Begin by carefully cutting a very shallow silt in the fin trailing edge at the hinge location. This first cut is to establish your cut in the right place, so concentrate on staying on the centerline and don't cut too deep! Make three or four more cuts in the same line,...

    Glue the stab to the stab saddle by applying thin CA generously along both sides of the fuse. Also apply thin CA in the fin notch and at the front and back of the stab to insure that the glue fully penetrates into the joint. Finally, add a small fillet of thick CA along both sides of the fuse/ stab joint to fill any gaps.
