Today I was able to get a full day in. I spent the day disassembling each rib/shim pair and deburred, scuffed, and primed each one. I'm not reattaching anything to the main spar, as I need to go back and drill out the holes for the wing strut. I should be able to get most of that complete today. I also need to add the modification to strengthen the aft outboard rib attachment.
