I picked up some micro-flite fiberglass arrows that have nib points on them. I believe that's what they're called. Just little cones protruding from the fiberglass shafts. They are/were used for target shooting. Anyway, my plan was to replace them with inserts and use glue on broadheads for hunting. Problem is, I can't get the buggers out. When I shot micro-flites in the 60s, we used hot melt glue to affix the inserts. I've tried heating the point with an alcohol lamp, and I've tried immercing the end of the arrow in boliing water to loosen the glue. No go. Obviously, whoever put these on didn't use hot-melt glue. Anyone have any recipies for softening other kinds of glue without ruining the shafts. Can't cut them off. I need all the length that's there.
