I traded for a Gold Screw panning machine. The second day I went to use it the pulley came off the motor. After looking at it, it looks as though someone did some work on it that was sub standard. Basically I think I need a motor because I cannot get the pulley to re-mount. Is there anyone out there that can help? I tried contacting Gold Screw direct, but they have not gotten back with me. I traded for this machine because I don't have the money to buy brand new. I live in AZ. My name is Pat 623-826-7629
