I'll be picking up my Bridgeport 2 HP 2J in a couple of weeks, so
it's time to start working on a rotary phase converter.

Others have given you good advice on rotary phase converters, but I'll
give you my take. Having run Bridgeports on rotary converters, static
converters and VFDs, a rotary would be my last choice. A VFD is much
more convenient, even with a 2J variable speed head, and a static
converter is more than adequate. RCM dogma says that you can't plug
reverse a BP with a static converter, but I did it for many years, as
does a friend of mine with 3 mills in a commercial shop.


Of everything, VFDs are the best option for a Bridgeport. Despite
having a phase converter, I run mine on a VFD and could not be any
happier.
