Tonight I prepared more of the skeleton for riveting. You know the drill, debur, smooth the edges, scuff the surface for priming, dimple, clean the part with mineral spirits and then prime. Tonight, I prepped the seat ribs, the baggage ribs and the bulkheads surrounding the cockpit. Some of the rivet holes in the side of the fuselage had to be countersunk instead of dimpled since the rib was backed up by an aluminum angle doubler, which prevented me from dimpling. I also discovered that some more of the side skins had been dimpled in places where a universal head rivet was supposed to go instead of a flush head rivet. Therefore, I had to squeeze the dimple down and flatten the skin there. A couple of more nights and I should have the fuselage skeleton prep finished.
