On smooth ground,which I sure don't have,you might get away with a light one. Uneven ground and a rock or a stump,and all the weight goes to one side,you will be glad you over built it.

Today I cut the mounts for the cable pulleys that hold the claw.

The bottom one is sandblasted.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0859.JPG)
Welded them in place


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0861.JPG)
Making the ball bearing cable pulleys next and then a couple more braces.

Another green machine. I have a gallon to use up so the price is right. Today I turned 2 of the cable pulleys and pressed in the bearings and worked on finishing up the links.

Post by: Delawhere Jack on April 01, 2014, 05:36:20 PM
I noticed the Magic Man left the backbone of his arch projecting about 30" to the rear of the arch. Seems like this might aid in securing logs after lifting them with the winch. It would let you secure them behind the center of gravity of the log. Think I'll incorporate that feature.

Found an axle yesterday. 3,500# Dexter, 2" offset with hubs (sadly without wheels). The spindles are mounted into sections of 1 1/2" x 3 1/2" bar stock. I'll cut these and leave about 3" to insert into 2x4 tubing for the arch.

Been laying it all out on graph paper this afternoon. I want to have it all figured out before I start cutting steel.

All along I've been planning to make the arch so that it can be disassembled and carried on the flatbed, so I can take it and the mill to a job in one trip. The problem I envisioned was trying to lift the main arch section up and onto the flatbed. Then last night it dawned on me. The flatbed has stake pockets on the sides and the rear. I'll weld some hanger brackets on the arch, above the wheels, so that the arch can be lifted one side at a time and secured on the back of the truck.

21, have you gotten any orders for your lifting tongs yet? Looks pretty slick. You may be hearing from me about a set of those.  ;)
Title: Re: The start of another log arch build
Post by: 21incher on April 01, 2014, 07:04:49 PM
Delaware Jack I don't want anything to stick past the wheels so I can just flip it back and stand it up for storage. There is still another set of chain anchors and braces going on the rear of mine. The biggest logs I cut will be 12 ft and I always want weight on the hitch so I will always load with the largest side to the front. There will also be a lift on the front that will operate with the same winch and pick the log up level (if I am lucky) so no straps will be required, just a couple of chains to set it on. You have had better luck then me finding a axle, did you get electric brakes on yours? I am hoping that my lifting claw works as I envision it but don't get your hopes up until I test it. Can't wait to see pictures of your build. Mine will most likely slow down now until I find a axle and order some drill rod for pins, plastic for spacers, and pick a winch. Then I can begin work on the tongue asm.
Title: Re: The start of another log arch build
Post by: Delawhere Jack on April 01, 2014, 08:33:40 PM
No brakes at the moment, but they can be added later. Designing for a max 36" log, and max 16' fully suspended (one or the other, not both). It should be able to handle 3,500 lbs but I doubt it will ever need to carry that much. In nearly two years working portable I can count on one hand the number of logs that exceeded 3,000 lbs.

I just got this winch for my arch.  LINK (http://trailerpartssource.com/Jacks-Couplers-Winches/winches-accessories/two-speed-winches/Fulton-T3205B0101)  It has a 3200 lb lift, two speed, and has a brake.  I did not want to have to depend upon having a battery plus deal with the additional weight.

For my use, the overhang has proven to be useful.

That's the same winch I used when I had the manual mill. Very well built and heavy duty. It went along with the Turner mill when I sold it. Guess I'll be buying another one.

Lynn, I'm surprised that most arches don't have that overhang to the rear. If nothing else it could help avoid dragging a long log. Could also be useful to ensure that you've got some positive tongue weight, rather than having the tongue want to lift.

Post by: 21incher on April 02, 2014, 05:33:02 PM
Thanks Magicman for the link to the winch. It is the heaviest duty one I have seen. I may also go electric and put a plug on my tractor to operate it, still trying to decide.
Today I made a couple of brackets to support the log, hold taillights, and hold the rear Ash bumper ( I put a Ash bumper on all the ag equipment I build )


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0875.JPG)

They only have to move logs and I think yours would work great. This is a result of a long winter and having time to sit around the wood stove and scribble up ideas. I don't need it until fall, but if I needed it quick it would look different. Seeing the logs being loaded on the trailer by Magicman's functioning home built arch is what gave me the inspiration to start on my own. Magicman figured out the hard part of how to simply load logs on a trailer.

No luck finding used axles or even reasonably priced new ones locally so I ordered new 1750 lb Dexter hubs and stub axles today from etrailer. They even had a free shipping special.  So it looks like everything is on hold until all of the parts arrive.

