I've been waiting for at least a slight bump in temps so I could prime the stringers and get back to building. Today it jumped up to 40, so I figured I'd give priming a shot. While it worked, the cold temperature really does make for lousy priming. I got it done, but the coverage is very inconsistent, from minimal to super thick. I think it's simply because at the low temps the water in the primer doesn't flash off like it does in warmer temperatures. But it's done, so that means I can finally get back to riveting!
I started my riveting session with the bellcrank rib (the bottom one - the vertical one stays clecoed for now). I figured I may as well rivet the rib to the bottom skin before the side skins go on. That made it possible to do by myself, whereas with the side skins on I would have needed help to reach.
After riveting the bellcrank rib, I got to see how tough the Rustoleum primer is, or isn't. The vibration of the riveting literally made chips fly off of the pieces. I touched it up, so it's fine, but boy does it look bad! I keep having to remind myself that it's still better than nothing, regardless of what it looks like.
The very aft bottom skin and bulkheads were next. The extreme curve of the skin, coupled with its thickness, kind of makes it tough to set good rivets. I got the most aft bulkhead riveted before ending for the day.
