How necessary is ash removal and on how regular a basis?
This stove will borrow some design features from the bigger rocket stoves except I will rely on the extended flue for the heat. But it is for the winter camp so I can't pick it up and shake it outside and the fuel loader will only be 135mm in diameter so a bit tight for my hand
I am using an old stainless steel pressure tank with a small hole in it to take a hose attachment
I'm after a 20 litre drum with a removable lid if anybody has one for sale, this is for the container to hold the firebox insulation
