Includes Stainless Steel Tray, Cast Body, Baseboard, and Motor.

This unit is set with one 8x2" inch diamond wheel and one 8x3" inch expandable drum. 

Multiple wheel configurations are avalible! 

Please call us if you wish to change the wheel grits, we can customise any wheel configuration tailored to your needs. 

The body of the machine is a heavy walled, durable aluminium casting. It has wide cast aluminium guards eliminating rust and sheet metal vibrations. The latest upgrade made on the GMP models is the new hoods. The hoods now attach to the body with a more robust connection. The lengh and diameter has also been increased to accomodate the comfortable spacing of six wheels.

Water fittings are supplied, with independant tap control to each wheel, where the water is spread across the face of the wheels and then minimized by means of a rubber flap. The machine is mounted in a heavy duty, large capacity, stainless steel tray.

A 1/3hp motor is supplied and combined with a Three Speed Pulley Set runnings at speeds; (850, 1420 and 1988 rpm) to suit a range of uses. 

We recommend that polishing be done separately, see: (GEMMASTA GSP8 Polishing unit)

Gemmasta was originally designed and built by Roy Gaerth in Adelaide in 1972, these heavy duty lapidary grinders have long been the machine of choice for many people in the Australian Opal Industry, and in Gem and Lapidary Clubs right around Australia. Roy eventually sold the manufacturing rights to Gemmasta Lapidary Equipment in Flinders Park, South Australia and it was later aquired by Shell-Lap in Adelaide. In 2018 Shell-Lap closed when the owner retired and the manufacturing moved to Ballina in NSW.

Since then the machine has undergone several design improvements to make it even better than the original.

The Gemmasta GMP's now comes with a full stainless steel tray that replaces the plastic moulded tray that was previously supplied with this model. The bearings have been replaced with fully sealed units.

The 3/4 Inch shaft has been updated to a full 1 inch stainess steel shaft. This provides additional rigidity and greater support, particularly those users that want to run heavy sintered grinding wheels.

The 1 inch shaft also means that lapidary wheels used on this machine do not reqire bushing and are less prone to vibration.

 This is a machine that is built to last, made of solid cast aluminium components with a lifetime warranty against manufacturing faults.
