>Vibratory laps aren't 100% hands free. You have to make sure thy don't  dry

>reduce  evaporation.
>They also round the edges and will wear a little into softer  spots in the
>slab.

>If you can possibly find one used, there's a machine called the
>Rockhounder's Paradise. It is a dry lap using 18 inch floor 
>polishing discs  that are only
>$3-4 at most rental places. It has two chambers about 8 inches  each that you
>can put your rock or weighted slab in. The chambers are designed  to rotate
>the rock at the same time the 18 inch disk is rotating too. 
>The  slabs come out
>dead flat and a mirror polish.
>
>You have to break in the polishing disk so it's worn enough to polish,  after
>that it can take as little as 5-6 hours to get a good polish. You glue  the
>polishing disks to an 18 inch metal lap with Elmer's white glue, then soak
>them off in a tub of water when you need to replace them. A disk will last
>several slabs though. The machines haven't been made in a number of 
>years and  the
>older units with low serial numbers are better than the newer ones, 
>after  the
>original guy died and his son started making them. I'd look for a  serial
>number less than 600. Obviously, since it hasn't been 
>manufactured  in close to
>20 years, I have no ties to the manufacturer.

>Hope this helps....
