Another way to motorise the 10:1 using the accufocus is to mount the accufocus away from the focuser somehow and run a belt between the focusing knob and the output shaft of the accufocus.
I have an Accufocus attached to my JMI NGF-DX3 which is a crayford, I had to make up a little sleve to make it fit though. The Accufocus' flexable shaft will fit directly onto any focuser shaft that is 8mm in Diameter, might be worth checking that out first.
I have found although the Accufocus is a brilliant and fairly inexpensive way to get pretty good motorisation, I wish it were a little slower on the slow setting. Just my personal preference.
