you really made the best diy camping stove video....the minimalistic silence made one focus on the instructions which are clear and precise....a work of art.
Perfect Guide to make one of these! Especially for the time at which it was released. A few tips from someone who has tried one too many designs: - The bottom of the burn chamber can be simple steel mesh. - The outter can vent holes can and should be above the burn chamber's bottom, to improve gasification. - You can use a much taller pot stand for a rocket stove effect. If you want a more complete combustion add tertiary combustion holes in the middle of it, and flame exit holes at the top. - Add steel mesh right under your pots if they're too thin, it distributes heat nicely. If you use food grade material it can double as a grill. - use a flame concentrator if you can go through the trouble (like the sides of a rounded bowl) to focus the flames on the inside, improves efficiency - Tilt the secondary burn holes and add a metal fan on top to improve efficiency and reduce soot - use an air input spinner to further improve vortex effect. look up "fire vortex demonstration" on YT - For a large version I used a double walled ice bucket. - IF you don't want to get addicted to making these, DONT START! just like it happens with DIY alcohol stoves, It's a Trap! Just buy the Ikea utensil strainer and use it with a pot that nestles nicely with it.
Forgot to say, instead of drilling out vent holes, just cut them squarely and leave one side uncut, so you can essentially have a metal flap to guide air into the outter walls or into the burn chamber. That's the easiest way of making a vortex wood gasifier stove. Doing just the secondary burn holes is fine, but doing the outter can ones also helps.
This is one of the best "how to's" yet. I like the absence of music (noise) and that you demonstrated the finished product before we watched the build instructions. The list of tools is appreciated also.
One on a million videos that really shows someone who knows how to work on cans for make a perfect woodstove. A lot of "bushcrafter" don't understand how to make and how to use a pyro-gasifier stove!!
Nice showing operation of the finished product before going into the build . A major thank you for not rambling on for five minutes at the beginning about why we (who have already sought out this video) need to be convinced we want to do this.
Finally after seeing so many so called simple tin stoves this is a truly a simple tin stove thank you so much I paid £120.00 for one and after using it once a day for a year it broke so thought of using tins instead and save wasting money on a fancy one.
Just made one with your instructions. Love it, it has lots of air and heat. This is my second diy wood gas stove. Before I built a smaller one with a 300g and 400g can after the instructions from the channel Outside Edge Bushcraft. That is also very good - for making 2 cups of coffee + bacon and eggs in the morning or on a little walk as a portable small solution. But this build here is much more powerful, even though still not too big, one can use a real frying pan or cook pot with this and probably make a proper lunch for more than even 2 persons. I just made the cooking test with 8 fried bratwurst and 1 liter boiling tea water. Thanks for making the video, I searched long on youtube for a powerful design (like a silverfire wood gas stove or so), yours is the best I could find!
Good, solid design! I especially like the fact that you 'batch load / then top-lit' your wood gas stove, as opposed to 'bottom lit / then load' -- one of the very few that I've seen done correctly on RU-vid... Thank you. I've made a few of these myself and tend to be a little more critical about primary-fuel / secondary-air ratios, air/fuel mixing & their dimensional relation, heat retention, least material removal from tin can for assembly strength and rigidity , and of course aesthetics, i.e. form following function. A well done fundamental tutorial.
What a great stove - I just made one this morning after watching your video, I've fired it and put it out 4 times with sticks and leaves (and a few too many matches - it's a bit wet) - I noticed that I can pick up the stove because of the separation between the cans - it does eventually get hot, but being able to move it around is nice. I didn't follow your instructions exactly but I think I got the basics of airflow and the afterburner. I have an observation (not a criticism) - I noticed when I have a good hot coal bed, if I put a long stick or two in so one end is down on the bed, I can see the syngas (or whatever you call it) coming off the stick, and after a certain amount has collected on the bed it seems to then heat up and rise to burn - kind of neat to watch. Thanks for sharing this video.
This is wonderful!! Thanks for showing your design. I've been wanting to make a better quality cooking stove for the homeless (and for camping) for a long time. I have been making them with the old styleplan: coffee can, soup can, and tuna can /cardboard fuel cans. I knew there had to be a good DIY plan for a gassifier can project, and yours is perfect.
Great video! Thanks for making it. I plan on making one. Can't argue with cooking with a cast iron skillet. Just a thought off the top of my head. I'm going to try finding a tin can slightly larger then the outer can, and then cutting that can into a pot. Then the pot would pack right onto the stove. Keep up the good work!
