Tetkoba-san! I tried your method and it worked close to what you demonstrated. I made a few mistakes, but overall the stove worked. For your experience, I boiled water outdoors in 42 degree F weather. It took 500ml of water about 8 minutes to boil. Thank you again for your wonderful instruction.
As always, incredible workmanship. It is truly amazing what you are able to do with simple tools. Your "adding fuel" test makes me think this stove design could be used to make a remote canister stove.
We are project, working in ethanol as household fuel. It's a great pleasure to follow up and learn from what you're doing. Few researchs are doing in this field and no company is now able to respond to our request, Very embarrassing situation. Always a big thanks for sharing
i made the rift stove -worked great; much better than my penny stoves. i really want to try this new capillary hoop stove. please let us know when the more fuel efficient stove has been designed! Appreciatively, a big fan of your creativity
that´s the reason of driving a japanes car. they are almost perect. love to see how you assemble the parts. very good video. You get my like and you earned it. Thumbs up for Nippon.
Hola, yo admiro tu pasion por las cosas bien hechas, y no solo lo funcional, sino tambien lo estetico, gracias por compartir tu arte y tu creatividad, de verdad se agradece, Manuel de Venezuela...
wow, I've just finished mine! I sanded 0.5mm off the top piece to fit better with the middle piece, I also used red gasket sealant too. Unfortunately, the middle piece had 2 big creases when I inserted it into the bottom piece which bubbled while it burned fuel, next time I need to make all my creases a bit deeper so it fits in to the bottom piece better. Thanks a lot for your excellent design ideas and experimentation.
Thanks for the extra details! I have been making the grooves with needle nose pliers and twisting... not as neat as using a ruler, but much faster to do. For strip skirt I am testing using hole puncher, again faster to do.
I like the simplicity of CHS but I noticed it's a fuel hog compared to the hoop stove. I'm also working on a CHS that is fully adjustable, I will post the video when its done.
Very nice, I would you to ask you the Vargo 'Copper Pipe' for adding alcohol when using, I have Vargo Alcohol Bottle, how to make the Copper pipe, thanks a lot.
hello Tetkoba, I have a question. At 2:14 you say scratch but do not detach yet. What tool do you use to make the scratch around the can? Thank you for the great design!
How do you get your jets to angle? I am having trouble getting them to spiral. When I drill them out (even when done at an angle) they still burn straight up. Also, how do you know where in the right to place the burn holes. Through my trial and error, it seems that it matters. Thanks, great videos!
Do you drill the bolt holes in the inner crease can piece before or after installing it when wanting to add bolts? As in, put it all together, then drill or pre-drill the holes in the outer can and inner crease can? Love the videos, very creative!
It's all about the fuel. Isopropyl alcohol burns with yellow/orange flames and soot. Ethanol burns mostly clear with orange tips (no soot). Methanol burns with faint bluish flame (no soot), impossible to see in daylight.
@@xenaguy01 I've tried 75% ethanol and it burns mostly red/orange with no soot, and 95% denatured ethanol with soot. I have not been able to create the blue flame he showed in the video so I wondered.
hi tetkoba. I just watched your videos and going to try make one(maybe I'll start with CHS) but I want to ask you because I still dont know much about the mechanism of alcohol stoves what type is used by trangia stove? open jet?
I forgot to ask, could you please give the diameter of the can you start with? I believe the cans I have a slightly different in size, and I need to know by how much to adjust your measurements. Again, thanks!
Tetkoba-san, this video and the original video do not show how you measured and drilled the jet holes for a CHS-U type stove. I see one for the eCHS, but that is drilling through a can top. Is there a video for drill the jet holes in the bottom of a can for a CHS-U?
Do you design/fabricate anything else aside from stoves? (I bet you'd be great pioneering diy engines; mayhaps, to cushion the departure, pulse-jet innovations?)
Jack Reacher once the skirt is creased it seems like it reduces the dia. just enough and slides in quite easily for me. i used just regular soda cans to make mine, worked just fine.
Jack Reacher The burner part with the jets, though the same diameter as well and not creased, will go in with a little pressure. Aluminum will stretch a little, but don't use too much force or it can tear or deform leaving a noticable bulge in the outer part.
i've tried this layout on 6,5 cm can, with the same creases and jet hole, but the combustion is not stable. can you tell, how much creases and jet holes should i make? thx, sorry too many question.
I'm not sure its detailed phenomenon and reason. Also I've not found optimized number of creases/jet hole yet. By my two/three trial models, 10 jets is good for 65mm diameter cans. Although I have no answer for number of creases, I think 20-24 creases is better. And smaller hoop capacity is one of important points. Hope this helps.
Sorry I don't sell. But my friend will start eBay shop and then you can buy. I'll make review video of him stove and other stuff in this month. Stay tuned!
Great, thanks for the prompt response! I will probably post another question if it arises, i find the two separate videos for the build a bit confusing, but I should be fine. I think I don't understand the jet port drill part. Should the ports be drilled at an angle? Or straight in? Will a thumb tack be ok for the width?
I'm making detailed how to make video but maybe end of this month. In this video two V8 juice cans are used. I always drill by 0.5mm dia. at first(straight). And drill by 0.7 or 0.8mm dia. with angle.
Jerkabobber Yes, I'm pretty sure every part is made of a bottom of a Red Bull can, and we need 3 parts. Can't wait for the V8 CHS version ... V8 juice is the stuff I can actually drink ) Red Bull just goes to waste

