Yes, unfortunately that is original. They changed over to the
plastic/delrin/whatever a few years ago. The first I knew of it was
trying to get a click out of a repetition in a rental D. I chased it
down to the coil whacking against that post. <br>
<br>
I believe I heard the suggestion from a Steinway person to twist the
coil of the spring to get rid of this, Personally, I prefer the old
system, which if I remember right was bushing cloth with a center
pin through it. Damper cord would probably work -- it certainly has
held in plenty of springs in other actions. <br>
<br>
It seems to me that people designing pianos have a fond illusion
that just because teflon is low friction, it's also quiet. But it
does not absorb or deaden sound at all, nothing like the action
cloth or bushing cloth it replaces. (Think of all the tiny little
squeaks from spinet and console damper springs when they stopped
putting in the cloth lining at the end of the lever and just sprayed
on green teflon.) Since the noises which get going with it take
awhile to show up, presumably the designers continue to think that
teflon is noise-free. <br>

Surely too there is some risk of noise arising from the working
of the spring coils against the relatively hard surface of the
plastic? What should be in there is Flange Cord, the correct
material. It's a special material with a braided sheath
covering a bundle of threads inside. I will try and send a pic
shortly.<br>
