Abstract
A method and apparatus for securing a drum blank for machining includes inserting a cylindrical mandrel within a bore of a drum blank, introducing a liquid support material into a space between the outer diameter of the mandrel and the inner diameter of the drum blank, and solidifying the support material. Once the support material is solidified, the drum blank is securely held to the mandrel. Machining operations can be performed by mounting the assembly in a lathe. After machining is completed, the support material may be treated so that the mandrel can be removed from the drum blank. The mandrel may then be recycled.
