Time to hook up the controls. But wait. Imagine installing a bulkhead in a flap that’s close to a foot down a tapering shell. And to top it off the inboard hinge is in the way so sliding the bulkhead down the inside of the flap is not possible. Just one more nearly impossible task on this 3W shell.

First picture shows the special tool kit it took to get it done. The wood dowel has a pencil lead on one end and wood screw threads on the other. I could just jam the bulkhead in around the hinge enough to screw the dowel into the bulkhead then slide it down into place ( about a hundred times for fit). Pencil was for marking hole for wood screw that holds the lever in place while Hysol sets. Second picture shows the setup prior to gluing - using special syringe rig.

Ailerons were much easier. I’d love to know how others have tackled this task . . . .
