One of my car digests noted yet another sign we are all living science fiction: E-machine shop.com, the first company (that I know of) that makes all those hyper-fancy computer-controlled machine tools available to just about anyone. All you need to do is create what you want in their (supposedly) easy-to-use software, send it to them (with a check, of course), and a few weeks later your part arrives.

Alfa Romeo is world-famous for requiring a whole chest of custom tools to do any real work. They are, of course, no longer available, but maybe with this service and the right plans...
