what

foot. Jim

<DIV><FONT face=Arial size=2>Although Rick Wheeler did several =
calculations,
while we were analyzing the probable action Geometry, the "end all" was: =
we set
the action at Half Blow and Rick had a laser that was a LINE! We marked =
the
wippen foot, with pencil at the "ideal" and I then went back to my shop =
and made
it happen. BTW, I should say, in this process, I made an "Action Model", =
(one
key on #1 & #88). AND, Rick utilized the original key frame, by =
making a new
balance rail and inserts in the front rail. (The original action had,
essentially, a 1 to 1 ratio in the keys! Yikes!<G>) This allowed =
us to
work unfettered at doing the analysis. The preliminary stuff was done in =
the
piano, (bore length, bore distance, action spread,etc.) so that Rick =
only had to
do the final analysis. What the formulae was, that he was =
doing...?...you'll
have to ask him. Since he is readily at hand, I don't feel the need to =
get into
the math part, at this time. Perhaps later. All depends on how many of =
these
puppies I will be doing.<G> As a lot of what he did for me, in the =
calculating, key making, is proprietary, in his eyes, I chose to be =
silent with
my never ending questions. (Now, there's a first!<G>)</FONT></DIV>
