Fitted all of the rear spar reinforcement plates. Drilled, deburred, primed a few of them, and riveted them together.
And loads of ribs to deburr, true the flanges to 90°, and flute the curves out. Kind of tedious.
Hoping my motivation will be rewarded, today I bolted up the tie down brackets and bell crank brackets to the main spar. I also deburred the rear spars and associated parts.
