I used the drum out of our old washing machine. No cutting, no drilling necessary. Just build a brick pit, slot the drum in, and lift it out to clean. Perfect.

Use a carbide hole saw when you drill into stainless. Also, when drilling metal you want your drill spinning slowly but you want a lot of pressure. It allows the hole saw to cut chips out rather than burning a hole.

Learning from your design, I used the Mainstays Stainless Steel 8 Quart Multi-Cooker Stock pot with Lid from Walmart (cost $14.98). I only need to drill holes 2" from the bottom of the main pot, then put the steamer on top. With 6 cups of wood pellets, the fire was last for 1 hour.

We have something similar in our backyard, using the stainless steel drum from a washing machine. Works fantastic!

Great vid, very creative. Appreciate you showing all the impediments you encountered along the way and how you got around them.

I appreciate your way of disposing the debris, see a nice soul cares about environment.

Excellent tip on the tinktube, been a contractor for over 30 years and have not seen this brand. I see a step-bit as a go-to as well, yours looks like a big box store or harbor freight one (same quality really). When I stepped up to a Milwauki step-bit it was a game changer.

Great build! For drilling holes in SS, use slower speeds & lots of pressure & cutting fluid. Also, they make a hole saw that has carbide teeth, there expensive but work amazing at going through SS!

The handles you took off the small pot would make a great pot stand!

I appreciate your interest and desire to do things in a more "green" manner. I built a melting forge a few years back and followed the same principals. In doing so I found that the stainless pots at my local walmart were all made in china. Not exactly the greenest option available. Instead I scoured my local re-use centre until I found the sizes I needed. So instead of using dirty stainless steel made in china and then shipped all the way over here, burning oil the whole way, I used domestically made stainless that was easily 30 years old and had already served a long life before I gave it a second one. It's great to do something as simple as saving the aluminium shavings to properly recycle them but we can do even better by being more choosy about our initial starting materials.

For deburring the holes get a flap wheel instead of a hard stone disk. They're made from layers of sanding paper and work much better on ragged metal like you had from the step drill. Usually around $4 dollars at Harbor Freight or a Big Box store.

I just use an old clothes washer tub as a smokeless fire pit. They have all the hole pre drilled burns smokeless and it is perfect size for camping. It sucks on air from the sides through all of the holes. You can see jets of flame form as it re burns the smoke vapors and burns clean after a few minutes.

you can make mini versions of this with different size food cans. It's a great way to get the hang of the concept and all you need is some recycling, a hole punch and some tin snips, or a swiss army knife. Even ones made with standard food cans will throw out enough heat to cook for one person on, and only needs twigs or pinecones for fuel. That being said, now I have a place with a garden I would love to make one this kind of size for chilling around on summer evenings

That was a great build and it worked well.

9:13 With just the tools you had, I’d have used the hole saw bit to drill a hole in the middle of the wood (you used to punch a deeper divet with the screw) at the end. Being the the step bit was smaller, the wood would have made a surface to press against, stopping the pot from deflecting, leading to a cleaner (no punch out on the inside) and cooler cut. With the step bit having a surface to fight against, it would have cut away more material instead of heating it and pushing it inside. Just my 2c 😁 The design is quite nice, I really like it.

Really nice build and it looks like it works really well! Glad to see you back again too.

Thank you, I'm watching from Papua New Guinea and I am very happy

Many thanks for going through the trouble to film your work, much appreciated and really grateful

GreenShortz DIY, while I don't give a damn about the environment I can definitely see that you know what you are doing. Changing to the Step Bit was the right call. Thank you for the video.

Great to see you back! Amazing what the right tools in the best shape can help you accomplish! This project is above my tools and skill limit, but I enjoyed watching. I figure, eventually, when I understand the concepts...then maybe I can build something of my own.

The only thing I would add are lock washers on your nuts and bolts because I have made some things like this and the expanding and contracting from heating and cooling caused things to work loose and want to fall apart without constantly keeping things tightened until I added lock washers which stopped the problem for the most part. Otherwise double up your nuts and tighten them down on each other works good too

Spray the outside of one side of the pots with high temp flat black paint, and it will radiate out heat much better on that one side. The flat black (or other color) has less "emmissivity" so radiates much more heat where you might want it on a cold day. Rather than polished chrome color.

