More riveting bottom left inboard wing skin - 4 hours

Slowly i've worked my way riveting. All along the rear spar for one bay, then up one rib towards the spar, then along the spar to the next rib. Then repeat. Ive used a string to hold up the skin to allow me to reach in. By the end of the evening I was done the skin. Took me much longer then it seems to take everyone else, but ultimately I am very happy with the results.
