flamethrowers

[ALENGOSVIG1]

Does anyone have any information regarding home made flamethrowers?

[Agent Blak]

There is a Copy of Dragons Breath(Ragnar Benson) floating around here somewhere.

[ALENGOSVIG1]

yeah, i was wondering where i could get that..any one know??

[NightStalker]

I know how to make a flamethrower that will work good and be as safe as possible for such a homemade device...

There are 2 things needed:
- a fire distinguisher (don't know how it is spelled)
- dry ice

You open the distuinguisher remove all of its contents an clean it very well..
to the tubing that normally sprays out the content you attach a piece of metal pipe, about 10 cm long. Be sure you get a fire distinguisher where the "trigger" is mounted near the nozzle not on top of the casing cause this has several disadvantages namely you can't use it without holding the (very heavy) thing in your hand and the tubing will not be sealed when you stop using the device...
then you remove the trigger/nozzle device and push some steel wool into the tubing.
This will prevent flames going back into your fuel depot and blowing it up...
to the primarily attached metal pipe you now attach an ignition device (pencil torch, bigger torch).
your flamer is now ready for use...
Filling and using:
fill in your fuel to till the casing is toally filled. THIS IS IMPORTANT cause you don't wanna have any air in it that could form explosive gases...
now fill in the dry ice and close the device.
you will loos some of the fuel that will be pushed out while filling in the DI and closing but this is not important...

Now to use it just light your ignition device and pull the trigger... I had about 15 metres of flame with the one i built.
But i tried it only once, so something totally different could happen...

Be sure not to fill it before you wanna use it cause your fuel could attack the plastic parts like vents and so on and also open and clean it directly after you used it...

BE FUCKING CAREFULL IF THIS THING EXPLODES NEAR YOU YOU ARE DEFINETLY DEAD OR BURNED HEAVILY...
I wouldn't ever tell someone to make such a device cause it is too unsafe although i mentioned many things that improve savety to a point where it is not likely to blow up...
but it is alway possible that such things happen....

[ALENGOSVIG1]

ok..so where do you put the dry ice?...in the fuel?

this one isnt hard at all...just get some kind of container that can be opened and resealed airtight (i was thinking possibly a 5 pound co2 cylinder but i dont know if it is possible to put liquid in it) and fill it 3/4 with kerosene and then pressurize it with a small co2 tank for a paintball gun. hook it up to a hose with a "t" in it and have one line go to an always on ignitor that goes in front of a second trigger/nozzle assembly that the 2nd line goes to.

the kerosene is always lit in the ignitor and when you squeeze the trigger, it shoots pressurized kero through a nozzle that projects it into a fine stream through the ignitor....effectivly lighting it.

the ignitor would have to be under lower pressure than the trigger assembly and some sort of flashback arrestor would be needed...

********************************************

oh yah...i just remembered that at the old forum...somebody had taken a can of wd-40 and put one of those spray paint can triggers on it and taped a pocket torch in front of the can. if i remember from the pictures right, it produced a nice size flame. however wd-40 reeks when it burns due to the oil.

[This message has been edited by Ctrl_C (edited January 03, 2001).]

[Edd]

no, that wasn't the old forum, that was the film arachnaphobia...........seriously, a spray can? that's not a flame thrower!

[Ctrl_C]

its good enough for his purposes.....plus a hell of a lot easier

[ALENGOSVIG1]

what are some fuels that i could use?..im thinking mabe a very thin napalm but i think you would have to clean the gun after or else it would dry and clog it up..mabe a 50:50 petrol, oil/kerosine?.
i wounder it if would be possible to pressurize the tank with a flammible gas like butane..or would it be too riskt if the tank pressure got too low..mabe attach a pressure gauge? input please!

[BoB-]

The $5 pocket dragon, I forget who posted it (short-term memory loss from newyears http://theforum.virtualave.net/ubb/smilies/cwm32.gif )
It was Starter fluid (which is primarilly Ether) with a spray-paint trigger sprayer attached and a matchbook pull ignitor taped in the line of spray.

[Ctrl_C]

yeah....the Pocket Dragon thats it.

ALENGOSVIG1: i would recommend straight kero because anything more volatile may flash back into the tank and just ruin your whole day

[NightStalker]

you fill in the dry ice into the fuel cause it evaporates directly to co2 making a constant pressure....
NEVER use flamable gases... it would explode as soon as the fuel isn't running constantly through the line...

I made the pocket dragon. It's not really a new idea but I did make some improvements.

The flame is about 8 feet long in this picture. More than enough to incinerate someone in a room or hallway.

If you ask me, I'd attach an Aim'n'Flame or better yet a soldering torch to the end of that. The torches are nice because they're windproof, but the Aim'n'Flame has a nice long nose so your fingers don't get anywhere near the flame.

Ahh flame throwers. Here is something i can add some interesting info about. Bear with me however, because i dont have a scanner, or digital camera, so you'll have to pay attention to know what the hell i'm talking about.

Most parts for my flame thrower are machined from stainless steel, however a well stocked plumbing store will probably give you enough parts to make one. Ok where to start.