Thanks, man. This will be my next father n' son project in the weekend.

Really cool! Love how you try to be green where you can, as well.

Knowing full well that you are very talented, i still would like to offer a couple of tips. When filing, especially a hard material like stainless, you only want to make forward strokes. Drawing a file backwards can flatten the grooves. Secondly…the next time you need to punch a big hole in metal like this, you may want to consider a knockout puller that makes holes for electrical fittings.

Great stuff. Inspired me tremendously.

FYI No hi RPM’s with stainless… Toss the uni-bit. Use cutting oil and your hole saw. Pulse the drill on & off, go slow as not to heat up the stainless steel. It will go through like butter after a few slow turns.

Yeah man you were my hero putting granddad's oil on the jig saw cut line. As you've likely had commented, stainless likes it's loving slow. My dad and brother were installing security bars on gas pumps for a client. They went though so many drill bits. There were going through sheet stainless. Unfortunately they had a corded drill they used at twice the speed of light, I'd imagine. One day my brother said they had one pump to do but Dad was busy with all the tools. I worked alone with my own business. I said i could go by with my step bit and cordless DeWalt. My brother said he doubted the cordless could do it but we could see. On speed one my step bit crawled right through the sheet like it was nothing much to his but not my surprise! Yeah it takes some lessons but you'll learn slow gets you all you want from stainless with just one new bit and a little oil out of respect. Ha. Great job making you're own stuff! Feels good, doesn't it!?

Pretty neat, I might try this. Thanks

I have a stainless steel washer drum… zero cost and works like a champ

Thank you. That was awesome. I am going to make one. Thank you

Always enjoy your videos thanks for all the good ideas❤.God bless you and yours

Like it! Good job. Carbide bits and cutters are easier to use on stainless.

Awesome build! Making one!!

This is so cool. I will make similar one.

Cool piece of kit!

Ooo! thats a nice looking burner you got there, nice one

It's a good idea. You did a great job.

Great idea! The company Dancook has even built a smoker with this principle of air supply. I have one of these and it doesn't use half the charcoal that it would otherwise. I think this oven would then have to be similarly economical. Greetings from good, old Germany 🙂

maybe make the opening smaller on top, add smaller pieces of wood and light it from above, the wood should not keep burning itself but it should create lot of gasses, that are sucked into the outer shell heated and rise and mix with air and light the gas again on the top. works perfect with wood pellets.. you will get only flames from the top if it works perfect. but for pellets the holes are now to big, you could add some Stainless mesh to make holes smaller

Very cool project. I might try this one myself

Well done man! Love the legs. Really cool to see it work right off the bat!

If you grab another pot drill holes in it. Then wrap it around the bottom air holes. Your stove will have an adjustable flame. A ring binder handle will help you move the flame adjuster around.

Rev the drill when using a hole saw in SS. Don't aim for a high speed cut and use cutting fluid, it keeps the heat down and yr hole saw lasts longer 😁

Great idea with green tips

It would be nice to make it ADJUSTABLE for firesize. Raising or lowering the upper pot would restrain the intake air, AND the secondary air flow. Maybe making the flame size adjustable. Curious to see. Thanks.

I Love it... nice job

That is a very nice cooker and nicely done

Welcome back Tom. This was a nice video. Great way to repurpose scrap tinktube pieces into another project. Infinite adaptation. I’m sure you can find a circular wire grill to cover the opening. In future, when drilling into flexible metals, the wooden base is a better idea. Use the hole saw to drill a 1”+ hole in the 2x4. Place pot over the hole and allow the wood to support the sides while you perforate the metal. You need to add toes to your “Eyes and Ears” mantra. Just trying to keep you safe out there. Wishing you and your family another blessed week, gentle autumn weather and restful evenings. Peace brother

I knew someone would figure this out sooner or later

This big version .. 🍺🍻great work.. love this ❤🙏👍

I'd use Greenlee hole punches for the holes. They are designed to make holes in electrical boxes and should be able to handle the job easily.

