Good call,  especially in a practice room.  saves both money and time.  I'm doing two this coming year. BTW  Thanks to all about the Wurzen-Ronsen hammers for the Baldwin D.  I'm getting real happy with what's going on...  the conical front rail punchings really do make a better feel to the action.  No observation to tone improvement since all action was replaced!!  It all iimproved!!!!!!!

I do most of my restringing at the university using the same pins (removing old strings from them, and attaching new strings to them, same techniques as replacing an individual string, but mass produced). I only change to a new, larger sized pin when torque has become an issue for tuning stability. Reusing existing pins requires a different technique for restringing, but I find that, all things considered, it is probably a bit faster than changing pins.  Just another perspective. It does prolong the useful life of the pinblock as well. Regards, Fred Sturm University of New Mexico <a href=mailto:fssturm@unm.edu>fssturm@unm.edu</a>
