okay what’s up guys today I’m out here with my mini metal foundry because we’re
with my mini metal foundry because we’re
with my mini metal foundry because we’re celebrating a milestone the video on

over one hundred thousand likes now when I first made the metal foundry
now when I first made the metal foundry
now when I first made the metal foundry I had no idea that so many of you would
I had no idea that so many of you would
I had no idea that so many of you would actually be making this yourselves and
actually be making this yourselves and
actually be making this yourselves and as a result a lot of you have had

questions and concerns and left comments about failures and mistakes that have
about failures and mistakes that have
about failures and mistakes that have been made and I wanted to update you
been made and I wanted to update you
been made and I wanted to update you through this video about some of the
through this video about some of the
through this video about some of the personal tips and tricks that I started
personal tips and tricks that I started
personal tips and tricks that I started using that may solve those problems for
using that may solve those problems for
using that may solve those problems for you the mini metal foundry is made of
you the mini metal foundry is made of
you the mini metal foundry is made of some very basic materials it’s just a
some very basic materials it’s just a
some very basic materials it’s just a steel bucket with a little bit of sand
steel bucket with a little bit of sand
steel bucket with a little bit of sand some plaster of Paris and some water to
some plaster of Paris and some water to
some plaster of Paris and some water to create just enough of an insulating
create just enough of an insulating
create just enough of an insulating layer that you can heat up and melt
layer that you can heat up and melt
layer that you can heat up and melt metals like aluminium brass and even
metals like aluminium brass and even
metals like aluminium brass and even silver and gold okay now some people
silver and gold okay now some people
silver and gold okay now some people would like to know why did I design the
would like to know why did I design the
would like to know why did I design the metal foundry out of sand and plaster
metal foundry out of sand and plaster
metal foundry out of sand and plaster when I could have used refractory cement
when I could have used refractory cement
when I could have used refractory cement chalo wool or other higher quality
chalo wool or other higher quality
chalo wool or other higher quality refractory materials like that and the
refractory materials like that and the
refractory materials like that and the answer is simple
answer is simple
answer is simple when I design the metal foundry I wanted
when I design the metal foundry I wanted
when I design the metal foundry I wanted it to be relatable I wanted most people
it to be relatable I wanted most people
it to be relatable I wanted most people to be able to go out and buy simple
to be able to go out and buy simple
to be able to go out and buy simple commonly available materials and put
commonly available materials and put
commonly available materials and put together a backyard foundry that would
together a backyard foundry that would
together a backyard foundry that would work now along with that using cheaper
work now along with that using cheaper
work now along with that using cheaper materials means that the system is going
materials means that the system is going
materials means that the system is going to break down a little bit faster one of
to break down a little bit faster one of
to break down a little bit faster one of the most common pieces of feedback I’ve
the most common pieces of feedback I’ve
the most common pieces of feedback I’ve had from people is that after two or
had from people is that after two or
had from people is that after two or three firings the lid starts to crack
three firings the lid starts to crack
three firings the lid starts to crack and crumble and break and that’s not
and crumble and break and that’s not
and crumble and break and that’s not just you guys that happens to me as well
just you guys that happens to me as well
just you guys that happens to me as well but I figured out a cool little trick
but I figured out a cool little trick
but I figured out a cool little trick you can do it’ll make it last about 10
you can do it’ll make it last about 10
you can do it’ll make it last about 10 times longer and all you need is a
times longer and all you need is a
times longer and all you need is a little bit of steel wool I went down to
little bit of steel wool I went down to
little bit of steel wool I went down to the hardware store and found some of the
the hardware store and found some of the
the hardware store and found some of the courses steel wool I could get and when
courses steel wool I could get and when
courses steel wool I could get and when you unravel the bundle you can see it
you unravel the bundle you can see it
you unravel the bundle you can see it rolls out into long strands of steel
rolls out into long strands of steel
rolls out into long strands of steel which is kind of like a metal spiderweb
which is kind of like a metal spiderweb
which is kind of like a metal spiderweb and the idea is to push this down into
and the idea is to push this down into
and the idea is to push this down into the plaster and sand mix while it’s
the plaster and sand mix while it’s
the plaster and sand mix while it’s still wet because this metal mesh will
still wet because this metal mesh will
still wet because this metal mesh will help reinforce the sand in the plaster
help reinforce the sand in the plaster
help reinforce the sand in the plaster and hold everything together about ten
and hold everything together about ten
and hold everything together about ten times longer than it would without it if
times longer than it would without it if
times longer than it would without it if you want to get even more mileage out of
you want to get even more mileage out of
you want to get even more mileage out of your metal foundry than try using
your metal foundry than try using
your metal foundry than try using stainless steel strands instead of the
stainless steel strands instead of the
stainless steel strands instead of the steel wool you can get stainless steel
steel wool you can get stainless steel
steel wool you can get stainless steel strands in things like brillo pads which
strands in things like brillo pads which
strands in things like brillo pads which are gonna be a lot more expensive but it
are gonna be a lot more expensive but it
are gonna be a lot more expensive but it should hold up a lot longer in the same
should hold up a lot longer in the same
should hold up a lot longer in the same kind of conditions another one of the
kind of conditions another one of the
kind of conditions another one of the benefits of the metal foundry is it’s
benefits of the metal foundry is it’s
benefits of the metal foundry is it’s very easy to make over time the walls
very easy to make over time the walls
very easy to make over time the walls will start crumbling but you can just
will start crumbling but you can just
will start crumbling but you can just bang all that crud out with a hammer and
bang all that crud out with a hammer and
bang all that crud out with a hammer and mix up a new batch and in 20 minutes
mix up a new batch and in 20 minutes
mix up a new batch and in 20 minutes you’ve got yourself a brand new system a
you’ve got yourself a brand new system a
you’ve got yourself a brand new system a bag of plaster and a bag of sand
bag of plaster and a bag of sand
bag of plaster and a bag of sand together will cost about $20 but the
together will cost about $20 but the
together will cost about $20 but the cool thing is you can make between two
cool thing is you can make between two
cool thing is you can make between two and three metal founders with it now
and three metal founders with it now
and three metal founders with it now some people wonder if you can use cement
some people wonder if you can use cement
some people wonder if you can use cement or concrete instead of plaster of Paris
or concrete instead of plaster of Paris
or concrete instead of plaster of Paris and I would strongly caution you not to
and I would strongly caution you not to
and I would strongly caution you not to the reason is
the reason is
the reason is if there’s any moisture trapped in the
if there’s any moisture trapped in the
if there’s any moisture trapped in the concrete then when it heats up there’s
concrete then when it heats up there’s
concrete then when it heats up there’s the potential it could explode in your
the potential it could explode in your
the potential it could explode in your face on the other hand plaster of Paris
face on the other hand plaster of Paris
face on the other hand plaster of Paris and sand are very porous so they vent
and sand are very porous so they vent
and sand are very porous so they vent the gasses off and there’s very very low
the gasses off and there’s very very low
the gasses off and there’s very very low risk of that happening at all now the
risk of that happening at all now the
risk of that happening at all now the foundry will reach temperatures up
foundry will reach temperatures up
foundry will reach temperatures up around 2,000 degrees Fahrenheit and I
around 2,000 degrees Fahrenheit and I
around 2,000 degrees Fahrenheit and I know that because of a melt copper and
know that because of a melt copper and
know that because of a melt copper and if it can melt copper it’ll melt silver
if it can melt copper it’ll melt silver
if it can melt copper it’ll melt silver and gold as well but it probably won’t
and gold as well but it probably won’t
and gold as well but it probably won’t melt steel steel has a melting point up
melt steel steel has a melting point up
melt steel steel has a melting point up around 2300 to 2400 degrees Fahrenheit
around 2300 to 2400 degrees Fahrenheit
around 2300 to 2400 degrees Fahrenheit so you might be able to use the metal
so you might be able to use the metal
so you might be able to use the metal foundry to help you forge steel but
foundry to help you forge steel but
foundry to help you forge steel but you’re not going to be able to melt it
you’re not going to be able to melt it
you’re not going to be able to melt it down and cast with it
down and cast with it
down and cast with it okay let’s talk about crucibles now I
okay let’s talk about crucibles now I
okay let’s talk about crucibles now I used a fire extinguisher for my crucible
used a fire extinguisher for my crucible
used a fire extinguisher for my crucible and that was mainly just to show that it
and that was mainly just to show that it
and that was mainly just to show that it could be done in an apocalyptic
could be done in an apocalyptic
could be done in an apocalyptic situation I certainly wasn’t
situation I certainly wasn’t
situation I certainly wasn’t recommending that a fire extinguisher
recommending that a fire extinguisher
recommending that a fire extinguisher was the best way to go but it’s blowing
was the best way to go but it’s blowing
was the best way to go but it’s blowing my mind how many comments and questions
my mind how many comments and questions
my mind how many comments and questions I got from people asking where to get
I got from people asking where to get
I got from people asking where to get fire extinguishers or that they bought a
fire extinguishers or that they bought a
fire extinguishers or that they bought a fire extinguisher only to find out that
fire extinguisher only to find out that
fire extinguisher only to find out that it melted in the foundry let’s address
it melted in the foundry let’s address
it melted in the foundry let’s address that issue first first of all if your
that issue first first of all if your

