Dimpled the vertical stabilizer skin. Had a couple of goofs when dimpling the middle nose rib holes. The sheet popped off the dimple die before I hit the upper die, and punched a hole in the sheet (and dimpled it) next to one of the holes. On the hole before that, the sheet must have almost popped off, the top of the male die punched out a small piece of skin, elongating the existing hole.
