Mid-fuselage bulkheads started

The fuselage starts with the center bulkhead, doing lots of drilling:

Forward center section bulkhead parts match-drilled
then also drilling into the steel landing gear mounts:

I had to significantly enlarge some holes for snap bushings where the rudder cables run  (it looks too close to the edge, but it's what Van's says to do...):

Snap bushing holes on center and side forward center bulkheads
and finally, a bunch of countersinking for flush rivets and screws:

This was only the first part (the center section) and there are 3 more (the other half of the center section, the rear spar bulkhead and the fuselage bulkhead), so there's still a lot more drilling and countersinking to do.

Time lapse:


Total mid-fuselage bulkhead rivets: 0
Total mid-fuselage bulkhead time: 8.8h
