Riveted the nose ribs and hinges together, then installed onto the spar. Riveted all main ribs to the spar and cleco'd the top skin, and nose skins in place. As with the L. side, I re-purposed saddles i made for the "Horizontal Stabilizer" to hold the flap for riveting. Rived the nose / top skin to spar, and the mian ribs while it was held vertical in the saddles.
