Today I drilled out and attached the rear channel to all 9 rear ribs. I then attached all 7 nose ribs to the wing spar. It was a lot of measuring, re-measuring, clamping, duct-taping, drilling, and clecoing, but the work was steady progress with no errors. It almost looks like a wing, doesn't it?
The rear channel with the rear ribs clecoed in place.
A view down the main spar. The large gap in nose ribs is where the long-range fuel tank goes.
The obligatory shot through the forward lightening hole down through all the rear ribs,
