I've built several of your CHS designs for camping and I really like them! Although I want to say please don't handle JB Weld with your bare hands. It is common for people to develop an allergic reaction to raw epoxy over time through repeated exposure.
really like the design and ideas, thanks to you last week i try to make it "eCHS" using your video as guidance with limited tools that i have, and turns out come up really good, also i have cook some eggs and noodles with it several times. once again Thank you
Hello, I really appreciate your videos! May I ask you two questions? Why the need for JB Weld inside, at beginning of the video? And why there's a different crease marked with a screwdriver? Just to indicate the maximum level of fuel?
Sensei need some help .I followed all the steps according to your guide. The problem is ,my stove cant produce a complete flame combustion ,which is a blue flame. Got 8 jets with 1mm hole. And 17 creases inside. Just wondering why my stove creates a mix color of flame. Partially blue and yellow on top
There are two reasons. 1. I think your jets are too large. Amount of vaporization is too much, causing oxygen deficiency. Try 0.7mm X 8 jets or 1mm X 6 jets. 2. It also depends on the composition of the alcohol fuel. When ethanol component increases, it tends to be a yellow flame. My fuel is methanol 95% and ethanol 5%. Hope this helps.
Ok sensei ill update you soon. I'll post a vid for my 3rd stove. As expected to your advice my 2nd stove got improved. From rubbing alcohol to denatured alcohol and it goes so well and burns so smoothly ,unlike before .as of now im trying to build my 3rd alcohol and ill follow your advice. Arigato so much for sharing this beautiful masterterpiece of yours....
Hello, I am looking to build a small beer/pop can alcohol stove. My desired goal is for efficiency and long burn time rather than ultimate burn temperature. Could you recommend a design style best suited to these ends? I am also curious about a few things. First does building a stove with thicker aluminum walls help in any way so far as the basic performance goes or does it just make the stove stronger and heavier? Second, is a double wall stove inherently more or less efficient than a capillary stove? Last, can a double wall stove be built with a top like that used in a penny stove or must the top be wide open and if so why? Thanks for posting your amazing videos they are very entertaining to watch and your craftsmanship is astounding. Thank you for your assistance.
@@tetkoba: this looks excellent, how far above the flame do you need to place the pot? Can this model be mare to simmer or is it easier to make a high efficiency smaller simmer stove? Thanks so much for your response it is very much appreciated.
@@morayjames92 Well, I think less than 1 inch. If you need more simmer there are two methods. 1.simmer heat fire(under the pipe). 2. reduce jet hole diameter or number of jet on pipe.
can you make a self-pressurising stove that throws out a loud jet like flame? something like this maybe /watch?v=ClNE06KAEy8&t=61s but prettier and simple as possible?
hat type of stove has a fatal problem. With commercially available adhesives, including JB-Weld, it is not possible to achieve both strength and heat resistance. BLAST BURNER from FREELIGHT is product of this type, but it is solved with a special ordered adhesive. ua-cam.com/video/TmZ0D_BGHQU/v-deo.html
Tetkoba, at 9:36 you show two stoves - one with a blue flame and one with an orange flame. Is the flame blue because the JB Weld is giving a better seal?
Well, I think fuel difference. The right side straight flame eCHS uses alcohol fuel with a lot of ethanol component(almost 30%). The left eCHS uses 5% ethanol.
Thank you very much, Tetkoba. Here in New Zealand, our fuel (called 'methylated spirits') has a lot of ethanol in it. I've been wondering why I always get an orange flame. Does the straight flame eCHS have good efficiency? Sorry to ask so many questions!
Maybe when the flame goes straight up, it reaches the bottom of the pot more quickly and doesn't have time to mix with oxygen. Thank you once again, Tetkoba-sensei.
正に工業芸術品!!アカデミックで孤高な感じもしますがここまで丁寧に説明なさるのはさすがです。

Thank you! Very nice videos and your craftsmanship is impeccable.
Would love to be able to read all your notes/comments in english.

美しいデザイン
First and amazing videos been watching since 3 years ago
Hello, I really appreciate your videos! May I ask you two questions? Why the need for JB Weld inside, at beginning of the video? And why there's a different crease marked with a screwdriver? Just to indicate the maximum level of fuel?
I was wondering about that too.
There is a slight gap between flange and body. The JBweld as gap sealer.
The mark is, yes, indicator of the maximum fuel level.
Thanks in advance! I'll build another CHS like this! The previous I build is working really fine for 2 years
コメント失礼いたします。つい先日のことになりますが、動画を参考にしながら試作させていただきました。動作はしたのですがジェットがほぼ上向きになってしまいました。真っ直ぐ貫いたあとで少しずつ45度くらいに、と動画の通りやってはみたのですが…斜めに噴出しトルネードになるには何かコツがありますでしょうか。
うーん、自分なりに数をこなしていろいろ試して自分なりの方法を見つけてもらうしか無いんですけどね。私はこれまで数千個を作ってきたんで、そうそう簡単に真似されたらそれはそれで悔しかったりしますが（笑）
@@tetkoba す、数千……これは失礼いたしました。精進いたします！
Blue flame is makes me feel satisfied. :D

What are the questions at the end?

