[CAUT] squeak

[Jim Busby]

Les,

 

Personally, I'd thoroughly clean all the Vaseline off the glides and use
several coats of MacLube burnished with a soft cloth. Vaseline will be a
dust magnet and will sing loudly at some point. Lightly sand/clean any
wood too. Just my 2 bits.

Well, I went back and since there already was graphite in the keybed I
took patrolium jelly commonly known as vaseline and put it liberally on
the glides and it totaly stopped the squeak. I'll let you know if it
starts again.

	I had a similar situation with  an Estonia L190 -- I think it is
6'-4" or 6'-8"-- serial no. 6347.  I think it was manufacturered 3 years
ago.  All the aforementioned diagnostics/fixes were tried.    The
problem was isolated to be above the lyre and trapwork.

	 

	I also cleaned (even used a bit of naptha and Flitz) and
polished the action shift spring and lubed it and the key frame with
teflon.  It helped a lot, but the problem was still vaguely there, and
grew back in just a couple of weeks.

	 

	Another tech (three of us spent hours each going over this
piano) removed the action shift spring and gingerly (stomped on it)
reduced it's spring rate.  That again helped temporarily but the problem
returned.  Eventually, the  owner was given a  good deal on a new
Estonia by the dealer.

	 

	I know this history isn't helping you solve the problem, but I'm
wondering if the problem (in my case) is more complex than simply one
problem.  Could bad lubricant have gotten burnished into the key frame
wood to cause the spring  to squeek?  In my case, the squeek became
worse after continued use of the pedal.

	 

	Do you have indentations on the treble side of the keyframe made
from a "heavy" action shift spring?

	Could it be that a glide bold is loose and is shifting in the
key frame?

	 

	I'd really like to know what you discover on this one, Les.

	 

	73's!

		Hello, I hav a estonia grand probably a 6 foot it has a
squeak when you depress the soft pedal I graphited the key bed and it
totally stopped. But a day later it is back worse than ever. I also
adjusted the glides that were not adjusted properly I sure need help
with this one.
