Hi Jeff, Thanks for the great videos of your stove conversion.
It was useful to see the fuel wood in the "magazine" being burned from the cut ends. So often a woodstove burns logs that are essentially horizontal, and it makes a difference if you present the bark-side or the split side down to the bed of embers. The grain structure being more open and exposed on the split face encourages a more rapid burn. This is my main unknown as yet, how would a split log combust and pyrolise, if presented to the ember bed, cut end first. I suspect that there would be little penetration of heat axially, directly through the end, because the ring structure presents a tough barrier. Therefore, most burning would have to come radially, and so air nozzles would have to be positioned to act radially on the sides of the log. In your design, it looks similar to a Rocket, but with the fuel container near vertical. However, the top loading hatch looks fairly airtight? - so unlike a rocket, there is no air drawn through fuel. Nevertheless it appears to burn well and produces a healthy amount of good sized charcoal. I would be very interested to know how it copes with a larger log. Perhaps by way of experiment, one could be loaded, instead of the 2" material, to see how it fairs - this would be very useful information.
