I have been having problems with my 1642 for the past 3 years. I have replaced all the bearing, spindle shaft and it still wont turn true. I have contacted the manufacturer and have gotten a run around every time I have called. When you are turning large bowls the 1-1/2 hp motor just cant handle it. If you are true craftmen and are doing accurate detail work I wouldn't sugesst buying the 1642. If you want quality customer service, do not buy the Jet 1642.
