[Stoves] sawdust stove

[Tony Vovers]

Kevin

We don't seem to have any additional documentation but I might be able to
locate the guy that built them. If I find something I will forward it to
you.
Apart from the inner lining of fire bricks the rest was just regular bricks
and cob with some metal grill parts on top as in the photos.

They are durable, the "heavy maintenance" was operational the cleaning up
and reloading time between operations in a busy kitchen and the mess.
A few bambu sticks were used from time to time if the sawdust was too damp
and during starting in the "rocket" hole otherwise it was only the sawdust.
