The cabane assembly is pretty straightfoward. I like to use MDF for my wood jigs because it's smooth surface takes marks easily, and it is nice to work with. A threaded rod is used to locate the cabane bushings in their proper place. The top wing angle of incidence is created by the location of the bushings, so precision is important. The jig rests at right angles on top of the longerons so fore and aft location is easy. The jigs centerline is placed at the fuselage centerline, and the angle of incidence is set by measurement, rather than protractor. Holes are then drilled for the threaded rod and the bushings are secured to it with jamb nuts. It then becomes a simple job to fit the streamlined tubing to the bushings and the fuselage.
Reinforcing wrappers are then added to the joints and formed around the fuselage. One diagonal leg is made to be removeable, to facilitate installation of the fuel tank in the front bay.
