guns4toys Homemade Wood Gas Stove Configurations

[johnqsurvivor]

Excellent! The best on how to I've seen! Very informative and helpful. Thanks!

[hydraman5]

this video is perfect.it cannot be improved in any way.extremely well thought out.the best on YouTube in my opinion.

[MrWatlow]

@hydraman5 Ditto!!! This is the best video on home made wood gas stoves 'Ive seen on YouTube

.

[1LonePuma]

So how is the lip of the second inner can attached that the third can rests on?

[1LonePuma]

Ah, this is what I was referring to...forget precious comment, you answered my question.

Best regards

[diontoldme]

OK. Absolutely the BEST instruction video on these stoves that I have seen! THANK YOU SO MUCH!!

[FacetsOfTruth]

Extremely nice video, Brother. Well done! I've seen a lot of videos and you are definitely the best one so far. Thanks for your expert teaching style and knowledge. I've decided to make my first stove based on your model. God bless and happy camping to you.

[06butlertul]

i have made a wood gass stove bit i get a lit of soot and wet soot stuff and i was wondering if you now how to stop it. chers tully

[rogierius]

At 5.58 guns4toys explains how the lids are fasten to the inner can. It seems easy.

[WildmanBorneo]

Great Thanks

[redcolt777]

which is the most efficient stove that you have made?

[dchinell]

You did a great job preparing this video. It's jam-packed with the kind of useful information one needs -- but no fluff. You covered all the bases with a minimum of fuss. Thanks!

[Backpackerdad3]

just made one based off your design here.... worked pretty good. I think the one improvement I could make is in can sizing.... I think my inner can was too close to the bottom of the outer can... but oh well it worked pretty darn good anyways. Thanks!

[fiftycal211]

it all comes down to how clean you cut the hole. the way I did it was I used the reemer on a swiss army knife.check out a video" how to make a wood gas stove" by

86thmountmerrion

[strawalker]

Very well done, thanks.

[gladtidings4all]

I would like to buy one of these or all three of them since I'm not handy and don't have tools besides being a girl but I would love to go camping. please let me know thanks.

[hillbillyfarmer61]

Outstanding presentation! This is the best demonstration and explaination of a wood gas stove that I have seen on youtube. I hope you have more videos on other topics. I will look for them. Thanks for a great video.

[sailsinthesunset]

Thanks for the EXCELLENT video, as above I to have been looking for a decent video. Great workmanship. Again Thanks, great job.

[amorphuc]

Thanks for the video. Your attention to detail is astounding. Your drilling almost looks like they were percision punched or something.

I also like the way you mentioned Exactly what type of can with ounces and such. There's no room for second guessing after watching except for how you got the top hole cut out to accomidate the insert can so perfectly.

I'll read on in the comments for the answer.

[DrWeebot]

Pay credit where credit is due, mate, have built my own and am very impressed with its performance. All-round a pearler, will make the cold nights fishing smoke free and non-existent from now on. Hats off my friend.

[LAZERBEEMofTRUTH]

how did you fasten the cans to the lids? are they welded? or just smaller than the actual diameter and bent?

[guns4toys]

@LAZERBEEMofTRUTH Thanks for watching. The hole in the lid of the outer can is smaller in diameter than the inter can. Tabs cut around the edge of that hole bend down when you push the can through and spring load against the inter can holding it tightly in place.

[sanchodomingo999]

@guns4toys the lid has a nice ringed edge, how was this made?

[paulwastaken]

@sanchodomingo999 - yes i'm trying to figure this out too?? guns4toys can you shed some light on this? a few people have asked about this.

[bigboatbore]

Thankyou for the accurate consise video. I'll have a go for next summers camping with the kids.

[billydenero]

Great video.

Now I can see how to make a stove.

Simple when someone can explain things well.

[billydenero]

Great video.

I can really see how to make a stove now.

Very usfull

[cheekyfumes]

Great vid, thanks for sharing your knowledge. I'm going to make one.

[three6619]

This is the most informative video I have seen on this subject so far. Thanks for posting.

[AlanSThina]

Nice video. Very well executed and explained. Kudos to you mate.

[Jigaboo123456]

Very clear and detailed, thanks .I endured a crappy clip made by some bean-curd eating hippie that had no explanatory narrative, just some other hippie whining a dismal dirge about saving the environment.

