I'm not sure how quoting me was relevant there!
I'd really like to get a servo for that reason, but it's far too much money.

Jonathan i made a valid point of the added benefits of a servo motor namely Zero to full speed with full torque

You came back with a statement that a VFD could do that in delta mode well it can't run that way and a VFD motor combo certainly cant run as a rotary axis

So why did you quote me ?

Take a look at this video http://www.onecnc.net/videos/video_mill_turn.htm

Best not make reading mistakes like that in my exams tomorrow!

Nice video by the way...

Better get your haircut before you go then.

Re the video we can only dream.
