      Lightning Lap Concave Faceting Mandrels

      The LL-Mandrels precision-made concave laps are used to cut and polish enhanced concave facets on a design you've already cut on a gemstone. Several companies make concave faceting equipment. The two most notable are Polymetric and OMF-concave Faceting machines https://www.polymetricinc.com/products.htm, and Ultra Tec Fantasy Machines found at https://www.ultratec-facet.com/

      The advantage of the LL-Mandrel is in the ability to have just one lap to do all your work, just by cleaning and changing the polishing medium. Your angle-integrity is preserved, as there are no lap changes. Lightning Lap Natural Mandrels can be used with 1200 or finer grit diamond bort, spray or paste. You can also use waxes with oils, water or any kind of oxide polish.

      You can clean with alcohol or soap & water, then apply the next polish. However, most users dedicate 1 lap to 1 polish for fast polish changes; and to reduce polishing medium expenses.

      The Lightning Lap Mandrels are harder than cast iron and hold your polishing medium on the surface. They are very durable and should last for many years of service.

      The mandrels can be purchased separately or in sets of 4 or 6. Each #1 set of LL-Mandrels (one each of 13 mm, 15 mm, 17 mm and 19 mm diameter mandrels).  #2 set of Natural LL-Mandrels has one each of 9 mm, 11 mm, 13 mm, 15 mm, 17 mm and 19 mm diameter mandrels.

      Occasionally, some want to have multiple-matched diameter mandrels. We can provide these as well. Just contact us.
