insitu elliptcal arch

[sygooner]

Hi all.
I've got to run a staff bead on an elliptical arch in situ . If it was a semi circle i'd use a gigstick and cross brace but being elliptical can't help thinking it would be easier run on a rib rather than spinning from 3 points.
Gigstick or rib
Thoughts anyone

You need a bit of calculus.

Best ask Isaac Newton or get a spirograph
