i got in a full day of building today. for the first time in the project, i drilled out a bunch of rivets i wasn't happy with. i think the firewall was flexing as i backriveted and leaving some of the heads standing a little to proud for me, so i drilled then out and then put in another rivet and made sure it was flush. i was able to use the squeezer on a lot of the edge ones which helped.
