Safety Point! Never hold any cloths, including Emery Cloths, loosely in the hand when polishing on a lathe - it can become entangled and cause severe injury. Fix emery cloths to a backing stick as shown. Alternatively clip into a sanding block or use an abrasive sponge.
Features and Application
When finishing metal by hand whilst it is held in a vice, pieces of Emery Cloth can be wrapped around a file. To get a good finish, work through grades from coarse to fine and regularly alternate the direction of the file to remove scratches by polishing across them.
