It sounds as if your last operation is causing the problem. If you tumble the S.S. rods, are you using either S.S. or porcelain media? Another problem maybe the liquid compound used in the tumbling operation. Check the chemical to make sure it has good lubricity and is recommended for burnishing.

Sorry! Finishing.com is temporarily Read-Only.
Ted Mooney is retiring but I have several offers to take it over.
We're working hard to make sure we find it the best new home.