Thanks. It is a fun project that has revolved about the claw idea. Originally I was going to build a crane with the claw to load my trailer and then I saw Magicman's post about loading a trailer with his log arch and decided the arch would be more practical and allow me to load any trailer. I keep all the dxf files and gcode for the parts so it will be easy to make replacement parts when things break.

Today I cut the mounts for the stub axles I ordered.

Had to use a piece of tubing to align everything for welding. Once the axles are welded in place the front and rear will be filled in with gussets.

The parts from e trailer came this morning. Ordered them last Friday afternoon so that was quick shipping for free. Also received the drill rod and UHMW for the washers. Got a chance to do a little more work on it today


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0891.JPG)
Got 3500 lb a set Dexter cast iron hubs, stub axles, lights and a wire harness.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0894.JPG)
Cut out and welded in the front gusset.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0896.JPG)
The axles fit perfectly into the brackets.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0897.JPG)
Welded the stub axles to the brackets.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0898.JPG)
Cut and bent 4 support brackets for the axles.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0902.JPG)
Welded in the brackets on the front. Have to flip it and weld in the rear ones tomorrow then the wheels go on. Getting pretty heavy now so I have to get help to flip it. Wound up spending my winch money on the hubs and axles so it will be a couple of weeks until I order a winch.

It will be a while before it is done and painted. The snow is gone and my yard cleanup, firewood splitting/stacking, and garden are going to put this on hold for a couple of weeks.

Got some time to work on it again while waiting for yesterdays snow to melt. Started on the parts for the front log lifter. It is mounted in the front vertical hitch tube.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0911.JPG)
The start of the parts. A UHMW polyethylene lower bearing block, the lifting shaft, top truck, and some old tubing for the vertical tongue.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0913.JPG)
The top truck is made with 4 cam follower bearings to guide the top of the shaft inside the tongue tube. It will keep the front lift from rotating. Had to weld on shaft collars  to lock it in place because the shafting is case hardened.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0914.JPG)
The lower bearing block gets bolted in the bottom of the vertical tube. The winch cable will double back and hook to the top of the shaft to drop both the claw and front lift and then levelly raise the log.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0916.JPG)
The parts out of the tongue tube.

Got a couple of minutes to work on it today.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0924.JPG)
Cut a couple of plates to reinforce the front upright and mount the front lift cable pulley


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0926.JPG)
Welded them in place


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0928.JPG)
Just have to add the hitch to the bottom next.

This arch is getting too complicated.My arch looks like a Logrite with fewer parts.Build cost was 200 bucks on mine.I have a worm gear winch that is a bit slow but there are no pulleys.Would have liked a 2 speed winch but used what I had on hand.Will the tongs handle 3 small logs at the same time?

I started to create a Logrite style arch but then decided to add some different ideas. So far I have $140.00 in it and have decided to go with a electric winch that will add another $120 to it. So the final cost will be under $300.00 plus the scrap material I had. This is just a fun project and as I will never build another I really don't how complicated it gets as long as it is simple to operate and gets the job done. With the CNC plasma table all the parts only take minutes to make so I am easily able to fab the parts no mater how complicated they look to you. And for the claw I will only be able to handle 1 log at a time because anything under 16 inches gets cut into firewood. Hopefully when it is done I will be able to backup over a log press a button and takeoff with no manual labor.

I'm curious about the sliding deal you built for the "front lifter".  How does it work and why is it there?  I may have missed the wheres and whys. This is going to be a slick rig whn you get done with out a doubt.  Exemplary work indeed.     8)

Thanks. There are 2 arms with teeth that have to be fabricated yet that will swing under the front of the log that attach to the bottom of the shaft. The log will always be loaded front heavy (for hitch weight) and they will help suspend and hold the log level so it doesn't drag on the ground. The cable from the winch goes through the claw pulley then wraps around back to the front and hooks to the top of the front loader so the winch will raise both at the same time. I plan on adding a garage door spring to the cable going to the front to balance the load.

Today I got a little time to work on the tongue. The arch will require a short tongue for maneuverability in the woods behind my compact tractor, and a long tongue for stability behind my F350 on the road. I made the short one from a couple of plasma cut plates, and the adjustable height / changeable tubing mount for the arch.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0991.JPG)
the short tongue


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0992.JPG)
Uses a std 2" x 2 1/2 Mount. Will adjust vertically in 1" increments.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0995.JPG)
Welded the mount on the arch. Sandblasted and primed the tongue.
Went to Harbor freight to pickup a 3500 lb winch and they were sold out so I wound up getting a 2500 lb winch with a wireless remote control and load break to mock everything up with. Hopefully it will work as I only need about 800 lbs of pull to pick up a 1500 lb log but the cable size is marginal for the load. The winch was only $44.00 with a coupon so if it works upgrading the cable on it will make it safe and my arch cost will drop to under $250.00.

