I made several "jigs" by printing out the simplex airfoil, gluing the
printout on a piece of "2 x 2" pine, then cutting to the line on the
bandsaw. I soak a piece of like 1/32" balsa and clamp it in the jig -
either just let it dry or bake it. For a thicker rib I use 2
laminations glued with Elmer's. Then just strip the width I want The
percent I use most is 6%.

IMHO it makes for better ribs than cut ones.

As far as a formula for what % you want, have no help there at all.
