Magnetic Polisher Machine

A magnetic polisher speeds up the polishing process considerably. However, there are still a number of steps required to polish a piece and to maintain the machine.. These instructions are geared toward the smaller sized machine. For the larger machines, more items can be polished using less time. 1 First, use a fine jeweler’s file to remove scratches, excess solder, and other blemishes from the metal. Try to remove as many blemishes as possible with the file. This is especially important because the machine is not designed to remove scratches. 2 Make sure pieces are clean. For example, cast pieces should be free of all investment. (Ammonia and an old, soft tooth brush work well for cleaning investment off charms.)
