A friend is having a 4' diameter walnut tree taken down and hauled away. ($1,200!!) She asked if I wanted any of it. As it happens, I just got a bandsaw and have been playing with cutting firewood into lumber. Trying it on her tree should be fun. But how practical is it? I have split plenty of firewood, but never anything this massive. Is it even possible to split a 4' diameter (by what, 3' or 4' long?) section with a maul and a couple wedges? Or should I settle for some large branches, or will they be mostly sapwood?
Anything special to look for, as long as I have the whole tree to chose from? I know crotches are desirable, but they are also just about impossible to split.
She is not having the stump ground out because it is too expensive. I have heard that is the most valuable part; is it worth trying to sell? I suppose the tree service would do that if it were practical.
(I have more firewood than I can use, so I don't need any for that...)
