[CAUT] Damper pedal noise

[Chris Solliday]

glue a piece of leather on the lever where the spring contacts it (clean the lever good first) and use cork grease to lube the contact. That will be the end of your difficulties. (Thanks to Kent Webb for this suggestion).

  Hi list,

  I service three older (1910s-1920s) S&S model As that get a similar grunting noise in the damper pedal.  At first, I thought the problem was the hole in the keybed where the pitman goes through.  I modified them all.  The noise came back.  Ahem.  The real problem is where the spring presses on the trapwork lever.  There is an indentation where the spring contacts the lever.  I've cleaned, cleaned and lubed with burnished graphite, cleaned and lubed with the white stuff, Prolube?, stomped on the spring to try to make it less strong, and am wondering if the real solution is to sand out the indentation, or change the spring or both. One of the pianos has a pretty big damper thump, so replacing the spring might take care of two problems. I suppose I could try one of each of the options and see what works.  :-)  But, the reality is I've already charged for the pitman modification and I want it to be over and solved.  What has worked for you?  

  Thanks,
