Well so much has been said, that is helpful. I have done it and had it done too me. I build bows for a living. I am one of those fools that follows his passions,I guess. The glue you must use is smooth on. Not cheap either and needs a heat lamp.I would shorten the fades and taper or add a thin pc of wood to the bottom of handle to absorb the shock of the flex. Most handles pop, because of no rise in the handle area,( if it is a composite bow). I incorporate that when I build the bow.Yes I think your bowyer would make it right. If you choose to repair, ask him to send you some glue , warm the handle area with a hair dryer, and finish pulling the handle off.Don't force. Sand the bottom and ruff up the surface to be glued. glue both surfaces to be glued. Now wrap with saran wrap tightly.Put under a heat lamp, not too close and let hard.I wouldn't think wrapping the handle after it drys, I wouldn't reinforce with anything, as of the contour of the handle. The glue should hold. As to the design, My guess is when you unstrung the bow you accidentally pushed back ward against the handle forcing the bow to go opposite direction in order to relieve the string follow?This would start the process of de-lamination.However the shock of the shooting the bow could do the same. The laminated splice is quite commonly used. It shouldn't cause you a problem . With out the bow in hand that is the best I can do. Good Luck Denny