Thanks for the kind words! Regarding the can pot: ounds like an excellent idea! Given the plastic linings inside many cans, it might be a good idea to burn it off first. Please report back how well it works out!
Thank you for sharing this video! I loved it! Great job! Everyone is America needs one of these things just in case. One in the backpack and several stashed around the house. If nothing else we need to be able to purify water. We just got a letter the other day from the city we get water from saying the water was not fit to drink boil it. I think my water bill is a bit high to have to do that.... anyways... Thank you.
As per most comments, great vid, no talk, simply well filmed instructions of build & function. The only thing missing is cooking up a meal with the contents emptied out of all the cans! Bacon, eggs, coffee impressive at the beginning, full meal with contents would have been an epic epilogue!
This video is informative as fuck. Extremely good production and direction. The forethought and mindfulness that went into not only the creation of the stove, but the video as well, is impressive to say the least. My only critique would be that the tools necessary to complete this job was not displayed. Not everyone knows what tin-snips are. Quality fucking video.
Thank you so much for the feedback and kind words! Future videos will take your critique into account. Meanwhile, the description underneath the video does include a tools list. Thank you again - and for watching!
Yep, it works! It seems to have some problems with damp wood though. But that's not a design flaw, that's my lack of fire making skills. Guesss I have to practice a bit.
+Hendrikjandespeelman Always good to read of success! Regarding the damp wood: no, it won't work well with that. With dry wood, you should quickly get the "feel" of the stove. Thanks for the report and for watching!
Wow. I have made many tin can stoves, and I have some quite good ones; your design for a DIY wood-gas stove is the best I have seen so far. This is an excellent video of an important, true, DIY project. Most excellent! *sub* P.S. (I'm no cardiologist, but I hope it was just for demonstration's sake and you didn't eat all that bacon grease with your eggs! :D)
+StandsWithABeer Hi! Thank you! Comments like yours are most encouraging! Regarding the bacon grease - there was a bit much, but didn't want to empty the pan after the bacon for video continuity's sake. Of course, you do realise you're getting awfully close to saying it's possible to have too much bacon. :-)
Fijn ding. Morgen eens wat blikjes kopen. Ik zal je laten weten als het gelukt is. Dan gaat het mee naar Schotland voor een hike over de Cpae Wrath Trail.
I'm back ! I do not know what part of the world you live in , BUT the sizes you have given for the cans is not available in FLORIDA , USA I sure wish I would have investigated the no talk jerk before giving a thumbs up !!!!!!!
I do not generally thumbs up a video where the maker does not know how to talk....but I have your's it sure seems like a good build , something for me to try.
This is quite interesting. I've never seen a gasifier with a 'grill stand' before. What made you decide to try it and have you used the stove without it?
How many times have you used the same stove? I'm wondering what the life expectancy of the tin cans will be. It would be good to know if one stove will survive multiple uses, and thus be reliable for multi-day hikes.
Hi! I lost count after a while. But my stove has lasted many dozens of firings. I expect the pot stand to require replacement at some point, but thus far it's holding up well. Hope this helps, and thanks for watching!
+John L Bales Heh, was waiting for someone to notice that. :-) It was all I had on hand with the oh-so-convenient shallow curved profile. The metal files I have are either flat, triangular or round with a radius too small to work the metal without leaving "divots." Given how soft the can's metal is, I risked it. Pleased to say the rasp is none the worse for wear. Good eye - and thanks for the kind words, and for watching!
Apologies for the tardy response ... We've used it many dozens of times, and it's still going strong. At some point I anticipate maybe the grill or pot stand requiring replacement. But that seems a while away still. I wouldn't want to paint it with anything as I'm unsure as to the vapors that'd be released, possibly being unpleasant or tainting the food. Besides, it's an added requirement, moving away from our minimalist desires. The cans themselves are, after all, recycled trash! :-)
Thank you! Have been using just text as it's feasible to pause and translate for non-English speakers. Maybe soon with the explosion in AI, this'll no longer be necessary! Thanks for watching.
+Adrien M Thank you for the compliment! The design evolved through experimentation with prototypes (great advantage of this design is the exceedingly low cost of materials :-) ). Thanks for watching!
