<br>
Today I managed to find the elusive source of shift-pedal squeeks and
groans<br>
in a B, and with careful effort and attention actually made it
worse!<br>
<br>
Once I had determined the cause (spring against (wooden) key frame),
I<br>
carefully sanded the side smooth, applied a generous coat of DAG,
and<br>
burnished with a cloth.<br>
<br>
It worked instantly, and lasted about 3 minutes! Once the DAG was
well<br>
burnished, it began to groan as before, but louder! And now, in
addition to<br>
the fundamental, there were additional squeeks a major 3rd above and
major<br>
2nd below!?<br>
<br>
At a loss, I worked teflon powder into the graphite and with vigorous
use,<br>
the noise has not returned. Tefloning and testing the two contact points
of<br>
the spring seperately helped verify the source, as one "note"
of the<br>
non-musical "interval" disappeared with the first treatment,
then the<br>
remaining two.<br>
<br>
I fear this remedy will not last though, so what is your favourite tried
&<br>
true, long-lasting, never-fail, method?<br>
<br>
Thanks for your suggestions,<br>
