Bushings and Pivots WS-321

Bushings and Pivots WS-321
In this course 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. 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.

Please contact the instructor, Al Dodson with any questions at adodson@nawcc.org . All necessary tools are provided.
