Today, I spent the morning match drilling the nose ribs. It's the best I've done to date, with all the holes on the centerline. In addition, I spent quite a bit of time scuffing each rib and prepping it for priming. This afternoon, I removed the plastic from main ribs, marked them to trim to the proper length -- 12 3/8", and then cut them. Tomorrow, I'll work to match drill the main ribs and then rivet the entire assembly.
