Most builders leave the fuselage upside down to rivet the side skins. I felt there was no reason to do this as I can solo rivet most of it with it right side up. I had Marsha help me roll it over and I started riveting. I solo riveted the armrests, F-905 bulkhead then added the baggage bulkheads and riveted those. Riveted the longeron in the areas necessary. Tomorrow will be the aft to forward side skin seam.
