Don't the centerpins run through bushing cloth just like any other =
action?  I don't understand why the plastic has anything to do with the =
sluggishness of the centers.  Maybe reaming for a little more clearance =
might be a better solution.  Lubrication may not be the answer to overly =
tight fitting pins.

  Winter in central California often means sluggishness in pianos, =
because many people choose to leave windows open in the vicinity of =
pianos, just to let in a little "fresh" air, which is usually quite =
damp.=20

  Went out to yet another house where another Kawai upright had a =
"sticky key".  The hammer flange bushing was once again the culprit.  =
According to a response or two I got to my last post, the plastic wasn't =
the culprit.  Since this piano is less than a year old, and the pins =
aren't corroded, I once again tried CLP to determine if it would work on =
centers in plastic parts.  =20

  I won't say that it didn't help at all, but the lubricity effect was =
minimal, at best.  Inadequate would be a better description.  Nothing =
like what CLP does on wood parts(even in funky old instruments that =
would be better off put to sleep).  .=20

  I anxiously await my shipment of Goose Juice(and summer!).=20
