Today I was able to mark the ribs, and their location to the rear spar. I made a template to keep the spacing the same on all ribs, other than the inboard 4, which are on a different pattern. I piloted the rear spar, and then clamped it back to the ribs. Sure enough, my line was visible behind every hole, right on center. As shown in picture 3, all ribs are drilled and clamped to both spars. Now I am ready to get the leading edge ribs on, and then take everything apart to deburr and prime. It is nice to see some good visual progress today.
