Hi Guys, newbie poster, but a long time looking on from the edges! We use a 7" diamond cup grinder fitted to the arbour of our 9" Hitachi angle grinder- it does the same thing as the auto-polisher but at about four times the work output. I recently bought a Hilti DG150, which does the same thing but even faster. It will even grind down the stones skewed facets to leave it flatter for laying. Maybe that is of some use to you. Routing the stones requires a massive clamping force and feed pressures and would be impractical in the field.
