Brief Description: R fuel tank (Inboard rib modifications)
Removed the inboard rib to modify for access cover plate. I made a paper "Target" on the CAD program to accurately locate the access plate cutout. Used the CNC router to cut the 5 1/4" hole in the end rib. Drilled the end rib for screw holes and platenuts. Riveted the platenuts. Fabricated the vent line mount and preped the fuel filler and drain valve mounts. Time to disassemble and prepare ribs and skin for final assembly.
