Flame Thrower


— Posted by Optical on 5:01 pm on Feb. 20, 2002

Does anyone know how to make a flame thrower that will have a flame that can shoot atleast 4 feet?


— Posted by jmb1125 on 7:03 pm on Feb. 20, 2002

what size? pocket size, backpack size, in between?


— Posted by Optical on 8:00 pm on Feb. 20, 2002

Both would be nice but it doesnt really matter


— Posted by qube on 8:01 pm on Feb. 20, 2002

Pocket size!!!!??? Fuck never heard of that, depends on power. How could a mini pocket size flame thrower be created?
Most decent flame throwers require a large fuel tank to be carried ina similar way to a backpack on the users back, so if you dont want to be doing that then the flame thrower wont last long.

If I made a packback flame thrower what would I use as the propellant, how would I hook it up and what would you use for the barell?


— Posted by ilovekayla on 8:21 pm on Feb. 20, 2002

well…. You could search online… i once wanted to make one also… so i lloked it up.. but that was years ago… so just go on google and find the plans for one..


— Posted by jmb1125 on 8:24 pm on Feb. 20, 2002

yes qube, pocket size. no plans, never made one,
could be done for a 1-second shot.

Optical, you would need an inert gas. CO2 or simular.


— Posted by Optical on 8:46 pm on Feb. 20, 2002

are you talking about the CO2 as in which they use in paintball guns? would that just propell the propellant or would that be the propellant? When I first had the idea I was goin to use WD-40 as the propellant do you think this would be possible?


— Posted by MrDingelFritz on 9:43 pm on Feb. 20, 2002

or u could somehow atach a sparypaint bottle to a holder kinda thing lite a mach put it on the holder a spay away i mean flame away but bad thing is it would look domb and suck if the flame went out and i just thought of somthen could u make a greanade outa a spray paint bottle by liteing it up and throwing it na it would explode to fast!!??


— Posted by Darkie on 9:45 pm on Feb. 20, 2002

Man, some people need a friggn imagenation!!! Here is my idea for a flame thrower:
Take a couple large jugs(like 3 liters) and make a back pack out of them. Better yet, use your welding skills and make 2 metal ones, cone shaped at both ends. One end(the top) needs an attachment so u can screw on a propane(one of the smaller ones) to it and have a constant feed of propelant. Then run a a hose from one to the other or have them both converge into one hose. Either way have this one hose lead to a “gun”. This can be modified from things like garden hose sprayers and best of all cheap pressure washer sprayers. Then duct tape one of those grill lighters to the end of ur gun. Fill the tanks with gasoline, or napalm, or kerosene or what ever.

Hope this crude design helps to spark( no pun intended) something better.

BTW, sorry about all the typos cause my spelling sucks and the batteries in my cordless keyboard are gettin low.

Lotsa love


— Posted by ilovekayla on 9:51 pm on Feb. 20, 2002

if you used jugs tehn the gas would melt threw them soaking you in gas and booooooooooooooom


— Posted by Darkie on 9:55 pm on Feb. 20, 2002

yea, i figgered pepsi bottles would be a mistake. I was invisioning something like antifreeze bottle for a secnd but u have got to make some metal ones, really not that hard if u have some welding stuff.


— Posted by ilovekayla on 10:01 pm on Feb. 20, 2002

but you also need something keeping the flam from going into the “backpac” what dpo you think you could use for that?


— Posted by jmb1125 on 10:26 pm on Feb. 20, 2002

you need 2 small tanks, CO2 cartridge or whippits nitrous thingies. life vest CO2 are best cuz they screw in.
the CO2 would pressurize the other bottle which would force your flammable liquid out thru a fitting in it’s bottom….then a main valve (trigger)….then a check (1way) valve….lastly a nozzle.

ignition? simple: one of those crackhead pressure torch lighters that they sell in smoke/headshops. mounted right below the nozzle tip, so the flammable liquid has to pass thru it’s flame. a miniture pressure gage would indicate reliable pressure is available.


— Posted by The Great Milenko on 4:42 am on Feb. 21, 2002

hmmm…methinks this should be in the weapons section, seeing as though it doesnt actually explode, or atleast it’s not meant too, but if your dumb enough to make somthing that pressurises fuel, then expells it onto a flame, from materials that i am guessing aren’t meant for that sort of thing, (or maybe theres a do it yourself flamethrower kit at your local toy store)perhaps it should be in this section, but for the moment i’m moving it too the improvised weapons section.


