Duplicate the length of any AN-3 through AN-10 control rod to ± .005. (1/2 Flat) No more losing thread count or poorly measured control rods requiring aircraft re-rigging. Easy to use, satisfaction guaranteed.
Talking about present duplication methods: The tolerance on thread length to ball center is ± 1/32 so counting threads is a poor measurement, and a tape or mark on a board is not any better. Even with a caliper as big as your control rod, when you measure the old rod the setting will include the wear.* With the Control Rod Rigger well worn rod ends will center up by pushing down on the rod as the tool is adjusted. .005 is less than 1/2 flat for AN-4 and bigger. This accuracy certainly is useful when adjusting helicopter heads. My mechanic loves it and so will you.
To use this tool to adjust twisted control rods, rotate one end Counter clockwise until the control rod is flat and can fit on the tool. After replacing both rod ends, rotate the same end clockwise to the proper angle. Do not switch ends or direction when turning to the proper angle or you will have the wrong length. I recommend rotating the right hand threaded end every time for consistency. Do it the same way every time.

It is possible to clamp the unit and an extra bar to a bench, and duplicate even larger lengths than shown. The costumer can cut a 4-6" piece off their existing unit and use that piece to clamp to a bench. Labor considerations on my end make an extra 24" bar more cost effective than selling 4" bars. The 8 ft length includes truck shipping to my location and is not as cost effective as building up the length you need with 6 ft and smaller. The 8 ft. length also will have a large truck shipping cost to your location. Longer lengths would be built up using the above extra bars.
