It worked just fine! The beginning of the burn is shown, I burnt it for about 2 hours with sticks and dead fall from the woods. The wood was far from dry and not ideal in any way but the bit of smoke seen at around 1 minute in cleared up entirely when it began burning well. I started with a little pine straw (them are pine needles for all y'all who ain't from the south) and one blow on them when they started burning immediately started a good draw. During the entire two hour burn it never once smoked back. It was calm outside and this rudimentary build was just to test the hypothesis that the riser could slant up at an angle from the middle of the burn tunnel with no ill effect on the burn. I would say it worked just fine! Anyone care to comment?

Well, between you and Matthew, you reinvented the range.
Next step, fit a white oven in the bell you've drawn, and make it a smidge smaller(to account for the oven isa), and presto, you have a nice working range.

Funny, I was kind of thinking the same thing. I need a large hot area on top of the bell too but that should be workable don't you think?

Well, i told you before, a big 3/4 inch steel plate on the whole top of the bell, just resting on stove door joint should do the job  |

Right on Cramer! Glad to see you burning stuff, looks like it works just fine.

Very encouraging! Thank you very much Cramer (and Matthew) for sharing your less-than-vertical-riser results!!

Yeah, I will have to search and see where I might be able to find such a thing. Well, that is the cart, I should not put it in front of the horse. Lots of things to do before I get to that point in the project. It appears to be very encouraging, I don't know if you can imagine the amount of enjoyment I derived from this little test. I was all giddy when it started drawing right away and when it never smoked back even a bit ecstatic!  All the thanks goes to Mr. Walker and Peter van den Berg (oh I hope I spelled that right) for the guidance and everyone else for the encouragement! |

Cramer, may be easy or might not be. Secondhand restaurant supplies for example. Scrapyards, look for old ranges or something similar. I agree it's hard to find. I have a rusted one waiting for me in a bog where i had stuck my four wheeler on the bottom of a draglift once. I wonder if that metal plate is still there |

Nice Cramer. iam looking at the vid and i am not sure but seems i can see some smoke. I am wondering if the riser is not straight, than maybe there is no turbulance, and it cant burn all of the gasses... just a guess. What do you think about that?

Robert, maybe you didn't read the post and just looked at the video. The video shows only the beginning of the burn. The smoke cleared up a short time after the video was shot and I put my face in it several times and there was only the slightest hint of a smoke odor after it began burning well. You also don't see flame at the riser because it was at the very beginning of the burn but it was clearly visible a bit later in time as things began heating up.

Ok, sorry. I didn`t read all. Thats very nice than. Seems like you have broken a rule, and it is working  |

The rule is not broken at all Robert! It is just angled a little. The proportions are still correct, the riser is just not vertical. We might say a convention was broken but not a rule as such.

Cramer, i know where you can find a good metal plate for your build! Earth works. When they dig trenches, they use, at least in europe, a big metal plate, so a car can go over the trench, if it is to be open for a few days. There's been one on the bridge at the bottom of my village, for at least a year 1 inch thick 10'x5' or thereabouts! I'm prety sure you can find something like this where you live. And even, you might find it cheap, if the norms call for a change every five years or something. |

Oh yeah, until you said something about that I didn't even think of those! Now to find someone in the State or County for a hook up! Thanks man! Good idea!

Great to see the prototype worked - makes you wonder if a u-bend in the sloping heat riser will work too?
Is there is a local company that makes fire escapes etc? They may have some spare checker plate. Some types have a higher carbon content which makes it less prone to warping.
I've salvaged the hotplate and the fold-down covers from my in-laws old Rayburn (a solid fuel cooker popular in the UK). On the underside of the hotplate it has thick ribs at the end where the flue gasses are hottest. If you make a hotplate this may be a feature you want to copy, maybe with some angle iron. It will also help reduce warping.
