How To Build A FLAMETHROWER


all these connections went together
beautifully and this system is looking
amazing what’s up guys welcome back to
the shop today we are jumping into some
hardcore DIY for today’s video we’re
gonna be building a flamethrower now in
one of my more recent videos I jumped
out of the comments and found a
suggestion from this anonymous user who
asks grant I know this is crazy but so
are you could you make a flamethrower I
think that sounds like a fantastic idea
so that’s what we’re doing for this
video today this comment got 3385 thumbs
ups that’s absolutely ridiculous so
apparently a lot of you want to see this
so let’s jump right in so in preparing
for this project today I thought rather
than reinvent the wheel why not find
somebody who’s already built a
flamethrower and work with their design
so after a bit of searching on Google I
found this thing how to make a
flamethrower to do-it-yourself manual
perfect right so a little bit context of
this situation I went ahead and
purchased these plans only cost about
$30 and I’ll leave a link in the
description if you want to get them for
yourself there’s about a hundred pages
of detailed information which can be
very overwhelming so the purpose of this
video today is to show you my experience
following these step-by-step
instructions from flamethrower plans
calm by the way this is not a sponsored
video I paid for everything you see here
I just wanted to give credit where
credit’s due
I’m gonna break this tutorial into two
different parts the first one is a
familiarization I’m gonna show you all
the equipment all the parts that you’re
gonna need and the basic assembly in the
second part of this video we’re gonna do
some of the more complicated tasks like
modifying the tank and torch one of the
cool things this guy did in this PDF is
he put Amazon affiliate links to all the
materials you need so I literally just
open up the PDF click all the links and
just order immediately the total cost of
all the materials ended up being right
around 450 dollars plus the $30 for the
plan so all-in-all this is about a five
hundred dollar bill so Amazon delivered
all the parts I got everything together
so let’s take a look at what we got so
starting over here we got a 24 ounce co2
tank like they use for paintball we got
a paintball universal fill adapter we
got a four and a half inch length of
eighth inch metal tubing this is male
NPT and 0.3 20 CGA female two eighth
inch female NPT and that whole assembly
there is going to attach this tank here
in just a few minutes next we’ve got the
assemblies for the pressure washer hose
and handle so start off with a pressure
washer gun and you can see there’s no
nozzle or attachment for the end here
and that’s okay because we’re gonna add
an M 22 male by quarter inch female NPT
a quarter inch male NPT by eighth inch
PML empty
reducer a three-inch length of male
tubing NPT to NPT and 1/8 inch female to
female NPC coupler the hoses three feet
long it’s 4,000 psi rated and it came
with the connectors which screws into
the pressure washer handle itself and
the threaded end connects to the m22
male by quarter inch female adapter this
is a 3/8 inch male quick disconnect this
is a 3/8 inch female disconnect to male
NPT then a female MPT 2 female quick
disconnect and a male quick disconnect
to female NPT coupler other than that
the only accessories we really need are
one and a half millimeter shrink wrap 2
large quick disconnect hose clamps and a
propane torch this is a 20-pound co2
tank it can hold a lot of pressure and
to mount it up on our backs we’re using
a scuba back harness I should also
mention I picked up some of this
plumber’s tape for threading and
connections I usually use white for pipe
threads but in this case we want to go
yellow because yellow specifically
designed for plumbing applications we’ve
got all our parts laid out in order of
assembly you already know what they are
now so let’s go ahead and put them all
together

we got the 24-ounce tank feeding into
the 20 pound tank and next we assemble
the hose
[Music]
we’re also gonna have to get this
harness

check it out guys flamethrower is just
about done all these connections went
together beautifully and this system is
looking amazing I cannot wait to test it
out after going through this process
myself it seems like the hardest thing
really is just getting the right
materials but if you use this guy’s PDF
download from the links he’s already got
on there everything seems to fit
together pretty well there are just a
couple more modifications we need to
make this is where things start getting
a little bit more complicated so I’m
going to show you how to do this in the
next video but essentially we’re gonna
take this hose plug it into the tank and
add a propane torch underneath the
handle here so we have a source of
ignition and of course a big shout-out
to this anonymous user for suggesting we
actually build a flamethrower and
Forgetting over 3000 thumbs ups good job
man and go check your youtube inbox for
saying 25 bucks thanks for joining me
for this project today I’ll be looking
for you the next one talk to you then
like the Stanley Cup hey real quick you
remember this guy this is Nate just
wanted to pop in real quick and let you
know that I’m prototyping some new
projects for the show and looking
forward to joining you here on the king
of random in the very near future see
you then