First what i used for my propellant was a propane tank for a brazing torch. You know those disposable blue canisters that cost about 2 or 3 dollars at home depot. I had originally intended for this to lay down horizontally, as the gun i was making was meant to be held in one hand, with the guts overlapping my forearm. Similar to a galico subgun. Needless to say, the gas didnt flow properly with the tank laying at that angle (not for long anyhow). I switched to a smaller propane tank used for coleman lanterns (same brand tank), its slightly wider, but much shorter, and this i mounted threads down (upside down). From the tank, I made an expansion chamber that has corogations on it to make the liquid propane expand quicker (corrugations dissipate more heat, or cold as it were). This is simply to increase the pressure that i am getting out of the small tanks. From there, the main line breaks off into a "Y" shape. I have a small feed that goes to the front of the gun for a constant flame to light my fuel as it exits the barrel. This is set up with a simple ball valve so i can adjust, and shut off the flame. Its a lousy flame, similar to a zippo with an orange flame, and a bit of carbon (not enough oxygen i know). It blows out occasionally.. but works ok for now. Back to the main line, after another valve to shut off the propane, i have my fuel cylender. This is also machined from stainless steel, but a large piece of pipe if threaded would work fine as well. The main line from the propane comes into the cap on my fuel tank, with another purge valve on the side. I know lots of valves.. but they are neccesary, i'll explain. When the tank is filled (i use gasoline) you can not possibly get all the air out of the tank. So i dont try to. I simply fill the tank about 80% full, cap it, (point the gun barrel down) then open the valve to my propane tank to pressurize the fuel cylender, then open the purge valve on the side of the tank to bleed off some of the gas. I leave the purge valve open for a few seconds so that it will hopefully replace all of the air in the tank with propane. I'm still here, and not in a burn ward, or grave, so you know it works. At the other end of my fuel cell is where the barrel starts. Its fairly short, only four inches, and threaded into the bottom of the fuel tank. The nozzel on the end of the barrel is just a zerk fitting, i just grinded the tip of it, until it freed the ball and spring, and pulled those out. Right behind the nozzel is my trigger valve. Its a simple lever type ball valve, that i have rigged up to a makeshift trigger. It has a spring return on it to close when i have released the trigger. The flame beyond the nozzel is set about two inches in front of the nozzel, and about an inch low. It flexible tubing.. and easy to adjust.

Now for the problems i have found. First off. The whole thing as i said is mounted in line to fit onto your forearm. The only way i have been able to control it is to strap it to my arm. Now as you can see.. if something goes wrong... you cant exactly drop it in a hurry. Secondly.. when full it weighs about 25 pounds. Not exactly a light weight. Third the trigger pull is about 10 pounds (enough to make the federal government happy). Fourth even with the expansion chamber to up the pressure on the gun.. it only gives me about 35 - 40 feet of flame. I have tried different nozzels, and thickening the gasoline.. but 35 - 40 is the best i can seem to get. Fifth and last.... with the 35 - 40 feet, which isnt all that bad, i only have about 4 seconds of fuel. Sorry should have put this before, the fuel cell holds about 1 liter.

Maybe i'll build a back pack model next.
I'll also try and draw this up, or get some pictures scanned to add.

[Agent Blak]

I saw a guy's web site that had plans like that for sale. That sounds like good design but you could improve it buy adding a simple torch head and maybe a Cricket igniter(Static Spark).

I think I should just add that people seem to be affraid of flamthrowers exploding on them. Unless their is air in the fuel line then theor is no danger of a flash back. Even if the flame does flash back into the tank, the tank won't explode unless their is perfect fuel/air ratio in there. Even if this mixture exists, the pressure generated by the combustion wouldn't be enough to explode the tank - think spudgun.

Another old favourite is the "petrol in a super-soaker" shame the gun dissolves after a while. In which case you could use soemthing like an alcohol.

[NightStalker]

I had one of those superspoaker things exploding in a remote-fired test dry...
fuel was kerosene/gas mix..
Now you understand why i have a lot of respect for those things???

------------------
Death stalks silently....

[SofaKing]

I did the starter fluid thing, really fun I think it's that exact same brand as the picture. I also did the super soaker thing worked well but fused the gun together.

------------------
"ARE YOUR PAPERS IN ORDER" -- Jack Booted Thug

[Anthony]

How do you mean "explode"? I mean is if it leaks/ruptures and catches fire then it hasn't exploded. But if it goes "Ka-fucking-boooooooooom!" they'd I'd say it actually exploded!

I agree that certianly these things demand respect, but I think that being sprayed with fuel from a leak is the biggest danger.

[vehemt]

Naptha would work in a super soaker, but it would make the flexible tubing inside brittle.

[ALENGOSVIG1]

nbk: can u post the plans for that lil frame thrower please?

------------------

[vehemt]

ALENGOSVIG1: it is just an ether starting fluid can with a spray paint handle attached. A match book pull ignitor has been added also.

[BoB-]

Theoretically, if there is absolutly any amount of liquid fuel in your chamber, then the F/O ratio would be way under the ignition point,
*BUT!* the chamber may become heated causing the gas's inside to expand beyond the chambers pressure rating...in other words, boom.

