THE INVERTED IDEA
Since the above video i decided to flip the can so I can feed the can from the top instead.
The inverted can idea works much better, produces much more heat having the larger hole at the top
allowing the smaller hole at the bottom to produce more draft. actually a faster draft.
Thinking.. the good thing about the top being able to open I can load it up to the top with pine-cones and pine needles and get a quick heat happening or fill it full of wood at the start then light it.
The fire can now be fed from the smoke hole at the top back, the lower front smaller hole or by lifting the lid to put a large amount of wood. This works much more efficiently.
