James,
The only vise to use if you have any choice is a Kurt. Everything
else I have seen or used will move the work when you clamp.
If you get a Bridgeport or similar 3 phase machine, the easiest
way to convert single pahse to 3 phase is a variable frequency drive
(VFD, inverter for those ebay searches). They all output 3 phase, just
make sure to get a 220-240 volt unit. They will all take a sigle phase
input even if they don't admit to it. If they have no single phase
rating just oversize it by about 50% - if you need 2 hp buy at least a
3hp. Make sure you can get documentation for whatever you buy so you
know how to wire it and set the limits for speed, accel, decel, & remote
variable speed.
VFDs work far better than the cheap 3 phase converters which really
need an idler motor to smooth them out. If you have the time and spare
parts you can make a converter with some capacitors and a 3 phase motor
but it is big, noisy, and needs to be tuned to the load. There are many
plans floating around the net for these.
