<DIV><FONT size=2>If the keys genuinely have no lead in them, then =
taking weight
off the hammer is probably a mistake. I would guess they are on =
the light
side since 60 grams downweight with no lead (depending on leverage) =
suggests a
pretty light hammer to begin with and there should =
be plenty
of room to add weight to the front of the keys. This is an area =
that
really requires looking at the whole picture to assess leverage and the
relationship between the front weight of the key and the hammer =
weight.
Read the Stanwood articles I suggested earlier. They will give you =
an idea
of the things you should be thinking about.</FONT></DIV>

TYPE="CITE">Hello All: I have hung some new hammers and shanks on =
the action
from a Edmund Gram baby grand. It has no key weights, and with =
the new
parts the downweight on all the keys except the upper two octaves is =
in the
60+ gram range. The friction levels in the upper octaves are =
acceptable, and
as the rest of the action has the same parts and has been =
reconditioned the
same way I don't believe that friction is the culprit here. =
However, I
have never weighted an action before. I am going to look =
through the
Journal CDs for articles on weighing off an action, and would =
appreciate any
advice or input as well. Is this a case of fools rushing in =
where
angels fear to tread, or an opportunity to learn a new skill? =
Thanks,

weight
of hammers. Did you by any chance keep the old hammers and shanks? If =
you did,
weigh some of them, and then weigh the new ones. According to Wally, =
one once

If you

shank, and see if that reduces the downweight. <BR><BR>Wim
