    Pics will definitely be posted, once it's home and cleaned up! Only problem may be getting far enough back to get all of it in the frame...

    Alistair, I know what you mean about VFDs and unusual lathes - my Holbrook has a 3-speed motor, 415v only, and I've had to do a lot of electrickery to power it from a (hacked) VFD, it has worked so far though...

    The Mill has 3 motors (spindle, feeds/rapids, suds pump) so a VFD conversion could get even more complicated than the Holbrook, which has 2 VFDs in it... And a scary electrics cabinet, not least the open 3-speed switch with 700V in fingers' reach - I really must put a cover over it!

    I've been plumbing the depths of t'internet looking for phase convertor plans, found an interesting arrangement that uses a dual-voltage motor to generate 415 from 240 single phase, LOTS of contactors in it though! http://www.mig-welding.co.uk/forum/t...5/#post-350783 is the post with the diagram, if it works it would mean no need to change contactor coils, overload relays etc. - after the Holbrook something *simple* would be nice!
