I am looking for a South Bend 13" lathe and am currently trying to do my research to figure the good, the bad and the ugly about what's out there. One had the three phase motor changed out to single phase. It's listed as a 1 HP motor. That's when i realized I didn't know what size motor was standard or recommended for a 13" lathe. What's the answer? Side note I already have a rotary phase converter good to up to 3 hp so that isn't an issue.
