Hi Heath! I just built one of these off of your plans. I had a slightly different approach to the inner liner removal from the outer: If you use a 150-100 grit orbital sander on the top and bottom (after the bottom cap is removed) you can quickly and easily get through those thin welds. A few taps with a 1x1 piece of wood on the inside on my sidewalk and the base piece popped right off. No burrs/sharp edges and took about 5 minutes. Thought it may be helpful to people in the future!
Thank you so much for showing how to get a thermos apart. I’ve been looking for this sort of video for ages and it’s really helped me with a diy project of my own!
There is a lot of content. The older stuff is not as good quality audio and video wise, but content is worth watching! If you have any question or comment fire away! Pun intended!
You can file sharpen the end of a mini flat head screwdriver and punch pilot holes in the inside and then punch a quarter inch hex bit through those holes while leaving the insulated food jar intact.
The material that pushes inside will definitely effect airflow in a negative way but I’m sure you will be able to make it work! Thanks for the comment!
Great idea! Love to use stainless whenever possible but never thought of this! I like the idea of keeping the screw on top. I took the top from a can of salmon , which was just a bit to large, and cut the edge off with a pair of tin snips. It presses in nice and tight inside the screw top. I put the plastic coated side facing out for weather protection. Screws back on tightly still and gices you a closed container. You can put a small plastic bag of wood pellets in there or a small bag with coffee or instant coffee ir anything else. Just thought I would share that with you! My next gasifier build attempt will be with a one gallon pain can. Will keep you posted. Any thoughts on that would be appreciated. Have a great day!
It will be very good once I have optimized everything! I just tried a heater lid for this stove today and it seems to throw a ton of heat off! Thanks for commenting!
Good work. I thought buying the thermal cup is crazy, as you can buy a stove for not that much more….then I realise I have one or two old flasks that I have lost the top / seal.
Yep, and in some of them, I imagine that the vacuum has already been compromised (dropping these can do this, as they are under tremendous atmospheric pressure (about 6 miles of more dense/heavy air, but then a lot more atmosphere besides that).
Can you tell us the size. And number of air holes? Primary (I.e. Lower holes in outer canister), bottom of combustion can/chamber and the secondary burn air holes in the upper inside wall of the burn chamber. Even if you haven't reached the final version, it would give other experimenters a good starting point.
That’s a great idea! Sometimes while I am working and recording I don’t always think about the best way to demonstrate to the viewers! Thanks for the comment!
Hey Heath! Watched your whole series on stoves man, i feel like i know you by now ahaha Please check ou the pyrolino stove. It's way too big and heavy but you can take some ideas off of their design. They used a vortex as well to help combustion, but only after a tertiary vent hole. They also use a very long chimney, wierdly enough that results in a completely clean burn without any soot. Greeting from Portugal
I'll have to re- look at some of those ice bucket/wine coolers that are similar to this but larger in size. I had been wondering how difficult they would be to get apart...
It runs hot and is a little hard to simmer food with, but I have a cooking video with a paint can stove that is built with a dampener and simmers much better. The fire lasts about an hour if you include the char burning phase. Thanks for watching!
I think you may be overfilling the fire pit bit with too many pellets. If you just cover the bottom and light it you will create the thermal flow needed for these to work efficiently. At the moment the fire is sitting too high up the burner so the gasifier principle can't happen.
I could start with just the bottom covered, but then either the burn is very short or I add fuel and that not only breaks the pyrolysis zone and causes smoke and now it is no longer a TLUD stove. If I have this wrong, please elaborate. Thanks for watching.
For smaller stoves 3/8 maximum. 1/4 seems to be a sweet spot. Since the flow is natural and not forced air any smaller restricts the flow too much! Thanks for the question!
Easier yes, by not as accurate. The secondary holes need to be as evenly spaced around the can as possible and the stainless steel they use is very tough. The primary holes also must be evenly spaced but not quite so critical. It is also very nice to be able to open this up to clean occasionally. Thanks for the question!
@@heathputnam9524 in addition: i guess the amount of secondary holes should be more than the primary (outer holes), right? That would be difficult to accomplish without disassembly
@heathputnam9524, at the point where you’re filing to remove the bottom, it may go faster if you treat it like you have a can of food and no opener: just rub it in circles on a sidewalk until the bottom comes off.
You wouldnt expect to "see" or hear anything from any vacuum: you are only slowly shaving away the metal so chances are that only the smallest of pinholes form and that is just too small for any air to make a sound, but enough to fill up the space quickly.
The only way you can really tell is by listening for a swooshing sound and feeling a pressure change (there should be a very slight expansion to the outer cylinder).

Awesome tip! Thanks for the comment!
I was just looking at this item thinking it would make a great sized stove, would like to see more updates thanks!
Did you try to make one? Thanks for the comment!

