heres a project ive been working on. its a 55 gallon drum. it will be and almost is a smoker now.first thing that done is a burn out. to burn and remove any polutants inside of the barrell. you can use a drum lid but to add space i am using a salvaged old weber kettle lid. a lil modification and rolling of the metal was needed to make it fit. i used some fork horn deer antlers my friend left me to make a jackalope i never got to do. and a fresh coat of high heat muffler paint.
