<DIV><FONT face=Arial size=2></FONT><FONT face=Arial>I need to =
tread this water
carefully because I am aware that I am no expert on this subject. But
most responses to this question have included suggestions
regarding changes to key leading or action geometry. I would =
suggest
that if DW was a "pretty even 52 grams" and then "two weeks later, the =
weight
was back over 60 grams" the solution will be found in regulating =
friction. The
source of such DW changes necessarily excludes issues of key =
leading and/or
action geometry - unless, of course, these factors are changing over the =
course
of two weeks.</FONT></DIV>

was that this Boston<BR>> grand piano action was causing the owner, =
who
practiced about 5 hours a day,<BR>> was getting pains in his =
wrist.
However, when he practiced on his church<BR>> piano, a Steinway =
grand, he had
no pain.<BR>> <BR>> The starting downweight was over 65 =
grams. After
I eased the balance<BR>> centers, cleaned the center pins, put teflon =
powder
on the knuckles,<BR>> adjusted the repetition heights and the jacks, =
the
downweight was a pretty<BR>> even 52 grams and the guy was =
happy.<BR>>
<BR>> Two weeks later, the weight was back over 60 grams and his =
