does anyone make there own molds if so how and with what?

[sagacious]

This is quite a formidable question you're asking! There's an awful lot that can be said about mold making. Perhaps if you narrow your question down a bit, someone can shed some light on your query.

I'm interested in this question too. Does the mold have to be aluminum or can other, more user friendly materials be used.

I'm experimenting with resin with micro balloons at the moment (I've got 15Kg of the stuff, got to use it somehow). It seems to work OK, but I don't know the effect of large numbers will have.

I know there are high temp RTV's around. How good are they? Do they have a reasonable life span? Will they do 200 or 2000 or 20,000 pours.
