I have got the motor on and running. Yep it works...phew. Had my fingers crossed so Im happy so far. Seems to be at sidereal rate as far as I can tell on the bench. Slip clutch works too...really well. I need to find somewhere to put the wires and connector block and a panel mounted 6 pin female plug too, rather than the plug it has now.

Altitude adjustment is via the bolts holding the discs on the front of the mount, so friction only. Its a tight fit as is but to be safe I'll add a threaded rod that will go under the inner part (the bit with the pillow blocks on it) and should then hold the lot secure and do double duty as a fine Alt adjustment.

A couple mote photos.
1. My ugly..for now...motor mount.
2. The worm from the back. The worm block is screwed to a 6mm plate that is has a small amount of adjustment to get the worm to sit as close as I can get, to perfection.

Edit: The second photo makes the worm block look askew...its a camera angle thing it is square on.
