So, I had a dream last night (I know, I am not :censored: right in the head) about this concept. I was thinking, a better way to do this, is this: Rather than mount the wedge on the ram, have the wedge stationary on a platform or the like (see pic)
Have a set of rails, in which an impact plate is mounted, like railcar on tracks. Place the blockwood (round) between the impact plate and the wedge, and use the kinetic energy of the ram to force the impact plate into the blockwood, and force the blockwood through the wedge.
I dont know why I am thinking about this stuff in the middle of the night...
I Like this thing! Maybe you could rent the guys from the Capital One card advertisements to swing the ram. Or power it like a spud drill with a Mad Max type car. Heck just mount the ram on a Mad Max car and go for it.
Or you just rent the splitter.
Wait, how about powering The Thing like a diesel pile driver? That could work.
