I am struggling with how to calibrate my test club. I won't bore you with all the things that did not work. And this may not, either.
The present problem is how to correct the reading on the scale for the geometry including the offset between the pivot on which the airplane rests and the centerline of the crankshaft.

I already understand there is an issue with the sideways force on the ball or rod on which the airplane rests, but the analog scale under the wing is where I can measure force and convert it to a torque reading.
I am considering taking a tangent off the arc, the center of which is the crankshaft and correcting the down-force reading with normal trig, assuming the actual torque is the tangent to the arc where the arc intersects the hardpoint that presses on the scale.
I already know there is a vibration issue, so don't even go there. I'm looking for a geometry solution at this time.
Thanks in advance
