I'm trying to build an oval bicycle wheel and need a formula to calculate the radii so that I can use the results to calculate the length for each spoke. See diagram for details. Hope someone can help.

Do you want the angle between adjacent spokes to be constant?

They were then advised of numerical methods for achieving this goal.
