Well this will be my first post for the forum. I have enjoyed the past couple months reading every ones build and recipes preparing myself for this project and I want to thank everyone alot. Could not have done it without everyone else sharing their ideas. My build is a 30" diameter 3' tall Stainless steal barrel. I'm mounting this on a fire box that i made out of the bed of a Kawi TERYX. The fire box is 3'x3' and a foot tall. Inside the box i will mount a charcoal basket on a slide out rail that will be 2'x2' 8" deep. Rack are going to be 3- 29" diameter circles mounted on a roller system so they will act more or less like over sized lazy susans. insulation is 1" thick Kaowool that i picked up off ebay. This is insulating the bottom of the firebox. I welded a sheet of 20ga steel to cover it. This is the outer wall assembly on the fire box. 20ga steel sheet and 1" angle iron for the frame. insulating the walls on the firebox. Worked out the spacing by using the same 1" angle for the depth on the kaowool fire box just about finished... just have to add the insulation and top cover piece ( its going to be 1/8" steel) This is about what it will look like when its all said and done. I will insulate the cooking chamber before i'm finished. My door is going to be 18-20" wide 3' tall and will hinge up and be held shut assisted by gas shocks. (stole that idea from a gentleman who did an insulated vertical build with the nicest glass stove door on his firebox). i will have a 15" square water box between the fire and smoke box, Also my exhaust is going to be 5" diameter mounted on the top. It will be controlled by a butterfly valve and i'm not sure how long it will be yet. I bought a chrome stack off of a semi truck for 25$ and its 6' long, but i will probably cut the stack down to 4'
