Make Your Own Flame Thrower
Like any red-blooded, masculine man of the male gender, I love PVC weaponry. You should too. If the concept of heading on down to the local Home Depot and transforming $100 worth of random pipe bits into a killing machine doesn’t appeal to you, you’re a frikkin' pansy. Also, you’re probably sane and will live significantly longer than I will. Nonetheless you disgust me, and I take comfort in the knowledge that your obituary will be nowhere near as humorous as mine. For those of you who laugh in the face of hypersonic shards of plastic puncturing your spleen, here’s an intimate look at how I’ve kept myself busy for the past week: building a PVC flamethrower.
If you're not interested in the building process, skip to the bottom of the post for the fire.
My flamethrower has two main parts, a gun/hose assembly, and the tank. I made the gun first:

It’s made entirely of parts you can get at your average hardware store. The hose connects to a stop valve, which connects to a short pipe nipple that's tapped directly into the tank.

The tank took a while to make, because I let each set of chemical welds dry before doing the next ones. The ends of the tank are two 90 deg. elbows and two 90 deg. street elbows, welded to make two full 180 deg. "U"s. One side of the tank is a 2' length of 4" sch.40 PVC, the other is a 4"x4"x1.5" T with standard pipe attached to each 4” socket.

Before assembling the parts, I drilled and threaded the two holes I needed in the tank ends: a 1/4" standard pipe hole for the outlet to the hose, and a 1/8" standard pipe hole for the valve that I would use to pressurize the tank. Interesting note: 1/4" and 1/8" pipes have no actual relation to the measurements of distance commonly known as the quarter inch and eighth inch. The holes are actually 7/16" and 11/32" respectively. Hooray for non-metric measurements



Next step: cement one end of the tank:

Then the other:

After the tank dried, I dredged up an old camping backpack to hold it. I cut a hole in the bottom of the pack and screwed the gun/hose assembly into the base of the tank.

Finally, I screwed in the Schrader valve (which I bought from www.spudtech.com, an excellent online retailer for PVC weapons and parts) to complete the tank:

Now the whole rig was ready for some pressure testing. Since I would soon be running the distinct risk of giving myself heat-assisted, deep tissue exfoliation, I was extra-careful to make sure there weren't any leaks. I used up a lot of Teflon tape.

And, after filling the tank with water for a trial run, made sure the cleanout cap was on nice and tight

And, after filling the tank with water for a trial run, made sure the cleanout cap was on nice and tight

No leaks! At this point, I had quite possibly the world's most kick-ass super-soaker.


Of course, I didn't go through all that effort for a damn squirt gun. So I added a pilot light in the form of a blow torch.

Much better! The finished product:



There was only one thing left. Add some fuel (denatured alcohol; PVC is soluble in gasoline)

And TURN UP THE HEAT. I accidentally set my camera to long exposure, so some of the pics look blurry. It worked out well for capturing the flames, though.

Absolutly genious concept!!!! Although, while developing a fortified PVC arsonal safety while being stupid must come into play. even thought the flashpoint of the alchohol in the tanks are too low for an explosion towards the empyer end (when pressure runs out) a simple set of dual check valves between the gun and the tank would prevent any chance of blow back into the tank. Otherwise you are a genious my friend! a true engineer of PVC marvels! |

F*CK
Teaching us how to make a flamethrower?
I can't believe this. Well I guess he'll learn how hose clamps on his little orange fuel pipe HOSE (is it even rated for this type of fuel??) loosen off and spray fuel everwhere. Or maybe how when heated PVC fuel tanks melt and spray highly flammable liquid over your back. Or maybe how pipes can leak when heated. Or maybe how a flame can travel back up his "Nozzle" when the pressure drops. (it's called a check valve, look into it) Those gate valves aren't meant for that kind of use. Heat will fatigue that crappy metal and it will crack (high pressure leaking fuel around a flamethrower is a bad thing).
"I used up a lot of Teflon tape." Too bad Teflon tape dissolves in fuel. (the type he used) Thanks for showing all the kids out there how to kill themselves.
...God, this kid is probably dead already.
F*CK! |

