The brake drum had a 1/4" lip on it and i hung that lip over the giant circle i had to cut (with an angle grinder) in the 1/4" plate I supported the fire pot in. Then I just welded that lip to the plate. Believe me, that fire pot is IN there! No heat could take that out of there, xxxx I'm not even sure a direct nuclear hit could take that fire pot out of there. lol
I somewhat followed this design. See attached photo.
The tweer is 6 1/4" holes and it puts about a 3" or 4" area of airflow right in the middle which seemed to be what people were saying in the stuff I read. My only conern is that I may have to make a new tweer that fits into the inner bottom of the brake drum, instead of covers the entire bottom so I can get more depth out of the drum itself. Cause I think I might be a little shy on depth with the tweer and grill. But i'll have to see when i fire it up.
