Riveted on the control arm brackets on both spars. Everything is hand squeezed because I sold the rivet gun a couple of years ago when I finished the RV-7A. By the time you get to the 25th AD4 rivet, you're pretty much out of gas when it comes to hand strength.
Also clecoed the spar box back together and realized I failed to countersink two holes on the forward spar so did that.
I didn't rivet the CS-4 rivets because I wanted some time to think about what I'm doing to make sure I'm following the instructions correctly. This happens a lot.
I also added nutplates to hinge brackets and separated some other items from a long strip.
