oh yeah
That's stupid
Hey guys I'm the Hacksmith and this is Make it Real
about a year ago my team and I set out to make the world's heaviest Thor's hammer
we took a replica Mjolnir that we bought from the Armour Factory and we filled it
with molten lead. It weighed in at 73 pounds which we thought was the heaviest
replica Thor's hammer in the world but another youtuber called brain Fuu
managed to make a slightly larger one filled with lead that weighed in at 91
pounds regardless ours was pretty awesome and made destroying things super fun
but it's not the heaviest, at least not technically. The only option to make
a replica hammer heavier is to use a material that has a higher density than
lead which has a density of 11.34 centimeters cubed. That material is
tungsten which has a density of 19.3 grams per centimeter cube
that's almost 1.5 times as dense but it's super expensive pure tungsten could
run over $10,000 in the quantity we need. Luckily the video went super viral and
it's actually one of our most viewed videos on the channel so we can justify
spending thousands of dollars on some scrap tungsten to try making the world's
heaviest Thor's hammer plus we're actually making this as a gift for
someone very special, the world's strongest man you might know him as the
mountain from Game of Thrones. Icelandic born half for Hafthor Julius Bjornsson
Is that right?
Has taken the World's Strongest Man title years in a row he
can deadlift over a thousand pounds, benchpress over 500 and even throw a
washing machine 4 meters
We believe or rather hope he'll be able to wield
Mjolnir one-handed just like Thor, after all his nickname is literally Thor
it's no easy task though because it's terribly unbalanced, it requires
tremendous wrist strength that perhaps only Thor would possess. Our goal is to
make the hammer approximately 50 kilograms or around 110 pounds lifting
it would be the equivalent of taking a hundred kilo dumbbell raising it over
your head and chopping one side off. In fact there's a great video on
BrainFoo's channel showing bodybuilders attempting to lift his 91 pound hammer
and no one could hold it with one hand properly.
Well enough talking about it let's get started but first

James: All right is the modified hammer ready?
Ian: Oh Yeah
Sweet
so let's just open it up again and then we can make it the world's
Heaviest Thor hammer
and the general plan is we're going to put as much tungsten
as we can fit inside the hammer and then we're gonna melt down lead to fill in
all the extra space and the goal is to make this thing weigh over a 100 pounds
ideally heavier than Stormbreaker
Ian: yes, so right now where's 10 pounds so we
need to add 90 pounds of tungsten and lead. Tungsten lead soup
So one of our subscribers actually sold us the scrap tungsten and that is his packaging job
I got a better idea, we got the stunt wire system let's lift
it up to the ceiling and then drop it
Should we up the ante and lay it on fire while we're doing this
So we have to do this quickly before the fire catches on to the Kevlar holding it up
Drop!
Yeah!
and that's how you open a box
Alright so we've got our chunks of tungsten now
Just this small piece weighs almost 20 pounds
42.7
Ian: Error
Just over 85 pounds, if we can get these two big pieces and one lead
we should be able to break 100 pounds
we're gonna want to fill this piece to the brim with lead
Ian: To the bandsaw
Alright so while the bandsaw works away on that piece of tungsten I think we should
probably do it the old-fashioned way by hand
Just a sliver
alright 1mm
Is that doing anything
That took about a week of cutting to get all this tungsten chopped up we went
through I think seven or eight bandsaw blades
The tungsten is extremely hard to
cut machine basically you're not supposed to, tungsten is usually
what's used to do the cutting like tungsten carbide bits and all kinds of stuff like that
Ian: Puzzle time
Feeling how heavy those are
I don't know how lead's gonna get into all those little gaps
Feel like it's not gonna work nearly as well as we hope it will
we can cut back to the scene when it doesn't work
Ian: Perfect
We did it!
Ian: Oh heavy
74.5 pounds, so already just the base of the
hammer weighs as much as our lead filled mjolnir
74.5 plus 15.5 so we're up to 90 pounds
The handle and this piece
92.5 pounds
Ian: So if we can get one of these we can get 102.5
Alright so you might be wondering how we're gonna melt down this lead
We're gonna use a lightsaber
Alright that was freaking awesome but I think we should probably just us a stove
Ian: And a flamethrower
and what better way to melt lead than with not a flamethrower
Ian: To the back
So to ensure consistent heat throughout the Thor hammer we're actually heating up the
Pub-g bulletproof frying pan hypothetically the lead should just melt
real nice into all the cracks
James: Starting to melt yet?
