Tips for speedy and safe clean up of the inside surface of soldered or cast band rings

For about seven weeks every summer at camp, I help my teen stu-dents fabricate hundreds of rings. Along the way, I’ve collected a bunch of ring-making tricks and tips, and here are two favorites for speedily and safely cleaning up the inside surface of a simple, average soldered or lost-wax cast band ring.
1. The first safe and easy tip for cleanup on the inside edge of a thick band involves a deburring tool, which is a simple and inexpensive hand tool normally used by plumbers and other tradespersons to remove burrs produced by sawing PVC pipe. The tool’s rotatable blade creates a clean bevel on the sharp sawn edge of a tube, ring band, or bangle bracelet in just a few seconds and eliminates the need to file. Because I work with teens, my safety recommendation to prevent blade slippage is to hold the tool vertically and stationary and then to slowly and carefully rotate the jewelry object around the blade’s cutting edge instead of rotating the blade within the jewelry object.
2. A little curl of silver swarf immediately indicates you have the blade at the correct angle to quickly produce a clean bevel on the edge. There won’t be any need to file if you deburr slowly and carefully on both sides of the band.
3. My second tip for inside ring finishing is to make a scrap leather holding device for sanding and polishing a newly beveled ring band. Cut about a 1-inch by 8-inch strip of chamois or leather scrap.
4. Test the leather strip by encircling whatever it is you want to hold to ensure there is plenty of extra space around the object and enough leather to hold it firmly, too.
5. To use the strip, fold it in half lengthwise with the rough side of the leather facing out.
6. Encircle the ring band with the folded strip of leather.
7. Grasp firmly against the band so the ring is securely held within the strip.
8. Abrade away. The beauty of this method is portability, a firm grip, no hot metal to hold or lose hold of, clean hands (when it comes to buffing with compound), and no specialty tool to purchase.
