Yesterday and today I finished reinforcing seven aft ribs. Also potted in the aft shear webs. Because of some timing issues, I decided to form all micro radii on the aft ribs at once, for later sanding. That's a departure from the prior plan, but is ok, as I'm forming the radii very carefully, removing as much excess as possible, so subsequent sanding is minimal. I also cut all bid necessary for the remaining aft ribs and shear web.
