I scored a standing dead elm from one of the yards at work, I got it home, it's cut, but I can't seem to get a good split on any size piece. I have an old maul that kicks azz on a load of maple I also got this week but I look like a fool trying to split the elm...any tips, suggestions? It sounds like a baseball bat when hit against itself so I think it's been deceased for a while but if I keep hitting this stuff with no results, I'll be deceased.
