After so much painting, I wanted to get back to basic drilling and riveting. I accomplished the final install of the battery tray by riveting and bolting it to the firewall. Getting the AN5 bolts to fit the bottom of the battery tray was quite the adventure because one of the rivets on each side interfered with the bolt fitting in. This appears to be a design flaw. Mark helped me buck the rivets here. Then, I installed the nut plates on some of the angles that hold the forward baggage compartment walls. I then riveted on one of the angles to the forward fuselage skin.
