Thanks for your input Jeff. Where do you recommend I buy graphite from?

Graphite would probably be the most affordable of materials to use.  We had a 
machinist in our local group at one point and he made a titanium nozzle as a 
proof of concept.  That would more than likely be rather pricey for this 
project ( his was for a 54mm motor).

Aluminum is a good material to practice on or do mockups with, but I suspect 
that it's melting point is way too low to be used as the actual nozzle.  It 
might work as a carrier for a graphite or ceramic insert though.
