Homemade double jet alcohol stove

[worldwideweppon]

Or use a kettle !

[albion2742]

Did you mean less THAN 1/2 (not less THEN )

[lebammabel]

@albion2742 Yes - THAN, sorry.

[bpolitepass2urright]

how long did it burn with that much alcohol in it?

[lebammabel]

@bpolitepass2urright I haven't measured burning time with this particular burner. I didn't use much this two coil burner which of course is quite powerful but not economical. Instead I use single coil burners which are enough powerful with longer burning time. Only measurements i have made with my mini glass burner which with 60 ml of alcohol burns around 30 minutes.

[joel750]

Very cool stove BUT very impractical for backpacking use.One could use this for emergencies like power outages, bivouacs, car camping & that's pretty much it. Besides, if one is not careful these very stoves would just suddenly blow up in your face! This is the very reason i personally like the Open Top stoves like Trangias & the White box Stoves.These stoves has the potential to be a ticking time Bomb waiting to go off given the chance & take the user along with it. :(

[lebammabel]

@joel750 This stove was not build for backpacking. I am not hiking and therefore don't need something very small. However I made one small burner but just because I like to make something my selves. To tell truth I haven't used this particular double coil burner, don't need too much power. Instead I use single coil burner. Only worries with glass burner that you can break it, but it is not going to explode.

[lebammabel]

@joel750 Those burners with glass jar was only like training for me, I have made already copper stove. There is nothing to be afraid of, pressure of vapor is too small to blow it off stove of course if you don't close jet and keep above fire. And this stove for me is more practical than your Trangia.

[JMEBF]

Looks great buddy,.. but isn't a bit dangerouse? I'll try making may own... Cheers

[lebammabel]

@JMEBFFire is always a bit dangerous and has to be used carefully and better to use outside. Sometimes even commercially made stoves explode. I my selves haven't had so far any problems with all my homemade stoves. From my experience can say that single coil burner is more than enough.

When you make your stove take in account weather conditions (temperatures). It is important to check if your stove doesn't overheat in hot weather. If yes you have to make some adjustments to prevent overheating

[lebammabel]

@JMEBF by adjusting size of nozzle (if not adjustable), by adjusting space between coils. Ones I experienced some overheating for my copper stove in hot weather, but it was not dangerous. Fuel consumption was too big because of too big flame.

[theredlines2000]

I have to say this is absolutely awesome..... Finally someone makes a killer camping burner for a wok. You rock bro!

[lebammabel]

@theredlines2000 I am glad if you like it.

[Mrgunman1955]

why is it so loud?

[lebammabel]

@Mrgunman1955. Most of open jet stoves are quite loud and here are two jets with good vapor pressure. If you noticed when I covered jets with kind of jet screen or flame deflector it got less loud.

[XxmindcellxX]

I dont care how much it weighs, it looks so fucking cool and works so well why not carry it?

[irishsky005]

And this affair weighs how much?

About 10 lbs.?!?!?

Nice stove, if your having to cook for the entire Allied Expeditionary Force.

A better plan might be to make a pop can stove.

[lebammabel]

@irishsky005. It weigh 800 grams (1.7 pounds). Stove body (tinplate construction) weight is 400 grams (0.88 lb) and this particular burner's weight is also 400 grams (0.88 lb). I agree this double coil burner isn't economical. I made it just to see how it works with two coils. If you don't need to cook for the entire Allied Expeditionary Force, I can propose some smaller burners. You can find them in my you tube account.

[lebammabel]

@irishsky005. What about pop can stoves - I have them and I use them only when there is no other options available. For me this more like interest of making. To make can burners all the time got little boring.

[cslr11]

great stove how long will it burn for .

[lebammabel]

@cslr11. I haven't calculated burning time for this particular stove, main task was to get it working. I assume this "double jet" burner isn't very economical. The only time I calculated burning time was in video "Homemade coil pipe alcohol stove - mini (frying potatoes)". This burner burns around 30 min. with 60 ml of alcohol. Some impression about burning time you can get from video "Frying eggs and bacon with coil pipe stove".

[cslr11]

@lebammabel Thanks for the info I will check out the outher vid's you talked about. I am going to try to build one.

Thank's againg keep up the great vids

[bluemountaindrivepae]

Looks heavy. How much does it weigh? There are third world countries that use wood and coal to cook and heat. Wood and coal are unhealthy to burn indoors. Deforestation is causing erosion and dust storms. Great invention keep on posting.

[lebammabel]

@bluemountaindrivepae. In my opinion stove isn't very heavy, but I am not hiker and I didn't care much about weight. Most important was to get it working. It weigh 800 grams (1.7 pounds). Stove body (tinplate construction) weight is 400 grams (0.88 lb) and this particular burner's weight is also 400 grams (0.88 lb).

Later I thought maybe I can make something smaller and I did. If you are interested you can find videos in my account.

[festilina]

Awesome.

[Skilled08]

sweet



[teb0atoz]

Do you need to use the alcohol container made of glass, as this is the only container I have seen. Not sure if this is because glass is the only type of container there is with a metal screw on top or if there is another reason.

Cheers

[lebammabel]

@teb0atoz

I think it is possible to use fuel container from any material as far as it is heat resistant. Glass jar for me was easiest possible way to make burner. However I have also made copper burner. It works wonderful. You can check video in my account or look for video "Homemade copper alcohol burner".

[utubeworms]

Not really suitable for back packing though cool design none the less.

[lebammabel]

@utubeworms You are right this stove i didn't make for back packing, although it isn't bigger than some commercially made. I used it when traveled by car and used single coil burner.

[boomer00000]

doesnt make it sound any less like its going to explode

[boomer00000]

it kinda sounds like its about to explode....

