A TRACER SYSTEM FOR DETERMINING GEOMETRICAL SURFACE DIMENSIONS OF WAVINESS AND ROUGHNESS OF A WORKPIECE SURFACE AREA COMPRISING TWO PAIR OF TRACER MEANS, THE AXES OF ALL THE INDIVIDUAL TRACER MEANS BEING PARALLEL TO ONE ANOTHER, EACH PAIR OF THE TRACER MEANS CONSISTING OF TWO ELONGATED TRACER MEANS INCLUDING ONE HAVING AN END OF RELATIVELY LARGE RADIUS AND ONE HAVING AN END OF RELATIVELY SMALL RADIUS, BOTH PAIR OF TRACER MEANS BEING MOVED SIMULTANEOUSLY AT EQUAL SPEED ALONG THE WORKPIECE SURFACE, THE INDIVIDUAL TRACER MEANS OF ONE PAIR OF TRACER MEANS FOLLOWING A COMMON TRACER PATH AND THE INDIVIDUAL TRACER MEANS OF THE OTHER PAIR OF TRACER MEANS FOLLOWING ANOTHER COMMON TRACER PATH, THE SAID COMMON TRACER PATHS OF THE TWO PAIRS OF TRACER MEANS BEING PARALLEL, AND EACH INDIVIDUAL TRACER MEANS BEING AXIALLY MOVABLE INDEPENDENTLY FROM ONE ANOTHER TOWARD AND FROM SAID WORKPIECE SURFACE AREA AND ARRANGED IN SUCH MANNER THAT ONE OF SAID TWO PAIR OF TRACER MEANS HAS THE ELONGATED TRACER MEANS WITH THE SMALL RADIUS IN A LEADING POSITION WHILE THE OTHER OF THE TWO PAIR OF TRACER MEANS HAS THE ELONGATED TRACER MEANS WITH THE LARGER RADIUS IN A LEADING POSITION, AND MEANS CONNECTED TO EACH PAIR OF TRACER MEANS TO RECORD A MEASURING VALUE ONLY WHEN THE TRAILING TRACER OF THE PAIR HAS PASSED THROUGH THE TRACING PATH OF THE LEADING TRACER MEANS OF THE PAIR.
