Description
The LL-Mandrels are a precision-made concave lap used to cut and polish enhanced concave facets on a design you've
already made on a gemstone. Several companies make concave faceting equipment. The most notable is produced by Zane Hoffman,
manufacturer of the Polymetric and OMF-concave Faceting machines. http://www.polymetricinc.com/index.htm
Each set of LL-Mandrels has one each of 13, 15, 17,19 mm. diameter mandrels. Occasionally, some want to have
multiple-matched diameter mandrels. We can provide these as well. Individual LL-Mandrels may also be purchased,
priced per each. 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.
