Rud: Priming, Riveting
–Primed stiffeners
–Riveted stiffeners to left skin
I used Tempo Zinc Chromate on the stiffeners because I couldn’t find any self-etch locally. I does not seem to adhere well at all compared with the 7220. It’s good enough for these stiffeners but I won’t be using it again.
The first few rivets for the left skin stiffeners were poorly driven because I couldn’t get the back rivet set to fit well against the stiffener flanges. I ground down the plastic on the back rivet set to get clearance against the stiffeners. After this the riveting work much better.
