Batchbox and RMH projet

Hello Peter.
I have made the corrections and submit the model for your approval. In your last recommendations, you suggested that I lower a course of bricks from the bank and add a course of slabs. With this, the internal height stays at 32 cm and in another post you told me that the correct one is 35 cm, at least. Do I make that change?
Thanks, Peter.

Most of the time the question will influence the answer and I don't have the time nor the energy to read all the answers given before. So I'll refrase my recommendation for the specific situation.
In your drawing, height of the bench is 8 bricks, the opening to the exhaust is just three bricks high. So as compared to the normal recommendations, the exhaust opening should be around half the height of the bench' internals. Lowering down the seat one brick means the exhaust is still less than half the bench' internal height. There's a stream of gases entering inside the bench at the top, and one that's streaming the opposite direction over the floor. Those two streams aren't the same volume but also not at the same proportions during the burn. So that 50% proportion between entering and exhausting will be just a rough quess albeit an educated one.

Understood, Peter.
I have a tendency to go my own way, with age I have learned to listen to the voices of experience and knowledge. I will follow your instructions to the letter.
Thank you for your patience.

Hello Pedro.
I think the design is now ready for examination.


Regardless of whether it needs correction, I have a dilemma. The house where I will do the batchbox is 1000km from where I live, obviously I will have to use a vacation for work; but in the meantime I value doing a test of the core, here, abroad, not so much because I distrust the design but rather my constructive capabilities. I would do it with a slip for later disassembly and transportation to its final location. For one thing, I know the value of pre-testing, especially when it's your first time at something; but, on the other hand, dragging 300 kg that distance at the price of diesel is not going to be cheap. Writing this I realize that nobody can give me an accurate answer, however I would like to know if any of the novice builders would have liked to do a test before the debut