The people that make WD-40 got wind of a manufacturing flaw allowed people to create massive fireballs with there product, they since changed the propellant and the valve design,
the people that make aerosol products are liable for EVERYTHING there customers do with there product, I'm sure most name-brand manufactuers are very careful in there design's.

[NightStalker]

My one actually exploded...
it made ka-Fucking-BOOM the tank was shattered and burnig fuel was spit around...
I still don't know how this happened but it did...
Probably it was cause the fuel slowly dissolves the tank and so weakens it...
And as it is a super soaker you pump air in so you get a compressed explosive mixture of gases that can explode..

------------------
Death stalks silently....

[BoB-]

Sounds like you got a simple pressure bottle explosion.

[Agent Blak]

The CO2 is A Great Idea Because if the flame does Follow it back in to the Tank the CO2 will Smuther it be displacing the O2.
Any of you Saw the Pump Sprayer for Paint and Pesticide(or a pump fire extingisher(Sp?)). You would olny have to modify the nozzel so it will shot in more of a stream(Easily done.)

[NightStalker]

yeah, that was the basic idea of using co2...
i thought of those pesticide sprayers too cause i have one at home but i threw this idea away after the super soaker exploding...
(it was a pressure bottle explosion)

------------------
Death stalks silently....

[Agent Blak]

I thought that going from High Preasure to Low Preasure should keep it fairly Cool. Like when you have your BBQ going for awhile and then you touch the tank and it is cold; Condinsation(or frost sometimes) has formed on the outside of the tank.

[Bandit]

Sorry about brining up an old topic but, i was reading badseed's reply and was wonding if anyone could explain the expansion chamber he talks off. Is it just a pipe for the gas to expand or am i missing somthing?


Bandit

[c0deblue]

Bandit: The expansion chamber to which BaDSeed refers simply promotes a higher propane vapor pressure (and flow rate) than would otherwise be possible. To illustrate the problem: At 90 degrees Fahrenheit the vapor pressure of propane is 149.3 psig, whereas at -20 degrees the vapor pressure is only 10.7 psig. High rates of evaporation (as in this application) exert a powerful self cooling effect on the LP reducing its vapor pressure and delivery rate (this is why a CO2 canister gets so cold when rapidly discharged, for example). A separate finned chamber allows an increased surface area for the liquid propane and promotes absorption of heat from the ambient air, thereby reducing the self cooling effect and maintaining a higher pressure and delivery rate. In industrial high flow rate applications (such as propane fueled engines), electrically heated evaporation chambers are commonly used.

[BoB-]

NBK: what I've always liked about your idea is that you could secure a string to the pull-cover, then tie the other end around your shoulder, one handed flamethrower.

[phyrelord]

does anyone have Ragnar Bensons book about flamethrowers? Oh has anyone else seen fix-a-flat burn it fucking rocks, i threw it in a fire and when it exploded it looked like napalm everywhere it was pretty cool. Also silly string makes a nice flamethrower and it sticks on contact. I was watching a clip of a couple sitting down at their wedding when someone sprayed silly string across the candles and POOF, flames everywhere, scared the hell out of the couple

[SofaKing]

Hehe that reminds me of ash (Evil dead 2) and the one handed chainsaw Hail to the king baby ! The can o' flame works pretty well but has a short range, the best fuels being starter fluid, and carb cleaner. A ineresting common fuel is bakers joy (pam with flour) fairly good for a cooking item !

------------------
"ARE YOUR PAPERS IN ORDER" -- Jack Booted Thug

[blackadder]

hey, phyrelord, I saw that video as well.

Some dick sprayed it everywhere, it ignited, but only burnt for half a second, and then went out. No harm was done!

[DaRkDwArF]

I would definatly suggest a refillable water fire extinguisher (one with the repressurizing vavle thats compatable with car tyre inflators) just remove the tubing on it and replace with copper piping, fill it 3/4 with your mix, pressurize it and get a pen blowtorch from your hardware store to attach to the front for an ignitor...

[blackadder]

Hmmm, I wonder how he made that flamethrower? Anyone got any ideas? I'm thinking he pressurised a tank, and when he fired it he releases the pressure valve on both the propane and the tank, oh god, I'll just shutup now.

[richl261]

i dunno...send off for the plans and find out http://theforum.virtualave.net/ubb/smilies/wink.gif

[blackadder]

I know that was a joke, but fucken hell, this guy charges people money for spudgun plans!!! That's bloody ridiculous! There's hundreds of spudgun sites that give the fucken plans for free, but he goes and charges people???!!! Damn, that is just wrong!! Such a mean thing to do, that annoys me immensely!

About the flamethrower, I bet there's plans on the net somewhere, just have to look.

[Agent Blak]

Check out Predetor's site. I for get the Url though. he has some PHAT plans. instead of the Lighter I would use a wind proof torch.

[Anthony]

The flamable liquid is probably held in the PVC pipe and is pressurised by the propane bottle. Probably works just like a water fire extinguisher. I hope he's not using petrol/gasoline since it doesn't go too well with PVC.

[Agent Blak]

using the Propane tank to preasurise it seems like a really bad Idea to me.

[This message has been edited by Agent Blak (edited April 18, 2001).]

