Lori and I finished riveting left wing top skin and I attached the outboard aileron hinge. Thats one side done. Set up left tank skin in cradle, drilled and deburred J channel, celco'd tank baffle in and did countersinks, then got about 80% of the skin dimpled before I got tired and the hammer slipped. Dent not too bad but noticeable enough that I'm going to replace it.. There's another $230 sent off to Van's for replacement parts.