Ask questions if you have any. And the most helpful tool I ever built was my CNC plasma cutter. Everything I built before it was square. The plasma cutter is also good if you weld something together wrong. You just put on the hand torch with a gouging nozzle and blow the weld away with very little damage to the parts. I wish I had more time to work on it so I didn't have to keep you guessing.

I did the holes on my Bridgeport because I wanted a precision fit. I drilled them undersize then reamed them so the parts would align without much shake. With plasma cutting there always is a very slight taper in the cut and some wander depending on direction of cut. I usually cut the holes .020 undersize and drill them out. Someday if I get time I will add a rotary axis that will allow me to cut tubing.

Today got the winch and LOGRITE mounted.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0996.JPG)
The mount for the winch welded in place.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_0998.JPG)
The winch in place. It came with a relay box and remote control that will work from 25 feet away that is worth more then I paid for the winch.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1001.JPG)
The front LOGRITE mount because you can't go in the woods without one.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1002.JPG)
The rear LOGRITE mount. Next a place to hang the stihl, some more chain anchors, and I decided to add a small battery for the winch so it is self contained.

You may want to make a latch to go over the front mount of the cantdog. Or make the grove deeper. I doubt it will fall out with a log in place. But empty the arch might jump a little. But who knows too. Lots of good ideas there.

The lower mount locks on the forged hook pretty good. You drop it in and then slide it back and the taper on the hook locks in the mount, Maybe I should add a bungee strap to be safe for highway use.

Thanks drobertson. It has been fun building.

Today I made a battery box for the winch battery


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1003.JPG)
Plasma cut a couple of sides and a piece of angle with some tabs welded on for the hold down.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1007.JPG)
Got the remote control box mounted and all wired. Got everything going up and down with no hand cranking.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1010.JPG)
Then I cut and bent the first piece of the front moveable chain anchor. Started cutting the tubing for the front lift. It is some kind of stainless steel that took the teeth right off my bandsaw blade so I will have to plasma cut it tomorrow.  Now the end is finally in sight. Another thing I found out today is when old tires have sidewall cracks and start to leak slowly, don't put a little extra air in them because the sidewall blows out five minutes later. Got to find some replacement tires for the arch now.
Title: Re: The start of another log arch build
Post by: 21incher on April 27, 2014, 04:20:37 PM
Finished off the front anchor today.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1012.JPG)
Got the gusset cut and welded in. Made the top plate.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1014.JPG)
It hangs off the arch ans is adjustable for short logs. There will be some uhmw plates to keep the paint from rubbing off and allow it to move along the rail.

That arch is better than factory made!! I am surprised you didn't build your own complete mill with the tools/skills you have demonstrated thus far, if you can think it, I am pretty sure you can build it!! Just curious about the wear points on all the moving parts, and the tips of your claw arms-did you heat treat any of it? Or are you not too worried since if anything needs replaced you can just whip out a new replacement part lickety split?  Again, awesome job and thanks for sharing with us 8)

Post by: 21incher on April 28, 2014, 09:03:21 AM
Thanks everyone. I have very little experience at sawing and joined this forum to learn more from the members. I can not contribute much to that area but I plan on sharing ideas in other areas that I can.

mad Murdock I bought my mill because I did not know of this forum at the time and most likely would have built one if I had seen the work of forum members. But at least I built a trailer for it. At this point in time nothing is hardened. If after getting it to work it looks like there are areas that need to be I will worry about it then. For now I will just spray some liquid graphite on the wear areas. This is a low use item that should not see much wear and tear. The part that complicates some areas is only using leftover materials for the build.

I am glad that some members are enjoying this thread as I was originally going to build it and then post a couple pictures of the finished arch when done so I didn't bore everyone.

I built a table that can cut 4 ft. x 5 ft. material up to 1/2 thick. and I think it cost me about

4k for parts  ( servos , thk rails, belt drives off of ebay, and new servo drives, encoders, and zero backlash gearboxes ).

.5k for steel and aluminum.

.7k for the digital torch height controller, I/o boards, PWM module, and cables. Which are required for a decent cut.

.5k for machine control and cam software.

