Brian: I did a metal spinning demonstration for my "Processes of Industry" course in College.
(4) importent things are: 1) Select an aluminum that does not work harden or plan on anealing the in process work many times or it will spring back and in the end work harden and crack. 2) Wood mandrels should be a good hard wood that will not separate along the grain structure. 3) Wood lathe should have a head-stock bearing that can take a substantial lateral load. 4) Spinning tool might need to be 24" long or so of hickory or the same material as a base ball bat Don -------------------------------------------------------------------------------- ----- Original Message ----- From: "Brian Kraut" <[email protected]> To: "KRnet" <[email protected]> Sent: Thursday, February 22, 2007 8:34 PM Subject: RE: KR> Spinner bulkheads >I have always wanted to try metal spinning on my lathe, but have not had a > chance.
