Mark you and selfbowman may have some thing. I have another stave floor tillered ,and straightened on a 4 inch reflex form. The wood is at 12 percent, and wide enough to make what I want. The reason I asked the question is that this wood seems to fret if I look at it wrong. Unlike the blue beech, or many others white woods that I have worked with are far as that goes. Not having experience with it I asked the question. It is in the birch family, but different genus. It gets high marks from many on here. Always had a tough time finding it were I live. A friend gifted me the log, and I was excited to make a few bows from it. As far as tillering goes I have no problems with black locust George, and Ed. I did with one bad wood log years ago. since then I have made some of my best shooters from black locust.Thanks guys for more info.
