Prepped bottom wing skins for priming - 7 hours

Very long day today working on the wing skins. I began filing all the edges on the skins down to remove the shear marks. Next I rounded all the 90 deg corners. Then I 3M'd the edges so they were smooth as silk. Next I deburred all of the holes, both sides. Once that was done, I then made/filed the scarf joint on the two skins that overlap. Next I used the edge rolling tool to put a nice edge on the leading edge of the skins, and the edge that overlaps the other wing skin. Next step I countersunk the holes for the rivets that hold the access plate nutplates on. Last step of all was to dimple the holes.

Very long and tedious day in the garage....but its done.
