DIY: How to make a backpacking wood gasifier stove

[RumbleTouchDroid]

fail way to make a hole bro, this isn't fucking rocket science.

[BCoutdoorsurvival]

@RumbleTouchDroid Thanks for the feedback. Do what you can with the resources you have. If you want to show me a better way, I'd love to reference your video.

leatherman...nice touch, some guys use a tape measure, but well hey the hand tool leatherman puts a nice touch on things

[BCoutdoorsurvival]

@mike184ever1 Multi-tool multi- purpose. Cuts down on weight and makes things easier to manage.

[vulcanfeline]

my dad used a tin can stove in ww2. it's only 1 can with large hole punched around the top. i can see where this would be more efficient, but in a pitch, a single can stove would do nicely.

a big ALSO: make sure the can you're using isn't lined with plastic!!

[BCoutdoorsurvival]

@vulcanfeline Definitely! And good point about the plastic.

[rakehell404]

You can simplify the assembly by putting the large can upside down, using the small can to mark a circle, and then cutting out the circle. Then, all you have to do is drill both cans and gently tap the small can into the hole you made in the large can. A few more suggestions... you don't need the holes on the sides at the bottom of the small can. The only holes you need on the small can are the ones near the top. The large can only needs 4 half-inch diameter holes.

[BCoutdoorsurvival]

@rakehell404 Thanks for the feedback I'd love to see a video of how those changes work. If you take a look at the video I link to of the improvements you'll see that I too got rid of the side holes at the bottom and kept the holes in the actual bottom. I've tried various combinations and found for my altitude what I did to be the best combination. I'd love to see your results though!

[creektimothy]

great video!, one thing, those aren't tin snips they are used to cut clothes off people by doctors.

just saying

[BCoutdoorsurvival]

@creektimothy Hi Timothy and thanks for the comment. Ha! They do look like those scissors though that emergency teams use! The "tin snips" came in a cheap tool set that I got several years ago. It certainly wasn't a medical kit though. They are much cheaper than normal tin snips, but that's what they were called in the kit. Regardless though, a real set of snips would do the job better.

[arthuracosta]

thanks buddy. try experimenting with turbine powered, hehehe i think it will be more fun.

[fireplug1701d]

I made one very close to this after watching your vid, only thing is I dont know what to do about a fitting to put the cooking vessel on but it burns good and hot.

[BCoutdoorsurvival]

@fireplug1701d Glad to hear it burns well for you. You can make a stand out of a smaller diameter can with holes in it or even hardware cloth. If you get a good design I'd love to see it!

[reaznb]

Thanks for the Video! I built one just like it and am planning on using it over the next week on my camping trip.

[BCoutdoorsurvival]

@reaznb Awesome! Tell me how it works! If you want to send me photos I'll post them on my blog! Don't forget to try the clean burn attachment!

[reaznb]

@BCoutdoorsurvival Clean burn attachment? Whats that?

[BCoutdoorsurvival]

@reaznb watch?v=cZ6zVKBnjOs

[reaznb]

Well I did not have much luck with mine, looks nice but did not produce a lot of flame and just made a lot of coal. Oh well might keep my hands warm on a cold night or carry as a fire starter. Was fun to make. Thanks!

[SuperDeltaRomeo]

Nicely explained,good vid.All the steps were clear.Thank you

[BCoutdoorsurvival]

@SuperDeltaRomeo Thanks for the feedback!

[mrfirelover212]

Great video, I tried doing this but I had some trouble removing the rim of the top can. Could you tell me how you did that? When I tried with my can opener the can just bent. Please help me!!!!

I need this for a presentation!! Thanks

[BCoutdoorsurvival]

@mrfirelover212 Hi there! The biggest factor is your can opener. Can openers are designed to open in different ways. Some work better on the top, others on the side. If your can opener doesn't do the job, try using a hack saw on the rim (or borrow a couple from friends)!

[AdrianTregoning]

Nice one, thanks! I'm going to try this..

[BCoutdoorsurvival]

@AdrianTregoning please do! tell me how it goes!

[feeshmaninpisa]

go to 7:25 and tell me if im just delusional.

[BCoutdoorsurvival]

@feeshmaninpisa to what are you referring. Either way I'm pretty sure you're not delusional :)

[dramey03]

nice design i was wondering how good it would work till the end

well done, ill be stealing your design ;) thanks

[BCoutdoorsurvival]

@dramey03 Feel free to use it. There's another video with a clean burner attachment too. I'd love to see any improvements you make on it.

[turkeyguy0]

is this an actual 'wood gasifier'? i thought a wood gasifier was wood being broken down with water and heat to produce wood gas.

[BCoutdoorsurvival]

@turkeyguy0 not all gasification is done with water, although that style is used in some configurations. Water is used to "scrub" the gas to remove tar.

There is some controversy on the subject. This style is called "inverted downdraft" and quite possibly does not meet all the standards for wood gas applications. Try googling it and as well looking for the phrase "wood gas". The term wood gas and gasifier are used for similar portable stoves.

This was just a complicated way of saying "maybe".

[outdoorsman310]

i used a coffee can and pushed a soup can into it

[BCoutdoorsurvival]

@outdoorsman310 how did it work for you? have you seen my video on the clean burn attachment?

[outdoorsman310]

@BCoutdoorsurvival it works well i might make a video on it il check that out. what does it do?

[BCoutdoorsurvival]

@outdoorsman310 clean burn attachment makes less soot on the pot.

