<DIV>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...</DIV>
<DIV> </DIV>
<DIV>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.)</DIV>
<DIV> </DIV>
<DIV>I take the action out to check for loose screws, debris on the keys, an=
y
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...</DIV>
<DIV> </DIV>
<DIV>Put the action back in, still no click. Reinstall the cheek block=
s,
still no click. </DIV>
<DIV> </DIV>
<DIV>When I put the fallboard back on, there's the click again. Pull t=
he
fallboard forward to a 45 degree angle, no click. Back to vertical,
click,</DIV>
<DIV> </DIV>
<DIV>OK. The keys must be hitting the fallboard, but wait a minute.&nb=
sp;
It happens when the key goes down, not up. The fallboard does not exte=
nd
backwards inside all the way to the back side of the balance rail, so when t=
he
key goes down, there is MORE clearance from the fallboard. If the clic=
k
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!</DIV>
<DIV> </DIV>
<DIV>Am I just stupid? Am I missing something here?</DIV>
<DIV> </DIV>
<DIV>My solution? I raised the fallboard so that there was more
clearance from the keys and now there's no click. </DIV>
<DIV> </DIV>
<DIV>But how can the keys strike the fallboard on their way down and make a
noise? It doesn't make sense.</DIV>
<DIV> </DIV>
<DIV>It's not the upstop rail being depressed by the fallboard (That click w=
ould
happen on the way up, too.). I put felt on the backside of the fallboa=
rd
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 ha=
ve
any impact.</DIV>
<DIV> </DIV>
<DIV>I guess I should move on, because I fixed the problem. But&n=
bsp;
I just want to know: what caused the click?<BR></DIV>
<DIV>Any ideas? Did I describe this well enough? </DIV>
