[pianotech] S&S Damper thump

[David Love]

You can also try regulating the lift so that the dampers don't rise or set
quite uniformly front to back, i.e. the back lifts first, or the front for
that matter (just slightly) so the dampers actually kind of rock down onto
the strings rather than fall straight down with the front and back seating
at the same time.  Changing damper felt may not solve the problem.  Also,
remember that an insensitive foot can always make a thump and that higher
tension in the trap work tends to get the foot to release more rapidly.

Try reducing the clearance height so the dampers don't fall so far.

Hi all.

I ran across a S&S L (1967) today that had really loud thump 
when the dampers come back to rest. At one point, I had 
enough spring tension on that part of the trap work that I 
could barely press down on the pedal, but the thump was 
gone!..obviously not the correct fix.

I'm thinking that the only fix for this is to change out the 
damper felt.

Are there any other thoughts? I appreciate them.
