Ohh, it makes sence you might get set. It seems like a strong backing, especially one that doesn't stretch much like flax or linen, would stop the back from doing as much work. Like the wood wouldn't stretch as much as it would without the backing. So that forces the belly to be compressed more, right? Another thing is how the thickness and width affect the compression on the belly. I thought at first that a wider bow with a thinner thickness would be overtaken by a strong backing first. But then after thinking about it, doesn't a unbacked bow fail because the compression of the belly is too much for the back to take? Wouldn't stretching the load by widening the bow and reducing belly thickness, in effect reduce the amount of compression going on? I know wider limbs with thinner bellys bend more because there is less compression pushing against the back. There for, reducing the chance for compression failure? Of course, this is providing perfect tiller, as it still makes sence of one hand that if a bow is wider and thinner AND has a tiller flaw, a backing which causes more stress on the belly would stress the flawed area and brake it before a thicker bow would brake, right? I never fail to confuse myself. Would it be the other way around, if a bow was thicker in belly the backing would be less likely overpower the belly? Like when a bows belly is trapped because of it being compression weak?
