Sorry for those who don't speak French, these videos are shot in my native language. The most surprising thing about this experience is the excellent resistance of the internal metal chimney, made with an oxygen cylinder, 1cm thick. At this rate it would have lasted for decades, unlike anything I've ever seen. This metal "is NOT doomed"!!!!! Pour les francophones: depuis quelques temps j'ai commencé une série de vidéos autour de nos poêles préférés. Je débute totalement et la qualité est encore médiocre mais le contenu pourra en intéresser certains. J'ai démonté récemment un vieux foyer Rocket qui a servi 4 ans, et ces vidéos sont un retour d'expérience, un peu de présentation, quelques conseils et réflexions. J'espère que ça vous plaira . Voici la dernière, les autres sont en playlist. Le truc le plus surprenant de cette expérience est l'excellente tenue de la cheminée interne, faite avec une bouteille d'oxygène, 1cm d'épaisseur. A ce rythme elle aurait résisté des dizaines d'année contrairement à tout ce que j'ai pu voir. Ce métal "is NOT doomed"!!!A l'inverse, le bidon lui s'est percé...

Are you burning with the riser insulated? If not, the intended temperatures will not be reached and the metal may be able to have an extended life by not oxidizing as quickly. Risers are generally well insulated to reach extremely high temperatures and cleaner burns

Man points at metal tube. Man points at bricks. ... Very french.

Yes the chimney was well insulated with at least 5cm vermiculite contained around by a metal layer. You can see this piece by the end of the video. I think this stove was not one of the more efficient, because of the long bench, but he worked well and four years long. The barrel, he, is destroyed, so I think there's something else. Maybe the chimney's metal was a kind of most resistant, I don't know anybody else using this kind of Oxygene bottle for this purpose, no more than metal pipe 1cm thick.
I feel like a bit of sarcasme... Either I understand English too poorly and that has nothing to do with it, or you don't understand French and as we say in our country "quand le sage pointe la lune, l'idiot regarde le doigt"...
Anyway, I don't pretend to make good videos. Feedback is very rare, while there are lots of freshly made stove videos. Well, if it's bad, I would at least have tried to share what I learned when others only show their successes.

Well hey good deal, if you have easy access to cheap or free bottles like that is great!

Aww c'mon, it's been 18 hours : surely long enough for a taunting riposte?

I can only speak for myself, but this is something I would only use if I had a ready supply of oxygen tanks, and even then I would only use it in an emergency.
Risers lined with ceramic fiber do a much better job at producing the higher temps than a couple inches of vermiculite, and thin stove pipe as the outer shell will last forever.
If i didn't have ceramic fiber (and I didn't for several years) I found that a perlite/clay mix totally outperformed the very first riser I had which was a double walled stainless steel insulated stove pipe. So while it did work, I didn't get my outer barrel glowing cherry red until I started to use the clay perlite riser.
I go by the axiom it is better to keep metal out of the burn chamber and riser

At the time I built this stove, more than four years earlier, I've just only seen this way of doing it, not knowing the batch-box concept, because I have only taken my information in french language. It was the first rocket stove I ever seen, and build. Since then, I've made perlite riser, and I would certainly try ceramic fiber in the futur. This piece of metal was the best I find, thanks to a friend, as it was well know that it don't last very long with the usual steel pipe. I'm surprised that it resist as well
