Clamped and drilled Nose reinforcement plates (T-410) to both the Inboard and Outboard Ribs.
Match drilled holes in T-408 and T-407. Dimpled Inboard Rib for T-407. C/S T-407 for rib dimples (-.007 to -.008 below flush). Riveted T-407 to rib.
Opened up fuel cap hole with scotchbrite wheel until cap just fit into hole. Then used reamer to size all holes.
Match drilled Fuel Drain VA-112 to skin. Kept rivets in line fore/aft for better aerodynamics... Lol. Not much to be gained since big flange of drain sticks out. Used end of Sharpie to align prepunched hole with hole in drain.
