these cheap paper rockets from a
different project will cruise over 300
feet if you got the right equipment to
get them airborne in this project you’ll
learn how to convert common sprinkler
parts into a powerful and portable
handheld rocket launcher
[Music]
for this project I based my design on
the style of an ak-47 assault rifle I
rounded up these PVC sprinkler parts for
about $45 at a local hardware store to
get started we’ll need to measure some
nine inch lengths of 2-inch PVC pipe and
when those are cut they connect to these
reducing adapters together these will
act as the pressure chambers that power
the rocket launch I’m placing the parts
on my work table in the basic form of
the finished rifle so I can measure
custom lengths of one-inch pipe for the
body I’m happy with a look so let’s cut
a two-foot length of half-inch pipe for
the barrel and commit to this design by
making it permanent purple primer will
go on first to clean the connections and
when they’re dry it’s time to add the
PVC cement when we make our connections
it’s important to use glue on both
components and twist them together to
make sure we get a great seal there’s
going to be a lot of pressure in these
chambers and we don’t want to take any
chances with a bad connection
alright the frame is complete and now we
can focus on adding a pneumatic coupler
to this cap this will allow us to
pressurize our system with an air
compressor the pneumatic coupling is
added by drilling a hole in the top of
the cap and tapping the hole to form
threads that will secure the adapter
airtight next we can drill a hole in the
other cap just big enough for a
momentary switch I’ll shape the bottom
with my belt sander and a rotary tool so
that this trigger cap will fit snug on
the handle I’m getting this ready for
painting so I’ll need to clean off the
stickers with some adhesive remover and
tape over the parts that I don’t want
exposed
we still need to attach the trigger
before we can paint and we also need to
attach on doorbell wire as well as this
poly tubing these together will join the
electrical system to the trigger switch
in the cap to connect them up we’ll have
to cut a hole just bigger than the tube
and while we’re at it let’s drill a hole
in the center of this plug as well
because we’re gonna need that later next
let’s strip our doorbell wire so we can
connect each wire to the switch when
those are in place and tightened we can
secure the switch on the cap then pull
the wires through the bottom hole we
need to get these wires through the
protective
tubing and I found that could be done by
sucking a string through the tube first
then attaching the wires to the string
this way they pull through the tube
easily alright the tube is in place and
we can add some hot glue to help keep it
there and now we’re ready to attach the
trigger to the frame hot glue goes on
the back and it presses into place
nicely I’ll add just a little more glue
to fill in the gaps okay it’s time for a
paint job and I think it’ll be fun to
use a variety of camouflage pants so
I’ll hang this up and start attacking it
with four different colors I’m letting
each layer dry before adding the next
color and just spraying in random
patterns for effect I’ll add a coat of
finish and when it’s dry I think it
looks pretty good the masking tape we
use to cover the trigger switch and
pneumatic coupling can all be removed
and then thread tape can be added to
each of the threaded connector nipples
we need to make sure these are screwed
back on fairly tightly because we don’t
want any air to leak let’s add the
inline sprinkler valve next and then
screw the Barrel on to that the valve
wires get pulled through the 90 degree
joint and the elbow presses nicely onto
the solenoid casing now it’s time to rig
up the electrical system the ends of
each wire need to be snipped to size and
strip to expose the bare copper wire the
other side is made ready by pushing the
poly tube through the hole in the end
plug that we made earlier next we need
to wire a nine volt snap connector in
series with the valve and the switch and
that can be done by twisting the ends
together
I used electrical tape to cover the
connections and it ends up looking like
this now we can snap our battery in
place and add hot glue to hold the
tubing inside the plug when that’s cool
the wire and battery suck very
comfortably up into the casing to shield
the battery from the elements the system
is finished at this point you should
have your very own ak-47 style
compressed air rocket launcher I’m
really happy with the way it looks and
handles I’ve even made barrel adapters
for shooting paintballs and water
balloons and a valve stem adapter for
hooking up a bike pump for anyone who
doesn’t have an air compressor a little
pose for the camera and I’m ready to
test out one of my five cent
high-pressure paper rockets
look for the video on how to build those
alright all my neighbors are at work and
the streets are clear so it’s time to
fire well where’d it go I actually lost
sight of it but after a few minutes of
searching my little boy helped me find
it way down the street almost 300 feet
away that’s nearly the length of a
football field and it’s still in perfect
condition so let’s shoot it again I’m
firing these at 135 psi and they’re out
of sight every time well this is far
surpassed my expectations not only can
it launch rockets completely out of
sight but it’s portable customizable and
can be modified to launch paintballs and
water balloons hundreds of feet that’s
it for now if you liked this project
perhaps you’ll like some of my others
check them out at the king of random
calm
