Rocket stove made out of wood?

Made this yesterday, great fun, once its wide enough ill try and line it with empty cans and an insulator, looking for a simple way of coring out the center and feed? an ideas

That's a really cute stove, simple and effective. It would not be useable as a permanent rocket stove/heater, though - even lined with refractory clay or insulating brick, it would get hot enough to keep combusting the wood shell eventually.

This is exactly the concept I described in the thread about removing tree stumps by turning them into rocket stove cookers. Two plunge cuts with a chainsaw, and you're ready to go.

Iorweth Caradog : I have a favorite Winter camping site, an island that is not much bigger than a pick-up bed, an old unoccupied
Beaver house formally used as a firewood source and a wind break and with a large hollow cored hardwood tree open at the bottom and
banked with clay, I actually have sent it afire several times but with unlimited water from the beaver flow, I can put out any fire, the old
trunk weathers and drains so nicely I am hoping my grandchildren will enjoy it for a few more decades.

Or at least until all the closest of the Dead Standing Timber in this flooded hanging valley are used up ! Just off shore of my little island in
about 4' of water the sandy clay bottom has provided all the material for a fall re-line of the base of my 15' tall natural chimney! A small
tarp invisible from the islands waterline keeps dry the original Beaver den floor, an excellent sleeping platform rebuilt with deep mounds
of Cat tails! I should add that it is the hollow tree's immovability that promotes the longevity of this snug winter camping spot !

For the Good of the Craft ! BIG AL !
