I have been meandering around looking at all the different type smoker builds and this past weekend I started on my first smoker build. I'm using an old 130lb propane tank (I made sure it was purged before I started cutting) for the cook chamber and an old air compressor tank for the firebox. This is what I have got done so far. I used the Feldon calculator to size my fire box and smoke stack. I am not a welder, so just look past my ugly welds, nor do I have any experience fabricating. But I watched my dad for years welding on tractors and other machinery so I have a good grasp of how to weld. I hope you enjoy this journey that I am taking. Cutout my doors but left the corners attached so that I could add hinges. I got the firebox welded to the cook chamber and now I just need to finish my stack.
