Worked on RH side this morning (up at 5am). Riveted the inboard (root) ribs to the front spar per plans. Started riveting the center nose rib on the RH skin. Went well except for the forward most rivet on the bottom skin, the rib flange drooped down and I couldn't keep it pulled up tight to the skin for riveting. I will get some very small o-rings today and see if the trick works, whereby you slip a o-ring onto the rivet shank to pull everything tight and then you buck the rivet and the o-ring pops off or splits off. Good progress though.

center nose rib almost riveted onto the RH skin - top is done and this bottom skin only needs 1 rivet
