[pianotech] Damper tray block

[Gene Nelson]

I'll ask another question:
Assuming the damper tray is parallel to the key bed: And possibly it does
not need to be?
Thinking about the height of the key ends and how the key end travel can
vary across the keyboard as well as from natural to sharp, is it good to
have key ends parallel to the key bed? When at rest? When at full dip or
when they engage the lift levers?

Yes, it is....

And another question I don't hear being asked is about just how much weight
do the new Renner damper levers--and the WN&G damper levers, for that--add
when compared to the original non-articulated sostenuto type levers? Roughly
double. It can be fixed but it's extra work we shouldn't have to do.

Nope, and it wasn't a question. <G> It just seems to me that a group that
would sit in silence as someone seriously suggests that a unison that is out
of level will adversely (even perceptibly) affect letoff on shift needs some
consciousness recalibration, and this strikes me as a valid practical point
that has never been addressed on list or anywhere else I'm aware of. Level
under levers at rest present minimum friction, and at the bottom of the key
stroke, they rock up on the key end and change the lift ratio presenting
more resistance. Is that a good thing, or a bad thing, and why? THAT, is
definitely a question.
