Started out by dimpling, cleaning and priming the left aileron stiffeners and skin. (Also primed the tailwheel fork.)
I made some supports for the rear wing spar to help steady the wing during riveting.
I got half of the stiffeners back riveted onto the aileron skin.
Britt and I spent about 1.7 hours riveting the inboard top skin for the left wing. The long offset rivet set is still tricky but I'm getting more comfortable with it.
