[pianotech] Kawai GS-50 damper tray

[Mark S Burgett]

Hi Laura,

Check the metal pin in the dowel that lifts the damper tray.  It the pin
is too long it can contact the tray.  I had this problem once and it
drove me crazy until I found it.

I found a problem I couldn't solve while I was at the piano and I
thought: "I know, I'll use a "life line" and ask the experts!"  You are
my "experts" so here goes:

It's a  Kawai GS-50 with a rattle in the damper tray when you release
the sustain pedal.  When I lift and drop certain damper blocks I can
kind of duplicate the rattle in the aluminum rail. 

I tightened the screws that hold the damper tray to the belly rail.  I
checked damper under lever screws.  I tightened the screws in the damper
blocks the hold the damper wires.  The tabs aren't hitting the sos. rod
and the Sostenuto rod bracket screws are tight.   The damper under lever
screws are tight.

What am I missing?

Thanks in advance for your thoughts.