[Mick]

you can use an LPG BBQ tank for a flame thrower..

can't give you many details as i never really got a chance to talk with the guy that had it

basicly, all you do is invert the tank(ie. turn it upside down) attach some sort of gun to it with a hose (ie. the gun from a high presssure sprayer - like a gernie) put a small pencil torch on the end of the gun, light the torch, turn the gas on, pull the trigger

one big ass flame thrower...from what i remember, it put out a flame atleast 20-30ft long, and it was really really loud


also, there is very little chance of the flame going back down the gun, because the pressure of the fluid coming out the gun keep the hose from the cylinder void of oxygen - thus it just can't burn back

[green beret]

does anyone have any detailed plans for a flame thrower that they would like to put up for download??

[YTS]

Just use a normal water extinguiser that has a co2 cartridge fill to thirds or to the water level with fuel of choice attach your choice of ignition ie rag soaked in fuel fixed with lentgh of wire but what ever method it would take a bit of experimentation because if you dont get it right the force of the fuel would put it out .it would also be good for spraying irritants ie ammonia .

[richl261]

YTS..i sort of understand what you are saying..not too clear with the two sentances though http://theforum.virtualave.net/ubb/smilies/smile.gif

blackadder, check out http://www.geocities.com/spudguns_uk/main.html

oooops sorry hehe my mistake http://theforum.virtualave.net/ubb/smilies/wink.gif

[omega1141]

Hi
I'm not sure but does that mean that any pump pressurized sprayer can be powered by Dry Ice without the need for pumping (i.e a supersoaker that you don't need to pump) because with just enough Dry Ice in there it should keep the pressure up?

[Anthony]

Yes, you can pressurise containers with CO2 using dry ice. Just don't put too much on or you've got a dry ice bomb!

[SofaKing]

I have warmed to the idea of using a fire extinquisher to make a flame thrower. But I do not know how to pressurize the tank without using dry ice. One possible method would be to use a number of disposable lighters tweaked so that the gas is leaking then closing it. The main problem would be making sure their is enough pressure, a plus is that the fuel might disslover the plastic casing and make it simpler.

------------------
With Knowledge we find Truth - With Truth we find Freedom

[BoB-]

I used to dream about making bangs by taping down the "handles" on butane lighters and dropping them into wide mouthed 16-oz PET water bottles, 1 lighter would swell the thing to a much larger diameter that will make you *very* nervous, we'd then throw bricks on them to get them to bust very loudly... those are dangerous dreams, not to be attemted.

Butane would pressurize to an extent, but it turns into a liquid at a low pressure (it can be held as a liquid in a plastic lighter) so you wouldnt get much distance.

[omega1141]

I tried making a flamethrower with a pressurised garden sprayer the other night.
I used Dry Ice to pressurise it and had a mix 50/50 Methalated Spirits/Kerosene.
It only shoots about 15ft But it worked pretty well the dry ice overpressurized it at one point and it just started spraying out by its self. But I wouldn't use a flamable gas to pressurize it if I were you because if the flame goes back into the container it wouldn't be pretty, at least wit the Dry Ice the Co2 stops the flame.

[YTS]

SofaKing just use an old water fire extinguisher unscrew the lid which is also the trigger & you will find a large co2 bulb thats what pressurizes it no need for dry ice i have 2 of these extinguishers & you can still buy them as far as i know

[blackadder]

I should reassure you that the flame won't flash back into there if there isn't O₂ present. Even if there was O₂ present, the flame wouldn't be able to burn in there, since that there has to be a PERFECT air fuel mixture in there, for example, if you had butane inside your tank, then, for the tank to explode, you would need to have a mixture of 3-6% butane and 94-97% air.

[Anthony]

In theory if you were using air to pressurise the fuel and the flamethrower ran practically empty, you could get a perfect fuel/air mixture. It probably wouldn't matter if the mix did explode if you were using a water fire extinguisher since they can easily handle the pressure it would generate. It's still worth avoiding though just in case!

[blackadder]

Anthony, what about propelling your fuel with something like butane, so the whole air fuel thing could be eliminated, since there wouldn't be any O₂ present in the system?

[Anthony]

Yeah that would work.

[PYRO500]

that gives me some great ideas! as butane becomes a liquid at low pressures you could purge an enviroment of all air then you could make an arisol propelent flame thrower, I currently have one idea in mind for a flamethrower made using a butane tank, I will draw it up in a few min and post it later

[PcThUg2ooo]

NBK, that is a very nice looking creation. I was wondering if you would have a model number or brand for the attatchment for the top of the can. I have looked far and wide but i dont think they make them here anymore. I am a car resprayer by trade and remember using them a long time ago, i inquired but was not succsessful in finding the required part.

somewhere on the patent database I saw a patent for a self igniting top for any spray can, it had a flash back surpressor and piezoelectric crystal ignitor, it was cool I will try to find it again

[Bob_06]

Water fire extinguisher? Would you be able to get one of these at sutherlands, lowes, or orschelands? Could someone describe one to me? Also does anyone know of a pretty easy to make flame thrower that has no chance of blowing up, leaking, or anything to that extent? It doesn't have to be something a 15 year old drop out could make, just something that you don't have to be a rocket scientist to figure out and to guild. I would also like to know if spray paint nozzles and/or starter fluid nozzles are made to where if you were using them as a flame thrower the flame couldn't go back into the can and blow it up. Thx. -Bob.

