6. The control horns will need to be trimmed as shown. Use a dremel tool with a sanding drum
attachment. Do this work in a well-ventilated area and use eye protection!
7. Apply 30-minute epoxy liberally to the bottom of the horn and to the wood of the control surface.
Install the horn. Wipe up excess epoxy with a paper towel and alcohol. Temporarily install a 3mm bolt
through the bolt holes to ensure proper alignment of the two horn halves. Allow the epoxy to cure.
