I've experimented with Black Locust, Elm and Hazel so far. I've had bad luck with B. Locust as it developed those annoying compression cracks on the belly. These kind of cracks are so frustrating. I put so much time and energy into making a bow only to hear that ominous sound of wood cracking while tillering. I take it off the tillering board and I see the compression cracks, which I know will eventually lead to bow breakage. This has mainly happened when working with B. Locust. I'm feeling so disappointed with B. Locust because of that. BTW, the width of my B. Locust staves have only been 2" wide.
Hazel, however behaved very well for me when tillering or even heat treating. I'm just not sure about long term performance of Hazel bows.
What are your experiences with Hazel and B. Locust
Thanks
