Reversing could get interesting. That can put a lot of stress on a

reverse instead of the lathe, a situation that could really make your

You could get around this simply by pausing with the switch in the off
position until the spindle stops, then applying the power in reverse, right?

Thus eliminating the "reverse it quite quickly" which was
promised about four articles back-thread. :-)

If you want to do this, you want a hefty rotary phase converter.
I don't think that a "static" phase converter as made by "Phase-O-Matic"
could handle a two-speed three-phase motor very well. It will start
well on one or the other speed, but not both.
