The hinge is fixed George, as I understand it, which is why we are under weight. And you are right, we need to see the rested profile of the bow now, and another when the stave was still fresh before tillering in order to estimate the set taken, and likelihood the bow is game for higher energy storage. And look at the back ring thickness, and any blemishes, faults, knots etc. as well. Beginner is rough sledding, but informative. I thought about that when I suggested shortening, which I'm actually and very fond of when executed carefully, properly and under the right conditions. I think it can save some set actually.
