What to do if my Wen LA3421 Lathe motor or spindle stalls and won't start?
- J
  Jonathan McclureJul 29, 2025
  If your Wen Lathe's motor or spindle stalls and won't start, there are several potential causes. It could be due to an excessive cut (reduce the depth of the cut), a worn, damaged, or improperly adjusted belt (adjust or replace the belt), worn spindle bearing (replace the bearing), or a workpiece that is too large (switch to a smaller workpiece). Additionally, check the carbon brushes for wear and replace if needed. Finally, a blown fuse could be the culprit, so replace the fuse located on the rear of the control box.

Why is my Wen LA3421 Lathe experiencing excessive vibration?
- M
  Matthew BeckerAug 12, 2025
  Excessive vibration in your Wen Lathe can stem from several issues. 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 start over. Other causes include worn spindle bearings (replace the spindle bearings), a worn drive belt (replace the drive belt), or the lathe being on an uneven surface (place the lathe on a flat surface, such as a benchtop or lathe stand).
