161. Easiest Tin Can Rocket Stove Hybrid - No Drill Required.

so welcome back everybody today I've got a variation for you on the age-old tomato juice can rocket stove or stick stove so I'm sure you guys have seen these on the internet or possibly built a bunch you know over the years yourselves and what are we talking about essentially taking a 48 ounce tomato juice can and turning it into a wood-burning stick stove or rocket stove so typically what you're gonna see with this kind of a stove is you know obviously popped the top off poke a bunch of holes on the side it sticks in the top and light it and you're good to go maybe you know cut a little bit of a relief out of the side so that you can feed the sticks and into the you know kind of the top at an angle without actually taking your pod off so you know what I've used that type of stove soup cans coffee cans and they work pretty well today I wanted to show you a little bit of a variation as I said on that stove so let's just talk about drawbacks of the typical one can or single can tomato juice can stove biggest one is that if you're really a fire rated in the bottom of this you run the risk of starting the forest on fire you know it can get a little bit of heat buildup here some combustion and depending on what this is sitting on you got to be really careful and I'll just show you something my last video I did a test of the Tong Shu rocket stove and a piece of wood that that was sitting on I showed it to you in the video but that's the burn mark that was left when I was done with that as you can see if that was out in the forest we'd probably have a bit of a situation on our hands we didn't have some water close by so a single wall stove or an open bottom stove that's the big hazard the other thing is that while a single wall tomato juice can't stove works pretty well it's not a true rocket stove and what are we talking about we're talking about a double wall stove that actually burns the the superheated gases at the top of the stove not that that doesn't burn well but you're not getting the maximum efficiency out of the fuel that you're putting in that so using my tongue she rocket stove is a little bit of an inspiration I thought can I come up with something better than this and on top of that let's make it really simple I don't want to be you know welding anything grinding cutting even drilling if you're in a situation where all you've got is some basic hand tools are you really gonna have a power drill so let's make it even simpler than a household drill simplest tool cheapest tool tool that everybody's got if you've got cans at home you've got a can opener and so that's what I'm talking about we're gonna make this stove with just a can opener a little bit of a trick to this can opener you see these all the time this one's got the little triangular wedge on the top of it other than that it's it's your regular can okay so I'm gonna make a double wall rocket stove that's gonna burn efficiently safely and we're gonna do it all with a two dollar can opener stay tuned so we're making a juice can stove here today first thing we need to do is talk about kin selection 48 ounce tomato juice can pineapple juice can same thing 48 ounces but the biggest can that you can get in your supermarket other than maybe a coffee can we're gonna go with this size and shape a can because it's fairly tall and narrow I'm gonna use the pineapple juice can have already got that one opened up here because this is a double wall stove we need a second can for the interior and essentially what we're talking about is a second can that's a little bit shorter still kind of tall and and narrow and a little bit smaller diameter so that this can fits inside that one with some some room to spare so those are the the two cans that I'm using this is a Puritans - you can if you use a tomato sauce can it's gonna work as well about 700 milliliters sorry guys I don't know what the fluid ounces is on that one but you can see if I just compare it to it chunky soup can it's the same diameter but it's just a little bit taller so let's go with an inner can that's as tall as we can get it fairly narrow that fits inside the juice can so I got the labels off my two cans I should just show you that I did cut the tops off both of these and when choosing a can opener you just talk about that a little bit make sure you choose a can opener that leaves this top lip on both of your cans some of the I think it's a starfrit one actually cuts that off we want to make sure and have that that top lip and cut off the inner part of the top so got labels off with my two cans let's go ahead and start poking some holes in these things and I'll show you how they go together so let's take the the outer can first this is the bigger one the pineapple juice or tomato juice can and we're gonna start by poking some holes into the bottom of this with the triangular portion of our can opener now I I found that i tested this a couple of different ways and it really doesn't matter how many holes you get into the bottom of this space them evenly but make sure you leave enough meat on there to preserve the integrity of the can and what I basically figured out is that I cut for first you know two diagonally from each other and then I cut another four just essentially splitting that difference I tried eight it worked a little bit better you know wasn't a whole lot better so if you've got start with your four any there's space with two in between which would give you 12 holes or you can go with eight let's let's start with the first four here and and we'll go from there so what you want to do is put your can opener at the bottom of the can and staying away from the scene that's gonna be the hardest part to punch punch into let's just go a little bit off of that and punch a hole into the bottom of that just go across from it that was my first hole I'm gonna go opposite punching another hole in the side of the can I think it's fairly easy to do literally just a matter of a couple of minutes there we go and so we got our our four four holes it's a fairly good gap here I'm gonna go with two I'm gonna split that difference so let's go twelve holes in this one give us a little bit more airflow and we're just gonna punch those those all the way in haven't got as much room between those two holes I've been yakking here instead of maybe watching exactly what I'm doing but I'm gonna split that difference there with two holes let's go two more holes there those are a little bit close together but you know what it's a cheap tomato juice can stove doesn't really matter