Today I had a marathon session that pretty much repeated the closing of the left tank (see 9-1-12). You'd think I'd have learned to speed up the process... The only real differences were that I'd already scuffed and cleaned the baffle, but had not installed the fuel pickup.
I didn't rivet the end ribs to the baffle and brackets, as it was waaaaay too late to run the rivet gun when I got to that point.
