Thanks, sirs. I have another question. Just how FLAT do the surfaces of the horn and the bamboo have to be, to achieve a bond that can withstand the stress of the draw? For instance, I was practicing scraping with two small pieces of wood, which you can think of as being like bamboo and horn. I cannot see any light between the sides of this little "bow" but there is a little wiggle room. If I glued together bow pieces like that, could I expect them to delaminate?
Also, when practicing on two other pieces, I tried making the "horn" piece concave, and the "bamboo" piece convex; a "female to male" type thing. Still, the pieces can wobble a bit even though you can't see light through the side.
