Using DuPont 211S spray can primer, touched up spots on ribs and spars. Using pneumatic squeezer, riveted the ends of HS-610 and 614 angles to HS-602 spar channels. Using a rivet gun, riveted the center sections of the angles and spar channels together. Had to drill out 6 rivets in center section. Riveted the right HS-608 rib to the rear spar using the pneumatic squeezer, but had to drill out both rivets. Had left rear spar in the jig while attempting to rivet, but it didn't work well. Removed rear spar from jig.
