Fundamental Skills for Lathe and Clock Repair I

The material in this course is a basic skill set that is continued in Field Suitcase Workshop F201. This four-day basic course prepares the student for fundamental Lathe operation and clock repair skills. The student will be taught the characteristics of metals used in clocks, metal working skills, and will apply these skills to making parts and tools in class. Tool projects started in this F200 class will be completed in the follow-on F201 class and used to complete other tool projects. The course provides the student with the very important and specific options for purchasing a Lathe along with accessories needed in clock repair. There are no prerequisite requirements for this course. More specifically, the following general subjects will be covered:

  • Different metals used in clocks and their properties.
  • The skills needed to cut, shape, drill, harden, anneal and temper metals for clocks.
  • The making of some basic tools needed for the Lathe.
  • Options for buying a Lathe, spring winder, bushing tool and accessories.
