Wanted to share a back yard smoker/grill I made for a friend of mine. He said he was getting tired of buying the smaller smokers only to keep replacing them. I've been wanting to make a smaller back yard type and put this one together for him. Used a 60 Gal Pig Tank and cut down a 40 gal for the fire box. Made the cart out of 4”x4” tube with 8” solid rubber for the back tires and 4” swivel for the front. Used the calculator for the design and when I did the burn all was excellent on controlling the temperature. He is moving so it will be a few weeks before he makes the maiden smoke off. Hope you like it. Tanks used for build (cut down the one used for fire box): Built cart to mount smoker. Air Inlet and used same on fire box. Clean out and ame type on fire box. Mounted fire box and side view. Front handle and shelf. Inside smoker rack. Completed Project!
