Kenny,
We have been using this .125 rod for model aircraft spars. The .125 rod in the 12 foot lengths come shipped in about a 2 foot diameter roll. It bends easily and would go around the curature of the wing rib without a problem.

Jim Marske also sold a variety of square rod that may work better. I'm not sure if he still sells it or not.
Rick Mullen might be able to answer that.

However, if you used square tube, I think you could bond them all rather than use a mechanical attachment.  Where there is a will there is a way.  I was thinking you could make the tubes, as a minimum, out of unidirectional tape wrapped in the 2 oz glass.  Maybe 3/4 X 3/4 test that and see what it got you...
> You likely have to make the curved ones over foam, then eat the foam out with something... Â Just a thought.
