The string was just placed between the two points, held with a tack, to give me a flat plain the move the ruler along. Probably my best measurement idea yet if allowed to toot my own horn for a bit.
Grating is 1000mm,
I will be using that calculator, as I don't have a graphing calculator to do all these functions.
Also, yes, this won't be perfect, but if there is a pattern between three lines, or if it is accurate for three, then the 4th will follow suit.
Also, the 594 line isn't 1653.5mm, it's 1743.5mm. I am getting fatter fingers...
