It made her jump up and look to see what was "in there". She played a few bass notes over the phone and you could hear a definite action clatter. Then she noticed it was occurring when she released the key. I guess I'm revealing my age when I say I know the "sound of cellophane". I think the thing noticed most about cellophane was the rustling noise that had an unusual crackling/pop noise with it. Nothing quite like it. If you guys don't nail this one, I'll be surprised. This is probably going to take me into my next field of study. I have a good understanding of key dip/hammer blow distance/let off though I've heard talk of a safety factor/relationship that I would like to know more about. I've taken Nick Gravanite? Action geometry and Wally Brooks, effective weight control and couple of grand regulation classes. Now to the repetition lever. My guess, and it's purely a guess, the noise is the rep lever going through it's cycle. Guy Nichols class, Extreme measures, he said "pop and buff" the rep springs. What's the best way to do that and is that anywhere close to my problem noise?</font><br> <font face="arial" size=2>By the way, Guy's class is a good one to take after lunch. you won't fall asleep. </font><br> <font face="arial" size=2>Keith R</font></blockquote><br> <blockquote type=cite cite>><font face="arial" size=2>occurring whe= n she released the key. </font></blockquote><br> My first inclination is towards damper noise.
