<DIV><BR></DIV>
<DIV><FONT face="MS Sans Serif" size=2>It appears that the SBR =
(leverage) is a
bit high in this piano. You need to provide a bit more =
information but
it seems to average approximately 6.2. My guess is that the =
knuckle
position is 16mm and it should be 17 mm. That would lower the =
ratio to
approximately 5.8 (average) and would be sufficient to lift the =
existing
hammer weight without excessive front weighting. Depending on =
the
situation I would consider moving the knuckle. Since you =
didn't
provide upweight and downweight information, I don't know what the =
friction
component is. But moving from a 16 - 17mm knuckle will also =
lower the
friction a bit. You might also check the capstan line. =
Measure the
key ratio in the bass as well as the treble to see if the key ratio =
changes
through the piano. Another possibility is to move the capstan =
line
forward in order to achieve a uniform key ratio and reduce the =
leverage to the
necessary level at the same time. I wouldn't take any weight off =
the
hammers, they are not that heavy to begin with. </FONT></DIV>
