</pre><font face="Courier New, Courier">Chances are that if the wires
were making noise in the guide rail bushings<br>
then they are slightly oxidized and need polishing to further reduce
noise<br>
and wear, and more importantly to reduce friction to dampen
better.<br><br>
The front trichords can be trimmed in the piano with a little care. A
pair<br>
of pliers squeezing the wires behind the damper will pinch the felt and
a<br>
razor blade can trim the felt flush to the bottom of the wire
(pinching<br>
is not necessary but will insure that the felts do not tear).
Trichords<br>
on the rear will need to have the damper removed. But it is the
trichord<br>
on the front which makes the most noise especially if they go to the
upper<br>
reaches of the 4th octave.<br><br>
If possible, I like to remove the damper. This way I can also pinch the
tips<br>
of the trichord with round-nosed pliers to further reduce drag and seat
better.<br><br>
When it comes to grand dampers, I'm no whoosh.<br><br>
