Tonight I riveted the inboard rib, tip ribs, and spar doublers to the left elevator main spar.
I started with the tip ribs, which require 4 universal head 4-4 rivets. I was able to squeeze 2 of them, but the two running parallel to the ribs needed to be bucked with a double offset rivet set. Then I squished the doubler rivets, and finally the inboard rib.
