Introduction: PVC Rocket Launcher

A few points:

1) This is a rocket launcher without a rocket I will leave it up to the end user to design your own munitions.

2) This device will be considered by many law enforcement agency's as a weapon DO NOT AIM AT ANY THING (other than open sky) I AM NOT LIABLE FOR ANY INJURIES CAUSED BY THE USE OR MISUSE OF THIS DEVICE.

3) I know the title says "PVC" but in the photos the plastic I am using is ABS plastic pipe from the Home Depot.

4) This device is designed to ignite Estes model rocket engines.

5) The launcher costs around 40-50 dollars without the cost of the electronics,wire,etc.

6)I apologize for not taking pictures as this is my first instructable and I had already built this before finding this site.

Step 1: Gather All Materials

Materials:
1.)-4" flange
2.)-4"-2" hookup
1.)-2" end cap
1.)-4" coupler
2.)- 2' sections of 4" ABS pipe
1.)- roll of electrical tape
1.)- X-acto knife or wire strippers
1.)- 9v battery
1.)- Radio Shack toggle switch with safety cover
1.)- Drill w/ bits
1.)- 7' Speaker wire, I used model the rocket launcher's igniter wire
1.)- hacksaw
1.)- 9v battery snap

Step 2: Where to Drill

Drill a hole large enough for the toggle switch on the concave side of one of the hookups and on the convex side drill a hole for the wires to pass through (see badly drawn diagram)connect the wires to the relevant areas(I twisted the wires through the holes in the toggle switch to make the connections).

Step 3: Assembly

After wiring up the electronics in the hookup assemble the piping after cutting one of the 2' pipes in half so that the order of the fittings is (from back to front) flange,2' pipe,shoulder rest hookup,1' pipe, electronics hookup w/ 2" cap on bottom, 1' pipe, coupler.

Step 4: Finish

All you have to do is run the wires to the back of the main tube and connect them to the rocket.


You could use ABS cement to fuse the pieces together but i didn't and it works fine.

    This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.

    See the pictures and never use PVC to hold air, Please.

    Nice! but I think you might want to think about a blast sheid

    I have an idea. I could make this, but instead of launching rockets, it could launch nerf footballs with a paintball CO2 tank as a power source, and you could cut the male end of a remote line off to hook it to a pipe.

    Hey, you may have seen it by now, but there is an "ible" to make an m72-law co2 powered launcher on this site. Just type in co2 m72-law in the search. too lazy to look up the author :)

    That sounds awesome but I can't find it anywhere
    Care to look up the author

    Hey there! Ok, his name is MrTinkererin, and the project can be found in the graphical search under airsoft m72 law. I apologize, my info was incorrect as it is powered by propane in the shell instead of co2. Propanes volume exspanision is greater than that of other comparable pressurized gasses that's why it's used. But he explains that all in his instructable. Happy building!

    Thanks I appreciate it.

    what are you using to draw that, is it a cad?

    looks like CAD lite to me...
