[CAUT] Lighter Touchweight

[David Love]

I guess I'll have to revisit the formulas (or my action model-wherever the
damn thing is).  However, just from an empirical point of view, I have had
success in reducing touchweight slightly by shimming the wippen flange (or
rail) out.  Whether or not it is as effective as moving the stack, I'll have
to take your word for it for now.  Admittedly, it's not a solution I usually
consider for wholesale leverage changes.

I disagree that the advantage is taken away at the Knuckle

 

To calculate the ratio of the wippen measure the flange center pin

to the knuckle rep lever contact point (I think at half blow) divide

that by the flange center pin to capstan/cushion contact point.

 

No where is the jack center involved in ratio computation.
