Measures approx 7-1/2" x 5" x 4" with a plethora of moving parts: optical head that pivots up and down; focal knob calibrated from 0 to -90 and +10 to + 80; horizontal and vertical adjustments with a locking lever; and a 1-5/8" dia ball with a 1/2" hole in the bottom for a mount.

Budding lapidarians will lap up this rock polishing kit which is so complete it even contains some rocks.

In addition to the tumbler, the kit includes an assortment of jewelry findings, a #300 4-Step Grit Pack and a detailed manual giving you easy to follow instructions.

As a hobby, our Uncle George for many years collected and polished a wide variety of rocks which he found interesting and made beautiful in and of themselves. The #300 4-Step Grit Pack is available separately, for when your grit has run low, and includes 4oz. coarse, 4oz fine, 2oz. prepolish and 2oz polish grits, and we also have spare retaining rings available for the barrel.
