>>2813245OP here.
Just to end the thread before it dissapears, this is my idea of a hobo stove that I will try to make.
The ikea piece from the first image, with legs that i will just carry inside of it and screw them when I use them. And I'll use a canister as a rocket stove head with legs to support a pan and so the fire can exit better.
Thank to everyone who participated on this thread, especially
>>2813330 as thanks to him i searched for the supercat stove and found several youtube channels that helped me understand how to make a good twig stove for camping.
