The FB is a (propane tank) 1/4 inch thick and everything I have read said this was the go to thickness.Dirtytires wrote:You can insulate all sides without a problem. I did all 6 sides of mine included a double walled/insulated door.
Just something to consider... your tank is most likely fairly thin and can be the weak point in a smoker. The heat cycles and ash abuse the firebox a bunch. Many take this into consideration and plan to cut off and replace the firebox when it burns thru. I mention this just so you are aware and can make an educated decision on replacing the firebox vs buying heavier steel now. It’s a tough call but given the choice, I would probably go heavier steel with my budget and not insulate. Your materials seem to be free-bees tho so I see your current direction has positive points as well.
Either way is going to work out just fine...
It’s called funds and I’m limited. I already need 1 sheet of 1/4 for the plate in the pit for the RF plate at a price of 225 dollars a 4x8 sheet, if I make a square FB that would be another 225$. I can spend less than that with the cylinder and can insulate and still have a little left over of the 225. I have a cylinder on my small pit and it is a little pain but not to bad, but I get where you’re coming from.bstory wrote:Just my opinion, but I would consider making the entire firebox out of plate and make it all square and the place your cylinder on top for the warmer. So if you are doing insulated, build a square firebox to the specs needed and then an outer box to hold the insulation and inner box. The round FB is a pain in the butt!!!! I promise from loading wood to dumping ash during a long cook. They work obviously because you see them everywhere, if you are going to buy plate to put around the cylinder I would just buy enough to make the entire FB square. My first two smokers I built, I made round fire boxes using part of the tank and they just suck. I will never make anything other than a square firebox again. And you will not be disappointed with an insulated firebox, man it’s awesome.
