      Your Wen Lathe motor might stall due to several reasons. It could be an excessive cut, in which case you should reduce the depth of the cut. The belt might be worn, damaged, or improperly adjusted, requiring adjustment or replacement. A worn spindle bearing could also be the culprit, necessitating replacement. Lastly, the motor might be protected from overload, so try resetting the circuit.

      Excessive vibration in your Wen Lathe can stem from several causes. The workpiece might be warped, out of round, have a major flaw, or was improperly prepared for turning; correct this by planing or sawing the workpiece, or discard it and restart. Worn spindle bearings or a worn drive belt could also cause vibration, requiring replacement. Additionally, ensure the lathe is on a flat surface.

      If your tools tend to grab or dig in when using the Wen Lathe, several factors could be responsible. Ensure your tools are sharp, as dull tools are a common cause. Check the tool rest height; if it's too low, reposition it. Also, make sure the tool rest isn't too far from the workpiece and that you're using the correct tool for the operation. Finally, ensure the cam lock nut is properly tightened.
