Steve well done. I've been doing some more play with the remnants of by car jack thread. I used the mill to cut the slots in the hob this time, much nicer result. I've made a small gear (65 teeth I think) to drive a cheapo EQ3 lookalike which I want to put a camera on.
I picked up a gearhead motor with a nominal output of 6.7RPM at 12V which is by my calculations very close to the combo I'll need to drive the RA axis of the mount (it already has a worm gear drive which seems to be need six turns of the worm per hour).
I've also just recieved four faster gearhead motors from the US which I want to experiment with to see how much range I can get with PWM speed control.
Unfortunately my normal laptop is dead at the moment so I don't have access to software to shrink photo's etc.
Bob
