Ball turning tool

On the Internet there are many articles on devices for ball turning. However, there are few devices that allow you to make balls with an exact diameter. Most designs (horizontal) are also designed to a specific lathe type and are not useable on different lathes. For this reason I have developed my own design that can be used universally on any lathe type and can make perfect balls with an exact diameter.
