I drilled the right wing frame and skins to final size, I had also clecoed the flap strengthener and the aileron gap panels to the wings rear spar, and drilled them at the same time. I drilled one set of holes, then moved all the clecos over one hole and then finished drilling. That's a lot of clecos! I ringed each cleco with a pen when in it's first position so that I didn't lose track and miss some rivet holes.
