How about a mixture of wood alcohol and water to cause the bushing to =
swell, thereby loosening the pin?  Might work.

Once the action is dried out, what's to prevent the moisture coming back =
and the action centers becoming sluggish again?

Joy!

  Greetings,

              I went to a home where there was a Chickering console =
piano that the hammers return at a snail's pace after the key is struck. =
I suggested that the hammer bushings around their center pins may be =
swelled due to humidity resulting in tightness and friction causing the =
slow motion return.  He had a heater bar in the piano and I suggested =
that he plug it in to dry up some moisture. He did. Two weeks later he =
calls and tells me it only helped allittle and the thing is still =
unplayable.=20

               I am thinking that the only thing left to do is to bring =
the action home and put it near a radiator so they dry out, and give =
each pin a shot of protek. Any other suggestions?=20

  thanks,
