<DIV><FONT size=2>I would start with the November 1990 PTJ entry by =
David
Stanwood, Mastering Friction with the Balance Weight System. It =
will show
you that you should be using Balance Weight, not downweight, as the =
standard and
will give you one procedure. One caveat, there is a lot more to =
this than
just adding lead and it involves taking some precise survey measurements =
before
you start changing parts. But it seems this is after the fact now =
so this
will give you a start. For further reading I would check =
Stanwood's
articles in the Feb, March, April 2000 issues as well as the June
1996. </FONT></DIV>

<DIV><FONT face=Arial size=2>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, Patrick Poulson,
RPT</FONT></DIV></BLOCKQUOTE></BODY></HTML>
