Measuring wing twist

Everything was ready to put on the outer wings and measure the twist. I can see that without rivets, the inner wing can be twisted a little bit. I measure the leading edge and the trailing edge with a reference to the laser level light. If the difference is the same for both wings, it should be straight. It looks fairly straight, but if I twist it, it will stain in a new position, about 3-5 mm off. This is with clecos on the trailing edge. Two holes on the main rib, one towards the fuselage and one towards the outer wing, will hold the twist. Just a bit fiddling and it will hopefully be straight. It is very straight, but I will try to do it as good as possible, and hold it in place with support fixture.
