Left Wing Ribs Riveted

Tad and I got the Left Wing ribs riveted onto the both front and rear spars. We left the outboard most rib off as per the instructions.
We had a couple of rivets we weren't happy with but they were fairly painless to remove. just time consuming really.
We used the 4x gun and reduced the pressure to around 50psi i believe. That gave Tad a bit more control of the impact. anything higher and they seemed to set too fast, either they were under or they would be over with only one hit.
The Rear Spar was easy to do with the pneumatic squeezer and only had one that didn't squeeze straight - the very first one we did. It was more from the inability to see the rivet properly but flipping over the wing allowed much better control of it.
Oh, one last thing, we ended up drilling out one of the tooling holes just in case we decide to install a AOA device later on in the build. I think it was a good idea to do that.
