Brief Description: Marked rib locations and other markings in new sp
I had to redo the centerline and spar markings on the new spars I purchased for the upper wing. There are four spars: (2) rear spars and (2) front spars. This work that I did will be used for reference when the ribs are added after the spars are joined.
Once one of the spars is laid out for the ribs, the markings are transposed to the other 3 spars.
