Planning a red oak board bow with 2" billets, stiff handle. Is it ok to shape the handle with the glue joints, it won't weaken the joint? Also, how do I put some reflex in, if I wanted to, just join the pieces at an angle? And how would the handle block be glued on the bent joint? I see that either the joint has to be flattened on one side or the block has to be shaped to match the 'V'.
