The crescent shaped ply part on the rear cockpit bulkhead performs the twin duties of tying the two former halves together, and providing an edge to which the canopy can be glued.
The canopy frame is built up in place, with the starboard rail first being hinged up with brass doll's house hinges

The hinges are supported in the wing with 9mm dowel, and the hinge knuckle set back in the aileron to allow for correct rotation. The servo is mounted on 3 x 6mm spruce rails...