You have my respect and admiration for the quality of work you do and the dedication that you give.
Greetings from COLOMBIA
really cool demonstration of the physics, the capillary action is so cool, useful in so many ways
The moment at 1:45 when you picked up the stove with your bare hands made my eyes bulge in surprise. That is just incredible.
We are project, working in ethanol as household fuel. It's a great pleasure to follow up and learn from what you're doing. Few researchs are doing in this field and no company is now able to respond to our request, Very embarrassing situation. Always a big thanks for sharing
Wow! You are a true artisan. Thanks for so openly sharing your wonderful designs! As always, they are inspirational.

Happy new year! Thank you for sharing your knowledge to the world!
Beautiful video!
A true mater piece.
This looks like a great stove, easy on the exterior but sophisticated on the inside!
BoilOn!
I love your work, its so inspiring. You have made this into Science meets Art.
that´s the reason of driving a japanes car. they are almost perect. love to see how you assemble the parts. very good video. You get my like and you earned it. Thumbs up for Nippon.
I love watching your videos. Makes me want to try new concepts.
Thanks for the reply. I still love this stove. Thanks for sharing your wonderful designs!

of all can stove video ive ever seen this tetkobas alcohol stove can performed very will.. thank you my friend..

+causaljoe note to self (and all) Don't use red gasket sealant!
causaljoe True, red gasket sealer can be a mess. If you need to seal the burner to the capilary liner, JB Weld, high temp epoxy, best stuff there is.
Thanks for the extra details! I have been making the grooves with needle nose pliers and twisting... not as neat as using a ruler, but much faster to do. For strip skirt I am testing using hole puncher, again faster to do.
Very nice, I would like to ask you the Vargo alcohol fuel bottle 'Straw' for adding alcohol when using, which is DIY or where to buy, thanks
I like the simplicity of CHS but I noticed it's a fuel hog compared to the hoop stove. I'm also working on a CHS that is fully adjustable, I will post the video when its done.
I have about 22 creases. I tested it with little fuel, enough to boil 1 cup of water. I held it about 2 minute after it started burning.
เยียม ๆ มาก ๆ. ความคิดดีน่าสอนเด็น ๆ มาก ครับ
What is the concentration of alcohol used? Thank you
Very nice, I would you to ask you the Vargo 'Copper Pipe' for adding alcohol when using, I have Vargo Alcohol Bottle, how to make the Copper pipe, thanks a lot.

Watch FAQ video 2:09 pls.
FAQ to my tools

you deserve a nobel
Do you drill the bolt holes in the inner crease can piece before or after installing it when wanting to add bolts? As in, put it all together, then drill or pre-drill the holes in the outer can and inner crease can? Love the videos, very creative!
Drill small hole(0.5mm) on inner piece before assemble. Drill larger 3mm hole after assemble.
what makes some of the stoves burns blue flame and some red/orange? and does it leave any soot on the bottom of your cup/ pot afterwards?
It's all about the fuel. Isopropyl alcohol burns with yellow/orange flames and soot. Ethanol burns mostly clear with orange tips (no soot). Methanol burns with faint bluish flame (no soot), impossible to see in daylight.