This is the biz! Question-- is it necessary to drill the bottom with such accuracy? There are so many holes --would it still work if you just stabbed a knife in and twisted it to make one large hole? Would have liked the theory explained and a clip of them burning.

[kihlstr]

I really like your stowes!

I have builded some of cans and other material i found and i like what i see in your work, that you are wery exact in all details in your stoves. :-)

Good job mate!

Vinni:-)

[osm3u]

great video, thanks for posting.

[RonRay]

Thank you! Not only did you not 'hide' your dimensions, configurations and even tools (like a lot of other folks on YouTube), but you gave excellent instructions so others can make their own stoves. You spoke clearly and concise about all procedures involved. You placed the camera on a tripod, so we didn't suffer vertigo trying to see what you were showing us. (I know this is all obvious to you, I only mention it so maybe others will perhaps follow your example.)

Thanks again!

[TheBgcheez]

Do you currently sell these or are you planning on it in the future? I would love to buy a couple of these from you as long as they aren't like 30 bucks.

[parkyjjb]

@TheBgcheez haha,,these are tin cans with holes in and you want to buy one,,just make one,im sure it would be more satisfying and a lot cheaper

[TheBgcheez]

@parkyjjb - some of us have no time to make anything that's why I asked. I know they are tin cans but these are pretty well made stoves and for a couple bucks I would happily buy one or two.

[rklcardinal]

@TheBgcheez

Get off your butt and make one.

It is important to actually do and through this, learn.

You might make improvements that will surprise you. It'll also tune up your problem solving skills.

[azphek]

Thanks for all the details. It will help me out a lot when I start mine.

[WayneSadler]

Hi I am in the live in the UK, and I am not sure if your tops pop on as you seem to just press them in for a snug fit. Now the thought is that you have kept the outer skin solid bar the holes so the top retains it's strength then use another can of the same for a top that just rest there. Now the question is is this going to work due to gas leaking. Else is it better to cut out the bottom as rmoving the ash could be a issue other wise. Your thought's please. Many thanks Wayne

[changeindirection]

Hi, thanks so much for the great video! I have been trying to bend my mind around how a wood/gas stove works, and how to make decisions about hole size. Would you care to comment on internal gas flows? I assume that the can opening (exaust) would determine the collective size of the inflow of the outer can? What about the intake on the inner can and what about the jet openings? You are probably too busy to coach someone on the theory side. But thank you again.

[zasvedogovore]

a 4th solution is crucial, i`m working to find out what is the ideal distance from bottom to gas-inlet holes (inner can) so gas could easily ingnite.

Also, I don`t have big solutin for draft controling system on outer bottom holes. At this moment, when the flames fade, I simply pour some soil or sand around can to stop draft for 95%, and keep coal hot but last to finish my meal with one fill up. Maybe a sheet metal belt with exact holes like on basic can, then just turn

And finally, I hope to

[zasvedogovore]

@zasvedogovore ...make a pot stove. Good luck to all. This is so addictive.

[crazykidmeinc]

how do you make the lid of the inner can not slid all the way down?

please answer

[paulwastaken]

@crazykidmeinc, I think i figured this out. I'm think he is using a "safe rim can opener" it doesn't cut the can like a normal can opener, but kind of breaks it apart, leaving the lid and the can with a rim that is not sharp and they fit tightly together.. i just ordered one ;)

[penguinistas]

Very well done video, with good, concise, information (not just rambling on about this and that).

I appreciate you giving the can sizes, hole sizes, tools used, and fuel usage.

One of the best informative videos I've seen on youtube.

[codynynex]

wtf?

[MsSpy]

Did you use JB Weld to epoxy the inner can and collar together? Or is that welded?

[389Lee]

Excellent details. I really appreciate you taking the time to share your stoves and make this video.

[whyerp]

Do you have any videos that show us how to make one?

[walkertongdee]

thanks your stoves were the best, especially the one that you can add fuell. The best of an all day search. You rock...

[msamour]

Thanks for the video, I will definitely be experimenting with some of your designs this spring. I will let you know how I made out. Cheers! Mike.

[munchichi8]

What would create more draft? The space between the inner and outer can thin or more space?

[munchichi8]

I appreciate the sharing of your videos. I just don't have time to make one.

If anyone want to sell me a small one send me an email.

[tsturdyboy]

I don't understand how you make the collar for the inner can so that it sits on top of the outer can. Can you explain?

