Sounds like a common problem. Drawing it the extra 1 1/2" didn't help much. The problem is when extra wood is glued on for a handle, if there isn't enough ridgid limb before the handle fades, the handle will pop off. There is a coulpe of ways to fix this. 1. you shorten the handle piece so it doesn't bend with the limb. 2. Glue another handle piece out of a bunch of laminations like plywood, and that will help, still leaving this a little shorter. 3. You can form a handle out of stacked leather, glued together with super glue, sanded and shaped the way you like. 4. This does'nt always work, but you vcan clean the piece that poped off and the bow, re-glue it and drill some dowel rod in a few places in the handle. But this will only keep it from coming completely off.
