I did your build. I did allow it to dry about 2 weeks before adding heat. After many melts, it's still going. CU, AL, brass, etc. However, it did get me hooked so I built a new one. 3K wool, 3K refractory and used a large propane tank. Hinged lid, etc. It runs on waste oil :) Now melting brass is way faster ha. Thanks for the addiction!
3K. 3000deg. Yeah, Ill do a video once it's all done. It's working great, but cosmetically, I'm making it into something ;) For now I can post pics on a webpage or something.
I've watched and personally witnessed the use of home foundries. The King of Random puts the key concerns into a well photographed and edited fun version of doing what so many enthusiasts have been putting off. Thank you TKofR, Jon
You Sir, have mixed the 11 spices to make the ultimate video! As a newbie, I learned more in 9 minutes than watching "foundry" videos over the last 10 years!
I spent a summer interning at a company that did lost wax casting as a side enterprise, and a couple of things they did would probably help. For one, rather than packing sand like this (since they were a production operation), they used a slurry mix to set each part bundle into its own dedicated mold. I think it was a silica type of sand, able to stand up to molten steel, and they dipped a few times and let each layer dry like making a candle. Another thing they did was heat each mold up to just shy of the melting point of the steel (medium carbon steel) so the metal flowed freely. And they were able to cast some exceptionally fine parts. It also seems like you could use some type of vibration source when pouring your sand to get it to settle and create a cleaner mold. If you do reloading you could probably use a vibratory tumbler.
You have such an amazing voice. I have no clue what you're talking about but I love listening to you. I can listen to you talk about anything for years and I won't get bored. Lool I'm weird. 😜
For years I have wanted a back yard foundry, my wife is against it from the beginning. Now that I have seen your channel I see a way around her complaints. This will be easy, and she'll have no way to complain.... Thanks, I will be watching a lot more.
Truly one of the best videos on the use of a home foundry I have ever seen! An outstanding job! Packed full of useable information, not fluff. Outstanding. Thank you.
Also, if you're REALLY focused on how high quality your castings come out don't use aluminum cans for your metal. Go to a junk yard, and buy up some aluminum intakes, alternators, or really any other engine parts that are aluminum. Those are made from a special alloy that has a nice tight crystal structure and will always look (and cast) better than extruded aluminum.
Squat251 Gaming it is is not as easily accessible also u don't need that u can always make the alloys because they do not require rare material, that is why they are in the junk yard.
Yeah, but at that point, why melt down existent aluminum parts at all? The entire benefit of cans is that they're, for many, free. A lot of the problems with them can even be resolved by ensuring they're fully dry and crushing them prior to melting, which, honestly, is something many people do already to fit more cans into the same space.
Dude this may be the most well informed well thought out and researched youtube video ever. Not because the content was cool or anything.. just the execution of the video. There should be an award for least useless video on youtube.
man mentioning others work in your own video?? what a humble person you are .. not to forget about your ideas that helps A LOT ... thank you for sharing them too keep it up KING .. I'm subscribing blindly XD
I have made this and I had a sort of a meltdown. The foundrie was extra big and I used a shop vac instead of a hairdryer. I melted a steel crucible and about a pound of aluminum and instead of stopping, I fired it up more and i melted it into the charcoal. I also tried mixing in even materials to "spice it up" and I got this crazy looking piece that looks like it's a meteor and it weighs a ton. I love your channel and this was a very fun build you should try to make a lid for the foundry so you can forge steel that would be super cool.
Dear Mr Grant Thompson, I had try make a little furnace as you shown at the tutorial video, and make a little modification by using 12volt ~ 24volt blower fan. The normal wind stream (not as hot as hair dryer wind stream blows) could be controlled by switching the potentiometer up or down to suitable electricpower as you need. Thanks a lot, sir...you were inspired me.
