[pianotech] Another Damper Puzzler

[Ken & Pat Gerler]

Ron,
Another attempt I didn't note.  I lifted the dampers, blocked them up with 
the sustenuto pedal and then put a muting strip over the felt in the lift 
tray and then tried using the damper pedal - the sound was reduced (which as 
I am explaining this and have had 12 hours to think about it, says the 
capstan screws need to be burnished as they must have "something" on their 
surface that is causing the "extra" sound).  I did just rub my finger across 
the felt in the lift tray and I could hear the same sound.
