I wasn't happy with several rivets after riveting yesterday, but was too hot and called it a day. Today I had a close look and decided that most of the top enging mounting bracket rivets needed to be replaced, so I just replaced the lot. I also replaced some on the cross pieces and uprights that were too close to the platenuts, because I didn't figure out beforehand to rivet to the firewall first and then rivet the platenuts afterward. There are two that I still don't like, and I'll do them tomorrow, after I've been flying. I had primed the contact surfaces of the cross pieces and the uprights, and thought that I should've primed all of them. So I ended up priming the cabin side, I think it looks quite pretty.