Along with the basic brilliance of your concepts, YOU ARE A GREAT VIDEO PRODUCER!! You talk clearly, fast and it's all relevant. You Edit and I know that is not simple to do correctly. You should be on educational television. You are better than most of those shows.
I tried this out at home and there's a couple things that I found out for myself that might be useful for you guys: 1) The 2.5 quater bucket hole size for the furnace for me was way too small. I could barely fit any coal in there along with the crucible and it took really long to heat up (+30 minutes). What little coal I could fit was competely spent by the time I got to melting temp. I'd recommend using a bigger bucket for the hole size, maybe one of those Neopolitan plastic ice cream buckets you'd buy at the grocery store. 2) The lid works fine, but the turbulence from the hairdryer launches ember through the hole of the lid and right into the crucible, creating tons of dross in your aluminum. I'd recommend adding grooves around the border of the lid's hole to protect the crucible's opening and make sure contents of the aluminum is as clean as possible. 3) You might be better off not using steel wool to hold all the plaster together. I find that the wool takes up a lot of room and it's really difficult for your mixture to actually mix in with the wool so your walls end up being pretty thin and brittle. Plaster and sand is not meant to last long anyways. 4) The plaster and sand mixture really does harden fast. Make sure you get your shape within the first 5 minutes of mixing. 5) I was smelting large aluminum pieces that could only be introduced to the heat of the crucible inches at a time, I needed to break the brittle sections that are halfway in the crucible, so I got a stainless steel rod and oven gloves to play with the aluminum as it heated.
Finally got all the materials to make this. Visited Home Depot and Ace Hardware and utilized some of his Amazon suggestions. If you only get the components for the Foundry(buckets, plaster, sand, crucible, u-bolts, and air pipes) it costs around $94 total. If you don't have hole saws, or tongs, etc it can be up around $135 which is still amazing for such a viable backyard foundry. I went a little extra on amazon, got me some nice tongs, a slag ladle, etc. Combined I spent about $150. Saved about $12 at Home Depot though as they offer a Military Discount again finally. Update - So I made this today(day after buying everything) and used the exact measurements for sand/plasterparis/water and it took well over 40 minutes before it began to solidify. I'm assuming it's due to me being in Florida with a higher humidity, however it did end up firming up quite nicely and holding the center bucket. Took about an hour and 20 minutes to cure. After removing the bucket(slid out easily) it turned out quite nice. The vent-hold was easy to cut, though I cut mine slightly lower, using the second line down and it came out about the same distance up. This entire process was so easy, curing time was really the only thing that wasn't nearly instant with this project.
I work in a Foundry. To get better casting you have to make mold veins for liquid metal to travel down then cut them off afterward. casting metal usually uses wax for a mold. then 2 kinds of sand ( slurry) one to stick to the wax and one to build up on the first to strengthen the mold.
I've been looking to get into metalworking myself, and had quite a few questions about what sand to use, how to build the Kiln, ETC, and be honest, this video has answered virtually all my questions. Thank you so much for posting it, and I will be watching the rest of your videos on how to make it, and how to make it work right. :-) have a lovely day. :-)
Assuming you're not being facetious. I had already made mine. I was one of the many people asking where to get a fire extinguisher. I found a place a few towns over that recycled fire extinguishers and had HUNDREDS just sitting in a warehouse. He invited me to come down an take what I wanted so I was very lucky and picked up a dozen extinguishers (anticipating failures eventually) for nothing. My biggest problem was that the extinguishers I found where wider than Grant's so I actually had to saw off about a half inch around the inside of my foundry to have an opening big enough to fit charcoal around all sides of my foundry.
I really like it. Not only is it very practical both for the hobbyist and the small businessman, the coolness factor for it being economical makes it even better
Thank you so much grant. After seeing your video the next day I tried and to create my own forge and was able to melt pewter as my first metal ever melted
Although this is an awesome idea, people need to be aware that this is extremely dangerous. My coworker had a piece of metal (that had an air bubble in it) explode on him and he was lucky to only have his leg and foot hit by the molten metal. It immediately burned through his shoes and gloves and caused such horrible burns that the doctors had to give him skin grafts and were very close to amputating his leg. It looked awful and he said he was in excruciating pain for about a week. If you are a beginner and are thinking of making this, BE CAREFUL.
