Establishing Zero Twist In The Wing

Take a cleco with some fishing line and a plumb bob and drop it down from the ends of the main spar. Now measure the distance from the line to the rear spar. Once you establish the same distance on each end, clamp down the rear spar. See the plumb bob hanging down,left of the brace?

When it was time to put the bottom skins in place, I hammered a nail through one of the existing holes, in the rear spar, to the bottom support. I was now free to remove the quick clamp that was interfering with the skin placement.
