The metal lathe is a precision machine for shaping metal. With it you can make replacement parts that are not available, new parts for a machine (think miniature steam engine) or tools for making other things.

In this class you will learn to center drill a piece of metal, make the end flat and make it a precise diameter, +/- 0,004". You will also learn to make internal and external threads with a tap & die. We will discuss the various cutting bits and when to use each. Most importantly, we’ll cover how to avoid hurting yourself or others while operating the machine.

Min age: 15 years old - adult

Your metal lathe instructor, William (Bill) Crispell, retired from a 35 year career in Industrial Automation. In the early days he designed and fabricated the control cabinets, occasionally making use of the metal lathe. On retiring he purchased a 1953 South Bend Heavy 10 lathe renewing his interest in manual machining. Restoring his lathe was the first project. His equipment list has expanded to include welders and a milling machine. He tuned and modified Decatur Makers’ Grizzly G4000 to offer this class.
