Over the last month and a half I’ve been alternating between the wings and fuselage. We’re working our way outboard on the left wing’s lower skin. I tried for a really artsy photo here, but don’t think I got it.

Artsy, huh?

With the skins riveted in place around the pitot mast opening, I test-fitted the mast. Turns out the skin expanded outward a little bit during riveting, so I had to tweak the holes a little bit to get everything to line up. Came out ok…

Almost done with the outboard skin…
