INSTRUCTIONS FOR PRE–POLISHING
USING A COPPER LAP WITH DIAMOND COMPOUND
PREPARATION OF YOUR LAP
1.Smear several drops of liquid dishwashing detergent onto the surface of the lap and with small circular motions scuff the lap with some NORTON 400# wet & dry paper folded into a pad.USE ONLY LIGHT PRESSURE.
2.When the entire face of the lap has been scuffed, repeat the process but this time hold the lap under warm running water.Continue the process until all the detergent has washed off.
3.Dry the lap with paper towels and your lap is now ready to be and charged with diamond compound.REMEMBER: Wash your hands well before charging your lap.
4.With use the surface of the lap will glaze up.If you repeat the above process, you will be able to maintain a surface that will produce a very quick polish.
CHARGING YOUR LAP
1.Place the copper lap onto the master lap of the machine and, using a soft tissue, clean with a small amount of WD40 or mineral turpentine.It is always a good idea to place a piece of waterproof paper between your laps and the master lap.
2.Apply the 3000# diamond compound directly to the lap and distribute it evenly over the surface.For the first charge, the amount of compound to use on a 6” lap would be about the same volume as 2 match heads, a little more for a 8” lap.To minimise the risk of contamination you can spread the diamond compound using a soft white pencil eraser, mark this and keep it with your 3000# compound.
3.The lap is now ready for pre-polishing.Remember not to use too much pressure as this will only wipe the diamond compound off the lap.Several firm strokes across the lap will give the best result.NOTE: This is still a cutting action so some gem material will not start to develop a glazed surface at this stage.
4.If the lap dries out use some extender fluid to moisten the lap surface, use only a very small amount.As you continue to use the lap you will need to apply a little more diamond compound when the cutting rate slows down.NOTE: Remember to always only add a very small amount of diamond compound.
5.The more the lap is worked from new, the more it develops a slightly “hard” surface, until it will get to the stage where you will need to clean the lap completely and once again recharge it.
