A re-do of my 5 gallon stove idea. Using the RocketStove concept.
(you will see the changes briefly in the video below)
I put a hole in the center of the lid like a rocketstove and may later enlarge the hole to the size of my kettle, still thinking on that. A larger hole will increase the draft at the bottom but a hole that is too large may be a problem causing too much unwanted flame around the bottom of the pot making it hard to take a pot off without getting burned and cause the flames to go around the sides of the pot. Might as well just have an open firepit and hang the pot with a chain. Controlling the wood consumption in the stove is a far more efficient idea.
The tin you see is a very old tin. Probably was used for varnish or an oil of some sort back in the 1970's. I am not sure if you can buy a tin of that gauge any more. I managed to pick this one up from my dad, he had it kicking around in the yard. It is a very solid tin.
While experimenting with different ideas to keep the pot up high enough from the exhaust hole I finally settled with the backpacker\s grill that I had for kayaking trips. Using a backpacker's grill it can easily span the top of the tin can lid.
This is still a work in progress. Once I get what I want I will paint it with high temperature BBQ paint. The nice thing about using the 5 gallon pail rather than a 1 gallon pail is the burn time and while at camp I would like the longer burn time for cooking dinner and relaxing by the stove for warmth in the evenings.
