Homemade RPG? You betcha!

Remember those fun napalm bombs and smoke grenades we made a few days ago? Well, lets take this one step further!

Jesus might be a douche but he is right on this one- do set a building on fire! But with homemade RPG, you can torch a lot more from a safe distance!
So lets get building!
Basically, we are building a potato cannon. This guide is from HERE. I suggest you visit that site.

I wont give you the full details, how to do everything on this one since you cleary need some knowledge of your own OR you shouldnt do it. Do your research if neccesary.

The materials

There goes the neighbourhood...

Building Materials
-5 feet of 3" ABS (DWV) pipe
-2 feet of 5" ABS pipe
-A 5" to 3" reducer
-A 5" threaded adapter
-A 5" end cap
-A BBQ ignitor (+1 Screw)
-ABS cement

NB! The measurments are estimated- please do measure the soda cans or jars you are going to use.

Consumables
-Cheap aerosol hairspray
-Ammunition (will cover that later in this post)

Tools
-Hacksaw
-Drill

Assembly

Leisure time with friends!

-Cut the 3" pipe to about 13" or a size you prefer (the larger the combustion chamber; the more gas; the more boom)
-Make sure the reducer fits over the pipe
-Spread some ABS cement on the inside of the reducer and outside of one end of the pipe, slide the reducer onto the pipe with a twisting method
-Repeat this for the threaded adapter
-Repeat this for the barrel (5' of 1.5" pipe)

Make sure your gluing is done properly, you dont want it to explode.

Install the ignitor

Drill a hole in the 3" pipe for the metal lead from the ignitor to fit, mount the ignitor using screws provided, you can slop some glue around the hole to make sure there wont be a gap where the flames will shoot out and burn your arm......

In order to create the arc (spark) to ignite the gas, there needs to be a metal contact between the lead from the ignitor and the metal chasis of the ignitor.

If you mounted the ignitor with bolts into the pipe, bend the metal lead to be within 1/4" of the bolt to make a spark,
I however put another screw in from the other side, but had to run a piece of wire from it to the metal chasis.
Both methods will work.

Lets get the fun started!

He wont park on your lawn again, thats for sure!

First, make sure that the cement is cured

Firing:
-Unscrew the end cap
-Force ammo into the barrel

-Spray some hair spray into the 5" pipe (combustion chamber) for 2-3seconds
-Quickly screw the end cap back on
-Point it at a 45 degree angle to maximize range and push the ignitor

Ammo

If you wanna use potatos- be my guest. But you want firestorm, dont you?

Then why dont take a smaller glass jar, some napalm, more styrofoam and a fuse and make a napalm molotov? Also, i reccommend more liquid napalm on this one, or you can use just gasoline or other flammable liquid instead.

Make the fuse long burning, you dont want to kill yourself, do you? I guess you can make a molotov already, so lets skip this step. Oh, and dont forget to add a fuse. 

Make a shell out of styrofoam for the jar, so that it would fit snugly in the barrel. Make it out of two halves, what will drop off after the "rocket" has exited the barrel. I suggest you experiment on that one.
You can also use those soda can smoke grenades with this. Shoot them through windows!

Congrats, if you succeeded, you have a RPG now! You can now take down vehicles and torch houses!

Oh that silly Jesus!

Also, the disclaimer is at the bottom of the page :) have a nice revolution, my children!

Thanks for you, you and YOU! Without your interest i wouldnt be writing these sick posts!
