Neater still would be an air bearing arrangement. Tighten the table down hard with belville washers. When you want to rotate it, apply compressed air to the holes drilled in the mating face that I forgot to mention earlier so it rotates on a minimal thickness air-bearing. To clamp, turn off the air. In case you doubt that this will work, it was how we clamped the tool height adjusters on the testing machines I used to design. They were for knocking balls off of ICs, and pulling out the tiny gold wires from carrier to die. You were working under moderate magnification and still could barely see the tool move as the air went on and off, the clamping force was enough to scrape entire dies off of substrates, but the sliding force when released was enough to not even mark the substrate. (the process was release, land, clamp, back off a few microns) -- atp ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the facts. http://p.sf.net/sfu/google-dev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
