I was browsing smokers today... I liked one... it was $7k... not today.

You learned them welding skills in Mr Gentry’s class at Magnolia High School ?
Never had him, but I definetly had quite a few days of stick welding beads during shop class.
I honestly can't believe some people actually passed those classes. They had zero mechanical abilities.

I wish I learned to weld.
Mig welding isn’t that hard to get a functioning weld but then you have guys like CaptJJ and what they do. Those welds are works of art. Tig welding is a whole nother level.
My son is friends with a guy who works at the Navy ship yard in Virginia. He said a good portion of the welds he does inside of submarines is done with mirrors. Imagine trying to weld looking in a mirror. I get cross eyes thinking about it.

What you don't see with Moberg is the angled cut of the firebox into the cooking chamber. There is a reason he doesn't and doesn't allow people to post pictures of his firebox to cook chamber. Got the idea from Austin Smokeworks and they do the same regarding pictures.
You can't make out that much, and the design may be different on his commercial cookers, but Moberg actually let a YouTube channel video one of their backyard pits a couple years ago.
I actually got the idea of putting in a radiant heat shield plate from the video.

Here are some photos of his backyard smoker design.


You can see my plate here: (I hope it tames down firebox-side hot spots a bit, but who knows)

Looks good man!
As for a finish, boiled linseed oil is the way to go. Use flack seed or grape seed to season the inside. But on the outside, bake on boiled linseed oil. Heat it up with a rose bud or a weed burner and wipe it on when it's at about smoke temps. It will actuwly harden on there and give a good weather proof finish. It's easy to touch up down the road vs trying to keep high heat paint looking good

Use to do some boiler tube welding and did the ship yard piping too. Tons of mirror work, having to feed the tig wire though the open root of a pipe joint.
Part I always had the most trouble with was when having to switch from right to left hand when working off a mirror and trying to work the hand amptrol on a tig torch. Don't care how many times I did it, I would have to sit there and think which way to roll the amptrol when using my left hand. Plenty times I'd be finishing up a decent weld, go to daily off the hear and instead crank up on it and blow a gaint keyhole out. Don't really miss any of thay

That's the video he did with Max, and it was still very selective on what he showed. I've never looked in one of his backyard cookers, but I'm almost positive there's an air gap between the firebox and that deflector plate. Which would make sense why it's welding on the grating angle iron and not directly on the firebox. I can't really tell if that's how you did yours or not. It's almost a play on how Lonestar Grillz does the convection on his 20" pits.

I put an air gap in mine as well. The square box into the cylinder tank actually lends itself pretty naturally to a gap there.

Hell most dang water heaters are stainless thin but free! But a good excuse to buy a tig welder

Columbia, what river is that? Interesting rock strata and beautiful water.

Really can't believe how much oiling the pit helped bring the finish on it.

How is it holding heat? The one I’m building I’m fighting with the door to try to make it as sealed as possible. This thread inspired me to build one. I need to weld the legs and rollers on it then try it out.

Mine only leaks a small bit around a couple corners in the door, and I mean a very small bit.
The trick to getting the doors to stay sealed is how you cut them. Don't ever cut out the corners before you have your hinges welded on.
Once the hinges are in place, put on your flat bar (as much as you can) and then cut one corner ar a time to release it.
As for the rest of the cooker, I've never cooked on an offset this big, but it seems like I am going to need a hell of a coal bed to get it up to temp.

Once you get the metal hot, if it drafts properly you shouldn’t need much at all. I bet you could run quarter or At most half of a split and get steady temps.

First real cool tonight.
Naturally sits at about 225 w/coal bed and between 275-300 when 2 small splits are burning.
My old one was an absolute nightmare to keep at temp. Would swing either 350+ or death fall to 180 as soon as the flame stopped. (Had a small 16 inch cook chamber smallish, uninsulated firebox, and no real thought behind the design).
Couldn't be happier with how how it turned out.
Probably have close to 150 hours in it (at least) and about $600-$700 when all said and done. Can't complain.
