This session was planned to get the right wing ribs riveted to the spart. After a bit of confusion over which rib went where, I got everything arranged and clecoed in place. When Steve got there, we had to drill and deburr a few holes, then we started riveting. I shot, he bucked...he's getting pretty good at this!! The actual riveting only took about an hour. Next up...rivet the aft spar and hang the wing in the stand.
