I have an opportunity to buy a large number of seasoned burls; cedar, maple, pine, hemlock etc. from a few inches to a few feet in diameter. Apparently they are 'well' seasoned. As we all know, burls are not that easy to come by and I'm inclined to stock up but...I'm not that knowledgeable about burls and I don't want to wind up with a lot of old fire wood. I don't have a fireplace. I know big cracks and soft areas aren't good. What could be involved in preparing the burl to turn? Any advice would be appreciated.
