Had another question on this Stanwood stuff. grin.. I hope
I get a few more responses then my last....:)
<p>Ok.. so you have this basic Equation for balance and a bunch of charts
for different Strike Wt vs Strike Wt Ratios. These differ depending
on what Balance weight specs and all have the same Whippen Balance Weight
specs. These then represent "givens" for the equation of balance.
<p>I am wondering then if you can do the following:
<p>After makeing sure of correct action spread and confirming correct capstan
position and height for that spread, pick the strike weight ratio you want,
and balance weight spec. and then establish the corresponding strike weights
for the hammers. Adjust the whippen radius weight so that together with
the actual key weight ratio (dependent on the capstan position) you get
a match to the spec for the whippen balance weight. That gives you all
the numbers for the equation except the Front weight, which of course you
can solve for with these numbers. After solveing for FW, install weights
in the keys to match the solution. Now it seems to me that what ever discprepency
there is in the resulting real balance weight, and the specified balance
weight would be due to friction. And that you should be able to adjust
by dealing with the action centers and key bushings.
<p>Relocating the capstans would seem only to be neccessary if the
whippen balance weight spec is too difficult to obtain, <b><i>and</i></b>
if you cant achieve correct whippen travel distance when the height of
the capstan interesects the magic line.
<p>This seems like kinda simple really,,, so obviously I am scratching
my head wondering what I am overlooking... grin..
