Not being able to find a focuser I wanted for my Esprit 120, that came off instantly and went on instantly I decided to make one. I did not want one that was permanently engaged with the scope. Also I refuse to spend £200+

I bought another Skywatcher electronic focuser, a piece of 3mm alloy bar and a 2.5” by 6” round bar.

I won't go into detail as I have taken photographs, what amazed me was the final luck when I attached the vacuum cleaner drive belt it fitted 100% and I had NOT measured at any stage for it to.

The knob attached to the motor has TWO grub screw holes, 3mm which is why the other holes are offset.

I am NOT an engineer as you can see but have enjoyed this. Took a day

The good thing is that the whole unit can easily be swapped over to the other side of the scopes focuser
