Finishing Tools
Finishing tools include files, "emery sticks" made of wet and dry paper affixed to ruler-length wood, flexible shaft tools, buffing machines, steel burnishers, and polishing threads.Filing
Filing removes rough edges and creates a smooth finish. Depending upon the application and the intended result, a jeweler may use a flat file, a round file, a triangular file, or a square file.Sanding
Sanding is one of the most important processes in finishing, and is done to remove filing marks. To begin the sanding process, begin with coarse 220-, 320-, and 400-grit emery paper. Once the filing marks are completely removed, finer sandpaper in grits of 600-, 800-, or 1,000-grit paper will remove the marks left by the coarser sandpaper. When the sanding process is done, you're ready to polish.
Polishing
Polishing is done using a flexible shaft tool outfitted with muslin or felt wheels. Different types of abrasive types of compounds are used to result in different finishes.Steel burnishers are used to give a mirror-like shine to finished edges, while thin polishing threads can be used to polish and refine the inside of small holes.
A buffing machine can also be used to polish jewelry. When using a buffing machine, always be sure to wear the proper safety equipment, and stay safe by educating yourself on how to use the buffer.
