This model illustrates the principle of a screw cutting attachement used on almost all lathes. The rotation of the drive shaft is transmitted via a simple gear train to the driven shaft, which in this case is a threaded spindel. The support block on it slides along and carries a pencil to draw the helical line on the circumfence of a drum fixed on the input shaft. Up to the choosen gear ratios between both shafts different leads can be obtained.
