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.
