As always after a long break, I spent half of my time figuring out where I was and the other half looking for tools. I riveted the platenuts to the battery box and temporarily bolted it into place. I fabricated the F-7127D plate, primed, and riveted it to the firewall. The picture below makes it appear extremely crooked but thankfully, it's just the camera angle. I need to locate the copper bar in my pile of plane parts and I can install the battery and starter contactors.
