when in doubt use brute force what’s up
guys welcome back to the shop for part
two of our flamethrower build video you
remember in our last video we took a 20
pound co2 tank a scuba harness and some
other miscellaneous fittings and put it
all together to make a basic
flamethrower assembly in this video
today we’re tying up the loose ends with
a slightly more complicated assembly and
getting this thing ready for action now
once again just want to give a big
shout-out to flame thrower plans comm
they in no way sponsored this video but
it was their idea and made this video
possible today so our flamethrower is
pretty much assemble there’s really only
two things that we need to do left at
this point and that is to take the hose
from our pressure washer and connect it
to the co2 tank then take a propane
torch and mount it underneath the
pressure washer but it’s not nearly as
easy as it sounds because we’re actually
gonna have to do a lot of modifications
to the nozzle itself alright so first
things first let’s jump over to our tank
and drill some holes now I’m gonna be
shooting this thing right handed when
the sticks on my back I want the hose to
connect to the right side right down
here so the first thing I’m going to do
is put the paintball tank across from me
on the opposite side I’m going to take
my left hand go all the way to the
bottom and measure up from the bottom
one inch now that we got our position
mark I’m going to be using a thirty
seven sixty four drill bit to drill in
tap a hole
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
yay success that took far longer than I
was expecting you know it’s really weird
about that is I think we caught it on
the curve there’s like half an inch here
but then it curves in obviously the
bottom is thicker and then the walls are
cuz the top part of the wall here is
only about half an inch thick but then
that back end is like an inch and a half
I’m not sweating at all
[Music]
[Applause]
[Music]
[Applause]
so quick update guys I finally got
through this tank here was a lot more
difficult than I was expecting here’s
why when I drill down into the saloon I
was expecting it to maybe be half an
inch thick but it just kept going and
going and I think the reason is because
the bottom of this tank is actually
sloped on the inside so there’s much
more metal near the bottom and even
though the instructions safe to drill at
the one-inch point just be prepared that
it’s gonna be a lot more work than you
think
we used our thirty seven sixty four-bit
to go in and then I use this 3/8 inch 18
NPT to actually cut some threads so
theoretically the end of our pressure
washer hood should now screw in
perfectly but the problem with drilling
and tapping our own hole is it’s put a
lot of aluminum shavings inside the tank
so actually had to take a pair of
channellocks and a rubber mallet and
knock the top valve loose to open a hole
big enough we could turn the tank upside
down and shake all those shavings out
[Music]
[Applause]
[Music]
so here we are guys it took quite a bit
of work but we now have the hose
attached to the tank few surprises along
the way the tank is very very thick it’s
very difficult to tap this thing and
screwing the hose on only got within
about a quarter of an inch of the tank
itself but there’s quite a bit of pipe
thread tape on there and it’s sealed up
pretty nice and tight so I think it’s
gonna do the job and now we can move on
to adding the propane torch to the
actual flamethrower nozzle itself now
looking at the plans I think this might
be one of the harder two ways to go and
might be a little bit easier to stick
some kind of electric igniter near the
end of the tips as the gas links coming
out it auto ignites with high volts
electricity however I am gonna stay true
to the plans we’re gonna finish this
thing out with a propane torch now the
basic modification we need to make with
the torch itself is actually to bend
this part forward because when it’s
resting up against here you can see the
flame goes straight through the gasoline
we want it to be more in line with the
flow but unfortunately it’s not quite as
easy as just taking this tube and
bending it there are things on the
inside that we need to tweak we also
want to modify the handle so it offsets
about 130 degrees if we can use it more
of the handle for striking the flame on
our flamethrower so we’re gonna get down
here we’re gonna undo the nuts and the
bolts we’re gonna pull out the
electrical cable we’re gonna heat this
thing up with another torch Bend it let
it cool down and then we’re gonna drill
a tap a hole and reassemble everything
and hopefully it works
[Music]
[Applause]
so what I just did is took a little
allen wrench and I ended this set screw
which allowed me to remove the entire
nozzle at that point I unscrewed the tip
and we could see down inside there was a
little green wire which is used to make
the electric spark to actually light off
the propane or the map gas that little
green wire needed to come out so we took
