  As someone else mentioned, you have to be very careful using this =
technique.  I'm sorry if I didn't mention this earlier.



  When using such a device, I would not let it touch for more than =BD a =
second or so.  You don't want to heat up the pin enough that you do =
damage to the birdseye (of course).



  And I might have also prefaced with the fact that I like to "fix =
things right".   So given the time, I would always like to fix the =
problem, rather than mask it.

  Jonathan,
          I can accept that this is effective for the bushing cloth =
around a center pin but what does it do to the bridseye?

  Dave, we used to use in the shop what we called the lazer tool

  If youd like Ill try to find the plans for it (or someone else might =
already have some)

  Basically, it is a pair of tweezers with low voltage running through =
them.  You pinchthe tweezers over the ends of the pin, and vuala!  Youve =
loosened it.  The current through the pin causes it to heat up, and =
thereby presses the felt inside, almost like ironing it. =20

  =20

  I know I know, it has nothing to do with lasers, but thats just what =
we called it!  (because of the hum it created)

  =20

  But I tell ya, I never have had the effects wear off (seems to be =
stable), and Ive found no better way short or repining everything to fix =
a whole batch of tight pins.

  =20

  Anybody else with such experience?

  Ladies and gents,=20

  I went out on a service call last week to deal with a rental piano =
that had sticky keys.  It was a Kawai console that was in a room =
approximately six feet from an open window.  It IS January, and even =
though this is California, there was a substantial amount of cool, damp =
air blowing in from outside.  After a brief and kindly lecture about the =
evils of drafts and temperature/humidity fluctuation, I set to work.=20

  There were many sticking keys and sluggish hammers.  It was tight =
centers, so I figured, hey, CLP will do the trick.  I was wrong.  For =
whatever reason, there was no noticeable improvement in the =
sluggishness. I assume that none of the excess fluid gets absorbed by =
the plastic as it might get absorbed by wood.  Anybody know for sure?=20

  I reamed a few flange bushings and replaced some corroded pins and the =
situation was resolved, but a less time-consuming solution would be =
desirable..  Anybody got an answer, and/or a lubricant that might work =
with Styran?  =20
