I started to rivet the trim tab today. Because I chose to use the riblet method and face the flanges inboard, I have to use blind rivets on them. Got to the hangar thinking I had the right ones, but I didn’t so I had to order a few.

Riveting the tab’s spar to the bottom skin looked like it was going to be a challenge, but using the longeron yoke worked perfectly. I ended up having to buck a couple of the trim tab horn’s rivets, but they came out really nice.
