Terry, Why file them at all? Many new instruments are being manufactured with rounded bridge pins. I stopped filing pins years ago. I was always concerned that the heat generated by filing or grinding would loosen my new pins, also the sheer forces of the file enlarging the holes. Use the 1" replacement pins of the proper dia.( make sure that the hole is drilled to the proper depth. Bridge pins should be seated firmly at the bottom, not floating) . Use a nail set to fine tune the up and down alignment. They look great! BTW, I'm still looking for a source for reasonably priced nickle plated bridge pins (cosmetic reasons) .Most of the manufactures I've contacted are charging 15c APIECE. Why are nickle plated pins SO much more expensive than copper plated ones? Paul Dempsey Marshall University wippen@aol.com
