Worm and Worm Wheel: a Steel Screw and a Hobbed Bronze Wheel
A worm is a screw that drives a toothed wheel at right angles; with a single-start worm each turn moves the wheel one tooth, so a 30-tooth wheel gives 30:1. Cut the worm on a screw-cutting lathe, make a hob that is a copy of it with cutting edges, gash the bronze wheel on the dividing head, then run the hob through it to finish the teeth.
The picture: a worm shaft with its bearings and a hobbed bronze worm wheel from a gearbox.

Cut the worm
Cut the worm
Turn the steel bar to the worm's diameter and set the lathe's change gears to the axial pitch (π × module). Cut the single-start thread with a tool ground to the tooth form, checking it with the gauge.

Make the hob
Make the hob
Cut the same thread a little oversize on tool steel, file four or more lengthwise flutes across it to make cutting edges, back off behind each edge, then harden and temper it.

Cast and turn the wheel blank
Cast and turn the wheel blank
Melt bronze in a crucible, cast a round blank, and turn it on a mandrel to the wheel's diameter with a hollow rim to wrap the worm.

Gash the teeth
Gash the teeth
Mount the blank on the dividing head with the cutter path set at the worm's lead angle and cut a slot for every tooth, nearly to depth.

Hob to shape
Hob to shape
Run the hob in mesh with the gashed blank, free to turn, feeding it in gradually to full depth: it drives the blank round and generates the true tooth form.

Worm drive principles, gashing and hobbing are as Wikipedia describes them; the module, tooth count and making the hob from the worm's own thread are ours. A single-start set like this is usually self-locking, which depends on lead angle and friction.
