Skiddable structures are great, you can drag 'em just about anywhere. Now you got it there, you need to level it. Rocks to the rescue! Build a level "foundation" under your skiddable structure, to both level it and slow rotting of the skids.

Cob is a very useful material. You can build a house with it but you can ALSO use it as an all around patch and filler material.

To get certified for this BB, do and post the following pics:  

- Use cob as filler between logs in a WOFATI
- Must be a minimum of 20 linear feet of filler
- Action pics
- Show yourself mixing
- Show yourself filling

I don't have any good images (or at least haven't found any) of making adobes in my stuff.

There are a few videos,

I think this one is one of the better ones:


This guy is always excellent. I think he makes it hard on himself with an overly dry mix. (and yes, he's making a kiln to fire stuff, the process is pretty much the same)

Might there be two or three decent youtube videos that you like that we could embed in this BB?



Dunno.  I'll search around.
I might have images too.

Adobe bricks are very useful objects. Adobes are essentially cob building blocks, where a large portion of the drying time (which can be significant) is done, before the building process is begun. They can be used to build a large list of items very quickly, including RMH, built in furniture, ovens and even whole houses.

To make adobe bricks you need an adobe form. Typically made of wood; they are a frame, open at the top and bottom for forming cob into adobes. A good size is 12 inches by 6 inches by 3 inches.
Find a flat piece of ground with no growing things on it large enough to hold a number of bricks. (in this case, 12) Rake the area of all organic matter, rocks branches etc.
Wet the adobe form by dipping it in water, place it on the ground and toss in a wet-ish cob mix (literally tossing in handfuls, throwing it down hard will eliminate air pockets). Level the mix off to the top of the form, then pull the form away, leaving the wet brick behind.
Wet the form between bricks
Repeat
When dry enough to move without deforming, flip brick on the narrow edge to finish drying through.

To get certified for this BB, do the following:  
- Make 12
- Show images of your mix and tools
- action shot
- Show image of drying bricks, on edge

Clay paints are a simple, inexpensive, effective and beautiful way to finish, color and freshen homes or just about any built environment.



To get certified for this BB, post the following pics:  

- Raw materials. Your clay rich subsoil, your flour and the tools you used
- Paint a minimum area of 4 feet by 8 feet

RMH Master Class

With Kirk Mobert, Ianto Evans (the inventor of RMH) and special guest, TBA.
LOCATION: The Cob Cottage Company, Coquille Oregon, USA
April 8th - April 30th, 2019
$ 3,000.00
We're only taking 5 participants! This is going to be intense, don't miss it!

The accommodations are rustic, at Cob Cottage, Co. in a small cob village (in stages of build) in the Oregon forest, in winter. It'll be wet and cold, but there should be lots of fire along with the mud, 3 meals daily, and dry camping indoors.

This 3 week course is an in depth look at Rocket Stove technologies. From simple cookers, through to Mass Heaters; Ltype, Jtype and BatchBox rocket feeds, we will discuss them all. We will cover materials usage, including home-made high temperature mixes, created from scratch. We will build 2 full working systems, as well as inspect and repair some existing stoves in order to learn how to spot common problems and fix them.

This course features:
~ Build a wood fired hot water system. This system is unique in that total safety is built directly into the basic design. Heating water with wood fire is normally very tricky and done wrong can be very dangerous, leading to steam explosion, maiming and death. We will build a double boiler system, which can never explode.

~ Build a scientifically advanced, but materially neolithic Rocket Stove Cooker. Rocket Cook Stoves are an important tool towards independent, sustainable living and can be incorporated into regenerative systems designs. We will explore how a sophisticated and very modern stove can be made from home-made, neolithic materials. Using these basic methods, a beautiful and useful stove can be built, almost anywhere, with almost nothing.

~Inspect and repair broken or unsatisfactory stoves. One of the best ways to get your brain around how Rocket Mass Heaters work, is to break a few and then fix them again.. These are already broken, we'll find out why and repair them.

Interested?
Call Cob Cottage Co. to register between 10:00 and 2:00 PST, Monday, Wednesday and Friday

The heater core (including riser) and floor are not counted in bell calcs. Internal pillars and whatnot are.

Thanks Erica, that's awesome!
