I was only able to work a couple of hours today -- multiple errands and a bit sick. Hopefully medicine will kick in and I'll be better for the riveting job on Saturday.
I spent some time looking ahead to the wing tip installation and installed the extra ribs per that chapter while they were easy to get to. Then I disassembled the outboard rib assembly, primed and riveted the stiffeners back on, leaving the wing tip stiffeners for later.
Near the end of the day, the UPS man brought my rivets -- so, tomorrow I plan to rivet the entire assembly together.
