: I would take a rope and mark the three foot length. Then with one
: end attached to something reduce tension on the other end until
: it has the dip you want and measure the distance. If the shape
: is too parabolic you could do the same with a strip of your
: plywood and support each end on a case of beer and press down.
: Adjust until you like the curve.

A batten bent around a single point will form a hyperbola which is a close approximation to a parabola unless the angles is large . . .
