    I read that in choosing a VFD over a different type of phase converter there is a reduction in motor RPM in one of the choices. Is this correct?

    EDIT: From my reading it looks like it's a reduced torque (not RPM) that can be encountered at lower RPM's but only on certain VFD's Is that right?

    Thoughts: I want to keep all the stock controls and switching and a good VFD looks great at first glance, unless I am missing some important details. Am I?

    In fact you can overdrive your motor with a VFD. By adjustin the carrier frequency either speeds up or slows down your motor.
    You will also find that the VFD option will be the most cost effecient. It also gives you many options compared to a static phase converter or rotary phase converter. It will give you the options to jog your spindle, spindle braking, adjustable speed control which is very nice, you can also wire up a safety stop button incase of an emergency.
    The VFD's are also relitevly easy to wire up. img_3422.jpg

    I got my inspiration from a member on this fourm by the name Thomas Utley.
    Here is a youtube of his control,

    I have some info and questions going in the VFD forum so maybe some updated pics are in order while I figure that out?

    Found some original scrape marks under the headstock!

    Really nice work there!

    This is about as far as I wanted to go cleaning up the headstock. It's pretty awkward to work with but I am ok with it.

    Some tedious and delicate work to get the paint off of these!

    Hey Kevin,

    Your lathe is coming along nicely....

    Would you mind measuring the shaft on your taper attachment, that holds the bed clamp for me? Just the diameter and exposed length of the rod.

    Thanks...

    Do you mean this?

    I never got the shaft removed so IDK how long it is in it's stock form.

    Darn pictures flipped too sorry! It's 5.75 from main assy to the outrigger clamp body and 8.65 to EOP

    Got the diameter! Just under 7/8's ???

    The clamp body is a slip fit BTW, at least on mine.