[paulwastaken]

@tsturdyboy - yes i'm trying to figure this out too?? guns4toys can you shed some light on this? a few people have asked about this.

[paulwastaken]

@tsturdyboy, , I think i figured this out. I'm think he is using a "safe rim can opener" it doesn't cut the can like a normal can opener, but kind of breaks it apart, leaving the lid and the can with a rim that is not sharp and they fit tightly together.. i just ordered one ;)

[1800jayd]

This might be a dumb question?

Do you think a super size version of this would work for a portable fire pit? Like a 55 gallon drum. I live in the desert southwest and fire wood is not always easy to come by. I thought a wood gas fire pit might use less fuel for a small campfire? Any thoughts

[guns4toys]

Hello 1800jayd, Larger Wood Gas burners work great. A friend has built a couple of campfire/wood gas stoves from large popcorn tins for the outer can and charcoal chimney starters for the inner can or burn chamber, with very good results. They are very good for cooking and for smoke free campfires. And are extremely efficient with fuel.

It should be possible to build real nice burner from a 55 gal drum cut down to size for the outer can with a 30 gal drum cut to fit for the burn chamber.

[LIFEmimicsART]

Steve, excellent stove designs and video! (And I'll commend you for your patience in repeatedly answering the question "how do you get the inner can attached to the lid?" I was about to ask the same thing until I read your answer(s) :) )

[mgb1954]

You are awesome Steve! Thanks for the videos.

[dizzaeble]

does any one no how to stick the lid of the outside one onto the inside can???

[guns4toys]

Hey dizzaeble, Try cutting the hole in the outer cans lid a little smaller than the diameter of the inter can. Then cut a bunch of slits along the edge of that hole, creating tabs that will bend down a little when you push the inter can through the outer cans lid. These tabs will be spring loaded against the inter can and form a compression type fitting. It does not need to be air tight.

[dizzaeble]

thanks mate i was also wondering how long is the inside can for the mini wood gas stove

[dizzaeble]

does the wood have to be below the fuel jets

[guns4toys]

It will burn best if you try to keep the fuel below the jets. A little tender and kindling above the jets will be ok as it will burn down to the level of the jets quickly.

[hiedi11]

Thanks for the video. Now I have some ideas to get started.

[OldManGlitch]

Perfect video for the information. I can now go home and make one with great confidence. I look forward to the fun and its use. This will save huge money on the woodgas stove purchase I was planning.

[FG37209]

Great vid. We love camping and I've been looking for some project like this to do with my kids. They'll be so proud next time we go camping and get to do some cooking in one of this.

[kaz2664]

great video. i just made one out of a pull top campbell soup can {10 oz.} and a slightly larger 15 oz. hormel chilly pull top can. they fit snugly at the top because of the extra material from the pull top. anyways its small but it works awesome. i realy like the design of the pot holder on the last stove you showed, the one where you can ad more wood.great job. thanks.

[weaselteat]

Great job explaining how you made those! Great craftsmanship!

[romanybob]

The best, most descriptive video I'v seen. Much respect to you!

5*

[KoN312]

Nice Video!

I think my next stove will also be a woodgas stove.

[notbysam]

THANK YOU you are the only one that explained this process completely with sound up high ...FANTASTIC !

[stainlain]

Thanks mate real good instructions.Just from watching your post ill be making a stove soon. Andy,NZ

[macupausini]

what do you use to make the holes?

[guns4toys]

I like to use a Unibit by IRWIN Industrial Tools they are high speed steel fractional hole enlarging bits with many sizes on one bit. And they cut clean holes in sheet metal and cans. You can use almost any drill bit but the hole will not look as precise. And I use tin snips for the hole in the top of the outer can and the fuel hole in the pot stand.

[macupausini]

thank you very much for the answer.

namaste~

[BigMillFO3]

Unibits are prohibitively expensive. Unless you're going to make and sell these stoves or have some other use for it I personally can't justify the expenditure.

[guns4toys]

Hi BigMillFO3, You are right about the cost of unibits they are a little expensive. But you can still use regular drill bits, even a set from the dollar store will work. Or anything to make the holes, you could use a nail to make a small hole then enlarge it with a punch. Or use a church key type can opener to make triangle holes. Building these stoves with whatever materials and tools you have on hand and for no cost is part of the fun. Good luck with your stove build.

