Prepping main wing skins

For the last few days, I've been taking care of the steps to get this main wing skins ready for riveting.  It's nice to have the skeletons of both wings assembled, and installed in the wing stand.  I clecoed the top skins to both wings, and match drilled all of the holes.  Once that was finished, I repeated the process for the bottom skins.  There are a lot of holes, but it seems to take longer to to move the clecoes than it takes to drill the holes.  With all of the holes match drilled, the skins were removed from the skeleton, the blue vinyl was removed from the rivet lines, and the holes were deburred on both sides with a speed deburr tool.  The next steps will be to deburr all of the skin edges and dimple all of the holes.
