IMG_6808.JPG IMG_6810.JPG IMG_6809.JPG IMG_6811.JPG IMG_6812.JPG not to bad today as I was able to set the frame onto the lower portion of the "put together" to make it a whole unit( I guess that is what you might call my cobbled junk). bolted, welded where needed to hold everything in place till I get a chance to test the "farmer, logger, junk maker project to use pulling a few logs out of the wild Midwest forest. anyways here's the proof in the "put together" as it is so far.... still no tongue for the hookup yet.
 
look's like tomorrow, so I can see where it's weakest point will be?? thinking I might need to add tire chains to stop the side ways sliding when winching at an angle......any thoughts jim from your eye's ? I will get it out in to the light for a few bright pic.s!

Looks good. I think the first place its going to break is the section of tube to the hitch. It just looks a lot smaller than the rest of the build. Nice job.
?? "WELL" marshy, you win the prize for the right guess!! hooked up to the first log and started the retrieve and the tongue buckled up with a loud "SNAP"... that's all for today after 15 minutes of logging! back to the three point for the rest of the day ... still managed to get out 11 nice logs at 16'.4" to salvage the test run so I don't feel to bad. the weak spot wasn't hard to0 see but what do you do? just keep trying like the steer hey!
 
need to add an extra axel to the rear to support the leverage of the a frame. a shorter tongue of 12" max/drop pin with an added cross member of 3x3x3/16 behind the tongue to square the main frame. same for the extended rear frame for the added axel with a log cradle to rest the log/s to take the pressure off the winch line during the skid. another couple hundred bucks should do it.IMG_6817.JPG IMG_6825.JPG

or something heavier than a 2" x 11 gauge square tube for a tongue...3"-4" x 1/4" wall square tube will work, I would keep it long otherwise it will want to lift the tow vehicle a lot easier
 
picked up another 3/4 ton ford rear end to make the "put together" a tandem axel to support the weight of the logs when winching. start building again when I get time next week. the price of new imported heavy steel sure don't stop climbing for nothing!
 
I'm still concerned by that tongue. It's a long lever on the other end of the long boom, with the axle as a fulcrum. Tandems without a suspension will help with that, but will make tugging over uneven ground more difficult. You want larger geometry and thicker walls on the tongue to be supporting that much weight.

Put the second axle behind the first under the boom and you can use the tube to hold your hitches up, and it will help take weight off the tongue.
 
How long from the hitch to the first axle, and from the tongue to the triangulation at the front of the frame?
 
need to pick up the steel in the morning after I change the alternator in the pickup. then get time to strip the guts out of the other 3/4 ton axel .. with the cold temps this is good garage working time for the "put together project" jim! beats working out in the cold for sure...

with the hitch going to be a drop pin the extension will be a foot forward of the "A" and to the axel center it should be close to 5 feet.... with the addition of the second axel the diff will be an added 5 feet to the rear where it will be coupled. so the boom as it sets will extend about 12" to 18" behind the log rest!
 
You might want to shorten up the axle center to center distance. I know you've got some rubber to clear and should have a little daylight between 'em, but the longer the wheelbase of your puller, the harder it's going to be to turn when it's got a load on it.
 
That should be reasonably good towing, but gonna be a female pooch to back up. Longer tongue backs easier.

Have you considered a telescopic tongue?
 
Nice work. It sucks when homemade projects fail in trial runs, been there done that. Have you considered a piece of "I" beam to run full length of the machine and tie the hitch to that. Way less prone to bending or snapping than square tubing. If you were close I could get you a piece, but I'm sure UPS would want the price of a new truck to ship 6' of it. Can you get ahold of any old railroad track?
