Ok, I ripped down some antler for my tip overlays. Now I assume that I just make sure both surfaces are flat and clean,perhaps roughed up a little and glue and clamp? Also wondering about narrowing the tips some more. The tiller is complete and the tips are about 1/2. Can I narrow them a bit more without affecting the tiller? The bow is osage if it makes a difference. This is my first bow and I want to thank you all in advance for the help.
