So I have an Economy Side Fire Box Pit that I no longer use much for grilling. (Got the Weber Summit 6 grill with wood basket that I use for grilling on now.) Anyway, I was thinking of modifying the Brinkman to be more of a box smoker. Basically removing the door from the main pit. Attaching Aluminum angle to the existing legs about 5' high with some side bracing. Then adding aluminum sheeting for the walls and ceiling, making a box. Use the existing chimney off the Brinkman at the top of the box that has a dampener for the new chimney. Could add sheet insulation to the outside of the aluminum sheet to conserve heat & seal w/ aluminum tape.
Not sure if the firebox would provide enough heat for this large of an area, but I could always use the bottom of the main pit if needed. I process my own deer meat and want to be able to hang about 50lbs + of sausage links and smoke. It wouldn't look all that pretty, but I don't care about looks, just want something functional and cheap. I have all the aluminum already so I wouldn't be out much as far as materials go.
