[OS X TeX] Angular Vernier scale

[Aaron Jackson]

I have to make some documentation for a piece of scientific equipment. This will entail making quite a few illustrations of different settings on an angular vernier scale, similar to the one show here

Does anybody know an easy way to draw this sort of scale?

Thanks,

Aaron
