Installed the AN-3 bolts and cherry rivets that fasten the ribs to the main spar for both wings today.
Riveted most of the ribs to the rear spar for the right wing. The other ribs and the rear spar stiffener will be fastened after the ribs and spars have been drilled and dimpled.
Ran out of BSPS-42 rivets, so the left wing rear spar attachment is temporarily on hold.
