The Flamethrower

[THErAPIST]

OK. On the last rorta I made a thread quite similar to this. I was keeping track pictorially of my quest to build a flame thrower. Well after rorta went down I ran into a little bit of trouble finding parts, and then I just got lazy and forgot about the project for a while. Now that rorta is back up and running though, and since I have a renewed sourch of pieces and parts, I'm on the project path again, and I don't intend to let anything stop me this time.

I'm going to take this time to say that if Rorta goes down again, then damnit I'm just going to have to burn some fucker with this thing when I get it done! Stone, Docta... Don't let the site go down... please? heh.

At this moment I have a pressure washer handle that can handle up to 5000 PSI, and I have a fire extinguisher that I was planning on using as a fuel tank. With that said, I've been doing some hard thinking about my choice of a fuel tank. The fire extinguisher, while having a large amount of volume inside it, it has extremely thin walls. The extinguisher can handle up to 200 PSI, and while I wouldn't want to run the tank on any more than 150 PSI of pressure, I don't want any sort of pressure spike to kill it. Also since the tank has thin walls it would be a very fickle deal to put a valve and a stem in the side of the tank.. So fuck it. The extinguisher is no longer part of the plan.

Recently I became friends with a few of the guys at the local fire department. They get me shit, they pull strings for me, I give them firercackers to train with as back draft simulation (as well as the local police department, flash bang simulation), and so I have connections of a sort I guess. Anyway, I'm going to try to get a used oxygen tank from the fire department and use that as the fuel tank. An oxygen tank holds pressure a hell of a lot better, the walls are thicker so I can drill them, tap them, and pit valves in the side better, and its not flat on the top so it doesnt look as retarded. The oxygen tank also has a more standard threading pattern in the top where the regulator goes. Also, since it can handle more pressure, I could pressurize it a bit more and throw a flame that has a bit more range to it :D

The threading pattern may not seem like anything big, but when the tank is going to be inverted with a hose connected where the regulator usually goes, and when the tank is full of a flammable liquid, leaks right there would suck quite badly.

Also, I used to look quite hard for a bag of some sort so that I could put the fuel tank, the pressure tank, and the mapp gas tank used for ignition all in the same bag. The bag had to be perfect, with no extra space so my tanks wouldn't slide around, but it couldn't be too overly tight to crimp hoses and such. Fuck it though, I have a sewing machine now so I'll just make my own god damned back pack!

I don't know how long it'll take, but i'm gonna press the guys at the fire dept to throw one of their old tanks at me instead of cutting it in half and throwing it away.

Good Luck with the project, and no worries. We back up very frequently.

[THErAPIST]

good! backup is awsome :D
no worries on your pat then (like ya were worried to begin with eh? heh

[Douchermann]

What are you gonna use as a fuel? and don't say gasoline, even if you did make a wonderful flamethrower i'll tell you, your not gonna get the gas to burn long enough to make even a 5ft flame. I can create a 3+ ft flame with a mister bottle (turned on long distance spray, instead of mist) filled with gasoline.

[THErAPIST]

I wouldn't get it to make a flame that was 5 feet long? When it's spraying in a stream that's half a centimeter to a centimeter wide it'll make a pretty long flame...

I was actually planning on using methyl alcohol with a healthy dose of copper chloride so that it made green/ blue flames. Diesel was another though, and so was gasoline. And I guess it could go without saying that I've thought about mixtures of the two latter fuels.

[Douchermann]

The methanol is a better idea, maybe gas + oil would work.

[THErAPIST]

oh, gasoline on it's own works. I've seen video of it. Oil just cuts the amount of gasoline used, it makes it a bit thicker so that it holds a stream better. And it sticks to targets better. Oil/ gasolina misture is the most economical way to go, which if I use gasoline at all, that's what i'll be doing. I just like the idea of colored flames though. Green, brue, red, and yellow... That's the kinda stuff i wanna mess with. :D

[Adrian_Faythe]

Green/blue flames would be tits. I'd love to see something of that caliber. Hell, it'd be an honor to be fucking shot by that thing!

[THErAPIST]

lol. it may be an honor, but it'd also be a bitch!

[gbu-36]

Id definatly like to see what you come up with, Im planning on putting two faux machine gun dealeos on the front of my car (doing the whole mad max thing with it ) and would love to have them functional as flamethrowers.

All the stuff Ive personally seen use a portable air compressor, Id Like to see whatcha come up with




(Btw, Isnt a flamethrower a weapon ? )

[THErAPIST]

Eh i'll be using CO2 as the main propulsion for my flame thrower. And believe me, you'll be lovin it when i get it made. :D

A flame thrower are the things used in World War 2 and vietnam. used to take out pillboxes and that sorta thing.

HELL YEAH! for the mad max car thing too, that'd be awsome! I'd LOVE to see pictures of that!!

[I was actually planning on using methyl alcohol with a healthy dose of copper chloride so that it made green/ blue flames.

If I had to die in a horrible, painful, utterly undesirable, and extremely colorful way, this would be it, second only to death by clown orgy.

Do you think methyl alcohol will even hold a stream? It burns pretty quickly, I imagine pressure and added oxygen would just make this faster.

[THErAPIST]

Eh I'm hoping that it would hold a stream. I'm not sure because there isn't nearly as much surface tension with alcohol as there is with water. I'm going to rely on spraying it at high pressure through a brass hose adapter that has a hole diameter of about 1/4th of an inch. I may have to go up to a larger diameter piece so that the stream would go further. If i went up much though the whole "firing" of the thing might not last long as it would empty itself rather fast I'd think

I don't think the fire dept has any tanks that they can't use at the moment so I'm probably going to have to fold and buy one. Argh lol

[gbu-36]

might wanna look around at local farm supply stores for that sur-fire stuff. From what I recall its kinda like napalm.

