I bought one of these lathes several months ago and had to make the same decision. I went with a new single phase 1 hp. replacement for the old 3 phase motor. I hated to spend the money but now that it is up and running I am glad I went this way. By converting the 1 hp. 3 phase motor to single phase you will loose 1/3 of the rated power of your motor. That would make your old moter a 2/3 hp. After turning a burl bowl about 7” in dia. I just dont think a 2/3 hp motor would have enough power. The replacement moter has to fit iinside the headstock housing (at least on the earlier models) so I had to get a moter with a clamp on base. This allowes you to turn the starting capaciter down and lets the moter fit into the cavity. I also was able to use the built in on-off swich for my new single phase moter. Hope this helps.
