the part you think is a hinge,, what is the wood thickness like there??? the right limb looks a tiny stiff,, but I see the reflex in the unbraced photo,, so dont think you are much off,, I see the weak spot Pearl mentions,, again ,, what is the thickness there compared to the rest of the wood,,,can you tell from the grain if it is thinner or thicker,, I think over all it is looking very nice
