Primed rear spars. Riveted left rear spar
Today I finished drilling the left rear spar. Then I countersunk/dimpled the holes in the spar flanges. Afterwards I primed all the rear spar pieces. Once the primer dried I started riveting on the rear spars. I was able to get the left one complete. Tomorrow I should be able to wrap up the right one.
The rear spars and their pieces all primed

Left spar all done. Next up will be the top skins. It's starting to look like a wing!
