I am not up to date on the size requirements on these as I have never built one out of metal but there are a ton of guys on here who have and know all the questions you are asking. I believe there is even a thread I saw a while back that has all the info. I will look for it. I will bump this up and hopefully someone will give you some help.

Also as I remember from reading many build posts you need to make sure your fire box is a certain size or you won't get the heat you are looking for. Don't quote me on this but I was thinking that the fire box needs to be around 1/3 the size of your smoke chamber or something like that. There is a formula but I can't find it yet. I may be way off but someone will know for sure. Just didn't want you to put a tiny box on there and have issues.
