After I got the fuselage all level and square, I proceeded to trim, fit and drill the rear deck and F-609 bulkhead.
I cut out the access/lightening holes in the rear deck per the plans and made the notches to fit around the stab attachment bars. I then marked and predrilled the rear deck for the rivets that will attach it to the longerons. I also drilled the rear deck forward flange to the F-609 bulkhead. The rear deck won't be riveted on for quite a while so I have access to the rear part of the fuselage, but it needs to at least be clecoed in place so I can fit the top skins. Before drilling I re-checked that there was no twist in the fuselage just to be sure.
