Jerry,

I'll concede that point, for a sherline or other small type machine,
steppers
are fine, but this guy is converting a Bridgeport size machine. I have never
used a Xylotex drive, and I hear good things about it on the list, but if I
was doing a bridgeport sized machine, I think the 35V limit will be too low
to achieve reasonable rapids.
