Got the templates done a while back, and a stash of blank balsa pieces squared up on two side.
That gives me a flat side and end to line up the rib template and the blank balsa, and do a bit of cutting
Some time later I end up with the inner and outer panel ribs for both sides.
All good, and with a bit of clean up I could get the panel build started.
These are E385 ribs app, 7 inch Chord, for a 100 inch Wing Retro plane
