<DIV><FONT face=Arial size=2>I would second Barbara Richmond's suggestion.

<DIV><FONT face=Arial size=2>First of all,are you 100% certain the friction is
in the damper guide rail bushings. Make sure that the problem is not in the
underlever pinning. </FONT><FONT face=Arial size=2>But if it is in the guide
rail bushings, I would shoot for stabilizing the felt</FONT><FONT
face=Arial size=2>. </FONT></DIV>
<DIV><FONT face=Arial size=2>Use the old and true method of
treating stubborn center pin bushings in the action. Mix 50% water/50%
denatured alcohol and with an eye-dropper or hypo-oilier, putting several
drops in the damper guide bushing. Initially the solution will swell the
bushing, but hours later the bushing will return to it's original size. The
difference is that the felt will be in a more stabilized
condition. </FONT></DIV>
<DIV><FONT face=Arial size=2>Once treated with the solution, I would then follow
up with the Protek Prolube and you'll have a very long lasting
repair. </FONT></DIV>

some material needs to be removed. I've had to do this. I took a
rat tail file and twirled it lightly in the guide bushing cloth and removed a
small amount of material (threads). One must be careful--it's possible
to grab the whole bushing! Then I took a spare damper wire, heated it
and ironed the hole. Next I treated the cloth with
Protek. I had thought of using VS Profelt, but I didn't want
to go through the swelling and shrinking thing and having to drive 40 miles to
come back and check to see if everything was working. BTW, it's possible
to listen for the amount of friction in damper guide rails--well, you can hear
it in a quiet environment. Have a listen... <BR><BR>Barbara

The Piano is a Steinway M. Perhaps 40 years old. Sticking dampers
are a reoccurring problem. I have eased the damper holes,<BR>and used
0000 steel wool on the damper wires and still the dampers stick with any major
weather change. For some reason the<BR>customer is not interested in a
Damp Chaser being put on the instrument. I can use some suggestions on a
fix that would be<BR>longer lasting. HELP
