This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Definately a puzzler. Did you look for gum on the backside of the = fallboard? ;-) And no, you are not stupid. You are correct. It can't click on the key = downstroke! Terry Farrell P.S. I like your writing style - very clear and entertaining! ----- Original Message -----=20 Here's a puzzler for you all; an unsolved puzzler at that. I've = executed a repair, but I have no idea why it works... Kawai grand, about 15 years old. There's a click on F#2, G#2, and A#2 = when the key is depressed. Not when it's released but at the moment = they're depressed quickly. (It won't happen on a slow strike.) I take the action out to check for loose screws, debris on the keys, = any anomaly, but nothing. In fact, the click is gone. I did tighten = one screw on one of the action rails, so, maybe that was it... Put the action back in, still no click. Reinstall the cheek blocks, = still no click. =20 When I put the fallboard back on, there's the click again. Pull the = fallboard forward to a 45 degree angle, no click. Back to vertical, = click, OK. The keys must be hitting the fallboard, but wait a minute. It = happens when the key goes down, not up. The fallboard does not extend = backwards inside all the way to the back side of the balance rail, so = when the key goes down, there is MORE clearance from the fallboard. If = the click was on the way up, I'd say it was hitting the fallboard when = it returned to the up position, but it happens on the way DOWN! Am I just stupid? Am I missing something here? My solution? I raised the fallboard so that there was more clearance = from the keys and now there's no click.=20 But how can the keys strike the fallboard on their way down and make a = noise? It doesn't make sense. It's not the upstop rail being depressed by the fallboard (That click = would happen on the way up, too.). I put felt on the backside of the = fallboard at the point where the keys would come into contact with it if = that was the problem to see if that changed the sound or eliminated it,, = but it didn't have any impact. I guess I should move on, because I fixed the problem. But I just = want to know: what caused the click? Any ideas? Did I describe this well enough? =20 Tom Sivak Chicago ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
