This is a video of using a home made ball turning tool on a lathe. The basic design of this tool is provided on Steve Bedair's excellent website. This video shows how the turning tool cuts a sphere into the end of a shaft. It can be used to make ball ends for handles and other decorative items. This particular project will result in a part that will be used as a GPS mount in an airplane. This part is turned out of 1" aluminum stock. One end was turned down to 7/16" with 14 TPI threads cut on the lathe. The ball end was turned down to .975 for a length of .978. The ball turner itself was made using a Grizzly G4003 12 x 36 lathe, and a Grizzly G0484 mill. This part in the video is also being turned on the Grizzly 4003.
