Before I can start assembling the wing, three ribs (W4, W5 & W6) which support the retracts, must be reinforced by epoxying 1/16" plywood rib doublers to their sides.
Before the epoxy is spread, I like to hinge the doublers with blue painter's tape. This creates a hinge which aids in alignment when the epoxy is applied.