My friend's dad is a full time blacksmith, and he gives all of this the highest level of approval! This sort of thing makes him really happy, because it gives people an affordable way to get into this sort of thing without having to commit their entire wallet to it.
Those little metal muffins.. I... I won't lie I... kinda wanna try to eat it... Is just looks like a little cake wrapped in tinfoil.. I can't help it..
Most interesting follow up, well beyond what I expected or hoped for, but that's how you roll! Thank you, sir, again for well thought out interesting and informative content.
Okay, some words of caution are necessary here: 1) Anyone determined to melt aluminum drink cans should be mindful that they have proper masks for filtering fumes and are in a very well-ventilated area (outdoors is best), because the cans are coated with vinyl to prevent corrosion, which when burnt produces carcinogenic gases. 2) Make sure that any fire extinguishers you are going to use as crucibles are completely empty, because sawing through a pressurized container=Explosion hazard. That aside, this is a neat idea for a lower cost foundry, I might have to try this model sometime.
the metal would be flexible under the heat of the burning fuel, and the weight of the building pushing down on it would cause the building to collapse. so in this case, jetfuel melts steel beams
The only melting steel FEMA talks about is insipient melting in some of the steel found at the WTC. Insipient means the beginning of melting. The insipient melting was due to sulfur contaminating the steel which caused corrosion, and would reduce the melting point in the areas of contamination (sulfur reduces the melting point of steel). So when it was subject to fire the steel almost melted in those affected patches. The steel definitely did not turn to liquid. No one knows where the sulfur came from, nor whether it occurred during or before the events of 9/11. That is the only remaining mystery of those events as far as I'm concerned.
One material I'm probably going to try when the weather gets a little warmer here. There is an old trick where you can carve a foundry from a loaf of stale bread then thoroughly char it over a grill. This creates a carbon foam. The problem with that foam is that it's not very dense and crumbles easily. However the density of the foam is proportional to the density of the bread. So my line of thinking is to set up a pipe inside the bucket the size of the cavity you want. Pack bread down into the section that will become the insulated wall as tightly as you can. Bake it over a fire until the bread is thoroughly charred into carbon foam and when it cools remove the pipe used to form the cavity.
I tried to melt aluminum cans using your mini forge, a couple years ago,with no real success. Thanks to this updated video, I'm going to try again, and I'm going to keep at it until I get it right! Thanks, King of Random!
I made muffins that seemingly welded themselves to my muffin pan. Not sure what I did wrong LOL. Wound up using the lower portion of a small blue propane canister that you'd use on a torch or lantern. Worked great the first 2 times I fired my foundry, then the third time, my hair dryer began spooling very high. Pulled out the air tube and out came 40 cans worth of aluminum. I'm not going to give up.
It's possible your temperature was too high and you did actually weld the ally to the pan. What were you using for a flux? I'm pretty sure if you add some flux to the pan before casting the ingots the slag should form a barrier between the muffin and the pan.
Great video! 4:40 no, the steel didn't melt it burned. Oxygen-acetylene cutting torches work by heating metal red hot then applying a jet of oxygen; red hot + 21% oxygen (less after the charcoal uses some of the O2) just cuts slower.
People should keep in mind, that steel is soluble to molten aluminum(the aluminum will eat through it like acid). Steel is an inadvisable crucible for aluminum. Stainless, depending on grade and finish, will likely handle a few fires. But should still be considered inadvisable. Never mind contamination.
I have a stainless steel 1/6 pan like from the kitchen, it has worked great, I can see how eventually it will fail but for me they super easy to get and nice to use
Any steel tools crucible,ladle and skimmer are coated beforehand in a wash of powdered clay and water to prevent the contact with the molten aluminum, problem solved.
