<p class=MsoNormal><font size=3 color=blue face="Times New Roman"><span
style='font-size:12.0pt;color:blue'>This is one area of piano work that for the
most part has failed in its evolution more than most. Even Steinway –
as reluctant to change as anyone – has replaced the bushed hole for
damper rods with a better idea. Even the wonderful Walter studio pianos have
the pedal rods (rough maple dowels) running through bushed holes that make horrific
noises. If you find a piano where the positioning of the rods causes a
lot of rub you’ll be much better off redesigning the system unless you just
love re-lubricating them each time you see the instrument. I wish I knew
how many damper systems I’ve redesigned to get rid of the friction noise
caused by that arrangement. Not all of those systems rub hard enough to
cause noise….it depends on how the levers are placed, but if you find one
that makes a lot of noise, a frictionless redesign is the best solution.<o:p></o:p></span></font></p>

pianos, K&C (Samick) and a PR . Both uprights, with same problem. Sustain
rod is making that scratchy noise . What is the lube of choice, does the
bracket have to be removed to apply? Should I rebush with new buckskin? Very
