Tutorials and Learning

Class notes: The notes used for the Sherline Lathe Intro class are available on the committee drive:


Video tutorials: An excellent set of Sherline-specific lathe tutorials from MiniMachining
Lathe tooling: The learning center at The Little Machine Shop has good descriptions of all of the various types of lathe workholding and tooling and what they are used for. While it is intended as a cross-reference to the products they sell, it also explains what these things are used for.
