While I had the F-706 bulkhead out of the fuselage I decided to make the optional hole for the static line on the left side symmetrical on the right side. Did the layout for the hole and drilled with a step drill. Deburred hole and scuffed with scotchbrite. Also used the step drill to open a tooling hole in the F-710 bulkhead to allow for an alternate path for the tail wiring. Deburred and scuffed this hole as well.
Completed the deburring of all the holes inside and outside the aft fuselage. Lightly scuffed the holes. Ran the vacuum through the whole aft fuselage to clean out all the chips and swarf. Dimpled the aft fuselage skins with the squeezer. Reinstalled the F-706 bulkhead.
