Fabricated stiffeners, deburred. Installed stiffener overlapping exising inboard stiffener (line at 5/16 on both stiffeners). Flush stiffener on the last rib (checked right angle). Clecoed bottom outboard wing skin overlapping existing bottom inboard wing skin. Final drilled #40 all skin holes and drilled the J stiffener along the line.
Final drilled the holes for the nutplates with @19 drill.
Disassembled all the parts, deburred all the holes and dimpled all the skin and stiffeners holes.
Started dimpling the rear spar, however after brief consultation with Lucio we decided to countersink the rear spar preparing little jigs to avoid countersink pilot to wander and ruin the hole.
