(Just a little, and for just a little while.)<br>
<br>
I’m going to replace the damper action in our old Steinway D in a =
week or
so. Putting in a new Renner system. This brings up a =
question I
have had for a long time and have never got a good answer. Why is =
the
tray pivot pin not in line with the underlever flange pins? When I =
try to
visualize the motion of the underlevers and tray, this seems like the =
best
place for it. Having the tray pivot pin offset seems to be a major =
factor
in the unpleasant phenomenon of the underlever pushing down on the back =
of a
depressed key when the sustain pedal is used. Yet every =
manufacturer I
have seen, and the Renner instructions, puts the tray pivot pin behind =
the
underlever flange pin. What am I missing?<br>