[noreastshiver]

The cost of the Commercial camp stove makes the unibit cost moot. And this is the BEST post, video or print, accurately describing the "how to" and "why" I've been able to find in many, many hours of searching. Other people try, but just don't hit the home run you do when trying to educate. I now subscribe, and thank you very much. Real quality video. Right to the point. VBR, Brian

[teb0atoz]

@BigMillFO3 I would disagree when you say "prohibitively expensive", they are only 12$ or you can be cheap like I was and buy the three bit set for 9$. But again I liked the idea of not making burr, not totally true but for 90% of the holes yes.

cheers

[cdltpx]

Great stoves I like the alcohol stoves but have a hard time considering them true survival equipment since you can easily run out of alcohol. But a wood gas or biomass has fuel all over even animal dung can be consumed by these stoves. You did an excellent job describing the stoves and how to make them.

[KungFuChess]

good documentation. thanks

[timfaem]

wonderful vid...we need more high quality vids, as yours is...be blessed

[gescheitert]

you made my day, Steve - gonna try this right away. thanks for posting!

[mnbvczxc]

Thanks for publishing your wood gasifier stoves. Great video. Unibits . . . . I was sure you were machining them holes with something more exotic. Great job.

Ron

[dmacosta1]

excellent video thank you for sharing

[murphtheserf]

Great info.

I'm going to try building one.

[marthale7]

Superb video *****

[pilotg2426]

Great video. Thanks for making it seem so easy:-) I tried making a very small version today, one that fits inside my camping pot. I got gasification but think I've made a classic mistake. I don't think I've made enough intake holes on the outer can as I'm getting quite a lot of smoke and the stove goes out quick quickly. Any thoughts. Can send pics if that will help. Best regards from kiwi land

[yourroaddog]

wich one burns best?

[menso68]

My question is: Can you make a video how you really are making one.

A terrific stove you made.

Menso ( The Netherlands)

[nevahj]

Doh! I just saw the unibits at the end!!

I can't believe you made all those holes so neatly with a hand drill!

Good work. Thanks,

Joey

[nevahj]

Your videos are awesome. Inspired, I quickly put one together and was quite surprised to see it work so well.

It is not as neat as yours so I will be making another soon! However, I have a few questions:

1. How do you drill the holes? What bit? My holes are all torn and jagged.

2. How did you get your holes spaced so evenly? I assume you are using a drillpress, yes?

Thanks again!

Joey

[Leberteich]

Thanks, excellent video, I just built my first wood gas stove following your guidance. I used fire cement to fit inner can into lid, works well.

Do you know some design pronciples, like optimum can Height / Diameter (H/D) ratio? Optimum inner can : outer can proportions?

If you'd use tall, narrow cans, would you get more updraft, like in a chimney? Goes like a fan blown stove, without fan? Any experience?

[hwardoyo]

Thanks for the effort and Thanks for sharing. God Bless You. It's help a lot of people. Best regards from Indonesia..

[4ancientarts]

excellent vid, thanks for sharing your efforts

[borjit]

I am really impressed by the gasifier, the simplicity makes it perfect. I would like to know what kind of welding do you use for assembling the inner can parts. Greetings from Spain.

[guns4toys]

Hi borjit, Thanks for commenting.

I do not use any welding.

Cut the hole in the outer cans lid a little smaller than the diameter of the inter can. Then cut slits along the edge of that hole, creating a bunch of tabs that will bend down when you shove the inter can through the hole.

Pop the can through the hole and the tabs will bend down and spring load the can in place.

[BigMillFO3]

I tried that, cut my finger and ruined the lid. Will likely try again though I can't believe I'm considering purchasing a $40 Unibit when I'm not even sure these are true woodgas stoves, what size they should be, whether I can find the cans, whether I can even get it to light.

[kulnitsky]

good!

one question: what if you add some insulation around the outside can, similarly as in some rocket stoves?

[guns4toys]

Hello kulnitsky, Thank you for viewing and commenting.

I have not tried insulation around the outside can yet. I live in the southern US and it only gets cold a few days a year, so testing the effectiveness of insulation would not be easy.

[MrBillTroop73]

Nice work.

Bill

[skeeter904]

this is by far the best wood stove video on youtube!!!!!!!

[crackahcrackah]

I've tinkered with my wood gasifier and I'm pleased with it. I put too many holes in the inner bottom can so it burned through fuel way too fast. I've replaced that can with an inner can that has smaller and fewer holes to allow the fuel to smolder and slowly release energy. Can't wait to test it. One question. If this thing fully incinerates stuff is it safe to burn oleander or other poisonous woods? It seems safe theoretically but I don't want to make the papers finding out I was wrong ;).

