A few years ago I performed a "highly sophisticated" calibration of an
unknown meter against a standard (now unavailable) Jim Jones B torque
meter. I asked my wife to record two columns of numbers. I held both
meters in my hands and twisted one against the other. I read each meter
aloud for 6 or 8 points. When I put the numbers from my wife's record
into Excel, I got a good straight line. It did not go through the origin
but it was close enough. Maybe 30 minutes total. Like I said "highly
sophisticated". <Grin>

Most CAD programs can readily plot a dial face onto paper. Even
divisions are not required, but at least a one-point calibration is
required.

None of this is as good as a Gowen meter, but it can be made to work
fairly well.
