I am new here and green as grass. I thought the fire pot had to be cast iron for some reason. Yours looks like welded steel. How thick is the steel you used? I have been looking for a forge recently with no luck. Let me rephrase that "I'm CHEAP". I could make what you have there for a little bit of nothing.
I saw a video on one of these sites where a guy used a brake drum for the fire pot, actually it looked like a recessed rotor for disc brakes.
Any info you could give me would be greatly appreciated.
Paul
