OK, it appears appropriate that having graduated to Shed 2, I should advance to Stove 2 in a similar vein.
This is for my allotment brew-up. My existing paint can rocket stove is this
Whilst it was functional, it lacked the rocket-y element, most likely an insufficiency of air. That could be seen in the not that impressive heating and comparative difficulty lighting.
For Stove 2, I have scored a bit of 100mm square section steel tube (for the purpose, lets ignore that it's 5mm and consider that an aid to longevity. When future archeologists unearth the evidence of the culinary habits of the agrarian members of the second elizabethan age, they won't have to wonder, as it will still exist)
My current thinking to create a simple L shape with a mitre, then a platform a third of the way up for the air/fuel. The platform would end before the combustion chamber.
Options are, a J shape (why?) another feed pipe for the fuel... any thoughts?
