Worked on the bottom left inboard skin. I dimpled the skin as glen squeezed the ribs. I messed up a hole as I was hitting with the hammer the skin jumped and I missed the hole and ended up with a hole about an 1/8" away. glen saved the day by flattened out the dimple hole and then inserting a rivet then grinding it down and redoing the hole and dimple. see picture 2, can't even tell it was repaired unless you look real close.
