Making an Aluminum Disk with Kathy Spriggs
This video demonstrates how to make a disk from a non-circular plate. A 1” aluminum plate is first scribed using a compass, and center-marked with a punch. The plate is then rough cut using a horizontal band saw, and center drilled using a vertical drill press. An aluminum log/billet is then decked on a lathe and used to pinch the aluminum plate against a live center mounted in the tailstock of the lathe. The end result is a 9” diameter disk, 1” thick.
