Ha! Or not... Getting the necessary accuracy and tolerances will be very difficult and I would not recommend barreling into this project before doing some serious research.

We made a worm-gear drive this year out of a piece of 1/8" thick boxed aluminum and a bronze spur and stainless worm from Applied Technologies. I would NOT suggest buying from McMaster Carr. McMaster only sells cast iron worms, which will turn to dust after a few matches.

If I were you I would spare myself the grief and buy a contained unit such as these:

If you have the resources to machine a gearbox I'm sure you have the resources to cheese-hole one that’s already made

(You can see the gearbox on the side of the T. REX's arm)