3k for Hypertherm Powermax 45 with a hand torch plus a machine torch.

So I have about 8.7k  plus hundreds of hours building, wiring, debugging and reading manuals to get it functional. Most commercial tables that size go for around 10k shipped plus the plasma cutter so if I count the labor as a learning experience I saved quite a bit by building it.

Today was a rainy day that let me spend a good of the day in my shop. Worked on the front lift parts.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1028.JPG)
Got most of the parts cutout machined and welded. Had to change my ideas some to be able to support 500 lbs without flexing but it is pretty sturdy now. Still have to weld in some plugs to allow the jaws to screw on so I can change them out if they don't grip right.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1025.JPG)
This is the assembly shown with the jaws in the lift position.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1026.JPG)
The jaws will be open like this and up when you back up to load a log.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1024.JPG)
Mounted on the lifting shaft in the up / transport position. Will place a rachet strap around the log and arms to keep it from shifting when bouncing down the road.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1019.JPG)
Shown in the down position. The arms will swing partially under the log for lifting. Have to add some brackets, springs and a up position lock
, then get some new tires and cut down a tree to try soon.

Post by: 21incher on April 29, 2014, 08:38:42 PM
The tractor/loader with wheel weights weighs about 2500 lbs. and as long as it is in 4wd it stops quite well on hills with my landscape trailer behind it that weights about 1600 lbs. empty so I don't see a problem, but brakes can always be added if needed.

Seems like the rule of thumb is that the towed vehical not exceed the tow vehical. That would let you haul a ton log on most terain and more on flat land less on extreme terain.
Take the truck for the big logs.

The biggest logs it was designed to carry are 12 ft x 24" ash which run around 1800 lbs each according to the weight calculator. But most of them will be under 20" and 10'-6" long so it should be fine. I only have toy sized equipment compared to most on here but am having just as much fun.

This morning I went in my shop and found walnuts on the tool boxes, on tools, and benches. I started looking around found a half roll of paper towels shredded and items knocked off shelves. Then from the corner of my eye got a glimpse of a very large chipmunk running across the floor. It must have moved in last night to get out of the rain. It disappeared but I don't know where it went. Set the have-a-heart trap and hopefully will catch it tonight. Did get a little more done on the arch. I got the front lift latch figured out and made a couple of the parts.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1034.JPG)
Got the catches cut and pivot shaft started


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1031.JPG)
Got the latch holes drilled through the vertical member. Have to go out to get a spring, make some bushings, and a handle. It allows the front lift to be locked up for travel or when you want to pick up a short log with just the claw. It automatically locks when the lift goes up.

Still trying to find tires so I can try it out, but no luck yet. I have found every size 16, 17,&18 inch but no one has any good used 15 inchers. Got to work on it a little today, finishing up some of the loose ends.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1036.JPG)
Cutout and beat a piece of 12 gauge over a pipe to get it round to fill in the top of the tongue.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1037.JPG)
Finished the front lift lock, added a spring, bushings,  stop, and release lever.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1039.JPG)
Cut a brace for the claw support arms


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1040.JPG)
Got the brace welded in


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1041.JPG)
Made a spring loaded lock to keep the LOGRITE from being able to bounce out per Ray's suggestion. Hopefully soon it will be time to finish grinding welds, sandblasting, priming, and painting. Never caught the chipmunk, it disappeared on its own.

Bob if you do any kind of metalworking a plasma cutter with a hand torch and drag tip will allow you to easily cut shapes without CNC and is a good timesaver for fabricating parts that is simple to use and a good place to start.

   Really nice build, our tire guy in town sells tons of used tires I needed a 15 inch the other day. He told me I was lucky he had one, he said out of loads of 200 plus tires there will only be 2 or 3 15 inch. He said within 6 months or so he will be surprised if there are any.
                                                               Tim
Same problem here, any 15 inch tires I find are basically junk.

I made a small trailer out of a rear end of some minivan. I wonder if that had 15 inch tires. With my luck it does.

Today I pulled it outside to take some pics. Still missing some covers, the box for chains, 1tire is 3 inches bigger then the other so it sits crocked, and it is paintless, but that will all be fixed soon. Tomorrow I will try it out if I get a chance.

If you look at the claw you can see the bars that have been added to keep it open when lowering it and then when they contact the log it automatically closes and clamps the log.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1101.JPG)
I added a ash back bumper, above it a slow moving triangle slips in place. The lights will be moved for more visibility in the future


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1102.JPG)
The front jaws will have springs added that I am waiting for and automatically close under the log when it is lowered.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1103.JPG)
Hopefully tomorrow I will post some pics of loading a log.

