We have relocated knuckles on three pianos (2 Bs and 1 D), >with generally wonderful results in both touch and tone. I moved the knuckles on a 60's S&S B due to a mistake. During the parts selection I took the wrong set of shanks & flanges from the cabinet and proceeded to install all the parts. (Yes I know, dumb!) It was not until final regulations, when I knew something was wrong, that I discovered my incorrect parts selection. The knuckles were closer to the flange pin than spec. for this piano. Of course jack to knuckle core alignment was off and the up/down weight as well. Rather than pull the hammers I decided to try pulling the knuckles and setting them at the proper distance. (It is great to be working in a school where one can do this sort of experiment.) The Hart knuckle removing tool came out about this time so the job of pulling the knuckles went fairly well. I made a jig for the band saw to get a consistent cut and proceeded to widen the slot for the knuckle core. I used small pieces of veneer to wedge the knuckle tight in its new position, using Titebond glue. The piano is used hard during semester and I have never had a problem with it. I would do this again if the situation warranted. Don McKechnie Ithaca College dmckech@ithaca.edu Mark Your Calendars Now For NYSCON 97! October 17-19,1997 Radisson Hotel Corning, NY 1/800-4-NYSCON
