GP-6 CABMAKER SAFETY SILICA DUST WARNING Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis.
GP-6 CABMAKER SAFETY ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times! In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
GP-6 CABMAKER SAFETY ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS To avoid the possibility of the appliance plug or receptacle getting wet, position the tool to one side of a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip loop," shown in illustration below, should be arranged by the user to properly position the power cord relative to the power source.

GP-6 CABMAKER SETUP CONTENTS In the shipping crate, you will find one Barranca Diamond GP-6 Cabmaker mounted to a 3/4" plywood or plastic baseboard, one package of six rubber feet and mounting screws, one Ground Fault Circuit Interrupter (GFCI) and one 1" x 1" x 6" sharpening stick.
GP-6 CABMAKER OPERATION AND ADJUSTMENT PRE-START Your unit is assembled at the factory such that the Belt tension between the GP-6 Cabmaker and the electric motor is set to the required tension. Finger tip pressure on the belt (halfway between the motor and drive shaft pulleys) should show approximately 1/2" of belt deflection (Fig 1).
GP-6 CABMAKER OPERATION AND ADJUSTMENT START-UP Place the GP-6 Cabmaker on a strong flat table or bench. A power test can now be conducted to make sure the motor is operating and all moving wheels and blades are correctly aligned and secured to the main shaft. Plug the enclosed Ground Fault Circuit Interrupter (GFCI) into a 110 to 120 volt 60 Hz minimum 15 amp circuit wall outlet (Fig 5). If needed, plug an extension cord into the GFCI.
GP-6 CABMAKER OPERATION AND ADJUSTMENT PUMP SET-UP A submersible electric water pump is used to supply water to the polishing wheels as coolant and lubricant. The pump has a flow control adjustment on one side and should be adjusted for maximum water intake (Fig 10). It is recommended that a 5 gallon bucket be used as a water reservoir into which the submersible pump should be placed. The level of the reservoir water should be monitored so that water the pump always remains fully submerged.
GP-6 CABMAKER OPERATION AND ADJUSTMENT PUMP SET-UP (continued) Keep the water hose away from the electric motor and belt guard to prevent damage from moving parts and electric shock hazard. The pump should always be used with clear, clean water so as to avoid grit/abrasive material, mud or rock fragments from scratching the gemstones during polishing or clogging the pump valves. For optimal water flow, adjust both the pump and the brass intake valve to their fully open positions.
GP-6 CABMAKER OPERATION AND ADJUSTMENT DIAMOND WHEELS The Diamond GP-6 Cabmaker comes equipped with two 6" OD x 1-1/2" brazed diamond wheels in two diamond abrasive grit sizes (60/80 and 170/200 mesh or grit). Both wheels are manufactured to a low tolerance OD circumference run-out for maximum wheel life and to prevent pounding and poor performance during grinding. The high temperature brazed diamond bond provides excellent abrasive performance when grinding the rough shape of the gemstone material.
GP-6 CABMAKER OPERATION AND ADJUSTMENT tank. Also, don’t over force the gemstone material into the diamond wheel surface while grinding. Allow 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.
GP-6 CABMAKER OPERATION AND ADJUSTMENT POLISHING WITH DIAMOND PASTE The GP-6 Cabmaker comes with three syringes (5 grams each) of diamond paste in abrasive grit sizes: 8,000, 14,000 and 50,000 mesh. These diamond pastes are to be used with the three 6" OD Polytex polishing pads with adhesive backing on the foam covered convex 6" end polishing disc.
POLISHING WITH THE LEATHER BUFF PAD For final polished gemstone results, place the 6" cowhide leather pad (rough side out) on the foam polishing end disc using the 3M On/Off adhesive cement (red box) to hold the leather pad securely while buffing the gemstone in a rocking motion (Figs 22 & 23). Only use a small amount (8 to 10 dabs) of 3M On/Off adhesive cement on the smooth cowhide surface, smearing it uniformly before placing it over the foam rubber on the polishing disc.
GP-6 CABMAKER OPERATION AND ADJUSTMENT GP6 CABMAKER (PADS) MODEL The GP6 Cabmaker (Pads) model is identical to the GP6 Cabmaker (Belts) in that both models use 4" diamond resin belts with an expandable rubber drum to sand and polish gemstone material.
GP-6 CABMAKER Fig 27 MAINTENANCE Fig 28 USE OF 5" RESIN DIAMOND PADS Once the 5" resin diamond pad is positioned on the rubber or rigid backer pad on the right end of the shaft, adjust the Loc Line nozzle tip to the center of the resin diamond pad as close as possible to the center of the pad. This will allow the water stream/drip to flow over the pad while turning to cool and flush gemstone grindings during use.
GP-6 CABMAKER MAINTENANCE DIAMOND WHEEL/CARBIDE WHEEL REPLACEMENT When worn-out, the diamond wheels and expandable drum can be removed and replaced. For all models, first prepare the arbor shaft for removal from the body of the GP-6. 1. Remove the belt guard from motor mount (Fig 29). 2. Loosen the motor mount nuts, sliding the motor toward the polisher so that the belt can be removed from the motor pulley (Fig 30). 3. Unscrew and remove the locking knobs from the hood (Fig 31). 4.
GP-6 CABMAKER MAINTENANCE GP-6 (BELTS) SHAFT DISASSEMBLY 1. Use a wrench on the jam nut on the right side of the arbor shaft to keep the shaft assembly stationary and with the other hand remove the polishing hub by rotating it counter-clockwise. 2 Hold the expandable drum in one hand to keep the shaft assembly stationary and with an adjustable or box wrench, remove the jam nut on the right end of the unit by turning it counter-clockwise. 3. Lift the shaft assembly out of the bearing seats. 4.
GP-6 CABMAKER MAINTENANCE 6. Install the sanding drum with arrow of rotation facing direction of rotation (Fig 42). 7. Make sure grinding wheel and drum bushings are installed. 8. Install drive belt, retension belt (Fig 43) and replace belt guard.
