I originally designed this to add a 28BYJ to motorise my hadley but it didnt really give enough torque. I decided to upload it anyway as it stiffens the two legs a bit (I made my mount out of wooden dowels; not a brilliant choice!).
If you want the files for the pulley system I modified https://www.printables.com/model/377199-motorised-mount-for-hadley-telescope so I didnt have to reprint my bearings. It probably would have worked if i used an actual bearing for the azimuth instead of the plastic ones.
The author marked this model as their own original creation.
