Installed an over-sized "oops" rivet (NAS1097) into the LH horizontal at the junction of 708(center rib) 707 (center nose rib) 702 (front spar) and 801PP (skin). Worked perfect and you would never know its there. Used an o ring on the rivet shank to keep the flange of 708 flush with the skin. Moved over to the RH horizontal center nose rib to get the forward most rivet installed - very tight quarters and I should have done this rivet first so I would have more room to move to spread the skin apart for bucking. Rivet didn't come out that great, but in such a tight area I doubt a second attempt would be any better. I have seen guys blind rivet this rib for that reason so I can always do that later if I change my mind. I riveted the end rib (706) to the end of the front spar (702) - 2 rivets. Blind riveted the center rib (708) to center nose rib (707) to front spar (702) internally per the plans - these rivets are covered by the skins. I'm ready to do the RH skins next session.
Riveting the front rivet on the RH center nose rib - tight quarters. Note o ring, use tubing next time
Riveting the end rib to front spar
Getting there - hope to have HS done by week's end
