Avery, Back at national that happened on a piano we were voicing and we just backed off the one pin and took up on the other to move the string around a little. Can happen with aggressive lifting putting a little bend where you don't want it. If the piano is single-strung, as I understand, you may have to try lifting to ease the bend... There was something in the journal a while back about damage to agraffes too...that would require removing the string to polish the agraffe. Not your first choice ;-) Andrew Anderson At 06:00 PM 3/31/2006, you wrote: >List (& especially any of you major rebuilders out there), > >Do any of you have any direct experience with an SD-6 #118127 (1952 >I was told)?
