This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hi Don I encountered a the same noise back in September. David Anderson posted the following response and his solution worked very well for me. I think there is a hard felt problem there, but David's solution apparently is a work around if you don't want to change the felt.

After assembling it I notice a distinct click when the jacks reset. It appears some errant chemical vapor from the shop has hardened the jack stop felt causing a slight noise on the reset. I'm thinking perhaps a couple drops of water/alcohol/surfactant solution might do the trick to soften the little round piece of felt. Anybody have any input? If you're describing what I think you're describing, this is very common on many Asian actions....and it's not felt-hardening, but something to do with the jack position being too far back, and the whippen itself somehow magnifying the "pock" sound that results when the jacks pops back under the knuckle. Try weakening the repetition springs and reregulating the jack position(a little farther forward than usual) and height (so the hammer barely moves on a test "wink") on one note; I believe the noise will diminish or disappear. Hope this helps.... David Andersen ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
