Yep. A previous owner installed some extra hardware on the bowstem. It was one long bolt at a crazy angle. The nut down below was pushing into the wet core. After a very miserable few weeks with my head, grinder and fiberglass materials in the bow I had it back together. I ended up using an epoxy stick to build up around the exposed end of the bolt. At the end I put a fender washer so the nut would have something solid to push against. Don't underestimate the strength of this stuff. It's harder to grind away than fiberglass
