Did a bunch of cleaning work at the hangar because Heather (family friend) was to stop by and bring stuff for me to store until she and her boyfriend find a new place. But she had to take her cat to the vet so I cleaned up stuff anyway. Then I deburred the doubler plates and primed them, and then added the 10 rivets in the "triangle " cuthout and clecoed everything back together. I'll start riveting tomorrow. Maybe.
