I would never say to use gloves when operating a lathe or mill( or a number of similar machines) however when polishing a barrel against a buffing or wire wheel you will ****** the spinning barrel with your fingers/thumbs and it gets sorta hot not to mention the wire wheel occasionaly pitches wires hithernyon and that ain't no fun for bare hands. You can follow your own counsel but I,m wearing gloves,welding jacket, shop apron,safety glasses, dust mask, faceshield, ear muffs. A lathe no. no rings, no watches, short sleeves, short hair.
Also, thanks to the guy for the heads up on Chad Dixon's barrel polishing fixture. I got him bookmarked and will buy one from him. I give him your name or handle when I do. You ought to get some good will if nothing else. I don't have your name right here but I'll get it b4 I order.
