A question about walnut board bows

[Steve Milbocker]

I see why a quarter sawn board makes the best board bows but what about walnut? If I understand correctly what I have been reading about building bows from walnut, it doesn't matter if you violate the back or not. So does it matter how the grain runs when choosing a piece of walnut lumber for a bow?

With all wood stave and board bows you should consider the grain. If you are goint to back the walnut bow the grain is not as critical.
