- Fixed rivets in Left Center Ribs (HS-404 to 702 to 405). - Riveted on middle nose rib to skin (HS-707 to 601). - Clecoed in outboard rib and middle rib (HS-706 & 708 to 601 skin) in order to rivet bottom of middle nose rib. - Removed middle rib (HS-708) and clecoed in front HS spar assembly and replaced middle rib. - Blind riveted middle ribs, nose and support to front spar (HS-707 to 702 to 708). - Riveted outboard ribs to front spar. - Riveted skin to front HS spar and middle ribs (HS-601 to 702 and 708). - REPEATED THE ABOVE STEPS ON OPPOSITE SIDE - Put Rear HS spar on to rivet remaining ribs (HS-404, 405 and 706); outboard and inboard. - Riveted all ribs to skin, save for fearing attach points on the top inboard ribs. - Removed rear spar for inspection and primer touch-up. - Touched-up the few scuffs created by the bucking bar during riveting. - Prepped and primed exposed portion of the skins (strips where plastic was removed for dimpling and riveting). There were some areas where the ALCAD was scrapped off and I wanted to protect the metal until final paint.
