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

[Music]
so update guys we just got our styrofoam
gear set back in the box we’ve got our
green tent packed in nice and tight
and we are ready to cast once again I
think one of the problems we were having
yesterday when we report in the copper
is we waited too long to get it into the
mold one very interesting observation we
saw was as we got the crucible close to
the styrofoam it melted just from the
radiant heat and that was very cool
but the solidifying point of copper is
very very high so even just having the
crucible up for 35 to 40 seconds I think
made so much of a difference that it
wasn’t quite as liquid as we needed it
to be
so we tried pouring our copper this time
I’m going to try it in two stages on the
first pass I’m going to take the
crucible out and use the heat to melt
down the styrofoam and then place the
crucible back in the foundry I’m going
to let it heat up for about another five
to ten minutes so it’s ripping hot so
we’re going to pull the crucible back
out and pour the copper immediately
before it has any chance to cool down
and see if we get any better results
with that method nice and toasty you can
see it hasn’t quite melted yet that’s
okay because we don’t need it most in
yet we’re just going to use this to melt
the styrofoam all right now we’re just
going to use the heat from the crucible
look at that
oh I think my crucible touched the top
of the sand oh no it did okay so that
was kind of a bummer guys I got the
crucible to close and actually made
contact with the stand which crushed it
and kind of ruin my mold so I’m gonna
have to use my other styrofoam gear and
make another one kind of cool though
look at that it makes like a styrofoam
shell it’s all it on this side shell on
this side what’s kind of interesting all
right another fail you can see that
copper hasn’t melted yet but that’s okay
because we’re just going to use that
radiant heat to burn out this parasol oh
[Music]
that’s
and itself don’t get too close
[Applause]
[Music]
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
tempted to try and pull the styrofoam
out but pretty sure I’m going to wreck
the mold if I do so I’m just going to
leave that last layer on there fire the
copper up until it’s ripping hot and
then pour it right in the center and let
it flow out so see if that works any
better fingers crossed
in the meantime we’ll cover it up to
keep it clean update guys I think our
copper is just about ready it’s been
sitting in the foundry for over 20
minutes and it looks really really hot
our mold is prepped and ready to go so
let’s go ahead and turn off the foundry
and see just how quickly we can actually
make the transfer all right time is our
enemy
that looks riffin hot over here and you
pour
[Applause]
[Music]
a lot of proper right look at just oh
man it just popped out that chunk of
sand the sand just came out that’s
really discouraging what is up with this
guy’s what is up with this look it
didn’t even complete there either
and this thing is already cooled down
well maybe not affect it still click I
could still break that and chunk it pour
that back and boundary then okay failing
all over the place
why cannot we get this to work well I
guess we just make another one so I have
to admit at this point I’m a little bit
lost burning out the mold didn’t seem to
make a difference if anything it kind of
left us and go in the sand flow to the
top so at this point I’m just going to
have made a new styrofoam gear we’re
going to take the copper out pour it as
fast as we can and hope for the best
here we go that looks toasty alright
quickly quickly
[Music]
oh that was definitely more molten but
look another one of our little sand
pieces came out right that’s because our
green sand isn’t quite stable you know
that is very very frustrating I’m
getting very upset about that everything
about that was beautiful it’s a little
chunky no
that looks pretty cool though huh oh
that was almost perfect so close so here
we are guys I went ahead and made
another one I think technically this is
our sixth Foam gear we’ve tried casting
I did something a little bit different
this time I went to sand down a little
bit more I’m thinking part of the
problem we were having earlier is maybe
the stand was a little bit too dry
that’s why it was flaking out so I added
a bit more moisture now the things that
we’ve got a new batch of copper melted
so we’re going to give it a pour and
just hold our breath and hope it works
if it doesn’t I think we’re just going
to go with whatever we get because I’m
not doing that again
let’s rock is our last chance so we
better work all right here you go
[Music]
[Applause]
Oh see those 10% still popping out their
toes all three of them popped out no way
the rest of the gear shape filled up
pretty nicely though it’d take these
chunks of standout headaches overdrive
well that looks a little more molten
this time our copper was hot enough to
even out the only problem was the little
impressions of our sin top that as well
staying it oh well I’m going with it
I got a copper here I’m keeping it I’m
calling it good that’s harden up quite a
bit sure does get crispy crispy fan
let’s see how well that held its shape
well it actually looks pretty decent on
that side I like it oh look it’s
actually got a little radioactive
indentations there let sniff looks like
it cool down a little bit before it
popped off oh look at that obviously
still hot
go ahead and quench it in a bucket of
water
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
well guys I feel like that took way way
longer than I ever wanted it to take and
after six attempts here I’m starting to
lose confidence that casting copper and
Greenspan is even a viable idea at all
I’ve never actually seen anybody else do
it and that’s why I want to try for
myself but it seems the two problems we
keep running into is either the copper
cooled down too quickly to form an ice
mold or it destroys the stand and breaks
up all the details in the other case it
was worth a shot and we learned
something about the process and now I’ve
got a $60 copper paperweight I can go
throw on my shelf if you’ve ever tried
green sand casting with copper and had
success with intricate molds leave your
comments down below I’d love to connect
with you and see how to get this to work
until the next video thanks for joining
for this experiment guys I’ll be looking
for in the next one talk to you then
just around them thought here we could
probably drill these pieces out and
clean out with a file I might work
[Music]
you’ll put your crucible in water hey
guys thanks for watching and remember
I’m giving away prizes now on every new
