Hi,

I need a way to hook the 6-inch black single wall stove pipe to a homemade steel wood stove.
I tried the 6-inch steel pipe, but the pieces I had measured between 6.125 and 6.250 inches inside diameter - too loose.
How can I tighten it up? Or is there something better to use?

Thanks.

Allen Lumley : Is this close to what you have in mind?

An alternate version.
A barrel stove kit could be used with this one.

This is a sketch for a two barrel side by side stove. Would this work? I am guessing this would have to operate roaring-hot in order for the secondary burn to take place. If I could ever get it hot enough.
The wood is loaded directly into the first barrel. The bottom of the barrel can be lined with firebrick.
I don't know if this would be considered a rocket stove or not.

Maybe something like this then?

Someone more knowledgable can chime in, but can you try extending the 6-inch tubing down the barrel to within 4-6 inches of the barrel bottom? This way the hot gases will be forced to rise to the top of the barrel and then cool and go down and enter the exhaust/chimney. I don't know if this will actually work and provide enough draft but it could.

Jeff Rychwa, how is the tubing arranged inside the barrel? Is it one continuous "U"-tube? If so, how do you plan to clean out the ash? Shop vac?

It turns out there was a post with an almost identical topic recently: Mass Heaters without the mass?

So I guess this is not such a good idea. But I wonder why that would be? I guess this horizontal pipe gets hotter than I assumed?

Not easily, but it may be an option.

I have seen these "solar sheds" on the web that use a similar approach for storing heat outdoors. It should work with the rocket mass heater, I think.

Santamax, what stores the heat inside the bell? Air has virtually no thermal mass. It looks like the material the bell is made of is what captures and stores the heat, so if the bell is light weight, there is not much thermal storage. I can see a bell being useful as a heat-shedding or heat-coupling device though.
My problem is weak floors so I do not want to bring in much heavy masonry. Unfortunately I do not have a masonry wall to connect this to.
Do you have a picture of this fuel tank you have in mind?
Thanks.