P.S. Sorry about spelling. I'm not a good speller or typer.

[Zero]

I just had an evil thought: How about one of those pressure washers you see on the racks at Home Depot? I'm not sure if the thing would blow itself out, though. If it does, just drop a match on whatever you sprayed with fuel...

~Zero the Inestimable

[PYRO500]

hey, you know those shaving cream gel containers that spray the foam a few feet, well, what it you disect an arisol can somehow, drill a hole in the bottom and insert a schrader valve in there, then pull it into place, and to fill it remove the valve core and pressurize with a bike pump, these should shoot a long stream with the cap provided or even better do this wih one of those huge hair spray cans, with the shaving gel top it should spray in a liquid.
I am thinking about doing this and making a simple circuit to make an ignition spark so it wraps around the can and will burn instantly without a visible pilot flame

[-Colza-]

I found the website for a wholesaler of the cangun (as in how many do you want per year), any one know a retailer site? I dont think you get them here in NZ. If so buggered if I can find one!

not a true flame thower but in a sence yes. my friend and i did th ol' "gas in front of potato with burning stick in front of the barrel". works rather well if you want to make a 10x10 ball of flame for about 2 seconds. witch is a long time when it comes to massive balls of fire.

[richl261]

does anyone know what the "can gun" is called in england? i looked on www.homebase.co.uk (http://www.homebase.co.uk) but i couldnt find it... ill have to look around small garage shops then!

[Anthony]

It's the EXACT same as the ones in the US, I think it was homebase I saw it in, looking for stuff on those kind of websites is pointless as stores never have the same stock (or the site is just plain useless).

No one seemed too interested in the design, so I didn't waste my time by drawing schematics.

And at the moment, I am working on a marketable weapon system. If I can get a couple bugs out, and get a patent for it, it could be worth quite a bit to the military, or police.

Which do you think should take the priority here? Something that can make a shitload of money? Or wasting time on something else, that no one showed much interest in?

By the way, I also don't have a website to upload pictures to anyhow. And i'm not going to waste even more time in getting one.

Anyone tried making a little shotgun type of thing and converting the shells into little napthalene charges? Not quite the same, but it could also be fun. Just a tip for anyone who likes napthalene charges: mononitronapthalene ignites more easily. Or you could use a little bag of petrol in the shell instead.

[twinkle]

they use a mixture with oil so when you ejected it stays more a liquid when you would use only gasoline this would vaporize directly into gas also the nozzle is important there are commercial sold nozzles
they have all kind of shapes like in sprinkler installations making screens but also in beam form probably they are using something like it

Yesterday I got bored with the conventonal can gun pocket dragon design so I decided to rip apart my el-cheapo 15$ stun gun that feels like a tens unit. I designed the decive relitively quickly with rubber bands and duct tape holding it together, although tomorrow I hope it'll be hotglue <img border="0" title="" alt="[Wink]" src="wink.gif" /> The device was very simple to produce and is nothing more than a momentary push button behind the triger that can be adjustable via nut and the stun gun transformer and pulsing circuit atached to the top of the can gun. For the spark gap for now it's just some pins rubber banded to the side of the front of the can gun bent inwards. The device is very rugged for it's looks and I'd feel confident of it working if I were to trow it in a box for a while or put it in my pocket it would still be firable. to save battery life (and safety!) I designed the switch to only go off when the trigger is squeezed very hard against the can. I left the safety switch on there as well as I don't wanna get jolted while working on it, I tried to fit the internals inside the device but even with the internal snap connectors removed there wasn't enough room. I hope to eventually get this so rugged that you could throw it relitively hard against the ground and still have it work. here are the pics sorry for the quality but these were the cream of the crop (don't buy ixla cameras!)

You should crop the pictures down to size, I mean is there any relative information about us seeing your arm/surrounding area? But other than that, how long did it take you to put together?

[PYRO500]

I'll crop them, as soon as I find my photoshop disk. it took me about two hours of soldering and de soldering and cutting to fugure out there was no way I was going to fit it inside the gun If I were to redo this I could build one in about 15 min.

[ALENGOSVIG1]

Ah i also had success using electrical ignition for pocket dragons. I simply used bbq ignitor :)

I just recently hot glued the thing together (magic stuff) and changed the battery for better faster sparks. I also built a new refillable arisol can out of a relitivly small hairspray can that sprayed water in a very good mist. unfortunately the epoxy cracked and I am currently letting the epoxy seal dry. I plan on using BBq grill lighter fluid (mostly kerosene) for it it should look very nice and give an nice hot flame with black smoke :) when I finish the can I will try to take some video so expect some video when I finish this, also I added a safety where the hammer drop on a real gun would be, it is a simple slide switch witch was the original safety with the top of the switch that was on the outside of the stun gun. it works really nice and if I keep squeezing the trigger the full way I get the flame closer to the grip than if I were to simply let the flame keep the stuff lit by itself. when the battery runs low it pulses kind of slow and the flame will roar at every pulse causing the fireball to expand slightly witch is kind of fun yet scary I have some pictures below that I just took these are slightly better than the first ones.

