Trailing edge finished!

Double-flush rivets

I used Van’s recommended procedure for setting the trailing-edge rivets, with a few exceptions. First, I used the pneumatic squeezer to initially set rivets in the sequence recommended by the manual. Then I used the back-rivet set to get the shop heads parallel with the trailing edge. And finally, I used a swivel flush set on the manufactured side make each shop head as flush as possible with the skin. The last two steps were done to groups of four or five rivets at a time – hit one side with the back-rivet set, then flip the rudder and finish up with the flush set.

And the result? The trailing edge was straight to within 0.04 inches, which beats Van’s requirement of 0.1″. If you sight down the edge you’ll see some very minor pillowing or waves in the edge, but overall I’m satisfied. And there was much rejoicing. Yea.
