wp, I like it. I'm surprised that you don't need the side curves. Interesting! I like it when common perceptions turn out to be wrong.

What did you use for rods? And mounting nuts and bolts?

A guy named mechanicalron used to hang out in the Mechanics section of bikeforums. I think he made some fenders. I'll see if I can dig up his thread. Maybe someone will beat me to it. His work was always gorgeous, and his approach was different in everything he did, so it's not really a comparable to yours.
