In order to get a good alignment of the trailing edges, I set up a string line, and while there was still movement of the framework with only the top skin fixed, I set the alignment before the drilling of the bottom skins in the tailing edge area.
This is important due to the washout that has been built into the wing, and the trailing edges are not naturally in alignment.
After the skin had been drilled & clekos installed, the alignment was set in place and no further movement was possible.
