<DIV>I've been servicing the above piano for about two =
years.
According to the owner, it has always had a problem with keyframe =
knocking
and even after glide adjustments, the knocking always =
returns. I've
also found this to be true. On my last visit, repeated =
attempts at
glide adjustments including the ones reachable only from the =
underside,
were fruitless. I also observed that the treble keyend block =
was not
even touching the keyframe guide pin. Please note that =
I am
well experienced with keyframe levelling procedures.</DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV>My questions now are: should this piano have front rail =
keyframe or
keybed glides installed and can you provide those parts (ones =
similar
those on the underside of the center rail.) with directions =
for
installation? </DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV>and, what approach do you advise for
the ineffectual key end block situation? As a =
stopgap, I
put a couple thumbtacks on the underside of the front rail, which =
has
stopped the knocking. </DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV>I will be preparing this piano on Friday for performance =
use and
would appreciate any advice asap.</DIV>
<DIV><FONT color=#000080></FONT> </DIV>
<DIV>Thank you.</DIV>
