Rick, We do this a lot, and there has never been a problem. Sometimes you may need to rap the pins lightly with a rubber mallet as you lift gently on the plate to make the plate let go. It has never failed to release, or to go back on nearly as easily. It sure makes life easier to re-notch, clean, and do other work. One of the 999 tricks I learned from Ron N.

David's response was to the question of how he deals with evening out torque on the occasions in which he does replace the pins. Such times would include stinging with bridge and/or soundboard work on a Steinway (or other full-fitted pinblock) where keeping the pins is not a viable option. We have talked about attempting to pull a plate with the pins intact, but to this point, I have not seen a Steinway with the pinning angles and drilling consistent enough to attempt it. Has anyone done this successfully? I would love to hear about it if you have. ____________________ Rick Florence Senior Piano Technician Arizona State University School of Music ________________________________ From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of Fred Sturm Sent: Thursday, July 24, 2008 10:39 AM To: College and University Technicians Subject: Re: [CAUT] existing pinblock prep On Jul 24, 2008, at 10:42 AM, David Brown wrote: Re gun brushing- Sometimes when going from # 2 to # 3 pins in a piano where the torque levels are adequate ( 90 - 120 inch lbs , say ) the # 3's can end up a little tight My own attitude in this situation is why change pins? 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 fssturm at unm.edu
