The work table is graduated 360 degrees around its circumference and is driven by a precision Worm and Gear providing a 90:1 reduction ratio. One turn of the Handle moves the Table through 4 degrees. The dial is graduated in divisions of 1 min. and the vernier scale allows readings down to 10 seconds.

The Worm is hardened and precision ground to minimize wear out of the WORM GEAR.
Both the upper and the lower surface of the ROTARY PLATES are precision ground.