| I could just keep going on and on with this... DO NOT BUILD THIS PIECE OF SHIT!! You will burn to death. |
| DrDelhi68 said: |
| Pod, if you dont have anything intelligent to say, KEEP YOU DUMBASS MOUTH SHUT. First off, The "little orange fuel pipe HOSE " happons to be PEX piping. WHICH IS SPECIFICALY DESIGNED TO WITHSTAND HIGH TEMPERATURES. Its used for sub grade radiant heating systems. 2nd, all the heat is directed far ahead of the pvc tanks, so that rules out the thaught of them melting. Congradulations though on knowing what a check valve is, theres hope for you yet. Third, the fuel he's using is Methanol alchol. WHICH DOSE NOT REACT WITH TEFFLON TAPE. Hell pvc primer and glue IS ALCHOHOL BASED. But mostly i have never seen a BALL VALVE (not a gate valve) crack under pressure or heat (brass just dosent do that bud). Obviously u have never looked under a larger air compressor. Those bad boys hold up to hundreds of psi along with all the heat produced by the compressor its self. Perhaps one should sit and use the thing attached to your neck for something other than supporting your mouth to suck dick. |

hey...i really think you did a great job! i am amazed at the level of understanding and thought you put into this.. i myself would really enjoy having the satisfaction that i created such a thing and as a result i was wondring if we could discuss the more detailed portions of the creation that you have made! i know that a lot of other people have asked for plans and prints, and i bet you are having trouble replying to them all, even some trouble at home! but it would be really nice if you helped me out! please email to dragonspark10@yahoo.com thank you! |

| Amazing..any more descriptive plans available? americanidiot949@yahoo.com if so. damn that thing is sweet. thanks dude. |

OUTSTANDING!!!!!
you're a genius. You obviously had too much time on your hands
but you're still a genius.
Some people on here think it's dangerous. Crossing the street is more
dangerous. No is no way the PVC would get too hot. Some people are morons and extremely NEGATIVE!!
Excellent work Chaff. |

| I wonder if this guy's in prison yet? The FBI has a term for what he created. It's called a weapon of mass destruction (some of you may know the term WMD a little better), and it's a federal crime for a private citizen to create or own one. Of course he looks pretty young, so the 10 year federal prison sentence shouldn't be that much of a concern to him. |

OK, couple of things.
First, this article was copied and pasted from an old forum posting on somethingawful.com. Later on in the forum postings, (but not in the part copied here) the creator mentions to be sure to include a blowback valve (a.k.a. the check valve mentioned earlier in the comments), as well as other various safety measures which should be implemented. So, the creator isn't quite as dumb as he appears from this.
Second, meagain, you have no idea what you're talking about. This device is NOT a WMD, and no one with one iota of common or legal sense would make such a claim. A weapon capable of causing injury to more than one person simultaneously is not automatically a WMD; if that was true, almost every modern weapon would be a WMD, including handguns and grenades. Weapon of mass destruction is a term used to describe a weapon with the capacity to indiscriminately kill massive numbers of people. "Indiscriminately" is the key part of the distinction; an example of a true WMD is a weapon such as a missile or bomb destroying a large building and all who happen to be inside it.
Third, as far as I can find (and I have looked into it), there are no *federal* regulations regarding the construction of a flamethrower. There are, however, state and local regulations restricting the creation and/or use of such devices in practically every state. Still, my point is, it is not a federal crime to make this; but, you probably still will get in legal trouble for actually making this if you get caught.
His design is a lot simpler, but not quite as safe as the design previously used by the US military to make flamethrowers. |

pod and every who doubts the man fuck you when the zombies come then u will wish u made one zombies came for me but burned them undead bitches thanx to him man |

Thousands of farmers use a similar devise, called a weed burner. So the kid was product testing a new model of weed burner.
Call it a weed burner and the harshest thing you could be charges with is disturbing the peace. |
| AF_Amuro said: |
for zombies??? flamethrowers are TERRIBLE for zombies, its not an instant kill, it takes a while, and since zombies do not feel pain, they are walking bonfires of even more death. plus because its limited fuel as well as limited pressure, not a good idea...
Zombie Survival Guide, read it, learn it, memorize it, survive. |

HAHAH HAHA HA HA HAHAHA HAAAAA!!!!
there is nothing more commendable than teaching ill-advised pre-teens how to set shit on fire in interesting and probably self-damaging ways!!! |

| AF_ is right. when fighting zombies, you need high-bore shotguns or fully automatics, these tear them apart really quickly. |
