Rob, I don't believe the spindle is a stepper motor.

Doddy, yes, that is my ethos, otherwise it gets confusing. My other hobbies all follow that mantra.

Clive and Jazz, many thanks, I will check that out, but not right now, because the wife and I are off to the pub for food, it's Christmas eve so the next couple of days will be solid with visits and visiting.

So while I'm on the subject. I wish you all a good Christmas and hope you have a merry ol time.
