I agree. There would be litle overspray to create a mist, as I would blow
directly into the felt mass. There would be volitiles leaching out of the
hammer felt, and ventilation should be provided. But certainly nothing more
dangerous than Flor'da lightnin' water. I would like to have a little
velocity so as to flush the now-liquid solids out of the crown. Just the
velocity of the felt's inherent wicking would be too slow to move solids.

Air of course could do it, but if the fibers were really stuck together by
the reinforcer, playing air n them with any reasonable pressure might
damage them mechanically. I'd prefer the reinforcer be disolved rather than
hard and unyielding under the stream of pressure. (Air, acetone, lightenin'
water, whatever.)

It's worth a try, if anyone has a piano in their living room I can come &
practise on. I'm also tossing the idea out to see if anyone has had similar
ideas (or even "been there, done that, and had their malpractice insurance
jacked up because if it").
