Why is my Holzstar DB 305 VARIO vibrating excessively?
- A
  Angela CollierAug 13, 2025
  Excessive vibrations in your Holzstar Lathe can occur for several reasons. The workpiece might be warped, out of round, have large weak points/cracks, or hasn't been prepared properly; in this case, plane and cut the workpiece in preparation for turning. Other causes include worn spindle bearings (have the spindle bearings replaced), a worn belt (replace the belt), a loose motor mount (tighten the screws and handle), or the lathe being positioned on an uneven surface (place the lathe on a level surface and align).

  A rough surface on your Holzstar Lathe workpiece can be due to a blunt turning tool. Resharpen the turning tool. It could also be that the turning tool bounces. To resolve this, hold the turning tool with less overhang.
