Aft Fuselage ( 3 hrs )
Nancy again helped finish rivets along 3 bulkheads for LH Top Skin.
Then I started RH Top Skin prep by deburring all holes, and edges (sanded first with 180, then 400 grit. For some of the rougher edges, I use a large file to smooth first ). Also rolled edges (ie "break" edges to insure lay tight onto overlapped skin.