IMPORTANT WARNING: if a steel crucible develops rust, DO NOT melt metal in it until you remove the rust or replace it. Molten aluminium/copper/zinc/tin will react violently with rust in a thermite reaction. This can burn or explode through the side of the furnace and bucket itself to spill hot metal everywhere. Thermite burns at 2000C, hot enough to cause 3rd degree burns instantly.
if you think that copper will make a thermite reaction then you know nothing about chemistry. copper is lower on the reactivity series and thus the displacement reaction will not occur
Jordan : Arc Welding temperatures occur around 6000°, steel melts at 2750°, but forge welding occurs around 2600°-2850° (borax based fluxes form gases that prevent atmosphere from entering the molten steel, thus preventing porosity). - a professional welder and blacksmith. Cheers :)
Thank you thank you! I've been making green sand and I just made my drag and cope and you pretty much answered any questions I had about my mini backyard foundry haha. This video was was awesome and very informative!
I did a DIY furnace about 50 years ago. Coke (not Coca cola), a vacuum cleaner and an old steel car rim, create the basis for a very effective and long lasting result. It will come to temperature very quickly and you shouldn't need any refractories. Stainless steel crucibles are fine for aluminium but an optical pyrometer is a must. There are plenty of individual grade analytical crucibles online for other metals. Cheers.
Carbon from wood and other biomass doesn't really count as it is part of the modern carbon cycle. The problem is that we're dumping carbon into the atmo that was sequestered millions of years ago, which overwhelms the modern carbon cycle.
With the carbon being put up from burning the charcoal, just think of it as being like you're having a miniature forest fire - it's throwing carbon up into atmo, yes, but it happens whether we affect it or not. However, when you burn things like coal, natural gas, or petro-hydrocarbons, which were pockets of carbon and other things hidden away out of the cycle for millions of years, just to be dumped out in a massive scale in the span of three to four centuries, then....
Sean That's not exactly true. Deforestation is also a huge contributor to global climate change, however the wood being used is probably from boreal forests which isn't a particularly huge issue.
+Cameron Bigley Meme. Conspiracy nuts claim the World Trade Center towers couldn't have been brought down by the damage of the plane crashes combined with the heat of the fires. "Jet fuel can't melt steel beams."
+Hardstyler981 Are you talking about the one that had generator fuel constantly pumped up from the basement and got hit by flaming debris from the towers?
So nice to see an average guy doing things in his backyard that most of us only dream of. Keep it up as i totally enjoy your work. Peace too !!!!!!!!!!

"Don't Build a Metal Foundry Until you See This First" Well there goes my plans for this weekend...
Lol
Same
Same here :(
I got lucky. I found this video before I had the idea of building a foundry.
I got an old oil stove to use for my coal foundry. Melted my cast iron pan first time...😁
I really like it. Not only is it very practical both for the hobbyist and the small businessman, the coolness factor for it being economical makes it even better
Thank you so much grant. After seeing your video the next day I tried and to create my own forge and was able to melt pewter as my first metal ever melted
I want to build my first metal foundry just because of you.
RIP 😭
Wow that is a gnarly looking graphite crucible. :) Thanks for all the great videos. You have been very instrumental in getting me into casting.
This was insanely informative. I've always wanted to get into metal forging as a hobby. For small weapons/jewelry etc. Definitely trying this.
Although this is an awesome idea, people need to be aware that this is extremely dangerous. My coworker had a piece of metal (that had an air bubble in it) explode on him and he was lucky to only have his leg and foot hit by the molten metal. It immediately burned through his shoes and gloves and caused such horrible burns that the doctors had to give him skin grafts and were very close to amputating his leg. It looked awful and he said he was in excruciating pain for about a week. If you are a beginner and are thinking of making this, BE CAREFUL.
we had a foundry in high school, you had to wear some pretty hardcore 'protective wear' in order to use said foundry

That's what makes this fun! The danger, the excitement, the fact that as a 15 year old so many people tell me not to make this!
