I wish I knew the answer to that Gary, but I've only made bows from Osage. I'm sure somebody here has done it and I did see a post somewhere about black cherry that turned out real nice.
I would do a search for it on Trad gang and see what posts turn up.
Just use the search engine up top by where it says "My Profile" and the "Search" feature is just to the right of it.
Hope that helps.
