      I agree, although I would equally strongly suggest that you avoid a
      static phase converter and go straight to either a rotary phase
      converter or an electronic VFD.







      maybe cheapest & simplest solution is a 3ph motor of at least 2x the
      current mtr HP......used as an idler , it will run on 240 ( 2 lines of 120 ) once
      it is started & will generate enuf juice for full HP operation of the lathe
      mtr.w/ out additional capacitor balancing ...u can start it running ( since
      3 phase has no start windings ) by a rope on a pulley , a single phase pony
      mtr belted to it , or a start cap of abt 80 MFD /HP & a momentary switch ,
      which u release almost immediately as it gets up to full frunning speed
      ,usually a second or less.......u shud be able to scrounge a 3 hp mtr for $10-
      30....., mayne even given one w/ a buggered shaft since u will not be using the
      shaft to drive anything .......been running i HP , 5 hp & 71/2 HP shapers,& a
      3 HP chop saw from a 10 HP idler for a few years now..( of course one at a
      time)................if u go this way , i can help talk u thru wiring it up &
      safety issues.........
      best wishes