Here's a shot showing the left side of the gun witch has nothing on it except a stripe of tape holding the battery onto the other side you can also se the needle spark gap witch can be bent for diffrent types of can sprays for least interference with the spray.

Here is a shot of the back of the gun, you can see the original electrodes of the stun gu with wire attached to them (necessary as a safety gap to avoid damage wshould the spark be blocked (internal arcing in the transformer can destroy it))

Here is a shot of the top showing the circuit board from the stun gun and the HV transformer (the big round thig) that steps up the voltage.

Here is a photo of the top of the gun that shows the arcing at the tip of the needles although it looks like one of the stun gun's orignal electrodes is arcing, it isn't it is far away from the needles and ins simply in the foreground

If you don't care about size two much, take a look at the fertilizer sprayers. I got one with a half-gallon tank so it's pretty small. I also got the brass replacement spraying rod for fear of the plastic one melting once it caught fire. I mostly use gasoline but I need to try something with a faster burn rate, because the gasoline comes out too fast and the whole stream doesn't burn (the end). For ignition right now, I just have a piece of copper wire attached to the spray rod that holds a rag soaked in naptha or gas. I've never had any kind of problem with flash back. The spray rod caught on fire many times and the flame was right where it comes out. For the aerosol can idea- try to convert one of those bee nest sprayer things- those suckers shoot a good 20 feet! :D

[MrSamosa]

Rammstein are bloody crazy. They must have 10 different types of flamethrowers and 20 other pyrotechnic-related tricks they do... Then there's the dildo w/ the hose attatched, but I won't get into that.

Anyhow, I work at a gas station for a bit of extra money. I'm not really a formal employee, just the manager's son...so I'm payed out of his pocket.

This post got me thinking. Over here, we have plenty of old pump handles, gas line, nozzles, etc. Do you suppose that a pump handle would make a good part for a flamethrower? As the part that sprays the fuel (i'm not sure what it's called). I doubt it would have enough pressure behind it, but I'm sure a few modifications could fix this problem. Also, as a flash-back arrester, we sell something called "pipe screen" that are used for tobacco pipes. They cost about $1.60 USD. What they are are little stainless-steel screens. Perhaps you've seen them. The thing is, I'm not sure if the holes in them would be small enough to serve as a flametrap; but if they are, that's a great way to find one.

Gasline. This is perfect for a flamethrower to attatch the fuel-supply to the actual gun. I think this is the best line to use.

As far as the little fire that goes in the front of the flamethrower to ignite the fuel...here's how the United States military did it. You know how a gas stove works? Where you turn it so far and it makes little sparks and then you turn it some more to let the gas in? It's the same concept. What you would do is have a cylindar of butaine with a gas line or propaine-stove style line connecting it to the flamethrower's nozzle. At the nozzle would be a spark plug.

The flamethrower-gun itself would have 2 triggers: One that makes the spark plug spark (use 2 "D" sized batteries, I think), and one to shoot the fuel.

What this does is when you turn on the butaine, you light it with the sparkplug. The butaine will sustain the flame and keep it in a perfect position: right in front of the fuel-nozzle. This avoids having to light a stick or a burning rag to keep in front of the gun.

I hope this post was helpful and I haven't been repeating old knowledge. I've been lurking around this forum for a while and went through this entire thread a few times before, but I'm on a free AOL connection I installed on the computer here...i don't want to waste my minutes <img border="0" title="" alt="[Wink]" src="wink.gif" /> .

[A-BOMB]

You are wrong, the US's flamerthroghers use flare cartiges that last just long anothe to ignite the fuel jet. Though it does use a battery a 26.5 volt if I remember my manuals corretly.

[Fl4PP4W0k]

arrr... I'm pretty sure that 2 D-Cell batteries wouldnt QUITE be up to the task of making a spark gap. 3v at that low power? Me no think so.

Just use a system similar to PYRO500, or if you dont mind wasting a bit of gas, have a wind-proof pilot light continuously running (a small flame nozzle like those used on cheap butane windproof lighters).

If you want to make a flamethrower for damaging things\killing beesnests or whatever, a jet of flame is pretty poor. What you want is a stream of Napalm :D

For example... Say an intruder enters your house? You do not want him to be there. You decide on charring him with a jet of gas. This may slow him down a little, but hell be even more pissed off.

What I propose, is a can of propane\butane that pressurizes a small 1L or so tank of gooey napalm. Not overly thick... the shit you make with polystyrene and gas is fine. Anyway... the container for the napalm would need to be metal... as petrol tends to melt most plastics :p Basically... Have the propane continuously pressurizing the bottle of napalm (roughly 75psi) and have a simple braided hose and ball valve - or one of those gas pump handles - at the muzzle end. Onto there would be a pilot light or spark gap...

Im just thinking that something like that would be MUCH more fun.. and Vietnam-esque :mad:

l8r,
rob

[PYRO500]

While Napalm may work well as a weapon in a war torn landscape with nothing you care about saving, most situations differ from that in that you don't need splashing gooey napalm splashing around in all directions burning down anything it touches now do you?

