Jeannie,

I've done this with some success: from the side of the wippen, push a thin
rectangular X-Acto-knife blade between the wip "cushion" and the wood. (It
may be glued here, maybe not.) Just in the center of it, behind the capstan
impression. Then thread through a strip of centerpin bushing cloth, and cut
it off flush on the sides. A tiny drop of glue on the wood side of the
bushing cloth will make certain it won't work its way out (but probaby isn't
necessary).

You can do this without removing the wippens from the rail. This really
works to lessen the noise and does not create a "mushy" feel.

Regards,
Joseph Giandalone, RPT

Dan,
I did check that and I did think they were overly noisy.  Is there any way
to quiet down that area without replacing all of the wippen cushions?  And
if so, will it diminish the effect of the "great cornering ability"?

Thanks for your input.

Hi Jeannie,

Could Mr. Walter have specified a hard felt for the capstan contact
material? It makes for a 'no-wasted energy' resons to touch, but a nosiy
release. Kind of like stiff schocks on a sports car...great cornering
ability, but with the price of a bumpy ride.
    I test for that (hard capstan contact felt) problem by...

-Holding down the key, (behind the balance rail) and with the hammer out of
the picture, lifting and droping the whippen (from the jack toe) onto the
capstan, to see if I can duplicate the sound.

Let us know your result.
