*What's up guys?! I've been wanting to make this video forever and really happy it's finally done. I hope it helps answer all your questions!

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.
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!
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.
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.
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..
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.
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.
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.
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
+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?
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.
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.
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'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
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 😢
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.
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.
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.
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. 😜
What a cool dude, I didn't find these videos until after his passing, it's too bad because they are very inspiring and neat for helping and motivating and what not
I make TV shows for a living, Salty. My criteria for as to whether a show is well made, is if it makes me interested in a subject for which I have no interest. This piece just scored a bulls eye with me TOO.
You take plastic bottle caps that can be recycled and have number 2 recycle symbol. When heated they will be softer so with a form and some pressure applied you will get most of the parts done. When you need it more precise you can do it in few parts and stick them together with super glue, for better connection i suggest scratching the surface and even making few small holes.Then all you need is the center which you can make easily as well, you just need to think about how you want it to work. And about the circular parts. I already checked it, its easy to calculate everything when you decide the cube size.
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.
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.
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🤔?
+super gaming I appreciate you sharing what your parents greet you with once you come home from school everyday (assuming you have not dropped out yet) but I honestly don't care.
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!
8:46 i too did the same, that lump charcoal is power full stuff, it melted a hole in the steel glass and all the aluminum leaked out. You dont need a foundry for melting aluminums and other metals melting at lower temperatures, just a hole dug in ground is enough along with an air blower.
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
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.
Nah, it's very risky and requires a level of carefulness and attention that many (including me) just can't achieve. Still, seeing a guy make metal models of weapons, toys and stuff alike is cool as heck. :v
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.
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.
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.
Durring the summer I'm getting a job so I can get the materials to make my own foundry. I'm trying to get into the UA-cam business and I'm starting from the bottom and going up. Your videos are very helpful and are really interesting. 👍
I have been wanting to get into black smithing and casting. This foundry looks like just the thing. I dig that it's charcoal powered since charcoal is easy enough to get. I like how you melted down the cartridge casings. It might be worth contacting a local range to see if they have brass I can have.
You (The King of Random) are amazingly smart, very intelligent, full of innovation & ingenuity, it just blow my mind to think that you are from this planet Earth! You must be from another higher advanced civilization world \ planet! I want to thank you for posting updates, tips, improvements and the don'ts & do of mini metal foundry for all hobbyists out there!

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.

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.
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
"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

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
*_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.

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 a cool dude, I didn't find these videos until after his passing, it's too bad because they are very inspiring and neat for helping and motivating and what not
Why am I watching this? I don't even know what a metal foundry is . . .
Salty ikr😂
that's why u watch it
I make TV shows for a living, Salty. My criteria for as to whether a show is well made, is if it makes me interested in a subject for which I have no interest.
This piece just scored a bulls eye with me TOO.
Salty it melts meat duh
LMAO Saaame I don't know how I even got here but I watched and listened to every word said >_
I feel so old now! 2 years ago. Ugh... Thanks Grant!
TheGamingFireUltra you feel old because of that?😂
Because you said this, I'm guessing that you're under 30. If so, you're not old. You're not really even elderly until you're in your sixties.
His videos would suggest he is a lot younger.
what, you're like 7 now?
My question is: Can you make a rubic's cube with bottle caps? Well thats a question i said to myself, but if you want to go ahead and do it! :D
MiniaczQ how tf would that work
You take plastic bottle caps that can be recycled and have number 2 recycle symbol. When heated they will be softer so with a form and some pressure applied you will get most of the parts done. When you need it more precise you can do it in few parts and stick them together with super glue, for better connection i suggest scratching the surface and even making few small holes.Then all you need is the center which you can make easily as well, you just need to think about how you want it to work. And about the circular parts. I already checked it, its easy to calculate everything when you decide the cube size.
MiniaczQ Learn how to spell Rubik's
Well i don't use the english name that much, so don't mind for writing it wrong.
Russell's EditsTM Quack.
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.
if yours isnt working:
have you tried turning it on and off again?

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
Wow. Lol this was insanely wonderful. Thank you for taking the time to share - it is really appreciated. Fabulous. Regards Lee (UK)
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🤔?

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!

Did it work
Ebay is about to be flooded with random metal castings!
lol hahaha
Lol... Funniest comment.😃👍...
Because you know it's true... 😀
“Random”
Brass is made with copper
8:46 i too did the same, that lump charcoal is power full stuff, it melted a hole in the steel glass and all the aluminum leaked out. You dont need a foundry for melting aluminums and other metals melting at lower temperatures, just a hole dug in ground is enough along with an air blower.
ENORMOUS help ... Answered many questions ... Thanks KoR 👍

Your quick speaking style is a style I wish more vloggers would use.
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.
Then: mini metal foundry
Now: microwaving a highlighter
so true lmao
sorry they patched it in update 2.0

I wish the best for your family and rest in peace
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.
i watch it even though i won't try it ever, is it just me or do i need to see a doctor?
Nah, it's very risky and requires a level of carefulness and attention that many (including me) just can't achieve.
Still, seeing a guy make metal models of weapons, toys and stuff alike is cool as heck. :v
LMAO same here :P too paranoid i'll burn the house down X( LOL
Psychoo It's not just you, so go see a doctor.
I really liked the fact that hes a fast talker and delivers his points quickly. I also liked that you followed everything with a reason as to why.

Thankyou now I can melt aluminium and pour it down ant hills

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.
If you do not like it, then don't watch it.
agreed! though well thought out clearly is involved by one who has the capacity to do!
he clearly states that he likes it. what makes you think that he doesn't like the video? did you even read his comment????
They misread the award he was talking about. They probably read "There should be an award for MOST useless video on youtube."
Dude don’t watch it
You are really a professional...
two questions: #1 how do you monitor temperatures while using this foundry?
#2 Are you using propane and briquettes in your video?
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.
Wow that is a gnarly looking graphite crucible. :) Thanks for all the great videos. You have been very instrumental in getting me into casting.
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.
Durring the summer I'm getting a job so I can get the materials to make my own foundry. I'm trying to get into the UA-cam business and I'm starting from the bottom and going up. Your videos are very helpful and are really interesting. 👍

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
I have been wanting to get into black smithing and casting. This foundry looks like just the thing. I dig that it's charcoal powered since charcoal is easy enough to get. I like how you melted down the cartridge casings. It might be worth contacting a local range to see if they have brass I can have.
TeleTrans 1 the range isn’t going to give you any brass. They sell it for scrap.
I have absolutely no idea what any of this means but I find it interesting so I'm watching it
