Too bad the power thing isn't going well, leaks and such. If starting with smallish pieces, I may have something to offer as a working alternative, inspired (sort of) by this

I'm still getting the first real working stove together (working as in made outa refractory, metal can't take the heat). I've found that splitting the wood down to small enough pieces seems to be incredibly time consuming. If only I had a way to hold the axe, and make it hit the same point every swing...
Here's what I assembled outa scrap, a tie strap and a cheap axe from Harbor Freight (see, they can be helpful). The vertical stop helps hold the piece whilst keeping fingers away from harm, flat piece stops the blade if it gets that far.
I cut up a skid's worth of flats in about ten minutes; hit it in the right place and the nails just fall away. Swat it with the small sledge if the piece is too thick. Works fairly well, but then again, I don't have much frame of reference; I'm just getting started with all this. Slide hammer thing works well, especially with that big sledge head
