This two week course covers some of the most common repairs encountered by the clockmaker; damaged wheels, worn pinions, broken ratchets and many others. We will begin to acquire the knowledge and skills needed to accomplish these repairs. We will accomplish these tasks using both traditional hand techniques and using the Sherline machines to aid in these repairs. There are a wide variety of tasks but all are accomplished with the tools we have already used; saws, files, drills, the lathe and milling machine. In addition, we will work extensively with mainsprings and mainspring barrels. restore pivots and bearings by several different methods. We will also continue to fabricate some of the tools we will use in making repairs. There is much to accomplish so this will be a very hands on class.
