I am a jewelry designer and metalsmith by trade and have been doing engraving for a couple years. I really enjoy engraving but I make jewelry from carving wax's to the stone setting, so I don't have as much time as I would like to focus on engraving. Then I only get to do it when it is called for in a design. I typically only engrave Platinum,Gold, or Palladium, so when I do there is burs along the side of my engraved line. When I get rid of them by a hard felt wheel I lose some of the detailing. How do I get rid of the burring or what do I need to do different to not have these burs? I am hoping to take Sam's class this August at GRS if the boss will send me. Thanks for the help!
