❏ 8. Glue former 3A to the front of 3B. Glue the die-cut
1/16" [1.6mm] plywood doublers 2C to both sides of
former 2B. If you will be installing retractable landing gear, drill 9/64" [3.6mm] holes through the two other punchmarks for the nose steering guide tubes.
❏ 9. Use a straightedge and a fine-point ballpoint
pen to draw a line across the punchmarks in one of the die-cut 1/8" [3.2mm] plywood fuselage doublers. Enlarge the notches in the doubler back to the line by cutting away the unused material. This will now be the right fuselage doubler.
❏ 10. Cut one of the shaped 1/4" x 3/8" x 36" [6.4 x 9.5 x 910mm] balsa fuselage main spars in half. Splice one of the halves onto another fuselage main spar. Hint: Pin the spars to the building board along the borderline of the plan to make sure they are straight. Make another assembly the same way.
❏ 11. Pin the fuselage main spars to the building
board over the plan as shown in the sketch. Note that the aft ends of the spars align with the front edge of F10B. The front of the spars should extend slightly past the front of the firewall (for trimming later). Also note that the T-pins should go in at an angle so as not to interfere with the fuselage doublers when they are added later.
❏ 12. Drill 3/16" [4.8mm] holes through the
punchmarks in formers 9B, 8B, 7B and 6B. Drill 1/8" [3.2mm] holes through the bottom two punchmarks on both sides of former 2B.