This is our boring flamethrower, so as you can see it's a bit more violent
Dave Dave
22.7 pounds
even with just the top filled with lead we're up to 22.7 pounds plus about 75 pounds
which means we're almost at 100 pounds
James: No no no no no
the bottom cap of the Thor hammer separated and now it's leaking molten lead through the metal dust
Good thing we have an extra hammer
James: we're gonna have like 125 - 130 pounds
damnit
we can cut back to the scene when it doesn't work
the first melting of lead
into the Thor's hammer didn't go so well and it kind of dumped lead everywhere
and destroyed this hammer so to make this not happen with the next hammer
which is the last one that we have, we are going to intentionally melt this one
to figure out what the melting point is to prevent this from happening again
because we were heating up to the Thor hammer on a propane burner we weren't
actually able to control the temperature so we actually got it probably hotter
than the melting point of lead and the actual hammer itself so what we're gonna
do this time is we've actually gone and we've bought a stove for 20 bucks off
Craigslist and that means we're gonna be able to preheat the entire thing to
around 500 Fahrenheit which is still well below the melting point of lead
which is around 625 Fahrenheit so hopefully we get this hot enough that
when we poured the liquid lead in if flows fills all the gaps and doesn't
melt the outside but who knows what will actually happen
By the way let's get started
Okay so the general idea here is we've got a nice big cast-iron frying pan
now what we're going to do is we're going to surround it with iron filings
this way we can get a consistent heat mass around it
that's heavy
I don't think any of us possess the strength just go and slide it in we've
actually set up a chain hoist from the ceiling and we'll actually be lifting it up
let's get this frying pan in there
Time to start cooking
You need to melt down some lead
Now that the hammer is hopefully up to about 500 Fahrenheit
We've actually got a thermal camera
which you can come see right here
Alright let's turn the burner on
That heats up real fast
Alright let's throw the lead on
You can literally see the heat starting to seep through the fan
it looks like the lead is around 70 degrees Celsius at the moment
This is a lot easier than what we were doing before
Woah
Dave: Fire
Ian: It's pretty molten now
James: So what we have to do here is quickly remove the hammer
place it onto this concrete over here and then hopefully we're gonna be able to
pour all that lead in and let it cool down
oh yeah look at that
Ian: so we probably put 15 pounds in
okay we gotta cool this down. Did someone say they were the Hacksmith's biggest fan?
91.2 pounds
114 pounds exactly
51.7 kilos
As far as I know that is the heaviest Thor's hammer
There were two little bubbles formed on the outside
here and here we're hopefully gonna be able to sand them down
Like a charm Ian
Tighten her up
oh yeah look at that
Is that good?
Oh my god
Now all we have to do is polish up the hammer
Put the leather back on the handle and I think we'll call it a day
and then we're gonna use threadlock to make sure that it does not come apart
There's gonna be some very strong people trying to swing this around
James: all right now to make this hammer truly unique for Thor we're also gonna engrave an inscription on it
Which is no easy task, we're gonna have to somehow load this
into the CNC machine
That was difficult
I think it's heavy enough but I'm going to clamp it down just in case
James: Is this gonna be able to move it
Ian: I think so
James: try jogging
Ian: We're going to be using this new engraver that we got from Tormach
it's a spring-loaded tungsten tip and we drag it along and scratches in the engraving
Whosoever holds this hammer if he be worthy shall possess the power of Hafthor
all right we're done, we've created the world's heaviest one-to-one scale
replica Mjolnir, filled with tungsten. We've got our regular replica which
weighs about 10 pounds, we've got our lead filled one which weighs 73 pounds
let's see how much the tungsten one weighs. 114. 4 pounds
that's over 50 kilograms, now that might actually be a bit hard for
you guys to imagine so we're gonna bring out some actual Olympic weights to show
you what that actually weighs.
This is the same as this
You'd actually have to
add an entire other 45 pound plate to get to the same weight is this
Riley?
Riley: Oh my god
Riley: Ouch
James: Perfect
Tungsten has a density almost four times as much as steel, which is insane
Let's see who's heavier Jordie or Thor's hammer
3, 2, 1
We're gonna have each team member here at Hacksmith try and pick up each of these hammers to
see if they're worthy and if so at which level of Thor are they
one two three
Evan: Level 1
James: Easy
Level 2
James: Easy
James: Doesn't that one feel light now?
Ian: I know
James: Nice
James: If you drop it you're fired
Ya
Riley: Oh my god, that is so unreasonable
I can't get it above like here
James: ammonium nitride
Thanks Jujimufu
I almost fell over
Oh boy that was close
I made that way further than I thought I would
I need more
Oh yeah
Ok if I got that far the Mountain can definitely do it
Where do I go from here
