Batch cookstove with a small riser

[Deleted]

Hi everyone,

Thank you all very much for the suggestions ! The plancha and all the metal work are done now. I will fetch them tomorrow !
Now the whole masonry work is done. The metal plate I use to weld on is use as the plancha.. the weather became very cold and we had to heat ourselves !
Some pictures meanwhile :

I love thats!!
Congratulations.
Works well?

[satamax]

Yep, love it too.

Yasintoda, were did you say you are? I saw the Revel adress on your site.

Myself, i'm not too far, serre chevalier.

those steel "L" profiles are 2mm? They won't bend?

When you look closely, you'll see they are welded together in order to obtain more stability. As such, it's a lighter gauge large T-profile.

Hi Everyone,

The heater is done !

Max, I was in Revel nearly three years ago. Now I'm on the south west of France. That's why you see this "briques foraines" in the bench. Some of them are said to be from the 13th century !

The metal profiles that hold the top of the bench are T profiles 50x50x5 mm. Two of them.

The bench is a little bit too hot on the top. On the sides there is 130 mm and on the top 100 mm. This was a mistake ! More mass on the top, less on the sides for the next iteration !

The channels are not working as good as I hoped for. There is a clear hot spot on the top right over the end of the middle wall. I think the gases are short circuiting too much the rest of the bench.

The refractory clay mortar couldn't cope with the dilatations.. I had to rebuild half of the two last rows. Once the tweakings are done I'll use an hydraulic and ceramic setting mortar. There is a clear linear push from the bricks on the left corner. They push the lintel above the oven door. It's very clear and it breaks the mortar.

Metal work was tough but I find the end result really beautiful.

Some pictures below, more to come later :

I personally tried that if you use the brick on the narrow side, especially in the core or adjacent to it, you have to use ceramic socket mortar.
I also thought I would use in a large bells a ceramic paper insert as a bedding set.
For the rest it is aesthetically fantastic

Yasintoda, in the Lot?

I lived there, near bretenoux and vayrac.

[satamax]

I would love to transform a cantou into a bell.

looks great! You can always add more bricks on top of the bench if it is too hot.

Metalwork is great, I guess large metal surface heats the space similar to barrel.

It's a common problem on single skin stoves. I doubt it's the bricks pushing up, more likely the door frame, but can also be the cooktop pulling up as it twists from thermal expansion. Dose the top have expansion plates you can lift out?

Nice build. Well done

Max, in the Tarn-et-garonne !

Vortex, it happened before I added the metal parts so that's why I know it's from the bricks. There is no direct contact between the bricks and the metal frame. I use a system I copied from the russians : uzume-asso.org/assets/docs/metallerie/plans_batchrocket165_foyer.pdf

And yes there is a disk to allow the dilatation.

I uploaded a small video to show you the cookstove more clearly :

How does it cook? What's the boil time on water? Does the whole top get to cooking temp? I assume the door above the firebox is a small oven?

Looking good

[reyh]

Great, it's very nice, especially metal work! And it seems to be working well. Have you ever had big flare-ups?

Hi Joseph,

I've been doing temperature measurements today !

The temperatures on the plancha are at their max. 40 minutes after the beginning of the fire. The max temp. is 320°C on the plancha. From 10 min to 1h50 after the beginning the temp. is above 160°C.

So it's approximately two hours of "normal" cooking time and then approx. 3h of slow cooking with temp. above 100°C.

Regards,
