Reassembled the bottom skin back on to the skeleton. Added the bellcrank channel cross braces and the skin stiffeners. Spent about 20 minutes getting the level just right by leveling the front spanwise, tipping the rear edge up/down so the main spar tilts at a 9 degree angle, from vertical, then leveling the rear channel. This is done to ensure there's no twist at all in the wing and so it will fit correctly when the main spar is inserted into the fuselage when the wings are mounted.
Once leveled, it was a straightforward process of filling all the rivet holes (between the cleco clamps) with rivets, firing up the compressor, and riveting ... over 425 rivets - all of them good ones.
The leveled wing, skin clecoed to the sketeton, and rivets inserted and ready to pull.