Humans made fire. Now it's been updated. This is possible with mud. We can evolve. You can get woodburners that do this. Prep for the future. It might not come in our time but just in case let's help our kids and grandkids just in case. 🙏🙏🙏
James Smith Hi! They're called a step bits. They're convenient in that they have multiple sizes on one tool. But further, they generally do a good job making holes in thin metal (regular bits can leave ragged edges). Good quality bits can run up to a few 10s of dollars in the US, but they last a long time if not abused. If you've not made anything, it can be a good first project. While some details might be challenging, the raw material is cheap (cans which would have been discarded anyway). Mistakes in cutting/drilling will not be expensive. The biggest issue is safety. It's easy to cut yourself on metal shards and shavings. As always, know how to use the tools and protect eyes and hearing (along with fingers and other body parts). If you know someone who has some experience with such tools, see if they are willing to help you get going. Thanks for watching!
Hi! I'm afraid we have no direct experience there. I'm sure it's feasible, albeit with adaptation required for different dimensions. Thanks for watching!
Excellent video. Well done. One question - at 5:30 what is the purpose of the grill piece that drops to the bottom of the firebox? I haven't seen this used before in any other video.
Max Headroom Hi! The grill suspends the burning wood, allowing air to flow up through the bottom without needing to suspend the stove itself. Also, it allows ash to fall through, preventing or delaying any choking effect an ash buildup might have on combustion. Thanks for watching!
Hi! Mostly just by estimating and bisecting. It's easiest for powers of 2 counts around the circumference (2, 4, 8, 16, etc.). Make the first mark anywhere. Eyeball the second to be opposite the first. Then eyeball a mark on each side equidistant between the first two, and so on. Non powers of 2 counts are a bit more difficult. But again, just eyeball it - exact spacing is not necessary. Hope this helps, and thanks for watching!
By now I've seen a few other vids on how to make this and I've come back to this one and I'm pretty convinced just by looking at it, and by looking at it burn and how perfect it is, that this is the best design and this is the one I will go with. I am just going to buy a step bit and some tin snips, will medical shears work ok? I'm probably going to simplify the whole process by eyeballing everything. What cans do I need? Can you find the cans you used to do this on Amazon and post the links? Or? I'll look. I'll let you know if I find them and then maybe I'll post the links. :) Thanks again!
James Smith Thanks! Regarding your questions: 1) Frankly we don't know what medical shears are, so we can't answer that question. 2) We recommend rather than mail order (where you can't see beforehand what the cans' shapes are), you go to your local grocery store. There you can walk around and test the cans' sizes against one another. Please let us know how it turns out. Thanks for watching!
+DudestDude Hi! While we don't have a clear answer for you, we doubt it would be very effective for melting aluminum, given its relative compactness. Thanks for watching!
Hi! Near the start of the video (roughly a minute in), where the cans are displayed beside one another with a measuring ruler before them, their dimensions are given.
+Alexander Kim Copying a response we gave earlier in the comments section: "The grill suspends the burning wood, allowing air to flow up through the bottom without needing to suspend the stove itself. Also, it allows ash to fall through, preventing or delaying any choking effect an ash buildup might have on combustion." Thanks for watching!
this is a great design and I think it's going to work out really well. although there is one issue. a step drill bit costs $50. so drilling a 3/4 in isn't very practical. I would like to see this modified for a 1/2 in hole.
You can buy a step drill bit for pretty cheap. I got one for ~$6 from Harbor Freight just to make this stove. If you google search "Titanium Nitride Coated High Speed Steel Step Bit 1 Pc" (no quotes), you'll find it in the first result. Good luck! :)
Hi! We've found no reference indicating food grade cans contain zinc. Indeed, apparently zinc is avoided for reasons of potential toxicity. Also, as these aren't barbecues, the flames don't impinge on the food, but on the bottoms of pots. Finally, variations on such stoves are popular, and were there any toxicity, it would no doubt have become known.
can someone please explain to me why all these vids are made claiming wood "GAS" there is no gas there dam wood stoves......there is no secondary combustion chamber they are well ventilated wood burners NO GAS!!!!
+vanisloo Hi vanisloo. The process is known as wood distillation or pyrolysis. A more generic term is wood gasification. The heat does indeed release a flammable gas from the wood (carbon monoxide and hydrogen), which in a "normal" fire is wasted (released in the smoke). A Google search will yield much information on this subject.
Too many and too large holes = poor air control = yellow flame + high fuel consumption Fewer smaller holes = better air control = blue flame + lower fuel consumption + more heat
+umvhu Hi umvhu! After having made quite a few variants while developing the one shown, my experience contradicts your assertion. Also, quite a few others have had success with this design. Have you a link showing your design functioning as asserted? Thanks for watching!
this video is absolutely fucking ridiculous. number one i went throug about 6 months of canned food trying to make it then i had to hire a nasa engineer to finally make it
