The following series of photographs were taken as Jay Wakefield, who assisted me in Puma Punku, used my surface gage to inspect the flatness of one of the stones. A lens magnification view was applied to a circle around the dial indicator and is inset near the dial. The movement of the indicator dial around a 360 degree arc was less than the .0005 inch resolution of the dial.