THE SUN IS BRIGHT!!!!!!!!!
There's always risk with everything. Most dangerous place is your bathroom. Just showed how he built a inexpensive foundry
This whole metal foundry build is AWESOME I actually built my own using your instructional video on how to build it and it works AMAZINGLY WELL
I have absolutely no idea what any of this means but I find it interesting so I'm watching it
just got this video in my feed and realised how badly i miss u mate, rest in peace ❤
same :(

Those little metal muffins.. I...
I won't lie I... kinda wanna try to eat it...
Is just looks like a little cake wrapped in tinfoil.. I can't help it..

Ikr, if I could eat Metal like let's say Gajeel from FT, I'd be eating metal as what I eat everyday

I cut a one pound propane tank in half for a crucible. Worked well. Many are thrown away when they are empty.
Why am I even watching this?? I'm never going to do this
ikr
Just in case of a zombie apocalypse 8-)
never say never
When I have kids I'm totally going to do this with them. Beats kite-flying any day.
Sadonkers Pretty hot metal is fun to watch
2:26 So if I want to melt steel then I should use jet fuel right? Will that melt steel?
No, only steel beams
only 1 day a year
Foundry cant melt jetfuel
what inside a generator
Most interesting follow up, well beyond what I expected or hoped for, but that's how you roll! Thank you, sir, again for well thought out interesting and informative content.
I just made one of these and it worked awesome!! It got so hot, in fact, that I melted the stainless steel crucible! Thanks for the great design!
Okay, some words of caution are necessary here: 1) Anyone determined to melt aluminum drink cans should be mindful that they have proper masks for filtering fumes and are in a very well-ventilated area (outdoors is best), because the cans are coated with vinyl to prevent corrosion, which when burnt produces carcinogenic gases.
2) Make sure that any fire extinguishers you are going to use as crucibles are completely empty, because sawing through a pressurized container=Explosion hazard.
That aside, this is a neat idea for a lower cost foundry, I might have to try this model sometime.
I didn't know that and suspect a lot of people don't, so thanks for the heads up
This is true. Suitable masks for filtration should still be worn while using it, though. Use of fume extractors alongside them is even better.
2:27 so jetfuel cant melt steel?
but jets dont use propane to fly o.O
ElementalCraze g correct, they use jet fuel.
the metal would be flexible under the heat of the burning fuel, and the weight of the building pushing down on it would cause the building to collapse. so in this case, jetfuel melts steel beams
Amar Abidali even burning Wood will melt steel if you pump air in it. like old forges.
The only melting steel FEMA talks about is insipient melting in some of the steel found at the WTC. Insipient means the beginning of melting.
The insipient melting was due to sulfur contaminating the steel which caused corrosion, and would reduce the melting point in the areas of contamination (sulfur reduces the melting point of steel). So when it was subject to fire the steel almost melted in those affected patches.
The steel definitely did not turn to liquid. No one knows where the sulfur came from, nor whether it occurred during or before the events of 9/11. That is the only remaining mystery of those events as far as I'm concerned.
Been watching almost all of grants older vides today. and it hurts to know hes gone
yeah mate sometimes ur stressed out and you just watch his vids and you feel so relaxed but legends die too rip
One material I'm probably going to try when the weather gets a little warmer here. There is an old trick where you can carve a foundry from a loaf of stale bread then thoroughly char it over a grill. This creates a carbon foam. The problem with that foam is that it's not very dense and crumbles easily. However the density of the foam is proportional to the density of the bread. So my line of thinking is to set up a pipe inside the bucket the size of the cavity you want. Pack bread down into the section that will become the insulated wall as tightly as you can. Bake it over a fire until the bread is thoroughly charred into carbon foam and when it cools remove the pipe used to form the cavity.
