Spherical Turning on a Manual Lathe

The video tutorial explains how to machine a ball handle using a manual lathe. It covers the need for custom-sized spanners, the process of adding an axis to the lathe, and the geometrical features of a ball handle. An alternative method for ball turning is also discussed, along with the final steps of machining and threading the handles.

What are the three main geometrical features of a ball handle?

Describe the process of forming the smaller sphere in the ball handle.

What is the purpose of using a marker pen on the smaller ball?

Explain the alternative approach to machining a ball handle mentioned in the text.

How is the thread tapped into the ball handle to ensure it is perpendicular to the flat?