さすがに見た目はとても綺麗ですね。私もかっこいいの作りたいですね。^^
What a master piece!
Of course the one with the chemical seal burns better, judging from the color of the flame.
Смотрю в ноябре 2022 года. Лучший и креативный вариант. Спасибо!👍
I can understand the addiction! Your work is beautiful, and approaches thermodynamic art!
見た目も炎の形もきれい！なので作ってみたのですが、本燃焼に移行できません。本体を傾けてジェット穴にアルコールを流してから火を点けるとしばらく燃えるのですが、その穴にある分のアルコールが燃え尽きると真ん中だけ燃えている状態になってしまいます。なにか改善すべき箇所、本燃焼に影響が出やすい箇所などありますか？ご教示お願い致します。
内壁と外壁の接触具合が、この動画の6:00からみたいに、互いに軽く接触する感じになっていますか？

美しすぎます！さすが本家本元さんのCHSは違いますね。私もtetkobaさんの動画で勉強させて頂いてハンドクラフトのアルコールストーブにはまりました。これからも素晴らしいストーブの動画をお願いします。
コメントをありがとうございます。ちょっとの違いが炎の違いにつながるところが面白いですね。
Great, really. Thanks for yet another awesome tutorial!
いつも動画楽しみにしております。作り方まで丁寧に教えて下さるtetkoba様の動画には、とてもお世話になっており、また感謝致しております。
一点質問がございます。
私は約3年前、tetkoba様の動画を参考にCHS型のストーブをスチール缶で製作し、それは2カ月間の自転車旅行に耐えうる素晴らしいものでした。(現在もまだまだ使えます！)
しかし、加工が非常に大変だったことを思い出すと新しいものをつくる気が萎えます。
そこでアルミでも製作したいと思っているのですが、アルミで作ったアルコールストーブの耐久性はいかがでしょうか。
例えば使用頻度が週1の場合、どれぐらいの期間の使用に耐え得るでしょうか。
また、JBWELD方式と折り曲げ方式では、どちらが耐久性が高いでしょうか。
それでは宜しくお願い致します。
こんにちは
スチール缶の加工って大変ですよね。サビも気になるし。
アルミ缶の耐久性ですが、踏んづけたりする強度はもちろん低いですよ。その分スチール版の半分以下の軽量性がありますね。
JBweld版しか長期利用していませんが、数百回使って無問題。潰さない限り使えると思いますよ。
折り返し版は長期使用していません。これの懸念点は、落としたりした時に折り返し部分が凹むなどすると、そのままガス漏れにつながること。まあ少々ガス漏れしても湯は沸かせますけど。使用と運搬にあたって、より気を使う必要がある方法になるでしょうね。
eCHSよりCHS-Uの方が耐久の観点と炎のまとめやすさで言えば良いと思います。
ご返信ありがとうございます。
とても参考になりました。
アルミ缶でも数百回使って問題なしということで安心致しました。
また、改めてCHS-Uの動画をいくつか見直しましたが、耐久性の観点からはこちらが優れているということがよくわかりました。
これまで１缶で簡単につくれるという理由でeCHSばかりに注目し、また作ってきましたが、今後はCHS-Uの製作に挑戦してみようと思います。
そしてフィールドでバシバシ使っていけたらと思います。
これからもtetkoba様の動画楽しみにしております。ありがとうございました。
Do you sell any of your stoves
can you make a self-pressurising stove that throws out a loud jet like flame?
something like this maybe /watch?v=ClNE06KAEy8&t=61s
but prettier and simple as possible?

oh, tyvm for explanation.
anyone have any suggestions for two american canned drinks that will fit together well like this?
lol nevermind im an idiot
Tetkoba, at 9:36 you show two stoves - one with a blue flame and one with an orange flame. Is the flame blue because the JB Weld is giving a better seal?

I think straight flame type has tends to be lack of oxygen.
Maybe when the flame goes straight up, it reaches the bottom of the pot more quickly and doesn't have time to mix with oxygen. Thank you once again, Tetkoba-sensei.
Which diameter of drill is better?
I think Tetkoba mostly uses 0.7mm and 0.8mm drill bits.
Personally, I sometimes drill 11 x 0.6mm holes.
Amazing
Sweet.!!
