hi ! my name is jimmy im from sweden,this is my first post here and im a total rookie on bbq so please have patience with meand my english
i was planning to build me a UDS but i found this smoker half done at the recycling staion took it home put a door on it ,som air valves,handels cooking grates charcoalbox etc,made som ribs in it and it worked ok,
now im planning to ad a firebox below it but im not sure how big it should be? my plan is same width and lenght as the smokehouse? and 12 inch"high".then it would be 20x12(?) roughly (hope you understand what i mean my english isnt the best)and a charcoal box that is about 8x20 than i have 4 inch for airflow,and how big should the opening between the firebox and the smokehouse be?should i just open all the way and maybe leave an inch all the way around?
im thankful for all the input i can get!
