hey guys welcome back to another day of backyard metal melting in yesterday’s
backyard metal melting in yesterday’s
backyard metal melting in yesterday’s video I tried using green sand casting
video I tried using green sand casting
video I tried using green sand casting and some styrofoam to create a custom
and some styrofoam to create a custom
and some styrofoam to create a custom copper gear the problem is it didn’t
copper gear the problem is it didn’t
copper gear the problem is it didn’t turn out as perfectly as I wanted it to
turn out as perfectly as I wanted it to
turn out as perfectly as I wanted it to and I think that’s because copper has a
and I think that’s because copper has a
and I think that’s because copper has a really high melting point which means it
really high melting point which means it
really high melting point which means it cools down a little bit too quickly so
cools down a little bit too quickly so
cools down a little bit too quickly so for this video I wanted to revisit that
for this video I wanted to revisit that
for this video I wanted to revisit that experiment because my OCD is kicking in
experiment because my OCD is kicking in
experiment because my OCD is kicking in and I want to get one of these things
and I want to get one of these things
and I want to get one of these things near perfect now I just took my copper
near perfect now I just took my copper
near perfect now I just took my copper gear that I’m not extremely proud of and
gear that I’m not extremely proud of and
gear that I’m not extremely proud of and I cut it in half so that we can remelt
I cut it in half so that we can remelt
I cut it in half so that we can remelt it and I also made a trip down to the
it and I also made a trip down to the
it and I also made a trip down to the hardware store and got another $30 of
hardware store and got another $30 of
hardware store and got another $30 of copper tubing and this time we just cut
copper tubing and this time we just cut
copper tubing and this time we just cut it and smashed it flat so we can cram
it and smashed it flat so we can cram
it and smashed it flat so we can cram more of it in the crucible so believe it
more of it in the crucible so believe it
more of it in the crucible so believe it or not this a little bit of metal here
or not this a little bit of metal here
or not this a little bit of metal here you’re looking at about $60 of copper I
you’re looking at about $60 of copper I
you’re looking at about $60 of copper I also have a little copper nugget left
also have a little copper nugget left
also have a little copper nugget left over from the casting we did yesterday
over from the casting we did yesterday
over from the casting we did yesterday so I’m going to throw that back in load
so I’m going to throw that back in load
so I’m going to throw that back in load this crucible up with copper and then
this crucible up with copper and then
this crucible up with copper and then prep our sand casting mold for another
prep our sand casting mold for another
prep our sand casting mold for another round okay we’re going to stick this in
round okay we’re going to stick this in
round okay we’re going to stick this in and let it
and let it
and let it [Music]

so update guys we just got our styrofoam
so update guys we just got our styrofoam gear set back in the box we’ve got our
gear set back in the box we’ve got our
gear set back in the box we’ve got our green tent packed in nice and tight
green tent packed in nice and tight
green tent packed in nice and tight and we are ready to cast once again I
and we are ready to cast once again I
and we are ready to cast once again I think one of the problems we were having
think one of the problems we were having
think one of the problems we were having yesterday when we report in the copper
yesterday when we report in the copper
yesterday when we report in the copper is we waited too long to get it into the
is we waited too long to get it into the
is we waited too long to get it into the mold one very interesting observation we
mold one very interesting observation we
mold one very interesting observation we saw was as we got the crucible close to
saw was as we got the crucible close to
saw was as we got the crucible close to the styrofoam it melted just from the
the styrofoam it melted just from the
the styrofoam it melted just from the radiant heat and that was very cool
radiant heat and that was very cool
radiant heat and that was very cool but the solidifying point of copper is
but the solidifying point of copper is
but the solidifying point of copper is very very high so even just having the
very very high so even just having the
very very high so even just having the crucible up for 35 to 40 seconds I think
crucible up for 35 to 40 seconds I think
crucible up for 35 to 40 seconds I think made so much of a difference that it
made so much of a difference that it
made so much of a difference that it wasn’t quite as liquid as we needed it
wasn’t quite as liquid as we needed it
wasn’t quite as liquid as we needed it to be
to be
to be so we tried pouring our copper this time
so we tried pouring our copper this time
so we tried pouring our copper this time I’m going to try it in two stages on the
I’m going to try it in two stages on the
I’m going to try it in two stages on the first pass I’m going to take the
