I used the flexible bit to drill the aft most holes in the center stiffeners.
Then I also rounded the corner I had made in the cut out on the front end of the center two stiffeners.
Now as I look and contemplate the status of this forward fuselage I am awakened to the objective that every hole must be drilled to final size before I start taking things apart. So before moving aft to the bagage area I'm going to do all the little pick ups that are on my mind and on the drawings for this forward fuselage area.
