[TheForge] A blown, fuel-injected forge

[Mike Porter]

Frosty,
There are both metal and refractory nozzles available for blue flame oil 
burners today. The refractory last longer, and is also quite a bit more 
expensive the metal nozzle, but they are both consumables. If you are saving 
big bucks in oil consumptions they are certainly worthwhile, but for the 
hobbyist, I think not.

Three years ago, there was quite a bit of talk on Hobbicast about a double 
chambered oil fired casting furnace too. The idea was to use a normal oil 
burner in conjunction with a superheating chamber to get a clean burn; lots 
of talk, but no follow up as far as I know.

>> Jerry,
