To All:

A couple of private messages commenting on the significant WEIGHT
difference between the big ribs, which weigh less than the little
ribs.

I believe the most significant difference is in the gusseting
material. The little ribs are gusseted with 1/8" doorskin material
whereas the big ribs use 'fiber' gussets... that is, heavy-grade of
CARDBOARD (as has been previously discussed). This rib is meant for a
PRIMARY GLIDER. Very low total weight and not much in the way of
forward speed. Plus, the big ribs are made of REDWOOD, each piece
selected for its light weight. The small ribs are meant for the wing
of a SINGLE-PLACE VW powered parasol. Other than for the methods of
rib construction, there is virtually nothing in common between the two
wings. The small ribs are made from much heavier PINE, and use
heavier wooden gussets.
