Brief Description: Beginning of Right Hand Wing Box Assembly.
Using an ultra fine blue sharpie I marked a line along the center of the top and bottom flange of forward & aft Ribs #1 - #12 for RH wing half. Then I clecoed them to the Main and Rear Spars. Next I blue lined and installed RH forward & aft Root Ribs. Then I established and locked in the Rear Spar Attach Hole location ( at station 19.0 in ) using C-Clamps and an adjustable bar attached at station 0.00 in Main Spar and Rear Spar Attach Hole respectively.
Aft Ribs Clecoed to RH Main Spar & Rear Spar.
Establishing Rear Spar Attach Hole location ---19" from Wing Station 0.00.
Rear Spar Attach Hole Locked into Position with C-Clamps.
