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.

Couldn't find the site I discovered a few years ago - even had some
pictures - but I did find these this afternoon after a quick google.

Combine this info with the fact that we can buy silicone casting
compound that lets us directly cast low melt metals like zinc and
pewter and I'll leave it up to the reader to connect the dots.

My only problem now is finding a source of the EPS beads again. One
of the local hobby-n-craft stores had them, but they went the way of
the missing web site.

I'm well aware of the lost foam and lost wax processes Leon, as well as
their limitations. Do you have any examples of something being cast as
complex as an air cooled cylinder head? Coffee cups, duck decoys, and alike
are useful items, but hardly good examples for the task at hand.