Today I finally got to try it out and everything went great. Took about 30 seconds from the time I got off the tractor to load a log. Not one bit of effort required.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1107.JPG)
It was easy to maneuver in the woods. Cut a log that was 18 in large diameter, 16 in small diameter and 12 ft 6 in long. There will be no problem with up to a 24 incher.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1109.JPG)
Backed over the log in a pretty tight spot.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1111.JPG)
Pressed the button on the winch remote to drop the claw and front loader. The claw locked around the log and I had to kick in the front lift teeth


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1112.JPG)
The claw auto lock worked great


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1113.JPG)
Pressed the remote retract button and the front lift went up and locked in place.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1114.JPG)
Then the rear of the log raised into place. The winch worked great and didn't even slow down. The entire lift process took 10 seconds.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1118.JPG)
Was easily able to maneuver around tight places. The log was stable and did not move.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1121.JPG)
Everything worked perfect, no flex or twisting I am extremely happy with the results. The log will be sawn into tomato stakes tomorrow.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1131.JPG)
Done playing back to finishing up splitting my last pile of firewood on my homebuilt splitter. The arch will now be disassembled, sandblasted, primed, and painted ( some small parts powder coated ).

Thanks for all the kind comments and sticking with me throughout the build. It has been a fun build and with a couple of changes to the front lift I should be able to load a log without leaving the tractor seat. The only prep required is to roll the front of the log on a block so it is not buried in the mud. Just to see how long the little battery would last I dropped and raised the log with the winch 25 times  and saw no difference in the winch speed, but after painting I may add a solar trickle charger to keep it topped off. I will post final pictures after painting. Thinking of my next project already.  ;D

Remember a while back I mentioned a chipmunk in my shop that I thought had moved out. Well last night I backed the arch into my shop with the log still hanging from the winch to see if the brake would hold the load overnight. Well this morning I found 2 walnuts that were eaten on top of the log.

Garden is planted and the lawn is under control so I got a chance to work on the arch again. All the claw parts were sandblasted and finished. The black parts were powder coated but the jaws were to big to fit in my oven so they had to be painted. All the UHMW washers are fabricated.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1244.JPG)

Thanks Ga Mtn Man. I just meant that there were several parts stacked up in some locations that  the tightness of the nut controlled how easily the jaws would open and close or to tight and they would not move at all. So I tightened the nuts and then backed them off slightly so there was a slight amount of pressure on each joint ( I called preload ) and then tightened the soft tip set screws to lock the nuts in that location. It just allowed me to make it a smooth operating assembly that would stay that way and not need adjusting over time.

They are steel with a nylon tip. But the nylon gets chewed up and they don't really lock good until the steel part contacts the stainless bolt.

Yes they would, but I already had the 3/4" Hi strength stainless steel bolts, nuts, and the set screws so that is what I used. Lock nuts probably would have been $5.00 each and added $50.00 to the arch with shipping and tax.

Been a long time, but got a chance to work on it again, so I have a couple of new pics


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1406.JPG)
All the parts for the front lift are finished.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1409.JPG)
Tried torsion springs to move the jaws into position and hold them there, but it was dangerous so I wound up cutting the ends off some 3/8 extensions and welding them to the pivot shafts.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1412.JPG)
Then there are palm ratchets that will snap in and control the direction and location of the jaws.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1411.JPG)
The front lift is assembled. Just waiting for I more palm ratchet to finish it up.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1407.JPG)
Had old tractor supply  alkyd paint I was going to use, but that stuff is not UV resistant and fades quick so I decided to try the Deere paint that is a synthetic acrylic enamel and the same paint used at the factory which has good fade resistance.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1404.JPG)
Found some new wheels on clearance at TSC for $12.00 each and they are now painted JD yellow. Nice looking cant hook now also. The Deere paint goes on great and is extremely glossy. I picked up a HVLP gun from Harbor Freight and was surprised how there was basically no overspray once I got all the settings right.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1415.JPG)
The main sections of the arch are finished welding, ground, sandblasted, and coated with rust resistant primer. When I get a couple of low humidity days they will be sealed with JD buff primer sealer, painted green, and assembled.

Thanks mad Murdock and Larry. Got some primer / sealer on the bottom sides of the main parts today and I must say I love how that John Deere paint goes on, covers well, and tacks up in about 15 minutes. The biggest issues are waiting 36 hours before recoating ( but by then it is quite hard and can be sanded without gumming up the paper ) and regular paint thinner will not clean the gun you have to use the expensive Deere thinner. I will never buy the cheep stuff again.