Glad to help!
best burn I seen so far on these kind of stoves and seen a lot of them
Thanks! And thanks for watching!
Awesome hack/modification. Thank you for sharing.
Thanks for watching!
I was thinking of doing this but didn't know how to remove the inner part. Thank you for sharing. Time to go buy more of these can coolers :)
I’d love to see the finished stove and a thorough build video. I am new to your channel. But I really like this video and will look for more

Now you know that is just genius. Of course I would love to see the build, if you may.
I bet that would give off a decent amount of heat, too?
It will be very good once I have optimized everything! I just tried a heater lid for this stove today and it seems to throw a ton of heat off! Thanks for commenting!
@@heathputnam9524 A heater lid? Dang, I didn’t know such a thing existed.
Thanks again for sharing.
Maybe I’ll do a video on it! 😊
@@heathputnam9524 👍
🙏Respected sir thank you very much to make a small thing a big project🙏.
Thanks for watching!
Cool and informative video. Thanks. You've got a new sub here.
Thanks for the sub and watching!
Awesome thermal stove Heath!
Thanks!
@@heathputnam9524 You are very welcome! :)

Awesome idea!
Thanks for the comment!
@@heathputnam9524 it seems like it’s got a lot of potential, can’t wait to see it when it’s done :)
Thanks for watching!
That's the micro I was thinking about. 👍 Plenty of ss thermos bottles to be found in second hand shops. Thanks.
Hey small stove guy! This should work for you! Thanks for watching!
So many indeed. Dad picked up a the yeti version of this cozy for 25 cent at a yard sale the other day.

I’ll see if I can do that before or in the next video! Thanks for watching!
I would never guessed how to get that apart..
I was wondering if you were going to roast a chicken leg over it lol
Thanks again😇😂
My cooking video got very few views such apparently people want science not sustenance! Thanks for watching!
I would like to see the full build on this can you send me a link?
GREAT video ...dont shoot me for saying but would have been easier to fathom if one of the cans was sprayed a different colour. Class tho.
That’s a great idea! Sometimes while I am working and recording I don’t always think about the best way to demonstrate to the viewers! Thanks for the comment!
What do You think about using thermos that has already two walls of stainless steel and modifying it to stove ?
Yes, it should work as long as the space between the inner and outer walls is at least 1/4 inch (6mm). Thanks for watching!
Gotta add a lid to the top so it can store stuff in. Matches lighter or pellets
This one still retains the screw on lid so you can store stuff! Thanks for watching!
The vacuum doesn't escape, air goes in. just sayin'
Thanks for the comment.

Thanks! I watched the videos and think it can be improved and made a DIY project!
I'll have to re- look at some of those ice bucket/wine coolers that are similar to this but larger in size. I had been wondering how difficult they would be to get apart...
I wonder if a 30 oz stainless steel tumbler would make a great wood gas stove?
It should if the walls between the inner and outer containers has enough space for air to flow freely! Thanks for the comment!
Thanks for an awesome video. How well does it work for frying and cooking? How long do the fire pellets last?
It runs hot and is a little hard to simmer food with, but I have a cooking video with a paint can stove that is built with a dampener and simmers much better. The fire lasts about an hour if you include the char burning phase. Thanks for watching!
I think you may be overfilling the fire pit bit with too many pellets. If you just cover the bottom and light it you will create the thermal flow needed for these to work efficiently. At the moment the fire is sitting too high up the burner so the gasifier principle can't happen.

Nothing this small but walmart now has wood gas stoves on the shelves.
Good luck with those. ;) thanks for watching!
I've wondered for some time, what if you made a tall stove? 1 to 2 ft tall.. Would the air become super heated?
I think it would work! Give it a try and let me know! Thanks for watching!
Hey Heath, is there an ideal distance between the fire box and the outer container? Is narrower or wider better, or does it matter?
For smaller stoves 3/8 maximum. 1/4 seems to be a sweet spot. Since the flow is natural and not forced air any smaller restricts the flow too much! Thanks for the question!
@@heathputnam9524 This is double interesting since a non insulated air gap of about 1/4" is also about optimum (for insulation purposes).
Are you going to make this thermal stove adjustable?
I’m not sure yet. It depends how much interest in this stove. Thanks for the comment!
Awesome video. But wouldn't it be easier instead opening it up just to drill few holes from outside and from inside (obviously with an angle)?
Easier yes, by not as accurate. The secondary holes need to be as evenly spaced around the can as possible and the stainless steel they use is very tough. The primary holes also must be evenly spaced but not quite so critical. It is also very nice to be able to open this up to clean occasionally. Thanks for the question!
@@heathputnam9524 in addition: i guess the amount of secondary holes should be more than the primary (outer holes), right? That would be difficult to accomplish without disassembly
Yes you are correct!
The holes in the bottom of the inner container are primary holes. They should be about 4-5 times as many as the secondary holes… thanks for watching!
Does anyone know the name of the song played by the fiddle? It was a great song!
There is no vacuum involved with that cooler. It's just a basic double-wall design.
Thanks for watching
Very nice.
But it seems that you skipped the process of making holes.
So how many holes in the inner cup and the outer?
Please watch both parts. I think it is all explained. Thanks for watching!
Thanks

Work on not saying, "Uh" repeatedly when you talk.
Uh, sorry…
how would you want to "see the vacuum" with your eyes xdd????