first pass I’m going to take the
first pass I’m going to take the crucible out and use the heat to melt
crucible out and use the heat to melt
crucible out and use the heat to melt down the styrofoam and then place the
down the styrofoam and then place the
down the styrofoam and then place the crucible back in the foundry I’m going
crucible back in the foundry I’m going
crucible back in the foundry I’m going to let it heat up for about another five
to let it heat up for about another five
to let it heat up for about another five to ten minutes so it’s ripping hot so
to ten minutes so it’s ripping hot so
to ten minutes so it’s ripping hot so we’re going to pull the crucible back
we’re going to pull the crucible back
we’re going to pull the crucible back out and pour the copper immediately
out and pour the copper immediately
out and pour the copper immediately before it has any chance to cool down
before it has any chance to cool down
before it has any chance to cool down and see if we get any better results
and see if we get any better results
and see if we get any better results with that method nice and toasty you can
with that method nice and toasty you can
with that method nice and toasty you can see it hasn’t quite melted yet that’s
see it hasn’t quite melted yet that’s
see it hasn’t quite melted yet that’s okay because we don’t need it most in
okay because we don’t need it most in
okay because we don’t need it most in yet we’re just going to use this to melt
yet we’re just going to use this to melt
yet we’re just going to use this to melt the styrofoam all right now we’re just
the styrofoam all right now we’re just
the styrofoam all right now we’re just going to use the heat from the crucible
going to use the heat from the crucible
going to use the heat from the crucible look at that
look at that
look at that oh I think my crucible touched the top
oh I think my crucible touched the top
oh I think my crucible touched the top of the sand oh no it did okay so that
of the sand oh no it did okay so that
of the sand oh no it did okay so that was kind of a bummer guys I got the
was kind of a bummer guys I got the
was kind of a bummer guys I got the crucible to close and actually made
crucible to close and actually made
crucible to close and actually made contact with the stand which crushed it
contact with the stand which crushed it
contact with the stand which crushed it and kind of ruin my mold so I’m gonna
and kind of ruin my mold so I’m gonna
and kind of ruin my mold so I’m gonna have to use my other styrofoam gear and
have to use my other styrofoam gear and
have to use my other styrofoam gear and make another one kind of cool though
make another one kind of cool though
make another one kind of cool though look at that it makes like a styrofoam
look at that it makes like a styrofoam
look at that it makes like a styrofoam shell it’s all it on this side shell on
shell it’s all it on this side shell on
shell it’s all it on this side shell on this side what’s kind of interesting all
this side what’s kind of interesting all
this side what’s kind of interesting all right another fail you can see that
right another fail you can see that
right another fail you can see that copper hasn’t melted yet but that’s okay
copper hasn’t melted yet but that’s okay
copper hasn’t melted yet but that’s okay because we’re just going to use that
because we’re just going to use that
because we’re just going to use that radiant heat to burn out this parasol oh
[Music]
[Music] that’s
[Applause]
[Applause] [Music]
[Music]
[Music] all right put the food back in with a
all right put the food back in with a
all right put the food back in with a nice and molten there in the bottom
all right I think that’s good enough I’m
all right I think that’s good enough I’m tempted to try and pull the styrofoam
tempted to try and pull the styrofoam
tempted to try and pull the styrofoam out but pretty sure I’m going to wreck
out but pretty sure I’m going to wreck
out but pretty sure I’m going to wreck the mold if I do so I’m just going to
the mold if I do so I’m just going to
the mold if I do so I’m just going to leave that last layer on there fire the
leave that last layer on there fire the
leave that last layer on there fire the copper up until it’s ripping hot and
copper up until it’s ripping hot and
copper up until it’s ripping hot and then pour it right in the center and let
then pour it right in the center and let
then pour it right in the center and let it flow out so see if that works any
it flow out so see if that works any
it flow out so see if that works any better fingers crossed
better fingers crossed
better fingers crossed in the meantime we’ll cover it up to
in the meantime we’ll cover it up to
in the meantime we’ll cover it up to keep it clean update guys I think our
keep it clean update guys I think our
keep it clean update guys I think our copper is just about ready it’s been
copper is just about ready it’s been
copper is just about ready it’s been sitting in the foundry for over 20
sitting in the foundry for over 20
sitting in the foundry for over 20 minutes and it looks really really hot
minutes and it looks really really hot
minutes and it looks really really hot our mold is prepped and ready to go so
our mold is prepped and ready to go so
our mold is prepped and ready to go so let’s go ahead and turn off the foundry
