Re: flat lapping help....
I came here to get help with flatlapping some time agoe and got some good help so this may help you too. The wax trick works. I keep cleening as I go to keep the grit in the pan and use an old toothbrush to wet and brush off back into the slurry as is builds up. I use high presure water to clean out any cracks too. The biggest thing about using silicon carbide grit is that one speck carried over to the next step will scratch your polished slab. I have used rubber bands to wrap around the bace of the slab to keep them from chipping together when two or more slabe are in the pan. Another trick is to make a weight to put on top of your slab to speed up the lap. use modeling clay to keep the weight on. I fashoned a plastic bowl as a lid to help keep the moisture in the pan as well and the slurry doesnt dry on as hard and comes off with little work. Use a GFI on all electric tools that have liquids in use to prevent an electrical shock. Mike
