Does anyone know how to hook up a shaper attachment for a Bridgeport? I have an older E series,that had the wires cut inside the disconnect box. There are only 3 wires, a green, white and black. Does this mean that the Shaper motor is 220 but only single phase? I'm used to seeing a red, white, black and ground. I tried hooking it up as a 110 Volt unit but it only buzzes.
Thanks
