FINALLY, I got my r2e4 Bridgeport converted to single-phase.
No more of that damned RPC singing over in the corner, no.
As it turns out, the R2E4 machine is basically a single-phase machine,
anyway, except for the spindle motor (which is definitely 3-phase).
The electronics all run off two (single) phases of the incoming power,
and there are no references to the phases. All it took to get them
converted was to move a couple of leads.
To adapt the spindle, I installed a VFD and a relay isolator that would
track the F/R signals from the motor relays, and signal the VFD to
start/stop/forward/reverse.
It cost only $149 and some labor.
Now to make metal in the QUIET! G

Woohoo!
How is it working for you, is it convenient to program?
