OK, I’m going to ask the silly question, why only one ‘splitter edge’? I’ve only used the hand tool 6# maul.
Is it reasonable to build a kinetic splitter with splitting edges one on each end, one stationary, one active? Round wood cutoffs mostly like to split along the wood grain, or perpendicular to it, and I was thinking maybe the pinion load required to split, would be reduced nearly by half if splitting from each end. I’m guessing when the hard knots hang on the active, or the stationary splitting edge, the alternate splitting edge will attempt to push on thru anyway from it’s directon, the kinetic energy at full force would be used when either of the splitting edges are hung in the wood. (oops! my pix doesn’t show the active end of the ram or rack being well connected as in reality, it must be connected to the beam, to prevent bucking, rack misalignment, etc.)
