Mounting Grayhill Encoders On Rookie Transmissions

Anyone tried adapting a standard 63R Grayhill encoder to it ? Hard, easy ? Is there enough room between the cims ?

Our rookie team wants to use Grayhills if possible. Unfortunately we don't own the transmission.

Thanks

Dave, don't quote me on this, because I haven't looked at the kit gearboxes in a while... but:

The AndyMark gearboxes that support the US Digital encoder right in between 2 CIMs don't have enough space to place a Grayhill in the same spot.

We've worked around this problem in the past. It's not ideal, but it actually works well - scroll down to the 4th picture:

Note that there is a wood dowel inside the surgical tubing to prevent it from collapsing and twisting. There is nothing holding our custom plastic mount in place other than the tension from the surgical tubing, and the curved sides that match the profile of the CIMs. You can take the encoder off by just pulling straight back, and stretching the tubing.

Thanks everyone for the input
Shawn, exactly what I was afraid of
