Finished drilling to final size the main ribs and leading edge ribs to spar. I numbered all ribs 1R to 14 R starting at wing tip rib. While drilling to fial size, I messed up the main rib trailing edge flange of #12R. I only had 1 clecoe holding the flange. The flange was slightly off 90 deg so when I drilled the holes , they were off as well.. I later ended up fixing this by adding a doubler angle which will reinforce that area. I will need to increase rivet length here. I'll show a picture of this later on when I assemble the primed ribs back onto the spars for riveting
