Sticking Center Pins on Steinway Vertical Piano
By Eric Shoemaker

Out here in the Pacific Northwest sticky center pins in a variety
of actions are common.  I think that most technicians would agree
that replacement of the flange, butt and pins is the proper thing
to do on a Steinway.

However; if you can find someone willing to sell you "Perc"
[perchloride] (I get mine from my dry cleaners) and you use it
*sparingly* this will shrink the bushing sufficiently to cure the
problem.  Use a hypo and only _one drop_ on _only_ the worst ones;
too much solvent will cause the felt to shrink so much that it will
fall out.

I've done this hundreds of times in small spinets (Acrosonics, Lesters,
Wurlitzers, ...) and this has always solved the problem.  Personally,
I wouldn't use this "quick fix" on desirable quality instruments but
maybe as a temporary solution until the proper replacements arrive.

Not always all wet in Tacoma,