That's going to be top drawer. I've used some of the JD paint in the past. Was easy to use.  I just don't think I can get the courage up to use Green. Haven't really decided on a color for the swing saw yet.

Good job 21.

Got the John Deere primer/sealer applied. It is like a caterpillar yellow. Had to make some stands for the final coat, tomorrow it will all be green after a final wet sanding.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1421.JPG)
It is amazing how the finishing process takes more time then the build. I am spraying this outside because my shop stinks from the primer/thinner even with the HVLP gun making basically no overspray.

Carry on
After backing over the log it takes about 10 seconds to drop the front lift and claw. The claw locks on the log and you just have to kick the front lift jaws under the log which takes about 5 seconds then push the remote up button and about 10 more seconds which raises the claw and front lift at the same time with the log and locks it in place, then jump on the tractor and takeoff. When it is done I will post a video. The remote for the winch works from 25 feet away and I eventually want to automate the front lift jaws swinging under the log so you won't even have to get off the tractor to load.

Well the arch is finally all painted and back together. Never found good used tires for a reasonable price so I just ordered some new ones. I decided to go with new Goodyear Wrangler truck tires instead of trailer tires. I am hoping the small lugs will keep them from slipping sideways on muddy hills and they are 3" larger diameter then the trailer tires with a higher load rating. They should be delivered on the 29th and after I mount them I will post some final pictures. I should change the title to " I turned building a simple log arch into a career because it took so long". So Gadrock you may have to change your pants as it will be another week. :)
Title: Re: The start of another log arch build
Post by: 21incher on July 25, 2014, 03:35:56 PM
The tires came a week early so I mounted them and finished up a couple of other loose ends.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1490.JPG)
The tires give a much more rugged look over the trailer tires and 1 1/2 inches more ground clearance.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1487.JPG)
Made a cover for the battery terminals that contains switches and wiring to turn on the tail lights and flashers using the onboard battery when it is hooked up to a vehicle without a trailer harness like my compact tractor.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1488.JPG)
Mounted the plastic ammo box to hold the (2) 7 1/2 ft long 3/8 safety chains for highway use or short logs.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1484.JPG)
Machined the white UHMW blocks to lock the claw in place and keep it from moving with a empty arch.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1492.JPG)
Got the logrite lock back together.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1491.JPG)
Welded a scissors jack to the short hitch and made a small crank handle for it. Only 1 more small  item to finish up after Harbor freight gets in the last palm ratchet I am waiting for to finish the front lift lock. Then I will pull it out and get some final pic's.

I made the label because every time I make something and paint it Deere colors I usually place a Deere sticker on it and people think I bought it from John Deere, so this time I decided to personalize it. The 2412 means it is for a max 24 inch diameter x 12 foot long log (some day there may be a 3616), and the made by name is what my wife calls everything I build so I decided to use that to let everyone know it has nothing to do with Deere.

I was thinking all the JD guys are going to be bugging you, where did you get that. Great craftmanship, you do good work, very impressive, I have enjoyed watching the fab. that plasma cutter is really awesome and your machining and welding look topnotch.

Thanks again everyone. I just found out that when finishing it up I slowed it down. The winch came with 50 ft of cable and when finishing everything I decided to cutoff the 30 feet I did not need without thinking :embarassed:. This removed about 3 layers from the drum which in turn caused the time it takes to drop and raise the claw from 10 seconds to over 14 seconds. So much for my 30 second lift time. >:( Just set myself up on YouTube and will try to make a video in the future.

Too much unused cable on a winch is a pita.  With your skill, I suspect that you will increase the drum size on the winch.

Agree with increasing the drum size... maybe some plastic pipe cut to length and with a side cut that will will snap over the drum. Then a larger one over that...  have used this idea to make spacers that snap on and off for adjusting the forks on my FEL.  Make the side cut wide enough to get the spacer to snap over and not fall off.

I have decided to live with it for now and in the future will most likely replace the cable with a larger diameter cable that is slightly longer because I feel the Chinese cable is undersize anyway. The winch relies on the friction of the first half dozen wraps against the drum to keep the cable from pulling off so any slippage from a spacer could be trouble.

