, but you know the ends to a coax cable? One day I brainstormed this to fix a waist joint. What you do is get some epoxy putty and stick one end of the coax cable end into one part, after it hardens, you epoxy the other end into the other half. Since the screw part spins free, it acts like a new waist joint, make sure it's tight. It's the cheapest way I've found to fix a figure without sacrificing another figure... Hope that helps.
