I've been splitting wood with a splitting maul, wedges and a ten pound sledgehammer. That's worked pretty well except when a piece of the maul the size of a .38 bullet split off and buried it 4" deep in my thigh. It's still there ---- I'm lucky it didn't hit something more sensitive. I have an 80 pound pneumatic jackhammer usually used for breaking up concrete streets. I'm wondering if anyone has used that kind of equipment to split wood. It applies about 40-50 horsepower or so when using 60 cubic feet of air @ 90PSI per minute. At present I just have a pointed gad used for breaking concrete, but something more appropriate for splitting wood could either be purchased or forged without too much trouble, I imagine. I suppose I should just give it a try and see what happens. I also have a smaller clay spade used in place of a pick for breaking up clay and dirt. That's a lot lighter and less powerful, but still probably puts out 20 HP or so. The shovel like tool on the end of that could be sharpened up for splitting wood with a little forging I would bet. Has anyone heard of using this kind of equipment for splitting wood?