Thanks again everyone.  After seeing many other arch builds before starting this I realized the biggest problems were trying to move the log out of tight places with it swinging side to side and not being able to secure the front of the log for traveling down a bumpy road. The front lift solved these problems for me and is basically the only difference between this and any other arch out there. My lift got a little complicated because I used materials I had on hand and am lazy so I wanted to automate it, but a very simple hand operated version of the idea could easily added to any arch out there. I can't wait to mill some logs that don't have mud and rocks ground into them from dragging out of the woods on the ground behind my tractor. The savings in blades alone should pay for the arch.

No video yet. I wait until the leaves fall to start pulling out logs so that is when I will make one. With all the rain it is to muddy to get into the lower part of my property now anyway. I set up a YouTube account and have to figure out which video format to set my camera for and find a place to upload it because I only have a metered 3g connection. Right now I am spending most of my time canning, making sauce, and pickling so I haven't even looked at it in 2 weeks. I did finally get the palm ratchets so it is 100% complete. I also have to get the mill trailer I built last fall sandblasted, primed and painted before I get started because the wet sawdust rusts everything. :)

I would like to add a warning to anyone using one of the low cost Chinese winches on anything. Add a disconnect between the battery and control box as they can turn themselves on.
I went out in my shop this morning and found this


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1721.JPG)
The claw laying on the ground


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1720.JPG)
and the winch cable snapped with a dead battery. It seems that the winch turned itself on stuck in the retract position and snapped the cable (which is to light for the winch), Then continued to run until the battery died. No one has been in the shop the past 3 days and that is when it happened. We had some terrible lightening storms during that period and I am wondering if that may have triggered the remote control circuit. I will now be adding a disconnect to the winch control box power wire as I don't trust it any more and a heavier cable. I charged the battery some and the winch remote functioned properly. This proves that you get what you pay for.

No other problems, and it would have to be a pretty smart ghost to hold down the on button on the remote to turn on the winch and then hold down the retract button until the battery died. I think it must be a defective Chinese made product that was falsely triggered and went haywire. If only the cable were heavier it would have blown the circuit breaker and shut down.

I think it is the other way around, the door goes up and the log goes down ;D

After looking it up the working strength of the cable that came on the winch is only 560 lbs with a breaking strength of 2800 lbs with a 2500 lb pull rating of the winch. Which actually means it was not safe to use on the winch anyway and could be a dangerous combination if you were standing there when it broke. The winch turning on may have been a message from above to warn me. Going to have to enlarge all the grooves in the pulleys to install a larger cable. Looks like I should have spent the extra money on a brand name winch upfront.

I went with a friend to pull out another friends tractor off the back side of a pond dam.  He had a 12,000 pound Champion (Chinese of course) winch on the front of the truck.  It was an easy pull getting the tractor out and he was reeling in the cable when the contactor stuck in the run mode.  The winch kept running until it caught on roller fairlead.  Tripped the breaker.  If it had happened when the tractor was on we would have pulled the tractor over the dam and into the pond before we could disconnect the battery.

All in the life of a old fart. :D

Finally got around to fixing everything today. Something randomly triggers the RF receiver and I can't find out what it is. I think it must be defective. Replaced the cable with the next size up that is rated for 4000 lbs. Had to open up the grooves in all the pulleys to fit it in.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1818.JPG)
I also placed a disconnect on the winch power so it doesn't happen again.


 (https://forestryforum.com/gallery/albums/userpics/34694/IMG_1817.JPG)
And I also added a small solar panel to the top of the chain box that should help keep the battery charged. Now it is a little greener.

If God would have contacted 21incher and instructed him to build an ark, the animals would have sailed to safety in a top notch pimped out ocean liner instead of a rather unattractive, single colored wood dingy :D

Thanks Busy Beaver.  It is nice not having to struggle with cranks and chains. I realized today I have to automate the front lift arms so I don't have to bend over and turn them in. Then I will be able to remain in the tractor seat during the lift. If anything should happen to me I am sure my wife would sell it to you for the $100.00 I told her it cost. I think the 36 inch one is going on the backburner as I want to build a small CNC router next.

Originally I bought 2 torsion springs and was going to have a lever that tripped them when the front lift hit the ground, but when I mocked it up  it seemed dangerous as the arms swung in quite violently so I changed it and now realize I should have put more thought into the solution. Luckily it still functions great with a little bending and I have a couple of ideas to try this winter. My sketches for a 36" one are exactly as you describe with 2 claws for the lift, but that one will weigh close to 1000 lbs. empty and have mechanical locks on the claws.

