Here are pictures of the 2nd bracket, with adel clamps to hold the AN fittings connecting the pitot and AOA ystem parts.
Then I got back to riveting the main ribs to the main spar. I got 7 done today.
The instructions say to cleco the rear spar on before riveting, but there's no reason to, and it just gets in the way. Leave the rear spar until after you finish the main spar, then you can get your body between the ribs to better rivet.
