How far back should the burner be, for a single burner forge? Dead center, more toward the front, but angled back, or in the back angled slightly forward?
Also, I was reading your book on building a 3/4" burner, and it said to make four slots for the air intake. I thought I had read on a post, here at IFI, where you said the updated version needs 3 slots. I can't find that post anymore, is that correct, or am I confusing it with another thread?
