THIS LIGHTWEIGHT DEVICE, A TRIVET, IS DESIGNED TO PROVIDE PRECISE, REPEATABLE, INDEXING OF THE "GEOSTEP" (SEE "GEOSTEP" TECHNICAL DATA SHEET) OR OTHER C.M.M. CALIBRATION DEVICES. MOST OF THE HARDWARE USED IN THIS SETUP ARE PART OF OUR OFF THE SHELF LINE OF COMPONENTS. BY USING THESE STANDARD COMPONENTS, THIS RATHER SOPHISTICATED DEVICE CAN BE PRODUCED FOR A VERY MODEST COST.

OUR STANDARD "14-INCH TRIVET" IS MODIFIED TO BECOME THE UPPER ROTATING HALF OF THIS KINEMATICALLY POSITIONED INDEXING SYSTEM.
