Detail Man

Sounds like you are getting too much O2 in the fire can you adjust the choke on the burner?  What hind of "dragon's breath"do you see with the forge running? (the exhaust plume coming out the front of the forge---tells if it's reducing, oxidizing, neutral.)

Would you please elaborate on the "dragon's breath"?  What do reducing, oxidizing, neutral plumes look like?

So did you get your drift made? Which of your materials did you decide to use? How did it turn out?
