   It would do me a lot of good to get this project done, so I am not   
   going to sweat this too much - in the absence of being shown the way,   
   I will likely get the single-phase 0.75kW motor, do the belts and see   
   this thing running a.s.a.p.   
   In a lifetime, sometimes it's better to get that next step done and   
   know all about what you'd do next when it comes around again.

   I built and ran a 1/2 HP electric sawmill before building the 6.5 HP gas   
   one. Bandsaws that make a wide cut have a problem not seen as much with   
   narrower cuts, the teeth need a minimum pressure to cut into the wood and it   
   adds up with length until reaching the point where the pressure to make a   
   dulling blade cut forces its center back until the front edge loses tension   
   and deflects (buckles) up or down. I tried coarser, wider, thicker blades   
   and discovered that they cracked bending around the wheels. More blade   
   tension might have helped but the blade tensioner wasn't adequate for this   
   misuse.   
      
   I didn't expect those problems and spent a lot of effort understanding and   
   adjusting for them. It's a good example of the need for debugging a small   
   (less expensive) prototype before moving to the full sized machine. The 1/2   
   HP bandsaw is back in its original upright configuration.

   get the best results from a bandsaw."   
      
   My windmill rock tumbler needed tweaking too.   
      
   Single to three phase converters were once a lively topic here.

   "Capacitors with ratings above 70 microfarad (uF) are starting capacitors.   
   Run capacitors are designed for continuous duty, and are energized the   
   entire time the motor is running."   
      
   An oscilloscope and clamp-on AC ammeter are very helpful if not essential.   
   Standard practice with high voltage is to work with only one hand. I like to   
   see the power plug lying on the bench rather than depending on a switch.   
      
   There's a crude and simple way to use a three phase motor that I decided not   
   to post. Just hinting that it exists.