so we've got holes punched around the bottom of this guy so next thing we're gonna do and I'll tell you why these holes are kind of important in the shape that they're in we could take a drill maybe it's some other stoves you just drill holes in the bottom of that but these triangles are actually going to be important when we put our inner can inside of this and I'll tell you what I'm talking about so right now these holes are flattened the points are flat and right out we want to make sure that we pull these points back up a little bit and see if I can demonstrate that I'm using my can opener okay so there's one that's punched all the way through and there's one that I've pulled back up a little bit we're gonna pull these points back up from the inside so that when we take the inner can and put it inside the other can it actually sets up sits up off the bottom of the can giving us our double wall on the bottom and by pulling the points of the triangles just back out a little bit with the tip of the can opener maybe there's another way that you figured out how to do that but I just reach in and grab the point of the cutout and just pull it back up a little bit I'm never gonna be able to see that not much maybe just a you know 3/8 of an inch less than a quarter of an inch but we're gonna go ahead and do that all the way around so that when we stick our can in it's gonna hold the bottom of the inner can off the bottom of the exterior can buy just that much okay so I got all those points pulled up a little bit I'll show you what I'm talking about by just putting dropping that inner can under there no I get that close enough you'll see that the inner can is not resting right on the bottom of the outer can it's just up a little bit and that's what we want we're still allowing the airflow but we're getting the hot surface off the bottom of this inner cam okay so let's set this aside and we'll go to the inner can so inner can similar we're gonna punch holes into the sidewall at the bottom of the inner cam I'm not going to punch holes into the bottom of this because I want this to be this combustion chamber to be solid on the bottom which is going to keep all of the hot coals and ash into the can and they're not going to drop through into the bottom of the exterior can so let's go ahead once again punch holes into the bottom of the inner cam I'm going to start out again with holes on the opposite side let's go with four no we can see that or not we got four holes let's once again if there's room punch a couple more holes in there you see my spacing there I'm just trying to go quickly for the video might have actually marked them out a little bit better that space is a little bit narrow there so I'm just gonna do one just one there again preserving the integrity of the bottom of the can and one there don't know exactly how many holes I've got but you can see the spacing these ones I've punched all the way in and flattened right out okay so let's go to the top of the can this one we're gonna do towards the outside we're gonna do another roll around the top of the count and I'll show you why we're going to do that in a second so from this side of the can if you can see that I'm gonna go out now you can see this this is left kind of a sharpie or sharp pointy thing out the side of there you know it's just gonna be way too dangerous I'm gonna tell you why that's gonna be important in just a second here so let's go ahead once again from the inside start with four and here's our four holes so that these are sticking out let's go ahead and and add some more once again if we've got room we'll split that difference if there isn't enough room we'll just do one hole not super critical again preserving the integrity of the top of the can as much as we can so we're gonna put as many holes in without that's actually damaging the rim of the can so now you'll see I've got all of these tabs all sticking out like that so now the reason that that's important and I've got those sticking out we've got these standoffs on the bottom so that when this can goes in it's not sitting right on the very bottom when we stick this can inside the other can we've got a standoff around the outside so the gap around the can is fairly consistent not super critical but it's those little tabs are centering the inner can in the outer can so now that we've got all our holes punched into this can the ones in the top row in the bottom so one more thing we need to do to get this stove to burn really well and that is punch some additional air holes into the side of the can so to do that I mentioned no special but you could use a drill or something like that but I used a basic kitchen steak knife nothing fancy just the neat cheapest knife out of the drawer because I never be poking holes into the tin can here so I'm gonna go ahead and do that actually before I do that I'll show you one that I've already done and hopefully you're gonna be able to see that three rows of holes spaced evenly apart just kind of offset gives us the perfect amount of airflow to maintain a good chimney effect so mostly smooth side and get us just enough air into the stove that that thing is gonna take right off so I've got my tin can I've got a cutting surface here I'll show you what I'm talking about really easy just basically holding the knife by the blade not the sharp side and giving it a poke and that's it fairly easy to do the core this is probably the most dangerous part of this whole operation so total disclaimer here be careful but easy to do goes quickly once again no special tools required so went around and did you can see see what the spacing is on those there we go I've got a couple of holes went around and spaced the first row like that offset the second one and the third row in line with the first row so I'm gonna go ahead and finish that off and then we'll get on with the next step okay so now that I've got that finished three rolls of poles with their knife let's go ahead and finish off the top of the exterior can okay so let's go ahead and finish up the top of our can now there's a couple of different options here and I'm gonna show both of them to you one is just a little bit more complicated than the other one and requires a little bit of extra cutting so I'll show both of them to you both very simple slight advantage and disadvantage to both of them so as you can see this is one that I've done previously this is the one that we just finished this one has triangles cut into the top of it this one is is unfinished this one here let's just talk about this one for a sec I've taken the same can