Brief Description: Drilled Stringers/Ribs to Aft Forward Skin
4.5 6/26/08-Double-checked centerline on F-6112. Drew another centerline on top, as well as bottom side. Cut off a length of particle board to clamp against bulkhead F-606. Drilled screw holes in particle board to match the nutplates in the bulkhead. Cut out holes in board to reach thru for drilling. Clamped board to bulkhead F-607. Positioned forward top skin in place and put strap loosely around skin and fuselage. Used hole duplicator to drill six holes on skin along bulkhead F-607 and a hole in rib F-687. I reached under the skin while Dad held a block of wood against the skin. I back-drilled part of the rib and the right stringer to the skin.