Just a thought ^-^

[THErAPIST]

what's it used for? If i can't find that particular brand I might be able to find somehting that does the same

[gbu-36]

I recall seing it mentioned in breath of the dragon by ragnar benson, from what I understand its used for heavy duty deicing of farm equipment

[THErAPIST]

ooooooh ok.. yeah that book is rather old. I believe you used to be able to buy surplus chemicals and stuff from farm supply places. alas that is a thing og the past though as i find it hard to even buy a simple bag of potassium nitrate now a day. I've got a few things I could use for a flammable fuel that's kinda jelly-ish though. army manual TM-31-210 improvised munitions has a great many gel flame fuel systems explained in it :D

[Biovore]

You will want to avoid gels like the plauge. After a few shots, you will start to get clogs and intermitent performace. Not to mention more pressure will be required to move a gel, as it has a higher density than an alcohol which will shoot with minimal resistance.

[THErAPIST]

ahh this is true, but ya see alcohols dont stick to things. there are a few free flowing liquids that just stay together better as they go through the air. i wouldnt really use anything that's in any way thick. i mostly want to shoot colored flames anyway thus alcohol mixtures with the addition of different salts will probably be my primary fuel mixture.

[Stone]

Any progress? Pics?

[THErAPIST]

na no progress yet. i've been spending all on my money on my car. i actually just replaced the front rotors and brake pads on it today. ive got to pay for the property tax in a few days too. prividing that nothing breaks, I sould be able to purchase a tank or a regulator on ebay in a few weeks

[THErAPIST]

the county fire department here just gave me an old oxygen tank for use as the fuel tank for my flame thrower.

http://www.experi-mental.org/other-shit/fueltank.jpg

The problem with the fire extinguisher that I was going to use was the fact that the walls of it were so thin that I couldn't drill and tap any holes in the side or bottom. With this can and it's minimum of quarter inch wall thickness, drilling holes and tapping them shouldn't be a problem.

Kind of ironic eh?

[THErAPIST]

lol, just a bit. but those guys are awsome. thyre all about burning shit and blowing it up. sometimes they dont even want to put fires out and they get depressed that they have to heh heh

[duiker]

These must be the bastards!

[DoctaD]

Strike!

[THErAPIST]

that house... looks increadibly similar to the house that torcher and I burned down...

minus the surrounding trees and such heh. but yeah lol firefighters are some twisted sons o' bitches :D

[duiker]

Being a firefighter wouldn't be too bad a job I reckon.

Rapist, you now have a strike in my bad books- for burning down an incredibly beautiful and mysterious house. And you BURNED it?!!

[THErAPIST]

Well it's not exactly like we intended to burn it down.. It just kinda happened. We had actually stayed in the house for 20 minutes after we got done blowing things appart to make sure that nothing was on fire. It wasnt until we walked down the quarter mile road, and then all the way back down it again and 100 yards past the house that I realized that something wasn't right.

It was a pretty cool house though. oh well. The owner was actually glad that we had burned it down. That's why we're not in jail. The owner didn't press charges.

BTW, I don't currently have more than one bad mark? I figured I've offended or pissed everyone here off atleast once. :p

a few pictures of how the house got killed (http://www.experi-mental.org/other-shit/house)

[duiker]

I'm a patient and tolerant person. :) Most of the time anyway.

[EDIT] ... I can't get the head out of my house.. spoonerism heh. I can't get that house out of my head. Just had an end of year youth meeting. Holidays are going to ROCK very much. After a fourty something degree C day, I'm smelly and I want a shower. thanks. I'll be going now.

[THErAPIST]

lol alrighty then

As a note to the lava spitter here, I've found a good backpack for the tank. One of those camel back water backpacks. They're like $30, so I'll either be buying one, or making my own. I've designed some quick release straps for the bag so that in the event that the planets align right and someone has wished death upon me, and the tank catches fire I can quickly pull a tab and the straps on my shoulders will seperate. Thus all I have to do in an emergency is pull on a ring and the bag/ tank will fall from my back to the ground.

Christmas is approaching so I'm unable to spend my small amount of cash on this project at current moment. After christmas I have to get:


(got it) trigger/ handle ....................................~$25 (ebay)
(got it) Tank .................................................~ Free (donated by fire department HAHA)

The bag .................................................. ....~$30?
High pressure chemical resistant hosing.............. ~$20?
A co2 regulator ..............................................~$20
A small blowtorch regulator/ jet tip ....................~$15
A container of mapp gas ..................................~$6
Various metal fittings ......................................~%10?
I've still got to make the barrel .........................~$5
Balls big enough to enable me to strap this to my back and use it :)

[C.R. Ripshit]

This is going to be so fucking awesome!

[duiker]

Are you going to use a test dummy? Like Buster?

[THErAPIST]

for the first time i fire it? na I was planning on just shooting water from it the first few times just to be sure that all connections are good and tight and that sort of thing. Now... Thats not saying that if get a maniquin I won't dress it up to look like a person and then torch it (with sounds of an animal writhing in pain playing in the background) :D

[TheKillingGame]

What ever happened to this project? I'm well aware that this was started long ago but it ended rather abruptly.

Was there an end to the story?

Sorry for resurrecting ancient thread.