opener and cut the triangle into the middle essentially giving us a pot stand off so if if we've got a smaller pot it'll actually sit into the onto the triangles there and not fall inside if we've got a larger pot let's look at I've got a coffee can here we've got a larger pot that can is gonna sir a pot is gonna sit on the top the the flames are gonna come out the holes and again that's gonna give us a standoff it's it's gonna burn very well it's not gonna be snuffed out and it's gonna be quite efficient so so that's the standoff that's built into the stove you can use it with a smaller cup or a larger pot and it's equally effective either way the disadvantage to this version of the stove is that when you want to feed the stove you have to take your your pot off the top so disadvantage pot comes off the top advantage there's no extra pot stand off require so that's that's the one version the other version I mean the gift to you is just maybe an extra step a little bit more complicated but that's using a pot standoff and by a standoff what I'm talking about is is one of these guys right here that you're gonna see on all kinds of propane stoves or my Tom Shu rocket stove has something similar and the way that works is that we're gonna leave the top of the can unfinished and we're gonna put our pot standoff on the top like that now one of the things that I like about this version of it a little bit more of a chimney effect here so we've got flames and draft coming right up to the very top of the can I think it improves the combustion just a little bit another benefit to it if I can use this as an example if you use a smaller cup you can actually feed your material past the standoff into the stove without having to remove your your cup or pot on the top even if you take a larger pot something like this to some extent you can get that over to the side and you can still feed smaller sticks anyways in in pass the pot so this one's got a pot stand off this one has basically a built-in stand off or some air holes in the top so the choice is yours this is done with the can opener this one I did with a basic tin snip so just your heard variety tin snips and a little bit of material that I had laying around the house so so that's what the standoff looks like a little bit of a notch there in a piece of metal notch in the center of the bottom the bottom of that one and notch in the top without one just allowing us to put those two together so I think I'm going to go ahead and do a separate video on the pot standoff this one's long enough already but we're gonna spark both of these things up and I'm going to show you a side-by-side comparison of how well they burn okay so let's go ahead and spark these two stoves up here and before I add a larger amount of wood I just wanted to show you something really quickly I've got a just a bit of a twig on on fire here and if you can put your your match down to the bottom of your stove like that you know that you've got a reasonable amount of airflow when you're making these if you're a fire source your match your twig a fire starter goes out when you put it to the bottom of the stove you know that you're gonna have to do something about air flow even before you start but you can see that has actually sparked up a little bit there's a bit of a draft happening already even with one little twig in there that's that's burning and this is really gonna make a difference when you're lighting your stove if you've got just a few pieces of dry tinder and kindling and you can get a stove or a fire going quickly and easily without any trouble you know that that that stoves gonna work out well for you now even though I'm just sort of randomly placing some kindling in there it's not even that small but it's sparking up very easily I'm starting out with the stove that I had already used and we'll get the other one going in in just a second here but just top feeding that adding some material and you'll see that that stove lights without any trouble we're kind of in a position on top of the stove that you can't see the flames coming up but they're already up to the top of the the wood there and if it gets any higher I just might have to move the camera so without any effort we got a good fire happening in an hour and our stove they're all ready I'm gonna move the camera out of the way so he don't burn that so I got that pot sitting right on the top of the center of that and the only air that the stove is getting is from the bottom those vent holes around the bottom and of course the ones that are just underneath the pot itself okay so I sparked up version two here this is the one with the pot stand off and I've just got a chunky soup cans full of water sitting on top of that but with very little material in there you can see that we get a really hot fire total combustion and virtually no smoke whatsoever okay so that one's perked up fairly quickly again with a little bit of fresh material but the disadvantage is is that we have to take the pot off the top version two here is still cranking right along and we can add fuel virtually at will there and we got some some bubbles happening and in our water they're a little bit steam coming off the top so that was just a matter of I don't think it's been more than five seven minutes here but both of these stoves continuing to burn quite well now the other thing I'll just show you here while I've got the this the the fires going in the stoves let's just take a look underneath both of these stoves and you'll remember in the Tom Shu video that I did fairly quickly in I move the stove over and you saw the amount of burn that was happening under there this stove here we've got just a little bit of discoloration there let's take a look at the other stove again very slight discoloration a little bit of warmth there warm to the touch a little bit of warmth there as well but so far quite manageable and you see the size of the the flames coming out the top of both of these stoves very little heat transferred to the surface that they're sitting on so there's a couple options for you on a double wall tomato juice can rocket stove you know I've had a lot of fun testing these things it's been an interesting learning experience to figure out what really makes these things burn well and what makes them tick and like I said it's been a lot of fun so I hope you guys enjoyed the video it's been a little bit of a longer one but I trust that there's some useful information there for you guys when you go to build your own tomato juice can rocket stove thanks for watching until next time take it easy
