Abstract: An insertable multiple stop indicator gauge for selective height, depth and workpiece platform control as between the tool and the workpiece is disclosed. The multiple stop apparatus is detachably attachable to a milling machine tool carriage and to a screw shaft operably secured to the travel of the carriage, the carriage including upper and lower casting lips, the screw shaft including an adjustable knob threaded on and about the shaft and further including a carriage stop threaded on and about the shaft, but above the adjustable knob. The present inventive improvement comprises an insertable lower stop platform for controlling depth of tool cut in the platform in which the stop platform possesses one fork-like end detachably attachable to the lower casting lip and securable thereonto by the adjustable knob, the lower support platform having a circular opening in its opposite end.
