mount can be adjusted by loosening the positioning bolt (Fig 12), moving the tool rest to the desired
height, angle and/or distance from the wheel, and then retightening the positioning bolt. The tool rest
can also be completely removed (Fig 13) from the GP-8 Super Cabmaker base if the operator so de-
sires.

Rough shaping of the gemstone material should be performed first with the 80-grit wheel with maxi-
mum water flow from the hood mounted water control valve. It is recommended that you only pump
clean water to the GP-8 Super Cabmaker water system and never recycle your drain water back to
your grinding wheels or expandable drum.
Due to the steel alloy core construction and brazed nickel diamond bounding of both wheels, a “ring-
ing" noise will be heard during grinding and sanding. This is normal and should be of no concern.
Should coolant/flushing water flow be interrupted while grinding with the brazed diamond wheels, the
diamond may “glaze over" or dull the diamond bond. The diamond bond can be “dressed open" or
sharpened periodically by taking the green carbide stick and lightly touching it to the diamond grinding
face of the wheel while rotating (Fig 14). Only apply a slight pressure - for no more than 2 to 3 seconds
- with full flow of cooling water when “dressing open" the wheels. Do not over-sharpen as the wheel life
will be shortened. Never use the brazed diamond wheels dry under any circumstances.
Always ensure there is a clear, constant drip of water flowing off the rotating wheels into the reservoir
tank. Also, don’t over force the gemstone material into the diamond wheel surface while grinding. Al-
low the diamond bond on the wheel to work smoothly with a constant and steady application of hand
pressure. Rotate your gemstone frequently while grinding to uniformly remove material, nicks and flat
spots while rounding and contouring.
Remember, satisfactory results are dependent on the user's skill and experience, as well as the gem-
stone and equipment being used.
