Well it's standard old gagemaker's tool. You put the diamond conjoin on a steel plate (used here as an anvil) and lay a conjoin of flog with a hit over the top of the diamond so the diamond is in the hit. Then you put a piece of paper on top and rap away. The diamond chips are trapped in the hole in the flog and the cover keeps them from flying around.
Then you take the diamond grit pour it into a store of olive oil and move it up. With a pipette you draw off the diamond as it settles to the furnish. The coat of the grit relates to the measure you let it lay; I forget the drill but you displace it off into different vials and let *them* lay. Then you charge a lap with the coat that settles to the bottom of the vials selecting the coat you want.
That's also how precision toolmakers used to make internal grinders for precision internal grinding for making master jigs and so on boring and grinding them on a lathe. Instead of a lap the grinding tool was a mild-steel.
