your key ratio David ?.. You might be lucky here and be able to get =

a quick move of the capstans in a couple of mils. If you are =
regulating well
at a shallow dip then thats a good indicator that you have some room =

<P>Otherwise... it would be helpfull to have a few othere parameters =

Friction -- obviously is good -- down weight bad. I hate =
adding lots
of lead to the keys, but on this piano there are only 3 weights in =
the bass
section, 2 at C4, only 1 in the upper treble, and actually 2 in the =
_back_
of C8. It appears that they did straight pattern leading on =
this
one. I can add 1 - 2 weights to each key and bring it down to =
44 at
A0, 42 at C4 and 40 at B7 (I'd probably just take out a back weight =
on
C8). There is a point of diminishing returns on some actions =
where you
can reduce downweight by adding leads but the additional inertia =
makes it
feel to the player as though it is as heavy as it was before. =
Does
anyone think I'd get into inertia problems adding this amount of
lead? dave <PRE>_____________________________
