Hello everyone, I've searched the forums, read hundreds of posts, gathered tons of info, made a plan, registered here, done the intro in roll call & now it's time to get down to business. This is my first build, so any and all input is appreciated. At the end of this post will be a pic of what I'm looking to achieve. The Rules: 1. Build on a limited budget. I have taken inventory of the materials I have on hand and have based the smoker size on this inventory. I will only buy something if I absolutely need to. 2. This is to be a vertical direct smoker (not reverse flow). 3. Have fun and learn. The Build Plan: 1. The overall size of the smoker will be 24"W x 24"L x 36"H. 2. The cook chamber will be 24"W x 24"L x 26"H. 3. The firebox will be 24"W x 24"L x 10"H. 4. The construction will be 1/8" plate steel for the entire interior (cook chamber & fire box), framed with 1 1/2" x 1 1/2" x 1/8" wall tubing, insulated with 1 1/2" thick Roxul and skinned with 1/8" plate steel. 5. The plate between the firebox and cook chamber will be 1/8" plate steel as a minimum. If I have 1/4" plate, I will use that. I do not plan to have a built in drip/water pan, but will use disposable aluminum pans for this. If I have enough material, I may incorporate a built in pan. The Questions: 1. Are my cook chamber to firebox ratio adequate? I've read that for a VDS, around 25% for the firebox is good. 2. What would be a good firebox intake size? I was thinking of a slot type that is 3"H x 12"W centered on the side. 3. What size and length should my chimney be? I have tons of square tubing (5x5 & 6x6). 4. Should the chimney be right on the top or exit out the back at the top (I hope that makes sense)? Thanks in advance for any and all input. This is the style I'm wanting to build.
