Creating molds

FSM, May, 2005.

Bare Metal Foil has an online tutorial.

One thing I don't think either mentions enough is that you must have a separate air channel from the lowest point in the mold cavity to the top of the mold, especially with small parts (like 1/42 or 1/72 figures or parts thereof.) The only way around this is a vacuum molding set up. If you can pull a vacuum on the mold before the resin starts to set, you don't need the channel.

I found this out the hard way… (a figure's legs are not enough.)

That's the one.  IIRC they demonstrate how to make the mold, then show about creating the part.
