hello I was wondering how you make a mold. what are the processes and what is needed. also how expensive is it?

here's the deal.... I've broken a gear tooth and it takes forever to patch, so why not just make a new one? I could just take the plastic and melt it into the mold, comphensating for the missing tooth and save a few bucks. also I've seen people make molds for camera mounts and thought this could become quite useful as I could even go into the depths of making new frames and skids which brake quite often, or make new rotor heads and such (four bladed/3 bladed) and could have a lot of fun. I'm sure many of you woudn't mind doing the same thing either. (hey think of it this way you could make your own coustom canopy shape)

I was thinking mostly plastic which should be easy to mold but if I got really into this does any one know how to make aluminum molds?


just a good thought, thecheat
