I cheated once. Took a coffee can lid and made a hole very near the outside
edge for a pencil.

Put a straight edge at the bottom where the sine wave was to go and rolled
the lid across the straight edge, marking the plywood.

That's a cycloid, not a sine. Still far and away the easiest is to
use a graphing program like Graphmatica [download from
archives.math.utk.edu ...it's awesome and free.] Type in y=sin(x)
ENTER, and you then print from there or copy/paste into a word
processor. Less than a minute if you have both programs up and
running.

It can be done by hand, it can be approximated by hand. ifthat's good
enough then that's the best way, but most people don't have a clue on
how to do that.

Now, let's empty this can of worms and get on with it.
