3M Adalox paper-backed aluminum oxide sanding discs are used routinely by a majority of bench jewelers. In addition to using them for sanding, Jeffrey Mathews, CMBJ, of Jeffrey Mathews Designs, Dallas, uses them as a polishing device to reach narrow, hard-to-get areas of his fabricated pieces. Here’s how you can perform his trick:
- Reverse a standard sanding disc on its mounting mandrel.
- Apply pressure evenly with another coarse sanding disc to the backside of a standard sanding disc while it’s mounted and spinning.
- Apply polishing compound. (Step #2 has roughed up the paper surface, allowing it to hold a charge of polishing compound.)
- Finish it-the backside is now ready for pre-finishing and finishing of hard-to-reach areas on an article of jewelry.
3M brass-center snap-on sanding disc products are available through most bench tool and equipment suppliers.
Benefits for the Working Bench Jeweler
- Makes a nearly impossible task possible. It allows polishing access to extremely hard-to-reach areas.
- Allows you to offer a cost savings to your customer: The technique retains high quality and saves significant polishing time, yet the charges for the service remain the same.
- Continuing education. This technique will be helpful to anyone taking the practical bench tests of the JA Bench Jeweler Certification program.
