Yeah Ed, I understand what you mean, I have a large walnut in the north yard. When she finally comes down, I'll being saving some of the wood for bow projects, and other!
Black locust or Honey locust can be used for bows. And even if not for a self or backed bow, you could have sawed for laminations. That is if the wood is sound. You could even save, good short pieces for handles, tips, etc. It's all Good!
Hope you get some good stuff from her!
Good shootin,
Steve
