Wing Jig Set-up
:
(continued)
3.
Set the plywood washout cradle assemblies on the aluminum jig brackets, at each end of the wing jig. Run the bolt through the center of each cradle and screw on the wing nut only enough to retain the bolt from falling out.
Remember that the washout is negative 3-degrees at the tip; so the trailing edge of the tip is angled up, and the leading edge is angled down.
4. Align the wing ribs in mirror images so there is one left, and one right, wing panel. Ensure that the ribs are clustered in ascending/descending order such that the root rib (W1) is at the same end as the straight cradle, and the tip rib (either W10 or W10a, depending on the version being built) is at the same end as the angled cradle.
5.
If CF rods are being used, sand a bevel into each end of the rod to eliminate burrs and ease sliding of the ribs onto the rods.
