- Here I make a propane gas forge out of a large #10 steel can, and homemade refractory lining and a new burner design.
See the newer forge build here! • How to build a trashca... - Věda a technologie
Tip! I built my own version of this exact burner & forge a few days ago. Afterwards when it dried I noticed the lining was getting soft & powdery after firing. I could scratch it off with my finger nail. So I created a hot saturated solution of LYE. I kept it on the stove on low heat (steaming, not boiling). Then used a plastic syringe to drop / coat / saturate the entire inner and outside lining with hot lye solution. It took about 2 hours to do and soaked in nice and deep. It needs to be hot otherwise it doesn't penetrate nice and deep. After I finished I decided to take a mini propane torch and heat a soft section of the lining that was breaking off before. Then when it cooled I touched it and it felt like a ROCK. Was hard as hell. So then I set off the forge with the wet lye all over the lining and THIS WORKS BEAUTIFULLY. First you'll see the steam come out (do not breath it in). Afterwards you can actually see the lye melt and immediately react with the silica in the perlite to make solid water glass. The whole lining changes aesthetically & structurally. You get hundreds of small, white popcorn looking beeds all over the lining but their all the same size and it looks awesome. After I fired it for 15 minutes I came back with a screw driver poking parts of the lining that were soft before and it was all ROCK HARD. I couldn't scratch off or break anything.
But here's the coolest part, the forge is getting WAY HOTTER now. Before only the bottom got yellow hot... after I did this the entire liner gets white hot and bright like the sun.
My guess is when you seal the liner like this heat is reflected like a mirror ... there's no pores in the liner for heat to dissipate or penetrate through. So the second heat hits the liner its reflected immediately back into the forge which makes it get insanely hot.
I'm not exaggerating one bit. Afterwards I stuck a stainless steel spoon in there, held it a few minutes with pliers, pulled it out and the entire top of the spoon was gone! Then I shut the forge off, looked inside and see the steel melted to the bottom of the liner.
So naturally I had to connect my MAPP gas. I tried it again and the entire base of the spoon melted too. So I shut the forge off then popped it off with a steel wire and it came out like a little pancake.
I have no idea how this thing is melting steel (I'll take pics if anyone wants to see) but I need to try larger amounts in a graphite crucible to see if I can melt and pour larger amounts. I'm also confused as hell about the difference between temperature vs heat energy? I've been reading on forums about this. Anyone knows you can put a thin steel wire in front of a 1000C small propane torch and that steel wire will melt. So when a forge is properly insulated and your pumping hundreds of thousands of BTUs in it.... what's happening? Is it because the metal is more thermally conductive than the silica? So when you're pumping heat into an insulated area... the heat keeps rising and rising then you throw steel in... that steel sinks the "heat energy" which causes the temp to rise then it melts?
That's the only thing I can assume is happening. And if I can melt a steel spoon that has to mean I can melt more steel in a crucible.

how do you make the lye solution?
lye is just NaOH, so just dissolve NaOH in distilled water.
if you mix wood ash with water you have lye
this will be a mix of KOH and NaOH, mostly Potassium hydroxide. Caustic Soda is generally NaOH and Lye is KOH. they are interchangeable terms for some people.
Your forge could actually be used in glassblowing to reheat the glass as you continue to create a vase etc. You are very intelligent& resourceful. I enjoyed your video!
Thank you for being alive and for taking the time to share your gifts with us.
Followed your sodium silicate vid and now this one which i made out of a new gallon paint can and fired it up......This is going to be a blessing over my brake drum forge.
Thanks for the great details
I love this video. your voice/attitude is like david wong from the movie john dies at the end. and you are accidentally doing asmr and no your not boring just relaxing.
Lol! Thanks! Some people don't like my voice.
Some ppl talk to much on their vids.
Yours, perfect clear and to the point. Very good how to vid, thumbs up
woahh that camera zoom was amazing
This was the most exciting thing I have ever seen in my 32 years of age, or 17,289,672 minutes or 1,037,380,327 seconds old. Keep me updated when you make coffee out of a forge.
I just did this with a paint can and it worked out well. I can't wait to learn more and keeping practicing.
Mind blow!!!!! I love it, i have perlite, i have a coffee can baby powder yes! I have THAT too! :-) i'm well on my way to making my very own forge! Thank you for sharing, i'm excited just thinking about it, boo yaa subscribed and liked
From a woman's point of view, I think you do a great job and don't let other people get to you. They wish they could do what you think to do!! Enjoy yourself and keep the videos coming! I know my husband and I really enjoy them. Good for you!
