Skywatcher focus motor
I'm trying to fit a focus motor to my Skywatcher 102 mm x 1000 mm achromat refractor, i'm following the provided instructions but I can not find any screws of any kind to remove to take off the focus knobs. Could the focus knobs be pressed on, or maybe the focuser spindle is threaded with left and right hand threads.
Would anyone here have any experience with this?
