21-6: Step 2: Riveted the Left Aileron top skin per the instructions. Used short one inch square tungsten bucking bar with a small wedge on the bottom to set the driving angle parallel. This worked somewhat but ended up using the longer tungsten bar and the angled end to finish bucking rivets. All in all, they came out ok. I riveted every other hole beginning in the middle and working my way out to each end alternating sides as I went along. Clecoed all holes of the bottom skin after finishing and intend to begin in the middle and work my way out again removing clecos as I go.
