Make a root rib and a tip rib. Mark and drill holes to exactly center ribs properly.

Cut rectangular rib blanks and drill matching holes, 1 blank per rib. Fasten ribs together, usually with a long bolt. Carve and sand until the outline flows smoothly from root to tip.

Separate and voila, tapered ribs.

This is the process Jim Whitley describes in his Daddy Rabbit article. It works...

Rib # 8 in the DR is sure off by a lot though!! I can show a file from a Gordon Whitehead book on how to draw out tapered wing ribs but it's easier to draw out the root rib and end rib then use spray mount glue to glue up sheets of balsa between these two ribs then tilt the band/scroll saw table so the blade can touch the first and last rib then just cut and finish sand.
