The aileron horns are cut from the same piece as the aileron yoke and rudder horn. I figured that I might as well cut them all out. Then I started making other metal parts related to the other items. The result is now the control stick assembly is completed.
Really no need to go into much detail as all these parts are pretty easy to make. One issue I had was cutting the 1″ hole in the yoke and torque tube bearings. Using a 3/4″ hole saw, a dremel and most importantly my rounded file. If this file was shaped like a rod, it would be 1″ diameter. Without that file it would have been more difficult to get a nearly perfect hole.
You can see how perfect this file fit this hole.
Here are the aileron, ruder and elevator horns.
