My neighbor has 8 trees dead or mostly dead coming down. One is a Shingle Oak about 24" in diameter. I couldn't find anything referencing turning this wood.
Other trees are several Shagbark Hickory 24"+ in diameter that I don't want any part of because it is so hard and cracks, a small pin oak 14" in diameter, and a cherry 30"+ in diameter that I will get a lot of.
