Before all of the ribs were set with epoxy, I needed to make one rib a reference point. It had to be aligned with the spar and level. It also had to be square with the reference line on the spar. I ran a piece of angle aluminum through the spar and attached it to the center line of the rib. This gave me a straight rib that was easy to level. This was also done to the first rib on the left side of the wing. Both ribs had to be square and level. This process took quite a few days.
