Removed the F-706 bulkhead from the aft fuselage and began deburring holes for longeron and where the aft and center fuselage meet. Since there are so many holes, I only did part and left myself notes on the plastic as to which holes had been deburred.
Decided to make the aft baggage panel removable, since the forward one is removable per plans and I made the baggage floors removable. Opened the rivet holes in the F-706 bulkhead for screws, used the nutplate drilling jig to drill mounting holes, deburred, then dimpled the rivet and screw holes. Will use countersunk screws here as this panel mounts behind the aft baggage wall.
