Rivet Aileron Stop and End angle before torquing the rod end to the Aileron. Cleco using a pattern: Main Spar middle out (every othe hole), Nose ribs from the spar forward (cleco every hole), Wing ribs from main spar back (every other hole), Rear Spar middle out (every other hole).
When riveting the nose ribs I removed one line of clecoes along the length of the wing, then used middle out pattern. Repeat one line of clecoes at a time working towards the leading edge.
