Ok, here is what happened. I was working on a stave that didn't have adequate handle material, so I glued on some handle wood with epoxy. I also used the same epoxy for the tip overlays, and one popped off, so I went back to superglue. Anyway, while tillering, the handle popped off also, so now I have a D bow in the works. Never done a D bow, so once I get it tillered and all, what do you recommend to give it some mass in the handle area?
You can take some thick leather like harness leather about 1/4" thick and layer it on the belly/handle area. Glue it then you can taper the ends to a comfortable shape then wrap with thin leather for the handle. It will flex with the bow
YOu will probably need more stiffness in the handle if you want to get your draw weight over 45 or 50lbs with stave 3/4" or thinner. I would recommend re sanding the flat for the handle with a flat board wrapped in sanding paper, or a flat belt sander, and flat sand the add on board too, then glue with a quality wood glue, like titebond, or a long cure epoxy and let cure 24 hrs. I have had good luck with gorilla glue super glue for tips, but I wouldn't use it to laminate the handle. Good Luck.
If you have a handle popping problem you have too much flexing in the fades. You can get a handle to stick by gluing on several thin strips to build up the handle area.
The thin strips will flex more than on solid piece and probably stay on. Use a glue like Urac or TB3
