Pictures would be great. What sort of bearing is your main gear wheel sitting in?
Hi Phil,

My azimuth bearing is fixed and it is the worm that travels, attached to the aluminium rocker you see in the photo. A piece of 10 millimetre tubing is in the centre and acts as a pivot. The power cable is fed through this tube. A lovejoy coupling connects the allthread worm to the stepper motor.
