Time now to make a start on the wings...The preliminary jigs take care of the gull bend; later, an entirely different set of jigs will set the wing up without any unwanted twists. The main spars are 5mm sq spruce, with some of the tension steamed out at the gull change...

With the dihedral check safely passed, the brass boxes (one 13mm, one 15mm) can be epoxied in and closed off. Then it's time to fit the sub spars in front of the web plates...

With the lower sheeting added in two sections, preparations are made before adding the top sheeting, which will be in three parts. The centre sheeting spans the gull break and is forced into a compound curve to preserve a smooth transition around the bend...

The most critical part of the wing construction: adding the top sheeting locks the wing into its final shape...

We usually cut a hole in the wing root, on the field, just before the maiden.
