Here is how I got to the fix in the last post.
I put the strip of leather on the back. Then took sinew soaked in warm water and wrapped the area over the leather and around the nocks. Let it dry overnight. Then applied 3 coats of Superglue to the sinew.
I have mentioned a few times while running into problems with this bow that I use SuperGlue. Here is what I use. It very thin so it penetrates cracks deep into cracks and it works great on sinew. After gluing the sinew and letting it dry, I was able to use a rasp and sandpaper to smooth out the sinew.
