For those willing to build with epoxy, I think, the best would be to
purchase directly made sheets to be glued on rib

Not the cheapest way, but by far the quickest giving a superb
result.

Thanks Pascal

I have the wing rib problem decided. This is a teflon mold .75 inches
thick. The procedure is wet out the fabric and place it over the
center piece hole. Press the rib form into the center mold. the
flanges will be automatically formed. Put it in an oven set to 200 F.
Let cure.

Teflon is good to 500 F.

Each rib will be precisely the right size. Cut a hole for the spar
and use  sort pieces of carbon fiber angle to bond and pop rivet the
rib to the side of the spar.

This will be much faster then making each ribs out of foam and
covering it by hand  with fabric glass or carbon.

Pardon the "Captain Obvious" visit... The same process works very well for bulkheads and fire walls. Screw the hole plug to the base also for accurate hole location of wire/control looms. A piece of fiberglass tubing inserted would give a nice clean finished hole.
