Hi Ric, I'm using the adjustable hammer flange friction bolts as teaching tools these days... If any of you are serious and want to experiment I'd be happy to provide some samples. David Stanwood >> >>Hi Jim. >> >>Point taken, and I think I understood you from the beginning. I'm >>assuming that the kind of differences in tone that a looser pin will >>make are different then a shank with a soft spot causing an abnormally >>low resonant frequency.
