Mounting Grayhill Encoders On Rookie Transmissions

[Peyton Yeung]

The kit transmission last year was a toughbox mini. The CIMple box was last in the kit in 2012.

On our custom WCD for this offseason, Grayhills 63Rs were were loosely pressed into the inside ends of the rear axles and the encoder housing was secured (so it won't spin with the axle) by zip tying the signal wires to the frame (method found here on Chief Delphi).

I admit I am not familiar with the KOP drive train, but it might be easier to figure out how to mount them on the outer live axles instead of to the transmission? For the method I described above all you really need is a 1/4" hole at the center of one of the other live axles.

The only live axles are the center wheel/gearbox output. The outer wheels are on dead axles.

My mistake. I just meant the outer axles.

If all you need is a 1/4" hole to mount the encoder, you can attach a 1/4" shaft coupler to the encoder stub at the back end of the main output shaft. We've done this in the past with a potentiometer when we were making a TB-mini into a super-sized servo to steer our t-shirt cannon.

The 2013 KOP gearbox was a flat-plate Toughbox mini. CIMple boxes were last issued as part of the KOP drivetrain in 2012.