a little elbow bracket pull the cap off
that and then unscrewed it so that we
could push the green wire up through the
top of the nozzle and that’s what we
have now so at this point we’re gonna
make two main modifications to it we’re
gonna heat up this elbow to the point
where we can bend it up a couple of
inches and straighten it out they’re
gonna drill and tap a hole into the side
of the brass so when we put the whole
thing back together it would be offset
to the point where we can start off our
flamethrower with the press of a button
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
[Music]
[Applause]
alright guys so here is where we’re at
with our nozzle we took the other
propane torch we heated this up and then
we used a wrench to bend it over about
two inches or so just so it flattens out
the angle then we located the original
hope for that 90-degree elbow and we
flipped it over about a hundred and
thirty degrees and drilled and tapped a
new hole into the top drilled with a
7/32 inch drill bit and tapped with a
quarter inch f28 I also had a little bit
of heat shrink tubing onto the green
cable itself and that’s just to help
protect it from any scratches and give
it a little bit more thermal insulation
so the last step now is just to rerun
that green wire through everything and
use the new hole for our 90-degree elbow
and we basically put the propane torch
back together
Oh success
[Music]
[Applause]
is actually looking really good
[Music]
[Applause]
[Music]
Oh right-handed oops I think I made it
left-handed well I messed that up so
we’re gonna have to do all over again
[Music]
there you go all fixed
our torts modifications are complete and
I just gotta say word of caution don’t
do what I do when you’re drilling and
tapping the new hole for the 90-degree
elbow make sure you’re drilling it in
the right place when all said and done
you want your torch to be able to sit in
your hand with your middle finger or a
pointer finger on the button there and
the torch angling upward it should look
something like this and just to make
sure the electrical went back together I
took the nozzle off and as you look down
and click it we can actually see the
green wire sparking against the outside
of the tube and clicking it ten times in
a row we see at fire ten times that’s a
pretty good sign so at this point we can
put the nozzle back on screw it onto a
tank of propane and see if it still
lights off all right moment of truth and
pull the trigger if this thing lights
off we should be good
looks like it’s firing off just about
every time so let’s go ahead and strap
it up strapping this propane tank to our
pressure washer is as simple as using
two of these large quick-release bands
[Music]
[Applause]
[Music]
[Applause]
[Music]
there we have it guys you can see I’ve
got the propane tank connected now to
the pressure washer nozzle I just use
two of these bands to show up nice and
tight and I tried to line it up so that
the nozzle and the propane nozzle are in
line with each other and looks like we
did pretty good job now in essence this
is it and just for fun I’m going to
strap this to my back and just get a
feel for how it works but before I
actually use this before I fill it full
of gasoline and diesel I’m gonna do
pressure test with water look for any
leaks and then charge up this co2
container here the basic idea of how the
system works is this big co2 canister
here provides pressure inside the tank
which pushes the gasoline and diesel
mixture through this host of the
pressure washer out the nozzle and into
the flame of the propane torch below and
if this thing does what it claims we
should be able to shoot flames about 50
feet long
[Music]
what’s really nice about this is it’s
very ergonomically placed we got the
propane torch right up here in the left
hand we got the pressure washer in the
right hand and just feels very very
comfortable and to make this thing spray
we just disengage the safety pull the
handle to get the gasoline shooting
ignite the propane torch
and throw some flames so using pressure
washer parts and a co2 tank we’ve been
able to make a flamethrower using
instructions off the Internet and the
next time you see this thing will be in
action putting up the test with diesel
and gasoline thanks for joining me for
this build video I’ll be looking for the
next one talk to you then in case we
haven’t met yet I’m Nate and I’m here
working with Brandt on some awesome new
projects yes I am excited to have Nate
joining us here on the king of random if
you will have him and with any luck
he’ll be seen coming the next video back
to then real quick update guys that came
out here to pressure test the system and
found that I made a few of the
connections a little bit differently
than the instructions suggest down here
to the tank I just had the hose
connected straight to it and what I’ve
done is I’ve taken two of the fittings
and I’ve put a male fitting and then
this Quick Connect adapter so that now
this flamethrower does match the plans
perfectly