Thank for this tutorial on this foundry I made it once and loved it Rest In Peace ✌️
I tried to melt aluminum cans using your mini forge, a couple years ago,with no real success. Thanks to this updated video, I'm going to try again, and I'm going to keep at it until I get it right! Thanks, King of Random!

Rewatching and makes me sad. Miss you man. Rip
The memories hit me hard.
This is great, lad. I think mixing melted aluminum, copper and tin together is a great one to do making your own kind of bronze.
Tin + Copper + Crushed Soda cans = Aluminum bronze!
These metal casting videos were the best. So inspiring.
Awesome video! Thanks for taking the time to help us rookies skip some mistakes! ✌️
I made muffins that seemingly welded themselves to my muffin pan. Not sure what I did wrong LOL. Wound up using the lower portion of a small blue propane canister that you'd use on a torch or lantern. Worked great the first 2 times I fired my foundry, then the third time, my hair dryer began spooling very high. Pulled out the air tube and out came 40 cans worth of aluminum. I'm not going to give up.
Was the muffin pan made out of steel? Cause if it were made out of something else, like, say, aluminum, that would be a problem.
seigeengine I purchased a cast iron muffin pan. It won't melt or have aluminum sticking to it.
It's possible your temperature was too high and you did actually weld the ally to the pan. What were you using for a flux? I'm pretty sure if you add some flux to the pan before casting the ingots the slag should form a barrier between the muffin and the pan.
And that's where I went wrong. What should I use for flux? Thanks for the pointer
or you may have used a aluminum pan
"The foundry will reach about 2,000 degrees and I know that because it will melt copper"
*throws in brass*
Brass is an alloy of Zinc and Copper. Are you unaware of this, or do you like to point out the obvious?
@@tcolondovich2996 Alloys have different melting temperatures, brass has a lower melting temp than copper
You do know what brass is made of right?
Give you a hint..
Copper and zinc
You're welcome
@@admjooge 200° difference
@@AFuqer4life That's still a fairly substantial difference
Great video!
4:40 no, the steel didn't melt it burned. Oxygen-acetylene cutting torches work by heating metal red hot then applying a jet of oxygen; red hot + 21% oxygen (less after the charcoal uses some of the O2) just cuts slower.
Does that mean that the forge got hotter than steel melting temperatures or did something else happen?
Could you combine all 3 videos into a shopping list so i could buy all the supplies i need? :)
+Jackson Keyes I put some links in the description that should help?
Jackson Keyes
People should keep in mind, that steel is soluble to molten aluminum(the aluminum will eat through it like acid). Steel is an inadvisable crucible for aluminum. Stainless, depending on grade and finish, will likely handle a few fires. But should still be considered inadvisable.
Never mind contamination.
cautions from the control brain programers?
I know im late but would that apply to copper as well?
I have a stainless steel 1/6 pan like from the kitchen, it has worked great, I can see how eventually it will fail but for me they super easy to get and nice to use
Any steel tools crucible,ladle and skimmer are coated beforehand in a wash of powdered clay and water to prevent the contact with the molten aluminum, problem solved.
Pegleg Noid, seems like a horrible idea to add any amount of water to something that you will then put molten metal in
IMPORTANT WARNING: if a steel crucible develops rust, DO NOT melt metal in it until you remove the rust or replace it. Molten aluminium/copper/zinc/tin will react violently with rust in a thermite reaction. This can burn or explode through the side of the furnace and bucket itself to spill hot metal everywhere. Thermite burns at 2000C, hot enough to cause 3rd degree burns instantly.
if you think that copper will make a thermite reaction then you know nothing about chemistry. copper is lower on the reactivity series and thus the displacement reaction will not occur
oh gee, sorry. The point still stands, no need to insult me.
compliments you are an excellent tech youtuber
if yours isnt working:
have you tried turning it on and off again?