[lebammabel]

@boomer00000

But it isn't.

[TheionDesigns]

Oops. Totally re-read that comment and see how that sounds like I meant to be superior to you. My apologies. That was not my intent. I just like making things more and more simple. Like you I started making stoves and just kept improving them. I actually have stoves in my car as well. For me, ease of use means that I actually use it. Also, I mean that it is fun to take others ideas and go from there rather than reinventing the wheel each time. Keep at it!

[lebammabel]

Sorry if I misunderstood. I don't really mind you to be superior. The only thing is that every body has different interest. What is interesting for me, probably not for others and in reverse. I also like to watch different videos, most of them are very interesting, full of good ideas.

[TheionDesigns]

Please check out the Theion Designs video response. Light and easy, this stove simmers for an hour with 2 oz. of the juice. The stand weighs less than an ounce. It's fun to make stuff, but it's more fun to make stuff better.

[lebammabel]

I am happy if you like you burner. I can't say that I like it very much, however I have something similar my selves, just as backup burner. And I don't think that your stove is better. Simpler yes, but not better for me. Every body makes something for his own needs. I didn't make my stove for hiking and therefore I don't really care very much about size. But you are right, It is fun to make stuff better. After this stove I have made three other stoves.

[Bassman018]

Jeez, I might as well carry a MSR Whisperlight with all that crap to haul around!

[lebammabel]

I am happy about you.

[BrokenAeroVT]

He didn't make it for backpacking. He takes them travelling with him in his car he said. Does GE and HotPoint make backpacking stoves? Look how big those are. ; ) but at least they have 4 burners and an oven, lol.

[lebammabel]

If you know the joy of making then you should understand why people are making something.

And those Coleman stoves are very expensive, quite big and still very heavy. You can say that my stove is also big (but not heavy). Yes but I have made already much smaller one. With 2 oz of alcohol it burns 30min. And I don't need to carry big Coleman stove to warm up meal and alcohol gives more than enough BTUs to make meal. Actually I can also use Coleman fuel after small adjustments.

[deroldzzzzz]

nice, but can it fly? ;D

[lebammabel]

Just make wings.

[fletcher0102]

how do you shut it down?

[lebammabel]

This burner can be easily shut down by blowing off flame (in video I tried to demonstrate that) therefore it needs in windy weather kind of windscreen. But with windcreen it is quite windproof.

[lebammabel]

Burner can be shut down also by closing jet hole with peace of metal or screwdriver.

[montanaangel64]

Nice and steady! make me one!

[hogshead50]

Very nice,what does it weigh? Four pounds?

[lebammabel]

Stove weight is much less because of tinplate used. It weigh 800 grams (1.7 pounds). Stove body (tinplate construction) weight is 400 grams (0.88 lb) and this particular burner's weight is also 400 grams (0.88 lb).

[hogshead50]

Thanks for the info.

[SthealthRaider]

Looks damn explosive ....

[lebammabel]

It is not so explosive as it looks. Glass it quite durable to heat and looks like it doesn't reach so high temperature like metal. And it is possible to adjust flame by changing wick and jet size. Only problem is if you drop it - it can easily brake. But I don't make glass ones any more, it was like step to metal ones.

[SthealthRaider]

Ok so il make the coke can jet stove ;D But i still have no idea on how to bend the tube without sand

[lebammabel]

You can try to heat tube. After heating it becomes quite soft. Another way is to fill it with water and freeze and then right away bend. But in my opinion sand is best and it is everywhere.

[countrykid902]

fill it full of water, plug one end and set it up right with it full of water and freeze it

[kc7fys]

A good one for car camping, where space or weight is not an issue.

[mabaidada]

what do you think about my stove (from mabaidada). is the design correct. in this video i have not put the wick. sorry, because i dont now the best wick can be used. thank you

mabaidada

[midgetsarescary]

first ive noticed in all these vids if you guys would just raise the pot a little you should get a faster boil time second what grade of alcohol are you using

[lebammabel]

You are completely right, raising pot can decrease boiling time. In one in my videos i am trying to find needed hight. This hight seems to be optimal(very approximate measurement on eye).

This alcohol I bought in Tourist store, it is made in Germany, called - favorit Spiritus, Ethanol ca.94%.

[Massastriker]

i noticed u didn't use alcohol in the primer pan, what did u use?

[lebammabel]

That was alcohol, but you can use anything which doesn't make smoke.

[Alberich666]

Hmm... The jar thing alone would make an excellent Bunsen burner.

Impressing.

[4Mengineering]

great sheet metal work there!!!!!!!!!!

[filandron]

Pretty cool for homemade.

[RJBURG]

What size are the tubes.

[lebammabel]

This burner is made of 8 mm copper tubes, but for burner in background and on other video (single jet burner) i used 10 mm copper tube. Yes there are wicks in tubes. I tried to insert them as far as possible (I thing till point where tubes start to curve). First I stretched them to make thinner and stronger and then inserted with no big force.

[RJBURG]

Its a glass jar right and the tubes in tank got a wick in them and how hi into the tube do they go. nice job.

[lebammabel]

Yes it is glass jar.

[Maija27]

Awesome!!!

[xsplosive1975]

when you blow that out there is a very large amount of fuel lose but other then that much props on being a homemade stove very nice work now how about a dial to turn it down a bit ??? anything like that for the future??

[lebammabel]

I did not show it but it is possible to close jet hole with cork as it is on other video (Single jet stove). And loses of fuel are not so big you can not see them. As I know there is requirement to release pressure after burning in all stoves. For this stove there is no need to do that, I have tried to close jet immediately after burning and it was ok.

[lebammabel]

Actually I haven't invented this stove, I saw something similar on internet (Pitorch or Stesco stove)and tried to make it my self without welding.
