What's up guys welcome back thanks for . joining us today on the king of random . in the past we've shown you how to make . your very own backyard foundry using a . metal bucket and this stuff called kayo. wool well this has worked out great . we've used it for a whole bunch of . different projects and today we're going . to try and upgrade and build ourselves a . larger foundry using this bigger 31 . gallon trash can the basic principle is . that we have our metal trash can which . will contain the heat nicely but it's . very conductive and would easily let the . heat escape out into the air so we have . this stuff called pelo wool which is a . very good insulator holds the heat in . extremely well in fact you can put a . blowtorch on one side of this and your . hand on the other side won't even feel . it i don't think it's even warm after . that so that's the plane will line the . whole can with the kol that way we'll . have the metal container which contains . everything and the koat wolf will hold . in the heat now that we know we're gonna. do let's get started a quick note about . the kayo wool it's a fiber e substance a . lot like fiberglass so it's very . irritating if it gets on your skin or . especially if you breathe it in so i'm . going to be wearing a dust mask and . that's why i have this long-sleeve shirt . so it doesn't make my arms all itchy . there we go hopefully that'll keep me . from breathing in too many fibers as a . first step i want to add a lining at the . bottom of our trash can i'm going to set . the trashcan on top of the cable and . then trace around that i'll cut that . circle out and that will go in the . bottom of our can . all right we've got our circle cut out . now we're just gonna push that down into . the bottom of our trash can now the ko . wall is at the bottom of our trash can . and that will insulate really well but . it's not very stable surface if we want . to rest up on it here we've got some . compressed ceramic fiber board that will . work as a stable base it's a type of . board that insulates really well and . since it's rigid it should be better for . standing things on than just the k award . [music]. now i probably want to cut this just a . little bit inside of wearing mark . because the very bottom of the trash can . is just the tiniest bit wider than the . inside bottom of the trash can i suspect . so we'll have a little bit of play maybe . if i cut it too small but that'll still . be better than having to be too big and . not fitting . [music]. alright there's a circle that looks . pretty good let's see if that fits in . the bottom of our can ah it's beautiful . there we go a nice flat surface that'll . be much nicer and trying to balance . stuff on unstable kayo wool alright now . i'll try and take our cable and line the . entire inside of it to figure out how . much of this cable i'm going to need . them just gonna put the whole roll down . in the can and then i'll unroll it onto . the sides as much as i can and then mark . where i want to cut it sort of start . with it inside there get a nice and . pressed up against the sides of course . the trash can is not a perfect cylinder . so it is a little bit wider at the top . and the bottom i'm gonna try and account . for that alright i'm gonna take my . marker and mark i'm gonna give myself . some extra that i can later trim off as . i do fine-tuning without all the weight . of the extra cable getting in my way . nothing's the trashcan is like i said . very slightly tapered ideally rko will . would have a slight arc to it to fit . perfectly around the edge we're just . going to fake it a little bit by cutting . one sided a bit of an angle and i think . we'll get a pretty good fit so i did the . rough cut before now i'm going to see i . can get that a little bit more refined . you can see that the edges are . overlapping by quite a bit at this point . this is where one side is so i'm going . to mark that right there and the other . one is right here and once again i am . going to give myself a little bit extra . because it's better for it to overlap . some than for there to be gaps . right see how we did it is overlapping . just a little bit which like i said it's . not a problem just take some squishing . and persuasion. there we go that's looking pretty good . right there the main body of the can is . lined so now let's quickly cut out a . piece the right size and shape for our . lid wonder if a knife would be easier . than scissors so i'm just gonna try that . and see if i like it any better as you . can see i am leaving an inch wide gap . that's the same thing that we did with . our smaller foundry this way when we . push it into the lid it will have a . little bit of pressure on it and help . hold it in place there we go . hmm i don't think it's gonna compress . enough with that extra border i left on . it this lid has an interesting shape to . it there's a lip that extends off of the . edge i think by adding an additional . inch to what was already added by the . lip my cable is now too wide to fit . inside the inner area of this circle so . i'm gonna cut it down just to where i . measured it with the marker and see if . it fits any better . all right now we've got our slightly . smaller circle let's see if that fits. into our lid any better . oh yeah that's exactly what you want. being pushed in a little bit it's not so . tight that it won't fit but it's big . enough that it's still got some pressure . holding it in hey . that's what we're hoping for and let's . give it a try throwing it on our hand . beautiful that should be one insulated . trashcan at this point now we've got the . walls and the lid covered in our . insulating cable and for now it's. holding himself on really well but with . our mini foundry overtime as it got . heated up and cooled down and heat it up. and cooled down time after time the kayo . wool lost some of its rigidity and began . to slump a little bit so i've got some. hardware and i'm gonna use that to . attach the wool to both the lid and the . sides of the trashcan a little bit so . that down the road we don't run into . that problem . the machine screw that i'm using here is . a little longer than i need so i might . end up replacing it later that should . hold it up pretty nicely now i'm going . to do the same thing at three points on . the lid. [music]. now no matter how much structural . integrity this ko loses it should hold . itself on pretty well it's attached now . we've got a very well insulated trashcan . but no way to add heat so let's drill . some holes into the sides and the lid so . we have a place for the propane heat to . go in and for some ventilation to go out . i'm gonna try and make the holes in our . large foundry at the same height off the . ground as the holes under mini foundry . that way the wooden blocks that we use . to support the burners will work at the . same height plus if we have anything . that's just on the bottom of our foundry . we'll know that it's getting the heat . that it needs . well that's smooth turns out a hole saw. is not the very best tool for cutting . through very thin steel but it's what . i've got so let's try it on the other . side . that actually almost won smooth all . right just as an experiment to see if . you try and use a hole saw on kol what . happens. [music]. still not perfectly but much better with . those holes added i think our full size . backyard foundry is ready to test with . heat now i do have a concern that the . spacing of the hose with these was . designed with the mini foundry in mind . and i'm not positive they'll stretch out . far enough to really angle the way we . want them to on the large trash can . we'll see what we can do . you might be alright alright i did get . both of them in and slightly angled but . as you can see the hose is being pulled . really tight and i don't think it's . gonna cause any problems for our test . but we'll probably want to add a little . bit extra hose before we use this . foundry for any extended amount of . burning. whoo that gets toasty quick you can see . that the burners aren't angled quite as . much as it should be that's partly . because our hose isn't long enough so . while it is heating it up pretty well . it's not really circling around quite as . much as we like it to let's so the lid . on and let this thing get really warm . [music]. turned off i'm just gonna see oh ah that . is toasty in there like the fire is not . going but it still just really really . warm inside there there you go that is . how to make a large-scale backyard . foundry there are a few different things . we're thinking of trying with this . foundry it's obviously much larger than . our normal backyard foundry which is. gonna let us do a few more things with . it we'll be able to fit a large crucible . and we also might try firing some . ceramics in this forge i also took some . of our leftover cable and i realign the . mini furnace and i was impressed at how . easy it is to do that it only took me a . couple minutes to completely replace the . lining this is a great little furnace. you can build and use and if the kale . will get so old that's falling apart . it's very easier place in just a few . minutes i'm really looking forward to . trying out some experiments with our . large foundry to see what it can really . do thanks for joining us for this . project and we'll see you in the next . one talk to you then seems like a . captain america shield and this one's . like a captain cotton shield not a very . good shield. hey guys i hope you're having a great . day you are awesome you are appreciated . and i know everyone over here on my team . is really grateful for you . thanks so much for choosing to watch and . support our videos we'll see you in the . next one. .
