As you've seen, the stove looks very nice and works even better.
I think this construction is much better than the previous one. I used other solutions and better materials which gave me an interesting effect.
I bought rims at the junkyard, they were not fit for use because they were bent.
I used large rebar to make the grate. I am sure that they will last for at least a few years, especially burning "from above".
The sheet used to make the bottom, top and other parts is 2 mm thick, and the legs made from square tubing 5x5 cm.
The car brake disc you have seen is used to store heat and stiffen the top.
I made the door frames from a flat bar 50x4mm
Remember not to use the usual glass, because it breaks under the influence of high temperatures!