— Posted by Zambosan on 9:50 am on Feb. 21, 2002

Before testing this out, it’s important that you meditate to get yourself into the right frame of mind. Close your eyes, clear your mind, drop trou, sit on your left thumb, and chant “stop, drop, and roll… stop, drop, and roll…” :biggrin:


— Posted by Darkie on 1:11 pm on Feb. 21, 2002

A common misconception is that the flame can be “sucked” back into the tanks or arosol bottle. Remember for anything to burn there must be oxygen present. There will be none in the hose that leads to the tanks. So no, the tanks will not explode. Just make sure the hose doesn’t catch on fire, cause that would be a problem. Also, the CO2 propelent would be fine but i would think the propane would be better cause it is flamable too and more avaiable. Any coments?

Lotsa love(“Let love be the driving force behind all your hate”)


— Posted by fluffy on 1:33 pm on Feb. 21, 2002

Im a newbie and i live in the uk and what can i use to make a big flame thower, and where would i buy the materials and not one off thoses aerosol can flamers where u but a lighter in front. PLEASE help im bored!      
FLUFFY!


— Posted by Darkie on 1:37 pm on Feb. 21, 2002

DUDE!, look up a few posts tard. I left what i think to be a decent flamethrower text.


— Posted by fluffy on 2:14 pm on Feb. 21, 2002

where ? sorry im anewbie and a retarded

milenko, “dumb enough to pressurize fuel”
how do you think a real flamethrower works?
ever seen one? I have. that’s how they work.

flame sucked into fuel tanks? the “check valve”
remember? a one-way valve. no backfire. that simple.
hoses on fire? not likely. they are behind the flame,
not in front of it.

stop, drop and roll. haha. I’d like to see a TEST STAND do that.


— Posted by Darkie on 6:29 pm on Feb. 21, 2002

Hoses on fire, yea prolly not, but just in case your fuel ate thru and caused a small leak blah blah blah. He he, i can’t get over the nightmereish idea if all of the sudden a strong wind hit u right as u pulled the trigger faceing in that direction.

“Stop, drop, and….DIE, ur covered in napalm, u ain’t goin out till ur crispy!!”


— Posted by bigboom on 12:14 am on Feb. 22, 2002

why wouldn’t a single tank work with a small propane tank at the top

yeah jmb, i wasnt saying that anything like that would blow up, of course the real ones pressurise it, but they’re made outta proper materials that are meant for that sort of thing.


— Posted by jmb1125 on 6:54 pm on Feb. 22, 2002

I do like that idea some what but you can inprove apon taht greatly…
but i dident realise taht the can cant blow up!…. thanks so much i always worried when the flae got to close or such…


— Posted by jmb1125 on 11:17 pm on Feb. 22, 2002

your device system must have an idler flame

jmb1125 would it be possible if you could draw a blue print for this? I cant really picture it,,, sorry


— Posted by jmb1125 on 12:15 am on Feb. 23, 2002

Optical, message me your e- mail address.
i’m not about to try to draw it here.


— Posted by bigboom on 12:25 am on Feb. 23, 2002

thats just a rough draft but ya’ll get the point and i’ll start working on the prototype


— Posted by jmb1125 on 1:38 pm on Feb. 23, 2002

keep in mind this won’t be cheap to build.
$50 to $100 my guess.


— Posted by bigboom on 8:03 pm on Feb. 23, 2002

the main thing that i’ll have to buy is the valves and maybe  parts for the trigger


— Posted by jmb1125 on 11:11 pm on Feb. 25, 2002

bigger cities have “Industrial Liquidators” type places.
these stores kick ass for components and supplies.
many are “close-outs” at cheap prices. lotsa military
surplus type “junk” (not!). 🙂


— Posted by moorey on 12:49 am on Feb. 26, 2002

i’d have thought if u had the air before the fuel.  ie the air/gas cylinder (CO2 fire extinguisher?… or medical O2 cylinder would aid it in igniting- not that is nees it) feeds through a sealed tube and valve into the fuel cylinder, pressurising the whole fuel mixture there.
alternatively, two separate cylinders to a third… similar to the works of a carburator of an engine, i know the napalm etc doesnt need to be mixed weith air, just its another way to think of it.  it may be possible to use parts from some engine, or if ur looking for refilling ur pressure cylinder, ask someone in the know ie scuba tank refillers, fire extinguisher… these things r made already and u could probly steal/aquire/but (small ones) for not too much?  just some thoughts


