Karl and I finished top wing skins. Total of 6 bad rivets which I drilled out. There were also some places along the rear spar near the aileron and flap brackets that neither the squeezer nor the bucking bar could get. I installed MK-319-BS rivets instead. (Grip is 0.125", and the skin + various doubler plates is ~0.110").
Will replace the other drilled out rivets tomorrow.
