Hi Ed and Terry, The air hammer is the only way to fly, Buy a large chisel bit, cut the end off, and drill an indent just like a regular tuning pin punch. My blade is just over 4" long and give lots of clearance to see what's happening, 40 to 60 psi is needed fpr operation. A short burst with the trigger and you can just ease the pin down 1mm or less, thus ending up with the pins all at the same height in a very controlled manner. You end up with no marks on the pins, no bent pins, and much more even torque. I also use my string hook with some tension on the wire for the last, few mm's, and the coils do not spread. Just play with your air pressure to control the speed of insertion, It's about as good as controllable steam voicing one you get the hang of it. <G> regards Roger At 09:16 AM 20/10/00 -0400, you wrote: > ><<> Has anyone else tried an air >>hammer to install new pins???
