Bushings and Pivots WS-321

Bushings and Pivots  WS-321
In this two day class we will learn to restore pivots and bearings by several different methods. The bushing machine is only one of several ways to bush a clock and is often unsuited to the task. A bushing machine also requires a skilled and knowledgeable operator achieve proper results. In addition to using the bushing machine, we will focus on alternate methods to bush a clock that achieve both greater accuracy and speed. Just as with bushings, there are several ways to restore and polish pivots. We will explore various methods and learn the difference between a properly polished pivot and one that is merely shinny. We also will learn to replace broken or severely worn pivots.

Upon completing the course the student should be able to:

  • Bush a clock using the bushing machine
  • Bush a clock using the milling machine
  • Bush a clock using custom made reamers
  • Repair worn pivots to prepare them for polishing
  • Polish pivots using burnisher
  • Polish pivots using a abrasives
  • Re-pivot an arbor with a broken pivot

The student must supply a previously cleaned clock movement which, hopefully, needs pivot and bearing repairs. An American style shelf clock movement such as a Seth Thomas #89 is preferred.
