I have tried ax. Not a pretty sight. Wedges take me hours to do one. I'm surprised you have electric. Guess you could hook to generator.
So you don't know anything about the hydrolic manual type?
some people's woodpile ops is in back of the garage - electric is readily available - electric chainsaw & splitter and floodlites for nite work - no engines to mess with and cheaper $$$
only trouble with the commercial made electric splitters is the size/hp - not going to find anything into bigger tonnage ram capacity ....
