Wing Jig Set-up: (Continued)

7. Place the jig over the plans on an appropriate warp-free building surface.

8. Place the rods in the washout cradles, ensure the rods are centered in the jig and loosely snug the wing nuts. Sight along the rods and the wood base pieces to ensure that the wing assembly will be square to the wing jig. Double-check to ensure the jig itself (aluminum brackets to the wood base rails) is still “square.”


In the first two pictures, note that the CF rods run parallel to the wood base rails of the jig, and the entire assembly remains "square." Picture 3 shows the 3-degree negative washout of the cradle at the tip.

9. Align the inside edge of the aluminum bracket of the jig with the plans. More specifically, the bracket near root rib W1 should be aligned with the center section of the wing plan.


Note that rib W1 is slid out of the way, the aluminum bracket is aligned with the wing center, and rib W2 is lined up over its position on the plans.

10. Gently slide the ribs apart. Align W2 with its location on the plans. Move W1 further away from W2 (over the aluminum jig bracket), and the other ribs to generally be just outside of their location shown on the plans.
