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 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.
 

 
Welded them in place
 

 
Making the ball bearing cable pulleys next and then a couple more braces.

Looking good, real good, wonder what color this one will be?  ;D
only have a few chain saws I'm not suppose to use, but will at times, one dog Dolly, pretty good dog, just not sure what for yet,  working on getting the gardening back in order, and kinda thinking on maybe a small bbq bizz,  thinking about it,

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.

Turned the heads off the bolts and welded them in place so they don't back out later.

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.  ;)

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.

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  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.

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 )
 

 
The 2 brackets plasma cut and bent.
 

 
Welded them in place
 

 
They also keep the claw from swinging during travel. Also got the last cable pulley turned.

I guess when you take longer than two days to build something, you have time to think and get it right.  That will be a cat's meow.     ;D

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.

Thank You.  Necessity is the Mother of invention.  (old saying)   ;D

I am anxious to get my winch installed.  Problem is that the arch is at the tree farm and I am not.   :-\

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. Like my wife tells me I could go out and buy the item or I could build it for twice the cost. It is a fun small project for my spare time that keeps me out of her hair.

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.
 

 
Axle plates
 

 
Welded them on the arch legs
 

 
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.