got my news from an industrial equipment
got my news from an industrial equipment supplier but that’s not going to be the
supplier but that’s not going to be the
supplier but that’s not going to be the typical story for you by far by far by
typical story for you by far by far by
typical story for you by far by far by far by far the best crucible I’ve ever
far by far the best crucible I’ve ever
far by far the best crucible I’ve ever used is called a clay graphite crucible
used is called a clay graphite crucible
used is called a clay graphite crucible and it’s one that I found off the
and it’s one that I found off the
and it’s one that I found off the internet for about 30 to 40 dollars now
internet for about 30 to 40 dollars now
internet for about 30 to 40 dollars now it seems like a little bit of investment
it seems like a little bit of investment
it seems like a little bit of investment but trust me a fire extinguisher isn’t
but trust me a fire extinguisher isn’t
but trust me a fire extinguisher isn’t gonna be any cheaper and the clay
gonna be any cheaper and the clay
gonna be any cheaper and the clay graphite crucible is gonna last a lot
graphite crucible is gonna last a lot
graphite crucible is gonna last a lot longer I personally put mine through

in there and it actually got so hot that
in there and it actually got so hot that it melted the steel and all the aluminum
it melted the steel and all the aluminum
it melted the steel and all the aluminum leaked out so if you use lump charcoal
leaked out so if you use lump charcoal
leaked out so if you use lump charcoal it will burn a lot hotter it’s very very
