For a little project I need to use a worm drive, and the best/ cheapest solution seems to be one like this designed for modelmaking. But how do I fix those gears on the shaft/ Axis? Am I supposed to mill a key in it or something like that? I have a Dremel, so I could carve something in the gear, but not in the worm. And then I would need a shaft with a fitted key and those are expensive. Or are they designed to heat-shrink them onto the shaft? Unfortunately there is no information on the site.
