Since you are living that far north, is there a reason why you choose a partly single skin bell instead of a completely double skinned heater?[/quote]
My choyce is based on my ignorance. 1. Never build an oven. Briks or other material. Allways bought from stores wood burning stoves made from metal. 2. Have no connection with construction area. Metal/ piping/ welding is my home area. 3. For a guy who «welds» everything he builds , clay/sand/ wood ash it seems to me a weak connection 4. This way that I layed the bricks( on flat side ) the bell wil be only 114 mm thick , 2 meters high & 1,2 meters wide on the back of the bell. Not much trust in such a conception. But I understand that will hold in time. 5. The briks i have are handmade and not verry sqare. Inequal as thikness & wide .Bought here locally from a guy who keeped them over 40 years indoors. Verry nice old patina/ form and I am thinking only to oil them with linseed oil. No plastering for an older look. 6. I emigrated from southern Europe 12 years ago & not used yet with the cold. Brrrrrr....... thats why is so big core in a relatively small bell. Thinking :if the flue gases are hot the chimney will be hot on second floor too. 2 rabbits with 1 shot. Another thougt: what ifI build the topp of bell single skin with chamote briks? Single skin for coooold winters. Wil it be feasable?
Ps. Never thougt on dobbelskin all the bell only the top. The portuguese team is building too single skin up to riser level. Just looked at theirs pictures.

One more question Peter How and who make the molds for your nice brown heater. ?? Ispossible to buy them? Or to buy the plans. That way I don’t have problems with briks Much cleaner building process.

«It's best to place the outer skin first, alined with the front you've already done. Then, place a wide strip of superwool all around inside, the height of say, two bricks on its side. Then place two rows of the inner skin out of firebrick on its side using refractory mortar, usually the same as the core has been done with. And then, repeat this process .....» Peter you say to build first the outerskin. By the placement of the stove I did build first the inner skin. Enough place for outerskin too no problem. Verry keen to test fire before the outerskin is build .... it will be safe? Does anyone fired with only innerskin build?? More patience??

One more question Peter How and who make the molds for your nice brown heater. ?? Ispossible to buy them? Or to buy the plans. That way I don’t have problems with briks Much cleaner building process. Brown? I might be colourblind but I always thought it was red. The moulds were made by a guy in he Netherlands, polyurethane rubber in a plywood support crate. Sadly this person passed away last April. You can't buy the plans either, simply because the drawings are open source. Here's a link to the article, scroll down to the end of it. batchrocket.eu/applicatie#redrocketAnd yes, it was a much cleaner building process, in our house anyway.

Verry keen to test fire before the outerskin is build .... it will be safe? Does anyone fired with only innerskin build?? More patience?? I was talking about a bell in single skin below and double skin above riser height. The way I described it makes it possible to use split firebrick on its side for the liner/innerskin. I get the impression you built an inner skin from floor to top first. In my opinion, it seems feasible to fire it without the outer skin, just to dry it out and test fire it. You'd best to build the outer skin before winter sets in, the inner skin will expand much more and will develop cracks, no doubt about. The outer skin will protect you from leaks, no problem.

I have the feeling that we are lost in replyes Peter. The bell I build is single skin untill to rows under riser levell with red regular briks on flat side(114 mm). Over that level I did layed chamote briks on narrow side(64mm). Superwool and red briks on narrow side follows. All in all the bell is about 114 mm single skin thick under riser and about 145 mm dobbel layer over the riser. And you have not sight problems... is only my bad english . Sorry for confusion. My dutch is even worst. Saddly that company do not have a english menu. I cannot find it. I was thinking about shop drawings for moulds, the kind that shows wich are the sizes in millimeters of the moulds, how are they build and so on. Not the Scketchup models. I cannot slice the models on my iPad for some reazon. Scketchup I only use fot this forum/subject. Orher drawings I thake them in Autocad for students. Thanks for patience Peter

How the moulds are made I can't help you with. I know how it's done in general but it's complicated and there's a steep learning curve. Building moulds and casting an entire heater is much more costly as compared to building one out of bricks when it's just a single heater. Things are different when it's done as a series, making a vast number of parts in order to build multiple heaters.
