Cleko'd the leading edge (LE) assembly onto the main spar. Will need to get a partner to help rivet the LE rib rear flanges to the spar.
Worked the top-inboard skin. Removed the blue plastic of death from the rivet lines on the outside of the skin, and removed all the plastic from the inside. Deburred all of the holes and edges. Edge-rolled the leading edge of the skin so it lays nice and flat once riveting it on the spar. Dimpled all the holes.
