“Ok, the Rocket Stove heated, Cob Sauna is on!! There is a client who will pay me to build one, which is GREAT! ‘Cause it means I’ll actually have the time to build it, and see it finished in a timely manner.
I’ve delivered the urbanite for the foundation today, I’ll be prepping the parts and picking out the brick and whatnot tomorrow. Hopefully by Friday, I’ll have the rocket stove guts layed out and working. Most of the guts of the stove are going to be below floor level, so I gotta build the stove and the foundation together.
Ok. Today I built the platform that the stove will sit on and insulated underneath with pumice. I chose pumice ’cause I’ve had it laying around for some time and it was a freebie, also I expect that it will encounter moisture occasionally. Seems to me that pumice will handle a periodic wetting better than perlite or something like that. Today I also built and tested a quick-and-dirty 6 inch rocket stove on the platform. It felt right, to gauge system size by just making one and staring at it. It seemed to me, (after fiddling with wet wood in a wet 6″ stove on a gusty day) that an eight inch system will likely be more appropriate.. So tomorrow, I tear it all off and build an eight inch system in it’s place.”
