 Introduction to Machine Tools and Materials

In this course we will explore the materials used in clocks and methods used to manipulate these materials. We will also work with these materials to construct several tools used in clock repair. Measurement is basic to any kind of precision work and we will study and use the micrometer and caliper to make measurements to aid in our work. We will work extensively with the Sherline lathe and milling machine. These machines are moderately priced and ideally suited to the clock repair shop. They also greatly reduce the time and hand skills required to accomplish many common repairs. This course is the basic building block on which all of our repair skills are built. There is much to cover in a short time and continued practice outside the classroom is essential to becoming a proficient repair person.

Upon completing the course the student should be able to:

·         Read and use, both English and metric calipers and micrometers

·         Convert from one system of measurement to the other

·         Identify common metals used in clockmaking and understand the differences 

          between some of the  various alloys of these metals

·         Harden and temper tool steel

·         Make several useful, small tools used by the clockmaker

·         Properly use saws, files and other basic tools

·         Safely use a torch

·         Use soft solder to achieve a reliable, unobtrusive joint

·         Use the Sherline lathe and turn to dimension

·         Use the Sherline milling machine for various milling operations


Prerequisites – WS-109 Introduction to Clocks, or consent of the instructor.
