I have found a site where someone uses a Robofocuser motor and used different size pulley gears to improve the focusing.

Currently, I'm building a 12.5inch f/4 and will try it with a Keller focal reducer so get it near f/2.8. I had used this focal reducer on an AstroTeck 8inch f/4 and it worked well. At present it is the focuser that is holding me up. I ordered and paid for a FT3515 in Mid January and Wayne tells me that my order is in the "pipe line" and I have to wait my turn.

That mount will be fantastic for this setup. Tell me more about these scopes you're building. What flat field lens will you use and what will control the scope's coma? Are these astrographs or Newtonians?
