Continuing where I left off yesterday, both with the riveting and the heat, I finished up riveting the ribs to the main spar of the right wing, and then moved onto the rear spars. The remainder of the riveting to the main spar went without a hitch.Switching to the rear spars, I started by closely studying the plans to see the rivet callouts and which holes should be left empty because they get attached to other parts like the flap brace and aileron gap fairing later. I put masking tape over these holes to remind myself not to rivet them.
I then got the longeron yoke in the squeezer and got to work. Most of the rivets are -4 length rivets so I set all of those on both wings, then stepped up to the ones needing -5 and -6 and so on. The longeron yoke is able to reach all the rivets on the rear spar because it can reach around the flanges. Finally, I did the flush rivets that attach the tip ribs to the spar and then the work was done!

I need to next build wing stands to hold these in place for the next steps!
