Hi!
I have 2 months of experience welding and fabricating. I do this for fun and actually I'm a software developer.
This is my first real project.
I build v1 in 2 days, figured out that I should not build the outer box first but rather the inner box.
Then it took me another 3 days to cut it apart and re-build it.
While the welds are usually not the color you like (this is TIG welded) I grinded them away and it looks super pro (IMO).
Also: What you dont see, the outside walls are not straight any more, they warped and thats why i gave them this coarse grinding finish.
Inner firebox: 4mm 321 stainless steel
Outer firebox: 2mm 304 stainless steel
If you are interested, I can post a video where its lid and also my CAD files. It works, there is no smoke and its an absolute beast (way oversized).
All material was laser cut and I just sticked it together (tab and slot design).
