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 basic arch frame.


 
Another view of the start of the frame


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


 
Rear view. The tongue is a old 3" x 4" tongue from a boat trailer


 
Plasma cutting the front supports


 
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.

I will be following this thread.  Nice plasma cuts!

Wish I had a plasma cutter!  Is it numerically controlled?  Those keyhole slots are sweet!  Need to see the overall in a pic when you get there.

Nice!

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

Thanks everyone. It is always fun to start a new build after a long winter.

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.

Kind of like your CNC router. If you can draw it you can make it. What used to take hours only takes minutes.

I just thought I was impressed with those banjo holes... really impressed with you building the CNC. ;D

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


 
Designed and plasma cut the claws.


 
They wound up being pretty beefy because I only had 1/4 plate. Wish I had some 1/2 inch.


 
That is a 16 inch diameter plate, the jaws are designed to handle a 24 inch diameter log weighing 1500 lbs.


 
This is where the assembly will mount when done.


 
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.


 
Starting to look like a big claw.


 
Claw in closed position


 
Pivot plates for the jaws cut.


 
Lifting links plasma cut.


 
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.


 
Top pulley brackets


 
Made some spacers and welded the asm together.


 
Next I have to make the idler pulley for the cable to raise and lower the claw.


 
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.


 
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.
