I think it looks like his log splitter :-/

If you want to crush perfectly good blocks ( if you're talking
about concrete blocks), then use this. It is a log splitter.

I saw block splitters that worked on the same principle, and worked good.
I'll test a couple tomorrow, and let you know. You never know unless you
try. Unless you know it all beforehand anyway. I'm one of the people who
don't know it all.

IF your block splitter fails to work as you desire or expect, consider
making the contact points out of large (2"+) diameter steel round
stock

I have seen professional models that cleave cleanly. One seems to have two
hinged plates at the bottom that would give just a tiny bit to encourage the
block to split in the middle. The other may have something of a convex or
concave base, but it does not show it close enough to tell.

I'm going to try the first suggestion of using a couple of 2 x 4's to get a
little space between, or maybe make the board under slightly tapered.

I do think I will have to grind off the lip where the blade will contact the
block.

It's rainy outside, and looking very much like snow is coming. Will get to
it when I get to it, but it's nice to kick around ideas first.

Thanks for the help, fellows.

BTW, it splits logs pretty good, too. g
