I had the bright idea to build this thing after using the truck to pull some logs off a pile then having to bend over to cut them to firewood lengths. I have a dump trailer I built a couple of years back and I'm going to put this on the tongue. I will do away with the electric over hydraulic unit on the dump trailer and power the grapple and dump with a gas powered motor hooked to a hydraulic pump. I have most of what I need here, I have a bunch of 2"x2"X1/4" angle iron I picked up cheap at the scrapyard this summer, the main lift cylinder which was given to me, the pump came in a hydraulic tank I used for my log splitter, a piece of 6" well casing that was given to me, 3/8" x 6" flat stock was left over from a previous project, I bought the 2 1/2" square tube for the boom, I had the jeep axle and the bearings were in a drawer that I had bought for a project that never happened.
Anyway, the plan is to get a HF 6.5 hp motor for 99 bucks, a backhoe control valve either used or new. I will need to buy a crowd arm cylinder and sabilizer cylinders, an adapter for the pump to motor and hoses etc. etc.
Here are a few pics of what is completed so far, I will get some more pics of the bearing set up for the base of the turret.
Here's how most of my projects start, a doodle. I doodle when I have my morning coffee! LOL





Plan is to weld the spiders, put a large chain sprocket on the yoke and drive it with a hydraulic motor, I'm trying to figure out the gear ratio and how fast the turret will spin. Given a 6:1 chain drive and a 3.73:1 axle drive I'm guessing somewhere around 24:1, I hope this will be slow enough. (I could use some help here)
I'm searching for the drive motor.
I will keep you updated as this thing progresses.
thoughts on stabilizer legs, folding or sliding, I'm thinking folding will be less weight?
