I recently built my Bro a woodsplitter, we wanted electric for the power, reliability, no gas, no gas fumes, less noise etc.
It pretty much is going to be stationary in his yard, he has tree services bring him the big wood for free rather than them hauling it to the landfill and getting charged. Some are oak, pine and eucalyptus up to 4ft diameter.
Found a good used Baldor 7.5hp Industrial, 3450 motor, a new Prince 6x30 cylinder and got to work.
Used a 8x48 wide flange beam and a lot of 1" plate.
Haldex 22gpm pump.
1st thing I decided is I was going to offset the beam from the axle and tongue. It didn't make a lot of sense to me to have the beam centered and doing so a longer lift/staging table could be used. Hence the name and the eye.
The tongue is pinned for quick removal.
^Finished , and folded up for transportation.
^Lift/staging table out.
^Lift/staging table down.
^Lift arm is separate from lift table for folding and to not allow the table to raise the splitter when it contacts the ground. Same axis of rotation.
^And on bronze bushings with grease fittings.
^4 way.
^Both the lift and 4 way have needle valve to regulate the speed.
^I put the controls so they would be the most intuitive. As in farthest from operator is lift, middle, 4 way, closest splitter, and orientated them so when you want the lift/4 way to go up you raise up the handle.
^I temporarily attached the whole thing to an axis, supported on 2 heavy steel sawhorses so I could rotate it all and make purty flat welds. Rather than my drippy out of position specials.
Ugh, photo posted out.
I will show some construction pics if interested.
Oh and it works great. No hardwood where I live and build it, only softwoods. Worst I could find was some 24" nasty pine but it only required 500psi to split. The PR valve is set at 2500psi and detent at 2000psi. So the pine wasn't much of a challenge.
