6" batch box + benches done (but some minor touch-ups)

[manuel]

Hello all since a long time appart from stoves... (some guitars on the bench, lucky me)

Here we are with a new project, now on the design and trial run. It seems to work nice. We've proved our RMH get a much nicer function when placed on the real sites, since the workshop in wich we work doesn't have the negative pressure on the flues it uses to have a normal house. And the place is sooo cold it get the gases on the flues (as they're still uncovered) too much cold too soon on their passage to the roof.



This one is far easy than our last experiment with the oven over it so it went far better on building. And we are coming to improvements in our construction techniques with jigs and templates. Maybe some of them could be usefull to some of you who build the barrel base with steel instead of brick and/or adobe. I'll post them when we make the photo-process on the real place (in a few weeks, we hope).

Meanwhile, here you have some photos of the workshop moke up.

Have a nice day and, once more, thanks for your big help.

Now installed on his home and building the benches. Weekend job...

Hello all, good people at the forum.

Long time since I posted some news about this rocket. The "Ona" is done, just a few touch-ups left waiting for us to hace some time to travel to the place she's built (350km from home).
My cámera lenses were broken on the building process so I was not able to have good pics from then on... most of the final stage's ones were made with a cellular.

It's cold here now so I want talk to the customer to know how it works in his house.

Now I'm making plans for my next batch-box for a house we've rented. I'll let you know on a new thread.

Have a nice day and greetings from León, Spain

Beautiful.
Did you fabricate the barrel using mild steel plate?

Ahh. I just checked your gallery : all is explained. Nice welding.

Manuel ,beautifull work.

[manuel]

Thanks, drooster and independentenergy.

Yes, we found it's better in some cases to use welded iron plates to make te barrel. It helps with the manifold - flue junction, is goodlooking and and we don't need to burn and peel the reclaimed drums. On the other hand, it's heavy (that's the reason we put some temporary handles on the barrel and made the pillars for the assembly..) and we should spend some money on the plates and time on welding. We liked it a lot anyway and Fernando (my partener at bio-construction and the one welding at the photos) loves to work with metal too.

For my next one I think I'll go on with the reclaimed drums. And for the bell (in case nobody gives me some reason not to use folded iron to make the bell's core) I won't weld it but fix with rivets sealed with some sort of cement before covering with cob.

Nice clean build, and nice clean building techniques!

[manuel]

Thanks a lot, Satamax.

We had some fun figuring out different ways of making jigs and fixtures to make them. Now we feel comfortable about building bench-style RMHs.

Now I'm triying not to break my brain while trying to understand bells and ways to make them. Let's see how my nex project goes

Beautiful build. What type of temperature readings are you seeing from the end result?

Specifically: Flue terminus temps, exchanger temps and that cooking surface!
