I'm trying to go back and get everything caught up. I've been skipping around to get priming done in batch jobs. It's worked for the most part but I missed a few things. I finished F704 except for riveting the uprights. I'll do that when it comes time to start assembling the forward fuselage. It's harder to store with everything riveted on and I need all the space I can get. I went back to take care of the firewall. I worked out a strategy to get the dimples and countersinks right by putting tape all over the parts and marking what needs which sized dimple or countersink. The fireall is assembled with flush rivets on the front side so it is easier to clean and add other stuff to the engine-side (battery trays, bus bars, etc...).

Same strategy for the stiffners...label everything