Roger StOnge Thank you! As far as people getting to me, it's not really bad on my channel, 99% of my viewers are awesome. Other bigger channels have much worse to deal with.
Very interesting and informative. When the forge I just made gets worn out, I'll have to make one like this. Never thought of using perlite
Does anybody see a problem in using this method of making a forge , but using a much larger container like a “35 gallon “ propane tank from a forklift (about 30” long, and about 15” in diameter), and make it with a 4” cavity.
Out of all the mixes I have watched on Ytube....... this seems to be by far the easiest to deal with and get the best results.
Thank you for sharing.
+RTOHIO It was part of a 3/8 fitting I sliced off for another project, then filed the flats off of it. A 3/8 to 1/2 face bushing also works. I did not know there were that many people wanting to build this exact burner haha, Designing your own is fun and rewarding. Thanks for the comment!
I have like no knowledge base in this subject. Are there perhaps things that you read to learn about things such as this that you could tell me about?
It wont hold the heat in nearly as well, but it would be more durable, sort of. After getting good and hot the concrete will crumble.
Adrien Perié I had no idea tin can smelters/forges were only thought up by one other person. Shit I'm glad I didn't make my own and steal their idea =O
***** lmao that's funny. I thought the same thing.
***** The guy made an EXACT copy of NightHawkInLight's soup can forge, re posted and is giving absolutely no credit on this video thanks to which he is making a wad of cash. That's just pathetic and lame.
What are you doing today? Oh, you know. Just frosting my forge.
Really nice burner nozzle you designed! I'll be making one of these soon and appreciate the build!
WOW! This is well thought out. I saw your video on making sodium silicate. You are so helpful by sharing your sources of all the products used. thanks.
Thank you!
6:54 that's one hell of a camera.
Where did you get the valve for the disposable propane bottle or did you make that one? if you made it can you tell me the components I need to make one. Thank you
I would love to see/hear about that valve too.
same, I would really like to know because most people just use blowtorches but if you actually could let us know about the valve i think that would be more convenient.
Good job! You look like you know what you're doing. I look forward to more. Explaining some of the reasons for doing your build would help. Keep up the good work!
Awesome video for your build! Love the way you did the project! Thanks for sharing!!!
Christ! If that hacksaw slipped... !
Cade Howell, sorry your comment dose not have a "reply" botton, so I can't reply to it directly, my plan is to use it for heat treating.
+clkindred what you put in the solution for accelerating the process? i dont understand, im spanish so it sounds like plaster or blaster
+Tomas Giavarini Dijo plaster of Paris, o sea yeso Paris o yeso común para paredes.
+clkindred Hi you can add a plus sign before the name to direct comments to a person eg +Cade Howell
On the topic of your video and forge I noticed you use Perlite fused with Silica for the insulating wall, Would having a thermal retaining material inside the forge wall be more effective in retaining and increasing the temperature?
I would also consider applying a fan of some sort and vents to initiate a vortex inside the chamber.
Similar to a fan forced oven. not sure how to describe it in words but can visualize it...there is more fire/heat passing over a given point.
I collect all these ideas for nothing, to pass them on I guess to people who can apply them.
clkindred . mnnn
clkindred m.l...
Thanks for the breakdown of burner building. Very nice.
You're welcome, and thank you!
Wow...that is awesome...this is the best forge I have seen by far on CZcams. ....really quite impressive...and done with items you might and most likely have lying around at home
how much would you sell one of these for if i wanted to buy one from you rather than make it myself?
How much you got$? I would male one with steel pipe instead of aluminum .
useless knowledge I’d pay $40 shipped
that gives me an idea of how to take an UNinsulated safe and INSULATE IT!!!! I figure if your fire wont get out, then a house fire wont get in. THANKS!!
Dude wicked idea
The use of Perlite and liquid glass is pure genius.
Thank you, I have all the parts now! I'm going to build the trash can version with my boys. I also picked up a decent size kiln which I hope to make into a foundry. Thanks for the inspiration and instructions!
Cool! Have fun and be safe!
I've always wondered how plumbusses were made.
Underrated comment
Does it need to be Folgers, or can I use the cheaper Butternut can?
as long as it's a metal can, it will be fine.
+clkindred why cant the steel be galvanized? hazardous oxide gasses?
Zinc gases from the galvanization process get released, it can cause metal fume fever.
I've gotten it from welding, it's not lethal(Usually), but it's the worst headache of your life.
once the zinc is burned off it won't continue to make zinc oxide fumes. need 1600+ degrees to make zinc oxide fumes and in don't think the can itself is getting that hot. use in a ventilated area like you would want to regardless. it's fine.
