Batch rocket instead of J : door on the side possible?

Hello,
slow, but the project is going on and at least the trench for the underground pipes are there.
I had time to see the birth of the batch rocket....
I have more or less understood the innovations, I got the measures...

I have someone (profesional) who can do it if I can get with enough guiding for him. He has already used cob and is ready to take some time for it, but not that much, and I cannot pay for more hours than do the job once!

So I must prepare as much as possible.
My first question is about the basic design: can I put the door on the side?
I have seen the form near the heat riser, the p-channel and I am a little afraid that the door HAS to be on the opposite side!

Then I am not fond of the kind of work to cut the barrel: is the old solution still posible?
I will not use a barrel but will buy a cilinder at the right size.

There have been discussions on Donkey's forum about various door/firebox/riser configurations. One I have followed recently has the riser on the side of the firebox, not the door (the logs still go straight in, not parallel to the door), but the overall depth would be significantly less than the standard setup. This one is for a short, "riserless" configuration, but I believe you could just as easily put a standard riser in place of the horizontal afterburner.

I'm not sure what you mean by "cutting the barrel" or "old solution" in this context. A batch box doesn't necessarily need the barrel cut any more than a J-tube does, depending on layout. And you can certainly use any steel vessel that has the right clearances instead of a barrel.

Thanks to both, I am going to read this.
I have already lerned that it smokes if you open the side door during the burn, which is not a big problem in a batch type, and in a not so cold place as mine!

Glenn, for the barrel, I mean that there is a new type of very precise cut, so that the flue can go out of the barrel.
The old way for me, was to build this ash tray below the barrel, so that it was not cut.
I prefer not to have to cut the barrel.

Satamax, there is a nice pic of a nice rocket from Hendrick, I just wonder where the heat riser is hiding!!
1st I have to read in debth, I copy and read at home out of connexion....

Nicola, check the pics!

Yes I had followed that link!
And should have edit.... well, the heat riser is very short, no?

Very nice building though complicated, specialist's work.... professional result.

His build is the first "per se" side door batch rocket. The heat riser is short. But still longer than Matthewxalker's riserless's builds. Myself, i would do a longer heat riser. But this was just to let you know it has been done before.

Great.
I have to do the most regular rocket possible.
With a tall heat riser.
I begin to suspect that a lot of people push the limits because they rely on the chimney!
The real chimney should be the heat riser (or I did not understand all very well....)

As I live below a 10 meters cliff, no way to get the chimney above the roof.
As cold air goes down at night from above, no way to risk reflux.
(yes, I get the smoke from my above neighbours...)
