I built this from scrapyard salvage
5hp electric motor 3400rpm, 4.5x28 ram (I think off a CAT?), 13 gpm pump, airport luggage mule tires,hubs, spindles. Solid rubber tires, won't be getting a flat.
Reservoir is a piece of tube steel. I wanted it narrow enough to roll through a 3 foot doorway,,,, and tall don't want to be bent over a midget splitter.
There is a 30" space between the wedge and moving plate even though the ram travel is only 28". I like this because the split wood hangs there without falling off and I can pull it back and resplit it, or just toss the next piece in behind it and keep-a-going.
Used the detent type valve. Detent lock in forward or reverse and the automatically drops back to neutral and either end of the stroke so I don't have to keep my hand on the lever.
I love electric!
Quieter, no gas, no starting issues, no fumes and no one asks to borrow it!
2.5 gas hp is about equal to 1 hp electric. So that is about the same as a 12.5 gas motor.
I split about 6 cords a year, it works great.
What is the bore and stroke of your parts and pieces?