Dude, that was freaking awesome. Thanks for the tutorial, I’m looking forward to making myself one. Keep up the good works!
AWESOME VIDEO! This is definitely my next project for my shop! I make custom knives and this is way handier than having to fire up my large forge to forge smaller bush craft knives.
Pretty soon all these mom and pop stores with special crafts will be obsolete. CZcams is gonna help everyone do it yourself. I seen a news article about a mother and 4 children building an entire house with 8 bedrooms and brick exterior by using CZcams how to videos. 😆😆
i hope so ..then wee will get rid of walmart ,amazon (and monsanto )and other monsters ruining our purpose of life .
do it yourself is bringing back happy life which is missing lately duo to to much shit goin on
PRANKurFACE holy shit your totally right haha it's good though everyone will have extra bonus sets of skills
@@stanjarmolowicz most people are too lazy and would just rather buy things!
please build more and sell them on EBay.
I'd buy one for sure😉♿️🇺🇸
you are a genius ... it make so easy ,inexpensive and can be done after morning coffeee before noon !!
Thank you so much for sharing the idea ...i'll start it right away by getting components today .
How can you not like this? It's freaking cool!
Melt down some lead and dump it down a big ant hill, wait a min😏
Then dig it up 😐
Looks like a lead piece of coral ☺
PS. If it's a really big ant hill
Prepare to dig, and a good bit is needed for it to look good
You know what would look really cool? If some giant came by and poured molten aluminum into the chimney of your house until it was all filled up. With you inside.
Then stripped all house away and showed his giant friends how cool a little person's house looks cast in molten metal. And there you are, a teensy skeleton trapped in your tiny living room for all time.
@@adamschaeffer4057 lol, I hate to say it but that would actually be pretty damn cool to see. A completely horrible and unethical thing to happen in reality but in the form of a short film on morality a fascinating spectacle to behold and comparison to contemplate.
Even from a filmographic technical perspective: creating a house that could attempt to even temporarily withstand the weight and temperature of the molten metal and then some kind of super helicopter that can carry lift and pour a giant crucible of molten material into a chimney could be a documentary of its own.
Lol, If I ever meet a producer with money to burn Ill pitch it, thanking you!
@@nicoleyensen7062 Tell them to cast Tommy Lee Jones and Ann Heche. Call it Reverse Volcano. I'll look for it in 2022
I have no idea why Im watching this video...
+Art Mehmeti because its cool?
+So1othurn I can assure you its quite warm
+Art Mehmeti I will second that, well Art I guess we can go into the home made knife business, If you happen to live out west we got the market covered. LOL I live in Pa.
+mick jagger I do as well so if you make knives let me know
Rafael Roman well I have made knifes in the past & now im in the process of acquiring the tools/gear to start making them again. I have been getting requests for quite a few hunting knifes. I have a lot of hunters in my area. (Mt. Pocono, Pa.) The home forged knifes are just unbeatable. they hold an edge for a long time. & are very EZ to sharpen & hone. I will keep you posted. Going to start asap.
Try setting you burner at a 40 degree angle. Heat will circulate inside a bit better, and can raise the temps some. Thanks for the videos, I found one that will allow me to finish an on going project.
Great tutorial with few amount of words and no annoying music. Keep that up.
If anyone is having a hard time finding the Apple Corer.
These are virtual identical as far as the stainless tube is concerned.
Norpro Apple Corer - Model #: 5103 - www.amazon.com/dp/B004L04PV0/
Fox Run Apple Corer - Model #: 5547 - www.amazon.com/dp/B001BHHN0G/
I was really hoping the directions would be:
1. Cut coffee can.
2. light on fire.
3. stare at fiery death machine.
Excellent do-it-yourself video. You are very resourceful in your construction - outstanding!
Metal recyclers also have materials they sell by the pound. If a coffee can is worrisome you can find heavier bits at the recyclers. If you live near the coast where ships are built you can find exactly what you want often in stainless. Loiusiana near the oil rigs should provide any size you can imagine.
hmmmm 911 dislikes.....
COFFEE CAN FORGES CAN'T MELT STEEL BEAMS!!!!!
Smatchimo Lol.
Lmao
But they can weaken it till the point of failure like we saw that day. Best smackdown video ever: czcams.com/video/FzF1KySHmUA/video.html
Thermite says what?
How long will a tank that size release propane at degrees needed?
i made one of these but it melted, maybe i should have used a metal can instead of plastic.
Hey. You just blow in from stupid town?
