Any precision drawing package will be OK, especially if it has
facilities for laying out lines at specified angles to each other.
I've regularly used AutoSketch for re-scaling meters, including multiple
and non-linear scales.
AutoSketch has a number of useful features, including ability to enter
angles precisely from the keyboard, and to repeat one mark around the
scale at specified angle intervals. You can also change the thickness or
length of every 5th or 10th mark, and place calibrations around the
scale, rotated to the correct angles. It all takes some practice, but
the results look very good indeed.
How do you print on clear Mylar, Terry, and how do you stick it to the
panel?