let’s go ahead and turn off the foundry
let’s go ahead and turn off the foundry and see just how quickly we can actually
and see just how quickly we can actually
and see just how quickly we can actually make the transfer all right time is our
make the transfer all right time is our
make the transfer all right time is our enemy

a lot of proper right look at just oh
a lot of proper right look at just oh man it just popped out that chunk of
man it just popped out that chunk of
man it just popped out that chunk of sand the sand just came out that’s
sand the sand just came out that’s
sand the sand just came out that’s really discouraging what is up with this
really discouraging what is up with this
really discouraging what is up with this guy’s what is up with this look it

and this thing is already cooled down
and this thing is already cooled down well maybe not affect it still click I
well maybe not affect it still click I
well maybe not affect it still click I could still break that and chunk it pour
could still break that and chunk it pour
could still break that and chunk it pour that back and boundary then okay failing
that back and boundary then okay failing
that back and boundary then okay failing all over the place
all over the place
all over the place why cannot we get this to work well I
why cannot we get this to work well I
why cannot we get this to work well I guess we just make another one so I have
guess we just make another one so I have
guess we just make another one so I have to admit at this point I’m a little bit
to admit at this point I’m a little bit
to admit at this point I’m a little bit lost burning out the mold didn’t seem to
lost burning out the mold didn’t seem to
lost burning out the mold didn’t seem to make a difference if anything it kind of
make a difference if anything it kind of
make a difference if anything it kind of left us and go in the sand flow to the
left us and go in the sand flow to the
left us and go in the sand flow to the top so at this point I’m just going to
top so at this point I’m just going to
top so at this point I’m just going to have made a new styrofoam gear we’re
have made a new styrofoam gear we’re
have made a new styrofoam gear we’re going to take the copper out pour it as
going to take the copper out pour it as
going to take the copper out pour it as fast as we can and hope for the best
fast as we can and hope for the best
fast as we can and hope for the best here we go that looks toasty alright
here we go that looks toasty alright
here we go that looks toasty alright quickly quickly
quickly quickly
quickly quickly [Music]
oh that was definitely more molten but
oh that was definitely more molten but look another one of our little sand
look another one of our little sand
look another one of our little sand pieces came out right that’s because our
pieces came out right that’s because our
pieces came out right that’s because our green sand isn’t quite stable you know
green sand isn’t quite stable you know
green sand isn’t quite stable you know that is very very frustrating I’m
that is very very frustrating I’m
that is very very frustrating I’m getting very upset about that everything
getting very upset about that everything
getting very upset about that everything about that was beautiful it’s a little
about that was beautiful it’s a little
about that was beautiful it’s a little chunky no
that looks pretty cool though huh oh
that looks pretty cool though huh oh that was almost perfect so close so here
that was almost perfect so close so here
that was almost perfect so close so here we are guys I went ahead and made
we are guys I went ahead and made
we are guys I went ahead and made another one I think technically this is
another one I think technically this is
another one I think technically this is our sixth Foam gear we’ve tried casting
our sixth Foam gear we’ve tried casting
our sixth Foam gear we’ve tried casting I did something a little bit different
I did something a little bit different
I did something a little bit different this time I went to sand down a little
this time I went to sand down a little
this time I went to sand down a little bit more I’m thinking part of the
bit more I’m thinking part of the
bit more I’m thinking part of the problem we were having earlier is maybe
problem we were having earlier is maybe
problem we were having earlier is maybe the stand was a little bit too dry
the stand was a little bit too dry
the stand was a little bit too dry that’s why it was flaking out so I added
that’s why it was flaking out so I added
that’s why it was flaking out so I added a bit more moisture now the things that
a bit more moisture now the things that
a bit more moisture now the things that we’ve got a new batch of copper melted
we’ve got a new batch of copper melted
we’ve got a new batch of copper melted so we’re going to give it a pour and
so we’re going to give it a pour and
so we’re going to give it a pour and just hold our breath and hope it works
just hold our breath and hope it works
just hold our breath and hope it works if it doesn’t I think we’re just going
if it doesn’t I think we’re just going
if it doesn’t I think we’re just going to go with whatever we get because I’m
to go with whatever we get because I’m

after six attempts here I’m starting to
after six attempts here I’m starting to lose confidence that casting copper and