Steel melts around 2850 degrees F. Welding temps are around 2400 F.
Then explain how welding melts steel.... -a welder
Okay?
Marcus Chauvin j
Jordan : Arc Welding temperatures occur around 6000°, steel melts at 2750°, but forge welding occurs around 2600°-2850° (borax based fluxes form gases that prevent atmosphere from entering the molten steel, thus preventing porosity). - a professional welder and blacksmith. Cheers :)
*_Where can I buy propane and propane accessories?_*
E.T.
Many outdoor shops have that, as well as some manned fuel stations, camping shops and online through exchange sites like craigslist.

Thank you thank you! I've been making green sand and I just made my drag and cope and you pretty much answered any questions I had about my mini backyard foundry haha. This video was was awesome and very informative!
Taken from us way too soon. All the best ones are. RIP legend!
ENORMOUS help ... Answered many questions ... Thanks KoR 👍
get my hands dirty? my hands will burn off so there will be no "hands to get dirty." lol
He means just be creative.
I did a DIY furnace about 50 years ago. Coke (not Coca cola), a vacuum cleaner and an old steel car rim, create the basis for a very effective and long lasting result. It will come to temperature very quickly and you shouldn't need any refractories. Stainless steel crucibles are fine for aluminium but an optical pyrometer is a must. There are plenty of individual grade analytical crucibles online for other metals.
Cheers.
Just use jet fuel to melt steel.... Oh wait!
It can melt steel
@@RuKe1 no it can't.
@@themonsterunderyourbed9408 yes it can it melted steel in the world trade center
now we know where the global warming comes from when 100 000 people know how to make metal foundries, lol

Carbon from wood and other biomass doesn't really count as it is part of the modern carbon cycle. The problem is that we're dumping carbon into the atmo that was sequestered millions of years ago, which overwhelms the modern carbon cycle.
With the carbon being put up from burning the charcoal, just think of it as being like you're having a miniature forest fire - it's throwing carbon up into atmo, yes, but it happens whether we affect it or not. However, when you burn things like coal, natural gas, or petro-hydrocarbons, which were pockets of carbon and other things hidden away out of the cycle for millions of years, just to be dumped out in a massive scale in the span of three to four centuries, then....
Sean
That's not exactly true. Deforestation is also a huge contributor to global climate change, however the wood being used is probably from boreal forests which isn't a particularly huge issue.
Metal Foundry wont melt steel beams
+Cameron Bigley
Meme. Conspiracy nuts claim the World Trade Center towers couldn't have been brought down by the damage of the plane crashes combined with the heat of the fires. "Jet fuel can't melt steel beams."
TiagoTiago one got attacked by above and the whole building fell dowm doesnt make sense
+Hardstyler981 Are you talking about the one that had generator fuel constantly pumped up from the basement and got hit by flaming debris from the towers?
So nice to see an average guy doing things in his backyard that most of us only dream of. Keep it up as i totally enjoy your work. Peace too !!!!!!!!!!
To keep Your Propane Tank from Freezing up, Just open the Valve only about 3/4 turn. I fund this out when I was Spinning Titanium.

i initially had no interest in this but somehow my youtube turned this on and now im heavily considering making this in my backyard lol! i wanna make all kinds of things
Lyv Rue you should check out some of my casting fails and successes to get an idea on what to do and not to do . Who knows you might actually like my channel🤔?
About a year ago I tried to break a strand of steel wool with my hands.
VERY BAD IDEA
WesOfX lol
WesOfX what happened it just ripped up for me
AAG- AllAroundGaming one strand, not the steel wool as a whole.

If you try to break a strand you'll likely cut your hand (excuse the rhyme)
WesOfX Yes, stainless steel strands are very sharp and strong. I got annoyed with a strand catching on the plug-chain whilst doing washing up, tugged it, and sliced my finger 😢