I'm gonna make one. Nice video.

I had make one it’s worked amazing. Great ideas. 👍❤️ Thanks mate! 🇦🇺

Nice One i like building stoves myself too👍

Genius 👍👍👍👍

I did something similar when making a rocket stove from a coffee tin. I printed out the pattern for the holes on sheets of paper pasted on to the surface of the tin as a template for perfectly spaced and even sized holes. I also had to punch a pilot dent with a nail and then drill successively larger holes. Since my surface was covered with holes, I had to support the inside with wooden 2x4's in order to stop bending and misshaping the stove. The correct way to punch those holes will be with a hydraulic punch but that was outside of my scope of operations. The alternative to your brackets would be to find any metal pipe that will fit snugly between the two chambers and cut that into 1½" segments riveted from the outside of the outer chamber on the bottom and sides of the outer chamber (3 on the side and 2 on the bottom) allowing the inner chamber to slide into place with a little play to allow for warping and expansion when hot. For a pot-stand I would take a standard diamond-shaped metal grid cut to size to cover the top and with L-brackets attached on the edges to stop it from sliding off. I would make second grid that will become greasy by placing meat and sausages directly on for grilling. If you cut thicker logs to less than 3" stumps you can get some coals going for even-burn cooking though charcoal will also work. You might want to experiment with a system where you can slide in a removable radiator of copper tubing between the two layers to create a hot-water system when camping. To set your stove on fire you might want to experiment with cotton balls covered in petroleum jelly (vaseline) where you can light the ball and drop it onto your tinder comprising of leaves, twigs and paper crumpled into balls. You can store fire-starter cotton balls in a jar that is stored inside of your stove when not in use. I have been regularly using that stove using ethanol-based gel-fuel (similar to Covid hand sanitiser) for the past fifteen years. The fuel is placed in an empty tuna can suspended on a wire platform about a third from the bottom of the tin. Alternate fuels I have experimented with where alcohol spirits and diesel or paraffin into a tuna tin filled with sand to regulate the burn.

Brilliant !

I was thinking of a grill or pot standoff. I'm gonna try to get mine through second hand sources. I'm almost done with a smaller stove using cans.

Harika video için teşekkür ederim. 🙏

Thank you so much sir.

Awesome build! And I am only teasing when I say nice flip flops safety 3rd. Thanks for sharing.

thanks for sharing the work. 😉💚💚

Not sure if you know this but typically, when you cut or drill stainless steel you use water as a lubricant. The water absorbs and dissipates the heat and makes cutting or drilling easier and faster.

Perfect ...

Super cool! Well done!

Idea: Drill ventilation holes in the inner pot close to the bottom. Before cutting out the bottom from the outer pot - drill first many ventilation holes. Add 3-4 bolts as spacers. After use it as removable bottom in the inner pot to improve and even the supply of oxygen 8). Thank you. TY

If you paint the outside of the stove with a high temp paint of some kind, it will radiate more IR through.

Great to see that more people care about recycling even of small amounts of metal. I thought I'm the only idiot who picks up every nail and put it in the metal recycling ;-) Many greetings from Germany

This is awesome, if I wasn’t so lazy I’d make one, but for now I’ll just buy one that is ready to go 😂❤

Good project

Very creative, love the idea. I wonder if this could scale up using a stainless steel 50 gal drum

I think it's a downdraft gasifier, and that the holes in the bottom are actually pulling smoke out the bottom, the hot air in the side wall rises with so much energy, it creates a tremendous vacuum that's pulling air in from the outside at the bottom AND drawing air OUT the holes in the bottom of the burn chamber. The stuff that burns the hottest, those gases go out the top, but the incompletely burned gases (smoke) are less energetic and the vacuum's enough to pull those gases out the holes you drilled near the bottom. There's still a lot of smoke from the fire in the chamber. It just doesn't escape out the top. It mixes with fresh air and emerges around the rim at the top, where it's ignited. I don't think the holes drilled in the bottom let air in, but rather re-direct the smoke out the bottom and into the air flow going up the side wall.

