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.

Add a Teacher Note to share how you incorporated it into your lesson.

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.

    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 :)

    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!

    No but i see what your saying, but a little idea with the thought of mortar rounds. Have you ever thought of creating a "Noob Tube". Just a thought.

    Have you seen what a mortar does if you light it on the ground? It hardly moves before exploding. It needs to be in a close fitting tube to launch. If you did this it would probably stay in the tube and explode by your head, or if you are lucky it might roll out of the tube and blow up at your feet.

    When you are firing a self propelled rocket you want to just have a tube with a handle and ignition because if you cap the end, you will absorb the force of the firing, not have it dissipate out the end.

    While that is good for a real launcher, this is designed to fire hobby grade estes model rocket motors. Even the largest E-11 engine is not enough to put any noticable force on you if you were to cap this. Also if you have ever launched a model rocket motor you would know it has a wide area of extremely hot exhaust gasses and sparks, and i would recommend having as much protection as possible from this. I would also advise you add a face shield such as on WWII era tank buster launchers. Or you could just wear goggles and a face mask.

    You are not understanding me, what I meant by "force" was the possible melting/fragmentation of the pipe from the sparks, perhaps I should have worded my statement differently.

    OK, i see what you mean now. There is absolutely no chance of the pipe exploding, but i would not doubt the rockets ability to melt it if it didn't exit quickly enough.
