Does anyone know of any mini high-speed spindle plans that are available? I would like to use one that can fit within the spindle of a Sieg X2 and use an outboard drive motor. Other than that I'm pretty much limited to getting rid of my X2 and getting a Sherline or Taig. My mini-mill has the no. 3 Morse taper. I intend to limit my machining to plastics and aluminum with bits with a .125" shank size up to .25". I would prefer that the spindle be able to accept either DA or ER8 collets.
