I am new to the forum and I have to say this site is great! Also thanks in advance to everyone who chooses to be patient with my many questions and for the knowledge you will share with me! I know I want to build my own smoker, I know that I want to smoke with wood. I know that I want to build either a small smoke house type of chamber maybe around 3' w x 3' L x 4' T. OR do a refrigerator conversion. I know I want a firebox separate from the chamber. that the smoke is piped in through some sort of venting system. those are some vague parameters, I understand but that's Kinda the Ideas I am leaning tword. Lets start with these questions. 1. I want to have a wood source, I see a lot of builds using either propane or an electric element, is this standard on a smoker? Is it necessary? 2. What can I use for a firebox? I see a lot saying not to use galvanized metal, I was considering a 55g barrell? 3. If I choose to do a refrigerator conversion, How does that exactly work? would the inside not melt? I understand that you have to deconstruct it mostly to the shell but it looks like from what I have seen that most of the insides are still there, are they not plastic? these may be rudimentary questions and seem stupid and I would like to think I am a fairly smart person. I just want to make sure that I am doing this right. If I put the work In I want it to work!!! Again, thanks in advance!
