From time to time, I use an egg pin with a universal clamp. The clamp has squeezed the collar of my endpin such that the screw with which one secures the endpin no longer goes in through the hole in the collar. I think that a collar made of a stronger metal would prevent the problem. Does anyone know of any machine shops preferably close by NY, NY that might be able to take my existing collar and duplicate it in titanium? How much should I expect to pay? Any other suggestions?
