The same process is carried out with the top leading edge sheeting piece:
1) Turn the wing back over again. Press it down, evenly against the building surface, and tack glue it to the front 1/8" of the top main spar.
2) Turn the wing up-side down again, and run thin CA along ribs where they contact the sheeting. I started close to the spar for each rib, applying a little CA, and "rolling" the wing forward (which lifts the trailing edge off of the table, but keeps even pressure against the curvature of the airfoil of each of the ribs and sheeting until the glue sets.
When set, I ran more thin CA along the remaining front section of each rib, rolling the panel further, and then along the leading edge doubler,
