Removed the F821 top front skin. Back in December when installing the F803c flange to the instrument sub-panels, instructions have you leave the center 8 holes open for any minor adjustments when fitting the top forward skin. I used the pneumatic squeezer to set these remaining rivets. Reamed the holes along the sides of the F821 skin to #41, and about 7 of the holes on the left front to #30. Deburred all the holes on the inside of the skin.