So cool

Genius!

Too much hard work thanks for this video sir🎉🎉🎉🎉👍👍👍👍

Could you try and test one optimization? One of the things I've learned is that shiny surfaces are not good at radiating heat; the more dull and non-reflective a surface is, the better it is at radiating thermal energy. For this reason, if you rough up the inner and outer surface of both pots (for example, with sand blasting) and then spray paint all but the inner surface of the inner pot with heat resistant black paint, your smokeless fire pit will become much more effective at radiating heat from the fire, making it more effective at warming the folks sitting around it. Otherwise, most of the heat just rises up and away as hot gases, with minimal heat radiating to the people around it. I'd like to see what you think of this optimization. I would like even more to see it tested side-by-side with what you did in this video, as a test of whether or not this optimization is worth doing.

Amazing

Great job! Thanks!

i bout 16qt and 20qt for 49,90 this going to be amazing project!! thank you!!!

I love your smokeless fire stove

Thank you 😊

I just saw this video that says clay can be made insulative by mixing in little grains of charcoal, the size of pebbles. When the clay is fired its charcoal burns up, leaving behind air gaps. About 30% of the mix should be charcoal, and another 30% ceramic powder.

That's a very nice looking fire, and very neat job. I want to ask something if I may, if you put some sort of pan or wok holder on the top and use it like a stove, will it disrupt the airflow and making the fire smoke?

Good job !

I wonder if you make ice in the pots that you want to drill- adds stability and cooling.

Nice job!

Amazing how Jurgen Klopp finds time for such trivia while competing in Premier league! Respect.

Great job 👏

Great video.😊. Thanks

If you have a grinder, and a cutting wheel, you can sharpen the cutting edge of your stepdrill after burning it up. You will get a bit more life out of it before it is junk. Better than recycling, is resharpening. I saw a video where a ceramic sparkplug was used as a friction drill, heating the metal to red and forcing the metal out of the way to form a hole. This leaves a very heavy sharp burr, which can be removed by grinding, or is good to tap threads into, due to the longer threaded length.

I like the fact you use WHAT YOU HAVE IN THE TOOL SHED, AND SHOW USE YOUR MISTAKES….THATS COOL

Excellent

This is a gasification stove or fire. I built one similar to it using an old drier drum and a smaller inner pot. Mine had the inner drum up against the underside of the outer drum, and about 50 smaller holes around the top of the inner drum two inches down. Because so much air could get into it, when it roared it ROARED!!! And because of the inner dynamics of the drier drum, the flames travelled in a circular motion. It also chugged like a steam train when it got really hot, lol. You can also build a smaller version of this that will fit in a backpack using an old dog food can and, or an old can of beans or corn.

A DIY Smokeless Fire Pit From Cheap Stainless Steel Pots… love it!

Greetings! I've watched over 25 DIY videos on this but yours I keep coming back to as a guide. In the last 2 weeks I've built a few of these at various sizes. Each build gets better. Being smokeless has been achieved. I'm not happy with the build though. Getting ready to go now with a 20l oil tin and a 15l stainless steel stock pot. What would you improve on doing this again? Specifics will be greatly appreciated! Give thanks for the video. It created a firey passion in me for creating such beautiful art.

I've heard when drilling hollow containers you can fill them with wet sand i think the holes stay clean

dewalt makes the best step bit, as pre "project farm" channel. i use the step bit to clean a chamfer the holes from the inside. you must be very careful. i have a hydraulic hole punch i with try not sure how it will do on stainless steel and the round shape doesn't help. thanks for the project, i was thinks of trying something like this.

Please include green tips! Love them

to make metal like that easier to drill you should have used the wooden board for support it would have kept the metal from flexing and provided a backstop, just screw down some sacrificial wood to the top of the good board drill a couple holes, it would also make the hole saw bit work better on the pot, although you can still use the step bit if you wanted to, then when the wood looses structural integrity, take off the sacrificial wood and screw another piece of scrap wood to the good board.
