Well, with just wood i can manage somehow. There's just two things how to implement the geometry of the rocket and be able to use long pieces of metal and also keep the metal in the bed of embers. This is a big point, if there's air and flames, metal doesn't heat enough. And also how to make the rocket hotter. I'll pursue my quest towards the cyclonic rocket. I'm pretty sure this can work.
One question thoughtIs the rocket getting hotter as a rocket cooking stove? Or as a RMH with the barrel? I have two six inchers, one of each type, and i've tried only with the heating one so far. Modified the cooking one into a J tube yesterday, and will make a small oppening for front air today.
