noisy Schimmel action

[marcel carey]

Hello Richard,

With the action out of the piano check the following:

Is there travec of backcheck leather on the hammer felt? When you gently 
tap down on the hammers at rest, does that reproduce the wooden noise?. 
It could be that the hammers are tapping on the backchecks on return. 
Sometimes by just raising the hammer line you could get rid of the 
noise, sometimes not. If anyone has a cure for this situation, I'd be 
interested in knowing.
