Group, The following text are the instructions for the "Talkie Amateur Crystal Grinding Kit."
The abraisive mentioned in the text appears to be a carborundum powder - the stuff can be had at a gem / mineral shop. INSTRUCTIONS FOR GRINDING EQUIPMENT One plate glass at least 8" square. Abrasive (enclosed in kit), two pans of water, one pan of soapy water, two wiping towels. PROCEDURE Prepare a mixture of abrasive and water about the consistency of syrup on the plate glass. Place the face of the crystal blank in this mixture. Adjust the ball of the forefinger or middle finger on the upper surface of the crystal, or you may get better results by using the fore-finger and the middle finger together dividing the surface of the blank between them. The position of the hand must be parallel to the plate. With a flat light pressure on the crystal, start a figure 8 movement about 6" long. Repeat figure 8'about ten times, make a 1/4 turn of crystal,repeat ten figure 8's, another 1/4 turn figure 8 etc. When approaching frequency cut down number of figure 8's, ten figure 8's should take off about one KC. Often in grinding the surface the strength or oscillation will fall, to regain it work the edges of the blank by holding it upright between thumb and forefinger. Tilt edge at about 60° angle from the plate glass, make about ten long oval strokes and repeat this on all edges. CAUTION: LIGHT PRESSURE ON ALL MOVEMENTS When desired frequency is reached wash blank thoroughly, sponge dry on a lint free towel, place between the electrodes and case in holder. __________________________________________________ Do you Yahoo!?
