The work table is graduated 360º 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 4º. 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. Both the upper and lower surfaces are precision ground.
