Brief Description: Flaps - Squeezed row of hinge rivets
Then I riveted the hinge, spar and bottom skin. I squeezed these rivets. Worked great. No issues. I riveted the outboard rib with the squeezer. One departure from the drawing was I used -4 length rivets instead of -3.5 for the three holes that rivet both skins and spacer. It was a more proper fit. The -3.5 length was too short.
I squeezed the very trailing edge rivets with a special yoke I ground down during the empennage build.
