I'm not exactly sure what this is called, I seemed to recall someone saying it's a Diamond Demon?  I purchased it a few years ago and never really had the time to play with it until recently.   I had been trying to purchase a flat lap but realized I could probably just use this instead since I already have it.  I purchased it at a Faceting Guild summer flea market.  It came with a lot of pads of different grits, etc.  What it didn't come with was any kind of water supply.  I would also like to get some of the missing grits but I have no idea where I would find them.  Does anyone know who would supply missing parts for this?

Thanks as always for your input!

You will have to figure out some plumbing, but I know you can get an inexpensive water pump at Harbor Freight. They make a really small one that goes in miniature ponds, etc. and I think it is only about $15.

A water pump would supply much too much water to the cutting surface . Too much water equals a huge mess and very poor cutting as the stone hydroplanes across the surface .A piece of small diameter copper pipe can be bent into the shape needed to deliver the water flow to the laps. A bucket on a shelf above the machine connected to the copper distributing pipe will provide more than adequate water if  standard aquarium  tubing is used . The machine should take one of the standard lap types so you have a choice of lap manafactuers . Take a lap off the machine and show us the lap. I used this machine a bit many years ago in some one elses shop and found it very good for efficient sanding .

For what ever water system you decide to use........put in a water volume control valve to regulate to flow as necessary.................. yes
