I successfully split up the smaller stuff of the Poplar tree I had taken down a few months back. Now what I've got left is the really big stump section. The thing is 26" across, a very big puppy. I used an 8' maul for the thinner stuff, but am not sure how to proceed with the fat ones. Can I get away with working at them by splitting off outer sections until I get into the middle? I remember someone mentioning using wedges, but am unsure of what various types and sizes are available. I'm pretty accurate with the maul, but not the strongest chick on the block. I asked the guys who cut up the tree to cut the big pieces in 12" sections, but of course some of them are considerably longer. Any help on how to tackle these would be welcome.