[nbk2000]

Intruder in house...spray with liter of napalm and ignite...burn down house and everything in it...pyrrhic victory is yours!

:rolleyes:

[Fl4PP4W0k]

bad example... I admit.

Fine... How about street riots?
Napalm would be good in an area like that...

Hey guys check this out- <a href="http://www.jcwhitney.com/product.jhtml?CATID=4892&BQ=jcw2" target="_blank">http://www.jcwhitney.com/product.jhtml?CATID=4892&BQ=jcw2</a> This is a really nice rechargeable aerosol spray can, if you don't mind the salty price. Even comes with multiple spray heads. All you need is an ignition system. Lowes sells a electronic spark system to replace the BBQ igniter. It's incredibly small and light weight but it costs about $20 US.

[Sparky]

I once read about a flamethrower that used a paints sprayer. You know those ones that run off air compressors. The guy put paint thinner in and lit it with a propane torch I think. This would be really easy if you had an air compressor but it isn't very portable.

[Ron McDonald]

Howstuffworks.com has a FLASH diagram that is very imformative. Propane, and white gas is a near ideal mix. The important part is to test your design before you build a big one on your back.

[KinePak]

what do yall think about using a small say 40-pound sand blaster, its got all necessary shut off valves, it pressurizes the tank, the hose is very strong, then only thing needed to be modified would be the sprayer and some sort of pilot light which wouldnt be a problem, the only thing would be needed is an air compressor, but shit as long as you use a pressurized tank sand blaster then it should work, or hell even try to rig up a way to move a flammable liquid thru a pressure washer, that would shoot a flame about 50 feet. i know most of this might not work, but i am willing to give it a try if yall think it might be able to be done

[ElectricJesus]

I got the idea from this thread (I think) to use a fire extinguisher.

What I did, was replace the seals in the valve (a poppet valve) with fuel-compatible o-rings, and extended the nozzle about a foot and a half with high pressure fuel line supported by a mild steel tube that fit snugly around it, and a bracket to the main body for support. The pilot light was a $10 propane torch duct taped to the side with the flame intersecting the fuel stream. I used the stock fire extinguisher nozzle, as when pressureized to 100psi with shop air (in my garage) it shot the fuel about 30-35 feet.

Pictures can be seen at <a href="http://www.pbase.com/electricjesus" target="_blank">Flamethrower pictures found here.</a>

Another board member(VoD)and I are currently working on a design with a backpack-mounted or shoulder slung 2.5gal stainless steel tank, at a pressure of 130psi. Still pressurizing the tank with air untill proper C02 regulators are aqquired to use paintball cyls to pressureize the tank at 120psi. It's in the build and initial testing/modification phases (sealing any leaks, aesthetics, etc...)

Fuel is gasoline/kerosene or gasoline/diesel.

[xyz]

Kinepak, I wonder what would happen if you took the sandblaster and used Al or Mg powder instead of sand...

[rjche]

The unit I use is a standard couple gallons water type extinguisher that has a 100psi gage on it and a handle with Pull pin safety, flexible hose and well designed nozzle to throw a stream quite a ways.

I refill it with 25% gasoline, 75% diesel and pump it up to 100 psi.

The weapon is to handle gang assaults to the front door.

In use it wets down everyone and they are told that any firearm fired will ignite the vapors and light them all. If it needs being lit, another burst with a lighter at the nozzle sends a large flame out.

Another one tried but not not in use was a 5 gallon propane tank, (the older ones with high flow rate valve). Filled with propane it had the same kind of fire extinguisher nozzle and hose.

To use it was inverted (or you can remove the valve and put a copper tube to the bottom of the tank so it exits liquid till empty) and the valve turned full on. Two ways to use it.

One light the liquid instantly on exit, with any flame. This projects a cone of fire about 3 ft diameter at 15 ft, enough to make the devil himself retreat.

Two, pour the liquid around the vicinity of the attackers. They will typically ha ha you for your thingy don't work. Inform all that the gas is not at explosive concentration and any spark or gunfire will ignite it and implode them all. The blast from this thing after about 30 seconds wait is window shattering to a fair distance. People in it are burn center cases if not landfill. Due to the high pressure and high temp, third degree burns thorough clothing occurs.

Another less drastic one is a stainless steel fire extinguisher same as in the first type above, except the valve must be removed and replaced with a pvc ball and handle quick opening valve and fittings to attach the extinguisher's hose and nozzle to that valve exit.

NO BRASS may be used behind the valve or in the tank.

Fill with ammonia water, stronger the better. This in a few months dissolves brass to a crumbly mess so the warning above. It has to have a pipe from the tank top and valve to the tank bottom, with a v notch in it so it can't jamb the bottom and restrict flow.

This is liberally squirted on attacking ninjas. The ammonia water has zero surface tension so it penetrates armor, or anything except a good CBW suit. The solution burn skin painfully about half minute after reaching it. It makes breathing a pain instantly. Same for eyes, which slam shut from spasm. They can run from it but when they stop it builds up gas around them and incapacitates them.

