Bridge pin drills was Re: Bridge cap materials

[Farrell]

Has anyone tried the air hammer used for driving tuning pins to drive a bridge pin? Seems like you could make lightning strike twice in the same spot with that, or would it be more like a small nuclear device striking twice in the same spot? Maybe turn the air pressure WAY down and use a bridge pin punch? Maybe not?