[guns4toys]

Hey crackahcrackah,

Good luck with testing your gasifier.

As for the oleander, that would be to dangerous to test at home, being on the list of most toxic plants known to man! Large commercial gasifiers for processing city waste would probably completely incinerate the toxins, and the gas scrubbers might remove anything leftover for a clean gas output. But I will not be testing any poisonous woods in my burners.

[crackahcrackah]

Thanks for the feedback. I'll steer clear of it. Too bad because the local utility co. has a ton of mixed wood that it collects at curbside from residential areas. Then it shreds it and keeps it on hand to give out as mulch for free...

BTW what is your take on non-fan operated gasifiers vs fan operated? I was thinking the non-fan ones should be able to operate just as well as long as the proper ratio of holes exist for outside air/pyrolysis section/combustion section...

[reginarz]

very good instructions

[geo96929]

Thanks allot! These will help lots of hungry people out there to live a little better.

[pabbananna]

best wood gas stove vdo i have watched over the past hour, bravo!

[423Mark]

I have viewed hundreds of wood gas related videos over the past few weeks and this one is FAR and away the best one for showing how the stoves are made. Thank you for providing such an excellent video on this topic.

[nj4x4fever2]

very nice stove configerations.

[thehikerny]

Awesome job of construction and video !!When you cut the lid off the outer can how does it now become larger so as to as not to slip back into the larger can ? Is it magic? I understand all the rest. Again, awesome job. I have built the "pepsi can" stove and used it for years, looking forward to building and using this new stove. Thanks for your time .

[guns4toys]

Hi thehikerny, Thanks!

Use a safety can opener on the lid of outer can. The Safety can opener cuts lid off from the outer rim, not from the top. And it cuts the rim in half so that the lid can be replaced and it will fit tightly. You can pick up a manual or electric safety can opener almost anywhere kitchen and housewares can be bought, I've even seen them at the Dollar store. Use a regular top cutting can opener for the fire can so it will still have the thick rim around on the top of the can.

[vwdad53]

How do you attach the inner can to the lid of the outer can. Is it JB weld or is it soldered. Great video. Thanks

[guns4toys]

Hey vwdad53,

Cut the hole in the outer cans lid a little smaller than the diameter of the inter can. Then cut slits along the edge of that hole, creating a bunch of tabs that will bend down when you shove the inter can through the hole.

Put the lid on the outer can before you push the inter can through the hole. I usually pop the can through the hole by hitting it with the palm of my hand while holding it in place with my other hand. The tabs will bend down and spring load the can in place.

[welsh58boy]

10 out of 10 very nice the best iv seen here on youtube, keep it up.

[limestick]

well done G4T ...it was very big of you to volunter all this information... others seem to be keeping this sort of info close to there chest!....when really a lot of folks on short money could use these ideas to help out.... you are indeed a gentleman good luck

[jcims]

Awesome video! I hadn't seen these and winged something together tonight with a 16 oz coffee can for the outer and a Kroger generic slim fast steel can for the interior, with a bunch of 3/16th's holes all over. I did the same 'spring loaded' binding for the top, and it's solid. Unbelievable how much extra energy is available in a little bit of hardwood.

Great stuff!

[skaterdude1229]

nice but how did you sticked the can to the lid ??

[guns4toys]

Hi skaterdude1229

Cut the hole in the outer cans lid a little smaller than the diameter of the inter can. Then cut slits along the edge of that hole, creating a bunch of tabs that will bend down when you shove the inter can through the hole.

[NoMoreLTTE]

Thanks!

[godoter]

excellent *****

[johnsmith4king]

Thank you very much

Your videos and your stoves are great

Hopefully I can make a better stove now

I think I was not adding enough holes at the bottom of the inside can for air to the fire

Keep up the good work

You might have a future in video :)

[guns4toys]

Thanks for commenting.

Safety considerations would include using a punch so the drill bit won't slip, wear eye protection and leather gloves. You might need a file to smooth out any rough edges, but not if you use unibits.

Very easy to make at home, no need for a workshop.

I have no plans to market these stoves. I'm just playing with fire.

Burn time can very quite a bit, depends on type of wood and how dry it is.

I see no need for handles, but modify them to suit your needs.

No welding used.
