Erich,

For Simplex ribs, always trim only the TE to fit. This is supposed to give a constant percent thickness regardless of rib length. Program to plot the rib template should be in the Indoor_Construction downloads section.

Regarding the plans in Ron Williams book (page 90), the rib airfoil
used is described as: 6% "simplex". This airfoil doesn't look
symmetrical. The high point seems to be near the front. The platform
for this plane is somewhat elliptical. So some ribs will be much
shorter then others. My question is; does one cut the rib on TE or LE,
or both evenly?
