Today I began riveting the bottom skins to the right wing. I started with the rivets to the rear spar. The worst ones have been the ones where I have to get my hand between the inboard 4 ribs that go under the wing walk. My hands are so big it is tough to get them in there. Now that I have worked my way outboard a few rivets it gets easier to get to them but now the tough part is reaching all the way up there. It is a good thing I have long arms!