Lol
Rumpleman456 II,k,''',on their first
I hope your jokin!
Hmm I don’t why it melted strange
Thanks this idea is going to save me a lot of money, I saw the soupcan one but yours is bigger and will be of more use to me. Thanks again for upload xx
Thanks for making this video, it helped firm up my understanding of gas burners.
I'll have to try making an arrayed burner for a large propane forge.
Thanks, and good luck!
Do you guys know what the full ramifications of heating this stuff up and breathing the fumes, I am sure there is a good scientific reason why the industrial community is NOT making these on a regular basis. Sure would be nice to have one of these on my worksites across america.
i love all this stuff .........but , some of the melting ,smelting,welding ,milling & plating stuff ive seen horrifies me .....hahaha ......still .................................................................its your health guys
No Mike I dont, but you make a very valid point. What are the risks and what are people breathing in? Credit to you for pointing this out....even more credit for explaining what type of gas mask filter people need to wear.
Is this organic or non organic fumes, and will a P90 mask filter out the particulates?
Thanks once again for your input
just do these things in a well ventilated area. :)
Im about to make one based on this design, and in the last few weeks Ive learned a bit more. They are probably not made by industry because for a less than a grand you can buy an electronic kiln. For a business that is cheap compared to a law suit based on an improvised piece of kit. (thats my personal opinion btw). The other is that if you used these on an industrial scale, apparently sand/plaster mix whilst great for the hobbyist, has poor refractory values, and after some use it will start to disintegrate and require re-lining again.
As far as health goes, Dank Pepto has the right idea: Use this, and in fact do ALL high temperature work, in a well ventilated area. Also, when it comes to doing anything to do with high temps, or grinding/sanding where you create dust, were a simple half-mask respirator (those pink/purple ones you see in all the knife videos). I think they are 3m multigas filters with a built in P99 dust filter).They are basically the civilian version of a CBRN filter. They will bind active organics and filter out particles. Just remember the filters dont last forever.
The only big no-no, is watch out for anything chromed, that gets burned. Apparently those fumes are very unhealthy. Burning or super heating chromed metal parts will cause them to develop a yellowish crust and give off fumes. Not good. I read its best to turn off the chrome finish. Not sure they will get hot enough with this design though.
Sorry for the wall of text, the short version is:
Assume everything to do with welding, sanding and forging is toxic
Do it in a well ventilated area
Get a cheap half mask with pink filters from amazon
Wear eye protection.
Good luck chaps.
You make a valid point. My first attempt at smelting metal, I'm pretty sure I gave myself metal fume poisoning. Instant hardcore flu. Be careful and make sure it's in a well ventilated area.
my only question is...who drinks Pepsi Max?
+Bobby Jones You are not the only one who can't wrap their head around that haha.
Mormons
People that like Pepsi but need a little more kick. I guess. I've never heard of it believe it or not.
Me
Thank you. Great process and workmanship. Bravo
The apple corer as a burner is pure genius!
cement could used just as easy.. and cheaper..
Not as insulating..
Cement will pop and crack with heat
since when? XD dumb ass
Jerrod Vaughan apparently youve never used a torch by concrete lol dipshit
Lelouch Vi Britannia apparently you didnt read what he said first
how did i get here? from porn???
Lol
I have absolutley no reason to have one of these yet I still watched it all....good stuff.
Awesome project! Thank you for sharing. Sure beats paying out over a hundred dollars to a few hundred for a factory made one! We all gotta keep remembering that we CAN do amazing things for a low price like this... to never forget the old presidential saying, "do what you can with what you got!"
great video, thank you for adding "all" needed information !!
That was very informative. Nice work!
Nice job. You've produced a simple cheap forge that anyone can make. Good vid too and very well explained, thank you.
Thank you!
Thanks for the advice and taking the time to read my tex.its just a dream off mine to make this oven iv been toying with the idea for about 3 or 4 years now I hope that one day I will get around to doing this as I do love experimenting plus I do love pizza too lol all the best and have a great day
haribo stinky Thanks!
Thank you! I don't know what I would do with one, but I enjoy this sort of thing a lot! Nerds of the World Unite!
that burner is sweet
This is an incredibly well made video!
You sir, are a boss!
Albert Pike Thank you!
I used perlite and furnace clay from the hardware store. Worked great for years.
Thank you great video Exactly what I have been looking for.
this is the first vid i have seen of yours. i love you already! you rock!! thank you for share sir!!!!!!!
