[CAUT] Damper pedal noise

Where does one find "cork grease"?

Thanks

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,
