Hah! Now all I need to do is figure out how to draw an arc with an

Two lengths of PVC pipe. Drill a hole in one end, attach a pencil

You've obviously never done this.

I couple of "trammel points" on a piece of steel pipe, along with two
humans, may work. What is your solution?

I gotta ask Bill why pipe instead of string? and for that matter I have
drilled a hole in a 25' tape measure and anchored a screw through that
hole and held a pencil at the distance desired.