[jw934]

I think with some simple modifications this stove (or any TLUD ND stove) can be made to burn with blue flame and without leaving sticky tar or powdery smoke on the bottom of the pot. To compensate for the lower heat output, a pot skirt will be needed. Pot skirt is different from a wind screen in that the pot skirt should be 10mm from the pot and rising up to at least half the height of the pot.

[BCoutdoorsurvival]

@jw934 It's definitely worth a shot. I'd love to see your results, especially on how you'd mount it to not interrupt airflow. The more people working on this, the better they'll turn out!

If you check out my related video you'll see a clean burn attachment that cuts down on the soot. Your idea might work better though!

[emjackdad]

Could you, at the quite likely sacrifice of your peaches or whatever, just cut the hole for the inner can into the larger can top without actually removing it from the rest of the can? Seems it would be one less loose thing to keep up with and the seal would be tight. Just a thought. I have not tried this, but hope to in the next few days. Thanks for a great video!

[BCoutdoorsurvival]

@emjackdad i only see that being a problem if you drill or saw (leaving shavings in the peaches). if you can make a rough hole first you could get the peaches out and then perfect the hole. I can't wait to see your results.

[RJBURG]

oops pop rivet can to the cover then cut both

[RJBURG]

why not pop rivet both cans together then cut out the middle out

[BCoutdoorsurvival]

@RJBURG I'm not sure I understand. Are you talking about riveting the bottoms together? The walls are meant to have a space between them. Maybe a bit more detail? I'm sure it should make sense, it's just really late!

[JesterBushcraft]

Brilliant tutorial, thank you !

[BCoutdoorsurvival]

@JesterBushcraft Thanks for the feedback. IF there's anything else you'd like to see, let me know!

@Rock9409 I haven't studied japanese in several years. I hope you can show this to your children. It is a neat teaching tool for "clean" energy.

[Jacobsantillan01]

u can use one can

[BCoutdoorsurvival]

@Jacobsantillan01 HI there. I have tried the 1 can method and I found this one more effective. Are you talking about Mark Jurey's 1 can high efficiency gasifier?

[jjb3point14159265358]

Dear Mr. Adventure, For a long time now I have been watching your videos and admiring your skills, always learning something. You are probably one the best survival channels and your fire skills rock! Thnx 4 ur tutorials and diy stuff, very helpful for my camping trips.

[BCoutdoorsurvival]

@jjb3point14159265358 Hi here JJB 3.14..., Thanks for the complement. I'm learning too and its a lot of fun. PLease let me know if there's somethin you'd like to see here or on the blog!

All the best,

- Mr. Adventure

[NocturnalBreather]

are these things better or worse than rocket stoves? and do they make char coal?

thank you

[BCoutdoorsurvival]

@NocturnalBreather Thanks for the questions! The Rocket stoves create heat by adding a lot of air to the bottom of the stove. You'll see that they end up with sooty pots. The concept here is that they limit airflow to the bottom of the stove and add it at the top. The result is a more efficient burn that requires a lot less wood. The result is a small quantity of charcoal because you've limited air access to the wood itself. If you check. Better efficiency and cleaner. Not necessarily faster.

[NocturnalBreather]

@BCoutdoorsurvival thank you very much. :)

[yashinoa09]

bobo ang liliit ng butas na ginawa mo hindi yan gagana ng maayus kung ako sayo lalakihan ko yung butas sa labas na lata kasing laki o mas malaki pa sa butas na ginawa mo sa burner!

[BCoutdoorsurvival]

@yashinoa09 Hindi sa tingin ko sa iyo na maunawaan ang konsepto. Gusto mong magdagdag ng hangin sa itaas upang dagdagan ang kahusayan. Mangyaring aaral kahoy gasification.

[TheWilderwolf]

i packed it way better this time and it worked 100% better. as it was burning, i could see what you were talking about with the gas coming back up at the bottom. some other stoves i've seen use just a grate at the bottom. or maybe its that the bottom is too close to the air vents and the gas is being blown back? thanks again and good luck with refining it. please post if you solve it

[BCoutdoorsurvival]

@TheWilderwolf I've been experimenting with separated air flow for the bottom and jets. I'll probably do some testing tomorrow.

[BCoutdoorsurvival]

@TheWilderwolf another thing, did you use 3inch and 4 inch cans? if the space between the walls is too small it also restricts flow.

[BCoutdoorsurvival]

@TheWilderwolf I'll be posting a video in the next day or two about some changes and heat deflector. The result is a much cleaner burn that doesn't leave nearly so much stuff on the bottom of your pot.

[TheWilderwolf]

thanks for the great vid. very informative. i made one like yours the other day and it worked fine, but the "jets" didnt seem to work too well. they only worked some of the time and when they did it was only about half. any idea whats wrong?

[BCoutdoorsurvival]

@TheWilderwolf  What can happen is that the air flow all goes in the bottom of the can. You can try 3 things. Was your wood packed in there pretty well? IF you pack a lot of wood in tightly then that should restrict how much air can come in the bottom. Alternatively you can add larger holes on the outer can to allow more air in, or have less holes on the base of the inner can. I had someone recommend that I get rid of the side row of holes on the inner holes. I am still refining it.

[TheWilderwolf]

@BCoutdoorsurvival ok thanks ill have to try that. it didnt work at all when i first built it, but after making the outer holes larger it does work just only has the jets sometimes. guess ill test it out and see what happens.