I am building this bad boy baby forge even as we talk!!!!. It's gonna b alright,outta site, dyno-mite, and it " ain't gonna bite"!!!!!!!!
nice video made almost the same thing about 10 years ago lots of fun !!!!!
that was so cool and I will try to do the same thing with an old oxygen gas bottle.
Really nice video, very easy to understand too, thank you!
I thought this video was amazing. Even if it might take some cautious experimentation to use the notion for hobby purposes, thank you for the ideas. :)
That 1st zoom was badass
Very cool !
Great idea !
nice job mate, very inventive.
I liked watching how you made the burner, the new tube design of what seems to be a large scale of a soldering torch tube. I'm soon going to make one and make a foundry like yours in this video but a bit larger so I can melt larger pieces of metal just to compact the size. I will use free fuels to burn them, either reclaimed fossil fuels, used motor oils and old fuels mixed using them to extract vapors that will burn not using them as solid fuels if I can make my design work it will make the fuels last so much longer and will be free.
Pastor William Barhorst Have you seen this design? czcams.com/video/P-A8uoWdBB8I/video.htmlt uses liquid oils but still might be worth looking at. The vapor design like old gasoline blowtorch use would be an interesting build though, with a lot of design challenges. Like how to keep non vaporizing contaminants from gumming up the system.
Good information, I'm thinking of building a slightly larger furnace for melting aluminum. Will probably use castable refractory as suggested in Dave Gingery book "Lil' Bertha"
Great job! Well thought out. I enjoyed watching.
very very nice.simple to do and seem to be efficient !
Wow, this is pretty cool concept! Before I came across your video while I was in the works of making my own coffee can forge. Accept my insulation is Portland cement and crushed up firebrick, and I'm opting for less insulation for more work space for my blacksmithing. But instead of one propane torch, I'll have two torches pointed down in a "V" configuration on to my steel. I might coat the out side with some fire cement as well. But the way you went with this one was pretty ingenious!
Thank you so much! I'm working on a different design for my next forge, I'll post a video when I'm done. You're right though, this one is slim on the work area, part of the reason I made the new one is this was too small. I am interested in your insulation though, I experimented with portland cement but did not get very good results. Please keep us here updated on how it turns out! Thanks again.
clkindred Sorry for the delay clkindred! I have been rather busy lately, and haven't had the time to reply back or work on my forge. But I got some more stuff for it and right now I have different batches of the Portland cement and crushed up firebrick curing to see what is a good mixture to use. I will make sure to keep you updated on how things are going, it might be a while though. I also got some fixins to make some water glass thanks to your helpful videos! I hope to make a little bit bigger foundry than what you did but ...... that's still a far bit off for now. I can't wait to see what else you have in the works!!!
Top build, freaking awesome.
I don't know how I got here and I have to wake up for work soon... This is really rather cool though. Been trying to figure out what materials could be used to insulate a small furnace to melt down scrap aluminium and this looks like it might do the job!
Would be interested to know the difference between this and a 1 Portland cement/ 5 Perlite mix
this is very cool im definitely making one of these
This is pretty neat
Thanks for sharing your knowledge.
...Like the way u working... Awesome vids, thanks alot
yeah this is super helpful for me... thank you very much mate. Really appreciate the video, and all the tips along the way. +1
Wow this is so cool, thanks for posting!
Moors Hound Thanks for watching!
This sounds Dangerous, But my curiosity wont let me stop watching!
As far as I know, you're the first on CZcams to use these chemicals. If this works for an extended period, you will be a hero of sorts, because the system has us all believing that "refractory" material is 4th in the Trinity; as in importance and price.
This is an exceptionally good video.
thanks! Yea all the commercial refractories are all proprietary and they are not very forthcoming as to what is in it, might bite them in the ass though, if someone invents something better because the store bought stuff was so expensive haha.
Thanks for video, I made this but couldn't get my inner can out after the. Plaster set (half sand half plaster). No problem though. I use mine upright full of charcoal and a hair dryer instead of gas burner in the feed pipe , takes 5mins to heat treat a knife to temp. Brilliant. Thanks
+Ken Murray Charcoal seems to be a surefire way to forging heat, gas can struggle sometimes.
Great video!,Thanks for sharing!
Nice recipe. Thanks for sharing.
Nice work
I recommend using a mixture of plaster of paris and sand, 1:1 ratio mixed with a bit of water so you can use it as cement
clever build
Very cool great job.
Very nice video instruction.
Nice job
Love how you made it . But if you use a torch head called a rose bud and oxygen acetylene well burn hotter and faster for you ! And if you use the rose bud and a good handle you get more control of you flame. But bravo for making on from scratch !
