Anyone make their own carbon fiber parts?

[XcYZ]

I'd like to learn how to make some small non-structural carbon fiber pieces for my project (ducting, etc). I've know plenty of guys have done it (I've seen home made computer cases, RC airplane parts, etc) but where do I start? I know there's different ways to impregnate the resin such as vacuum or use pre-preg CF (but does pre-preg only come in bulk?). Obviously I don't have an autoclave, so I'm interested if anyone here has made their own molded CF parts and what resources you used.
