Seem to recall the bevel worked better than a radius because a) there was no
hydrodynamic disadvantage, b) it provided more add'l interior volume with less material,
and c) it was a hell of a lot easier to build!

If you bend the flat panels in a developable way you get the best of both worlds - ease
and economy of flat panels and the aesthetics of the curve.

I keep on hearing about the Kelsall "radius". Is this bagged and formed over a tube?
