I have a question about milling root balls and potentially burls. One of my neighbors might be getting ready to lose a silver maple in their front yard and the tree was planted in about a three foot tall raised bed. You can see that by now it is almost just the root system in the bed and probably very little if any soil. The tree itself is nothing spectacular and sorry I don't have any pictures. I was wondering if anyone had and luck with silver maple root balls getting figured grain and maybe burls. The idea I had was to remove the retaining wall and either air spade or power wash as much soil off and then mill it. Ideally the whole thing would be above ground and I could get some good crosscut slabs out of it with a lot of work. Any ideas or experience will help. Still consider myself on the a lot to learn end of milling.