What tune is playing please?
Awesome Vid and love that backing track! ;)
Arigato Gozimasu!
hi tetkoba.
I just watched your videos and going to try make one(maybe I'll start with CHS)
but I want to ask you because I still dont know much about the mechanism of alcohol stoves
what type is used by trangia stove? open jet?
What tool did you cut the bottom of the can out with? (The pre-cut footage looks as if your fingernail cuts a perfect disc out it!)
なるほど！ありがとうございます。
I forgot to ask, could you please give the diameter of the can you start with? I believe the cans I have a slightly different in size, and I need to know by how much to adjust your measurements. Again, thanks!
Awesome! Thanks a lot.
which is more fuel efficient the capillary hoop stove or the regular hoop stove with carbon felt wick?
I try to make creases. But I don't prosper. Can you recommend a other idea?, Can I use drill 1mm?
main issue to me still is the crease. even with a triangle scale i have problems doing it. do not seem profund enough. another way to do it? thanks
I use a small triangular file/rasp.
Good stove! I luv it Senpai
Tetkoba-san, this video and the original video do not show how you measured and drilled the jet holes for a CHS-U type stove. I see one for the eCHS, but that is drilling through a can top. Is there a video for drill the jet holes in the bottom of a can for a CHS-U?
Steven Varner Almost same work. I'd like to suggest use JB-weld to inner and top and drill after adhere.
Thank you. I will do that.
My CHU stove's temperature is very hot. How were you able to make yours burn cool?
Very cool brother :o)
Do you design/fabricate anything else aside from stoves? (I bet you'd be great pioneering diy engines; mayhaps, to cushion the departure, pulse-jet innovations?)
Very nice
Is this your best stove to date?
How do you make the hole (that of 38mm) in the top piece ?
I use circle cutter. You can watch my FAQ video. FAQ to my tools
Thanks a lot :-)
Is it danger refilling the fuel directly? @@
anyone know where I can buy the metal pipe, fuel line and fuel line cap in the USA?
ありがとうございます！もう一つ質問があるのですが、アルミ缶をきれいに寸法通りにカットする方法は他の動画にあるように、ブレードを木のブロック等の上部に固定してカットするのですか？例えばアウターの高さ45mmの場合は45mmの高さのブロックに刃を固定する。このCHSの場合は３つのパーツ、8mm 32mm 45mm とありますが、これように３つブロックを作る必要があるということですよね？
「つまり、このようにブロックを 3 つ作らなければならないということですか?」
いいえ。本を用意して、適切な高さになる 2 ページの間に刃を置きます。8mm の場合は約 50 ～ 60 ページ、32mm の場合は約 200 ～ 250 ページ、45mm の場合は約 280 ～ 300 ページになります。
底の部分はヤスリのみを使用するだけでカットできるのですか？
Why 30cc? What does happend if put more alcohol?
Amazing talent/skills! People like you make the rest of us look so dumb! Are you planning on mass marketing/selling your inventions?
AMAZING :D I'm building one of these :P
I want to buy, how much to send to UK. I pay paypal right now
I think thats the most efficient alcohol stove so far.
can i use alcohol?
I wish I could buy these from you! You need to sell them :D
Cool.
Very nice. I couldn't do better myself. Which is why I will be blatantly copying all of your designs in an effort to flatter you :)
It looks like all 3 cans are red bull. If so, how do you fit the "skirt" part inside the bottom part of the stove, since they're both the same size?
Jack Reacher once the skirt is creased it seems like it reduces the dia. just enough and slides in quite easily for me. i used just regular soda cans to make mine, worked just fine.
wentz3306 I thought that might be the case, but wasn't sure. Thanks!
Jack Reacher The burner part with the jets, though the same diameter as well and not creased, will go in with a little pressure. Aluminum will stretch a little, but don't use too much force or it can tear or deform leaving a noticable bulge in the outer part.
hey, can this lay out applied to reguler can?
Yes if you can.
i've tried this layout on 6,5 cm can, with the same creases and jet hole, but the combustion is not stable. can you tell, how much creases and jet holes should i make? thx, sorry too many question.

Although I have no answer for number of creases, I think 20-24 creases is better. And smaller hoop capacity is one of important points. Hope this helps.
one last question, if i made CHS-U but i make a little taller, is the combustion change?
No, you can get same combustion.
Do you sale stoves?
Sorry I don't sell. But my friend will start eBay shop and then you can buy. I'll make review video of him stove and other stuff in this month. Stay tuned!
somebody please... sell this stove to me... :(
lol how much
USD 5 😊
If I could buy one of these for an affordable price... XD
No, as you watch.
I guess this must be some kind of engineering project. I can't see much practical use for this. Looks like something Macgyver could have come up with.
It's ideal for ultralight backpacking.
Fuck, I'm jealous!; Why doesn't MY mind produce anything beyond how to eat and shit? No fair; YOUR mind functions! (I'm sure that's cheating!).
Ok I'm committed to make this one.
I got my sanded down red bull can ready to go.
My initial question (before I get started) is, do I need 2 cans?
Yes. 1st can for bottom(outer) and inner. 2nd can for top piece. Happy DIY!
Great, thanks for the prompt response!
I will probably post another question if it arises, i find the two separate videos for the build a bit confusing, but I should be fine.
I think I don't understand the jet port drill part. Should the ports be drilled at an angle? Or straight in? Will a thumb tack be ok for the width?
Rewatching the original build video, I find I need 3 cans total... I never realized its built of 3 bottoms
I'm making detailed how to make video but maybe end of this month. In this video two V8 juice cans are used.
I always drill by 0.5mm dia. at first(straight). And drill by 0.7 or 0.8mm dia. with angle.
Jerkabobber Yes, I'm pretty sure every part is made of a bottom of a Red Bull can, and we need 3 parts. Can't wait for the V8 CHS version ... V8 juice is the stuff I can actually drink ) Red Bull just goes to waste
