The Hi-Tech Diamond All-U-Need lap machine is the most portable and affordable way to get started with your lapidary workshop, filling the role of both a cabochon maker and a flat lap. Grind flats, re-work crystals, make free-form cabs, or shape and polish glass pieces all from the same machine! Specifications The machine is manufactured for use with 6" or 8" disc and pad diameters with a 1/2" arbor and powered by a 1/4 hp, heavy-duty, ball bearing, DC motor. It can complete tasks as a cabochon maker and a flat lap. This motor is variable speed so you can work at whatever pace you desire, delivering speeds from 800 rpm to 3,400 rpm. This portable machine can be used anywhere. Whether you're at home, in the shop or on the road, this quiet machine won't disturb others around you. It's lightweight, rustproof and impact-resistant, making it even easier to travel with. The coolant reservoir, which holds about a pint of water, prevents heat buildup while you work and removes dust particles so you don't inhale any harsh chemicals. That pint of water will give you two to three straight hours of work without refilling. The black splash guard keeps water off you so you don't get soaked while you work. Cleanup is as simple as it gets: Just remove the black spray shield, rinse with clean water and you're ready to work again. SELECTION & COMPATIBILITY The Rock/Mineral version is best to smooth and polish rocks and minerals to make free-form shapes and cabochons for necklaces, earrings, rings and other jewelry pieces, creating flats for larger pieces or on the backs of cabochons, and polishing a large variety of natural and synthetic gem material, enamels and metals. Glass/Crystal version is geared toward cold glass workers and glass fusers to grind, shape and polish glass and crystals to make free-form shapes and cabochons for necklaces, earrings, rings and other jewelry pieces, creating polished windows in glass marbles or beads.