Such fire extinguishers can be found hanging on walls here and there, and at junk yards sometimes. Notice that the gages on the extinguishers are brass and must be removed or they will eat out and the thing spray you unexpectedly. Put an inner tube type valve fitting on the tank from plumbing supply where they are used on farm water tanks. they have quarter inch pipe threads. Get a stainless steel one, NO BRASS, Not even chromed brass. Then pump it up with a regular tire pump or air supply. Take it to 100 psi to get good effect. Use the extinguisher nozzle for they beat any home made thing.

These weapons can be installed in a home and have piping to take the working fluid out to the front or rear door.

If you use this device against storm troopers you will be called all things bad and if its the FBI a queer, (relic of J hoover style). They will not treat you well. So if going for it go all the way, and do something to all those flaming ninjas or those running in circles singing high C, warbled well. Put em out of their misery. Be kind to them, eventually. Do as they would do to you.

Some pale assed prosecutor may charge you with having a destructive device if they discover these. I claim mine with petrol in them are to set back fires in case of a forrest fire that threatens to over run the home. The ammonia one is to chase off coyotes who will take over the place if not deterred. They ain't all that big, but like piranha they are numerous, and all want a mouthful once the leader attacks. You simply cannot defend against a dozen little critters all munching on appendages, once they attack. Same goes for two legged coyotes.

[ossassin]

Does anyone know of a good flamethrower design that shoots a stream of napalm? Apparently the max range for a hand-held military flamethrower is about 130 yards. Is there a way to get the plans for that? <img border="0" title="" alt="[Wink]" src="wink.gif" /> I think that napalm would be your best option if you needed to use one outside.

[kingspaz]

homemade napalm is too thick. IMO, 50/50 motor oil and petrol would be better.

[stickfigure]

I'm new to your forum and I'm asking an old question that someone asked about two years ago. Does anyone have a copy or photo copies of "Breath of the Dragon" by Ragnar Benson or any Military Flamethrower manuals? Got cash...Will spend. I've just purchased a M2-A2 regulator and I'm looking into powering it with a paintball 40oz. CO2 bottle. I need some direction on what to use for the Gas Tanks. I'm looking at using old scuba tanks with special male adapters welded into the bottom and titanium or stainless tubing for pressure lines on the backpack. The wand will have to be custom built by a machinist friend of mine or by myself. Any schematics or design input would be greatly appreciated, right now I'm just doing research and gathering up parts.

THE JIST
My friend built a flamethrower with a super soaker, mounted to a pumpkin for halloween.
he had a lit mesh at the end of the pump and the tank was filled with rubbing alcohol.
its a really makeshift homemade cheap thrill that can spray from 3 to 6 feet. but coming out of a pumpkin's face when you don't expect it too is pretty cool....

SAFETY ISSUE
my friend almost set his house on fire using it in the garage....so be carefull...and alcohol can spill onto the user...watch out for that....

if you can NEVER JUMP IN A POOL WHEN YOUR ON FIRE....CHLORINE BURNS (fortunately this is not from experience)

[Hang-Man]

Two of my friends got hit with flaming gas, one jumped in the pool and was fine, the other "stopped dropped and rolled" and got third degree burns all over his body and ended up spending months in the hospital.

you don't need to point that out.

if you can NEVER JUMP IN A POOL WHEN YOUR ON FIRE....CHLORINE BURNS (fortunately this is not from experience) WTF?? Who told you that chlorine is flammable? And even if it was (which it's not), chlorinated pool water does only contain it in trace amounts, if it contains elemental chlorine at all.

thank you for pointing out to me that chlorine is NOT flammable!

[Big Al]

I have made a flame thrower out of an old 1970's fire extinguisher (its very heavy 38lbs full) the top unscrews I then pour in my choice of fuel screw then cap back on. I pressurize it via shrader valve. I have drilled and tapped a hold in the tank.

[Setharier]

Anybody have ever tried this? I have an air compressor up to 8 Bars, and an adapter where one can attach red, about 1-litre sized canister where the pressurized air sucks the stuff and pushes it out from the nozzle like hell. WOULD IT BE SUICIDE to fill this canister with gasoline, attach an lighter unit at the muzzle and fire it away? 8 Bars of air and gasoline mixture meets fire, it must be like huge torch. Should I try this tomorrow or just find out something more stright for making suicide..? ;)

[iHME]

I would not recommend this, atlest not while holding it. I'd recommend using some remote control system to fire it. And use still some protective gear.

If it does "blow up" on your face and you don't burn to death please post some pictures to educate people from trying it. When you get from the hospital...

[Alexires]

Setharier - If you used something like Nitrogen then I'd try it, but the whole idea of an air/gasoline mix being ignited then burning back into the container, exploding, and covering you in gas doesn't really do it for me.

Perhaps you could use some kind of pressure exchange, such that the pressure from the air pushes on a plunger, which in turn pushes on the fuel which is squirted out the nozzles at 8 bar to be lit....

[Setharier]

I'll try this someday with remote control system. Short pulses and it might not be pulling back to the chamber. Actually as I said, the canister is attached about 10cm from the nozzle and 5 meters long pressure wire goes to the compressor itself, and liquids are sucked there by the underpressure caused by that flowing air. It does have a change, would not take a risk, but technically I would say I just had a supertorch with neither cutting capability nor flamethrower destructive power.
