Began today by setting up T-407 reinforcing ring and nut plates for riveting to T-403 end rib on right fuel tank. Checked reference pictures from Kent's RV-7A build to see if he used sealant here (plans say no sealant) and noticed I was missing the hole for the fuel tank vent line. Disassembled T-407, consulted plans, and used the step drill to drill holes in left and right fuel tank end ribs for the vent line fittings. Re-assembledT-407 and nut plates with clecos. Used the squeezer to set the rivets, alternated across the circle as I went along. Repeated process for left tank end rib.
