Ok, I'm wondering if someone can help me out here. I am trying to build the backside of the attack disk in vector but I am at a total loss of how to calculate the position of the ticks on the scales. I can plot a sine wave on paper but can't for the life of me figure out how to put the values on a wheel, i.e. right numbers at the right angles.
I have spent well over 2 hours on search engines and can point you to a dozen or more sites that have slide rules of all types and shapes for download, but no one discusses the math behind the scales.
I'm sure that at least several people on this board can do this in their sleep and if you would care to slide (ooh! a pun!) a few formulas my way I would be grateful. I will be sure to post my files when finished.
