Hey Guest, Early bird pricing on the Summer Moot (21st July - 2nd August) available until March 31st, we'd love you to come. PLEASE CLICK HERE to early bird price and get more information.
Did some gardening earlier today and wanted a cup of coffee. It started raining in the middle of the process, but we don't give up that easily, do we? It cleared up after a few minutes and the coffee was served with a spoonful of sunshine.
Looking good Vestlenning.
Is there a gap between the top of the stove and the kettle? I found that using my kettle directly on top of the hobo stove was relatively ineffective (although it could have been the rather wet wood). I did look to make a trivet to place on top of the stove but couldn't really come up with anything to my liking.
How do you find the Eagle Products kettle? I assume it's the smallest size available (0.9L?)? I have the 1.5L (or it is 1.4L) version still sitting unused in its box. Also, what's that stuff around the kettle spout?

No gap. I've been thinking about some kind of trivet too, but like you I haven't got the right idea yet.
It's a 0.7 litre. A mug each for me and the missus or several strong cups if we've got guests. Light but robust enough - I like it.
I put the coffee in when the water is cold; when the picture was taken it had just started to boil.
I'm thinking a stainless steel ruler like this. At £1.99 it's a bargain! Multi-use too.
Saw off two lengths, maybe 5 inches long and then cut the slits to allow it to fit on top of the stove as a cross. Won't even need to measure the lengths
To reduce weight, I may consider drilling some holes through it.

What's a single wall tlud? Can't imagine how you'd produce and burn woodgas in a single wall container, I'd be interested to learn.

top lit up draft.
You fill the canister up with wood, up to where the holes are just below the lid and build a small twig fire on top of that. It then burns down the center and out (like a Sweedish fire log) gasifing the unburnt wood as it goes ( the heat build up in the container gasifies the wood). The fire draws air up from the bottom holes of the canister and the draft pulls air in from the second set of holes (just below the lid) which mixes with the "gas". Its basically the same as a wood gas stove except from the mixing part. You need a windshield for it to be efficient. It burns very clean (purple and blue in the flame) and there's hardly any smoke once it gets going (clean pot)
Ill take some pics/make a video of it in action when I can.
Thanks for the reply - I know what tlud's are and use one very often. I've made a good number of stainless steel ones, but I can't get my head around how it can work in a single-wall construction.
Pics. or a video would be an eye-opener, thanks

Here you go Macaroon. Best pics/vid I can get with my phone camera and a borrowed tablet/memory card.
Used hardwood floor scraps (oak and parawood) as its the only hardwood I had that's dry (stored in shed) Smidgen of tar on pot, but its minimal. Get about a half hour burn once its going.
Pictures
Video (Very limited on what I can do/upload video wise.)
Smokey start up. Fire on top starting to burn down. Flame starting to turn a little purple when it hits the wood in the canister. Then just burning. Tried to also show how little/no smoke there is when its going

Both the video and the pictures are very clear, and I'm amazed by how efficient your stove obviously is; it looks a cracking compact bit of kit!
I spent an hour or so earlier on to see if I could find an explanation as to how this works and the principle behind it, but with no success; I'll have to search further and see if I can find an explanation of the science of the thing. I'm the sort of person who learns best from a written explanation of the principles involved with perhaps a diagram; there are loads for the twin-wall design but none that I can find for your design.
Thanks a lot for taking the time to do this, I love to learn new stuff and this has been an eye-opener for me Back to the searching, then!

Back to the searching, then!Small disclaimer and an apology.
I know I've referenced to "woodgas" and "gas" and people call the small double wall stoves (and in this case single wall) "wood gas stoves" they're not really imho. They don't hold enough fuel, not thermal efficient enough and not really able to get enough air into the mix (even the fan ones). They'd need to hold enough wood to heat the chamber up properly, gasify the remaining wood and be thermal efficient enough to reach/hold a hot enough temp. Again this is just my opinion from playing about with these type of stoves. Just like to think of them as efficient wood stoves (with minor gasification)
I will try and draw a diagram Macaroon (of the single wall) and explain it to the best of my knowledge (and from what I can work out.) Then Pm it to you/post it somewhere else when I get the time to do so.
I apologise Jack for the slight derailment and sneaky hijack of the "Day out Brew up thread "

That'd be great, when you get the time; you obviously know a fair bit more than I do about the science of it all, and I just love to be taught!
I too apologise for the derailment, but I've often found that sensible little off-shoots like this can be really instructive and interesting; serendipity is sometimes great......

I do love these little home made jobs.
My IKEA one is great, all that air around it makes for a super hot fire, small but really effective. I've just been in the garden with the kids. We have toasted marshmallows and boiled a kettle in a very short space of time. Kids love it !
