I've had my lathe for several years and have been running it on 110v since I got it. As I'm not electrically inclined I asked a neighbor to help me wire my lathe for 220v operation. The wiring went without a hitch except that it had more power running on 110v than it does on 220v. With a shaft in the chuck and the lathe running about 300 rpm I can grip the shaft and slow down the rpm considerably. Obviously this lack of power also shows up when turning. My neighbor swears up and down it's wired for 220v. I've attached the wiring diagrams for the main control box and for the motor terminal box. The picture is the low/high (110/220) voltage wiring diagram on the inside of the motor terminal box cover. I could start probing around with my multimeter but I thought I would consult the resident electrical gurus before making matters worse. Thanks in advance for your help. Tom S.
