<DIV><FONT face="Verdana Ref">Steinway 1098's certainly have a lot of friction
from the pin, over that cast plate nut and felt, and then through the pressure
bar! It's a great place to lubricate. BTW, Kent Webb mentioned that
the current production of this scale now has eliminated that cast plate nut
entirely.</FONT></DIV>

accidentally dumped lots of Protek on a grand pinblock, they did an experiment
in the shop on a piano to be rebuilt. Applying Protek liberally directly
to a tuning pin affected torque, alright: it went <STRONG>UP!

before!</FONT></DIV>

<DIV> Also, remember that there is some friction of the
wire over the bearing points. Some pianos have a lot, some have almost
none (Steinway uprights). If the pitch doesn't change right away when
you turn the pin, you have friction that is preventing the sliding of the
string. The understring felt is often the source of friction here, and
you can put some protek lubricant on the string to help with this. Just
don't go hog wild and allow the protek near the tuning pin. I use a hypo
oiler and put the tip of the oiler along the strings in the felted area.
Just don't use any petroleum based lube here (WD-40).
