If you can reference any hobby process that will made it "simple" to cast
custom air cooled VW heads at home. I can assure you, I'm not the only
person on this group that would like to see a link.

I'd never have thought this technology was that obscure :-) 'course
it depends on your definition of "simple". You have to make or buy a
whole bunch of new tools and learn a few new skills if you have never
done it before. Kind of like making an airplane from a pile of raw
materials (the token aviation reference)

To me it's pretty straight forward use of patterns and molds, but then
again I had the good fortune of my grandfather showing me how to make
molds and fire porcelain things just shy of 50 years ago. We could
have made VW head molds back then using nothing more sophisticated
than some clay, plaster and green soap. The materials available
today make the process MUCH easier.

Fire up Google and see what others are doing.

My first exposure to hobby foam casting came from such an adventure
and was found of all places on a site run by a den mother describing
how to make foam trinkets for the kids to paint. If some 8 year old
kids can do it.......................

Not the site I had in mind but this is using green sand - with enough
detail and complexity for a VW head.

I've also been keeping my eye on a couple of interesting projects
being pursued by "Why Not!" types trying to build inexpensive 3D
printers. Think what we could cast up with one of those out in the
garage.
