First time offset smoker build

Hey guys. Finally decided to pull the trigger and make a smoker. I used feldon's calculator to come up with the pipe dimensions. I am using 24" pipe 40" for the smoke box and 14" for the firebox. The firebox pipe is 1/4" wall and the smoke box looks to be 5/16 but it is a bit pitted so I would guess 1/4 in the thinnest areas. The firebox looks a little small to me, but I figured I would follow the calculator now and then if/when I make another one adjust it to my liking.

I did some CAD work the last few weeks and finally decided to pick up metal and start on it the last couple days. I am using 2x2x1/8" for the frame. I wanted to cope the tubes to fit the tube well. So I 3d printed some jigs to help with coping worked out pretty well. and got the fitup i wanted.

Got the frame fully welded up.

Here is the smoke chamber mounted on the frame and firebox sitting next to it so I could see how it would look

Lastly cleaned up the smoker with wire looks a lot better. Debating if I just want to keep it oiled or actually paint it.

So this is where it stands now. Next steps I want to do are to cut the smoke chamber door. I need to pick up some 1018 and machine some hinges that I designed. And then a decent amount of plasma cutting and welding. Not sure if I want to fully tig everything or go in and finish all the heavy stuff with the stick welder. Hoping to get a lot done mon-weds this week.

Looks like you are off to a good start. I’m a bit concerned with the length and diameter of the firebox. I think a smaller diameter longer piece might work a lot better for you.

Looks great, I would have to build a 2 piece door on the fire box, separated in the lower to middle so when you open it to add wood the coals wouldn't spill out , nothing wrong with trading length of it to height but a air leak will let the temps run wild with a vertical stacked fire, similar to a gravity fed cabinet.

Yea thats what I was worried about too. The metal yard I got the pipe from is looking for some right now, not sure if I will be able to find a piece for the price I want to pay though.

If your local supplier can’t get you a piece of pipe that is smaller diameter you could ask a metal shop to roll you a piece or make a square firebox.

What is a good length firebox to aim for?

Also is it more for fire management? Or does a longer firebox help in other aspects?
