Hi Tim,

That is a tall order. Kinda like saying I'm new to model railroads
and want to know everything about engines, so please elaborate on
every detail. :)

My first comment would be to find out how large a block you would
need to use to make a mold. That would dictate the work area for
your potential machine.

Rong-Fu makes a table top milling machine that can be CNC'd, or if
you wanna go top of the line in retro-fits, a Bridgeport may be found.

If you can live with a lot smaller footprint, the mini-mill may be a
good choice.

I think that determining the work envelope is the first order of
business.

Then, google a machine like Rong-FU and CNC to read what others have
done.