Well put it to work today. Some paint is missing and it is covered with mud but it easily got the job done. Have to drag out the mill and get busy milling some ash into paneling, and walnut for a dining room table. Wound up using the Kubota to pull it because it is lighter and does not sink into the mud like the Deere :)

I had to do just that with 1 of the logs where the wheels would not fit between a couple of stumps, but I didn't want to pull on the claw so I lifted the end of the log with the claw, then wrapped a chain around it and hooked the chain into the anchor slots. I then let the claw down to tighten the chain around the log and pulled it forward with no problem and then was able to load the log normally after dropping it back on the ground. So it looks like it will be able to skid long logs also in a pinch. :)

My next project to build after my mill will be a log arch.
Being that most of my logs will be coming off a steep hillside I want to make the tongue of the arch
so that it slided in as I brake the tractor. As the tongue slides it will activate brakes on the arch.
It will also have a latch to stop the slide so I can back up with out it brakeing...

I think using stub axles with brake flanges and electric brakes would be the easiest solution. Just get a old brake controller and mount it on the tow vehicle and manually control it. Moving parts and mud can cause problems. I found my biggest problem came going up a muddy hill when the three driving wheels of my tractor lost traction and everything slid backwards out of control close to 100 feet before being able to stop it.
The arch is in the latest issue of Farm Show Magazine that I received yesterday.  :)

Thanks the cfarm. I try to push the idea of how nice it is to have something in the front of a small arch to  fix the front of a log to. I think it makes a big difference to keep the log centered  and be able to maintain the center of gravity on a side hill. Plus it can take some of the stress off a lighter weight frame.  :)

Has anyone ever made just an axle that you would put under one end of a log and then pick up the other end of the log with the 3 point on a tractor and then be able to pull the log that way?  That's what I'm dreaming up to bring big logs out of the woods.

   I had a rear dolly built and use it in conjunction with my log arch. The arch holds up the front end of the log. I don't see why something like this could not be used with a tractor to pick up the front and tow it within the limits of the tractor and terrain.


 (https://forestryforum.com/gallery/albums/userpics/38064/QN5A4704.jpg?easyrotate_cache=1510718601)
See dolly on left on the ground.


 (https://forestryforum.com/gallery/albums/userpics/38064/QN5A4711~0.jpg?easyrotate_cache=1510718647)
I lift the log with the winch on the log arch (You could use your tractor) set the log in the Vee and strap it in place with a ratchet strap.


 (https://forestryforum.com/gallery/albums/userpics/38064/QN5A4717.jpg?easyrotate_cache=1510718745)
I then hook the front of the log to my arch and tow it to my log yard - I see no reason you could not do this with your tractor if within its limits.

Has anyone ever made just an axle that you would put under one end of a log and then pick up the other end of the log with the 3 point on a tractor and then be able to pull the log that way?  That's what I'm dreaming up to bring big logs out of the woods.
That makes for a pretty big turning radius in the woods. I kept mine as short as possible to track behind the tractor in my tight trails. It will go anywhere the tractor can fit.

I can only handle about10' at the most on my mill,so I wouldn't be towing anything longer than that out of my woods.  I think it will work great for my needs.  Pickup back with loader and slide wheels under.  Then pick up other end with 3 point and tow to my mill.  I don't want to be trying to carry big logs long distances with the loader.  This gives me some ideas.  Thanks.

I'm a new member, and I read this string after seeing a reference to it in another. 21incher, that is one of the most innovative and professional Fab jobs I have seen. Great job.
Just another one of many things I'm learning by being on this forum. Thanks for walking us through the thought process and build of this handy Log Arch!

Thanks olcowhand and welcome to the Forestry Forum. That is what happens when you have too much time on your hands.  You will find unlimited reference info on here and I am sure you will be contributing info and ideas in the future also.  :)

I just picked up a Strongway ATV arch rated for 1000lb and I'm hoping it pans out.  This is the kind of thing I would fab myself but get it 95% done in a week and finish the last 5% over the next year.  I'm hoping it doesn't let me down but it seems every time I buy something, the deficiencies show up pretty quick.  This looks like it will work well behind my Honda Rancher, if I had a bigger, more powerful UTV, I think I'd want something more robust.  Anyone have any experience with a Strongway log arch?

I have a Strongway 1000lb arch that I pull with a Polaris Sportsman 550 and it works great.  However it came with no instructions on how to use it.  I have found that it is best to use the winch to raise the log then wrap the chain once around it, then lower the winch so the log weight is carried by the chain.  The log tends to swing around more if you carry the weight on the winch strap.  Sometimes I use a Logrite Junior arch as a rear set of wheels to keep the log entirely off the ground.