— Posted by Hergor on 9:32 am on Feb. 26, 2002

forget that O2 asap! (unless you want to put it right to the front end of the ‘barrel’)

if the fire somehow manages to get behind the safety valve this might lead the flames into the fuel canister, even if there’s some way to go from the O2 injection valve to the fuel tank!

but those engine parts are a good idea. those at least can stand the fuel (some other pipes are sealed with rubber rings -> some fuels eat through or get around rubber and then you have a nice mess when the fuel catches fire…) 🙁

parts like that can be easily obtained at ship(junk)yards or normal junkyards…


— Posted by Zambosan on 12:08 pm on Feb. 26, 2002

Yeah, a checkvalve isn’t going to do much of anything to prevent an explosion if the mixture is oxygen-rich… the combustion will travel right past it while it is open… and even if it closed due to the pressure, the intense heat would just ignite the mixture on the other side.  Generally speaking, the whole idea is pretty damn dangerous, since you can get oxygen into the fuel just from filling the tank… just like a carburetor.


— Posted by ilovekayla on 8:04 pm on Feb. 27, 2002

well thats cheap if you can get a nice flame thrower 🙂


— Posted by Shake Your Ass on 7:09 pm on Mar. 23, 2002

Ive tried the SprayCan kind of flamen style and its
just to simple, the aerosol thing and all , the flame is to damn short. So I think the Supersoaker stile is the easiest style of flamen…        Its cheap and its strong and all.

Thats all I wanna tell ya !!     Flame on !!!!!!!


— Posted by bigboom on 1:32 am on Mar. 24, 2002

i’ve done some  prototypes steel far from prefrection but i fill that their all safe cept for the very first one couse of shity welds connecting falvs and hose but they work nicely still working on idler flame


— Posted by Zero the Inestimable on 10:44 am on Mar. 25, 2002

Cans of starter fluid make nice large flames, as far as aerosol cans go.

My design for a flamethrower was quite similar to Darkie’s, with a metal tank attached to a propane bottle. If you fill the fuel tank to the very top and leave no air in it there is no way for it to explode. The propane will fill the empty space inside the tank, and with no oxygen there’s nothing to catch fire. My only concern is the pressure the propane tank puts out – I think you would have to limit your tank size, otherwise you wouldn’t have enough force behind the fuel to fire very far.

Regardless, I would incorporate a second propane bottle and a soldering torch near the nozzle of the weapon to light the fuel instead of a grill sparker. That’s pretty much sure fire ignition, provided you space it right. A metal ball valve would be sufficient for the trigger of the gun, preferably one with a lengthened handle to give you more leverage to open and close it. The propane bottles could use standard gas grill fittings, which should be available at any hardware store.

I’ve always wanted to build one of these things. I may do so, once I finish the rest of my projects…

— Posted by chroniccrescent on 12:20 pm on Mar. 25, 2002

you must always b sure that the gas tank has not got oxygen, or it will explode, this can be done by “flushing” the tank with the propelent (like metahne) but this may b hard to do as there is always a chance of oxygen in the tanks


— Posted by Zero the Inestimable on 3:12 pm on Mar. 25, 2002

With something like this there is a tolerable amount of oxygen that you could have in the tank. If you have three gallons of fuel and only a few cubic centimeters of air, so what if it ignites? That isn’t enough oxygen to ignite enough fuel to do any damage to a metal tank that you’re already running 500 PSI of propane through.

~Zero the Inestimable


— Posted by johnny 99 on 3:28 pm on Mar. 25, 2002

I think you better go outside and look at your propane cannister. They run more like 30 psi. which isn’t nearly enough to project a thickened stream fuel very far.


— Posted by Creeper on 3:48 pm on Mar. 25, 2002

Ha!  here’s a novel one!
Why not…..Hold a match in frount of a de-odourant can!?!  I heard about the possibleity of the can blowing up but…..If your stupid enough to try and make a flamethrower in your garage then I suppose you deserve it!


— Posted by Zero the Inestimable on 9:36 pm on Mar. 25, 2002

Do they? I have to check on that. I’ve seen those things blow before, and they seemed to pack a lot more than a measley 30 PSI.

~Zero the Inestimable


— Posted by Zero the Inestimable on 9:42 pm on Mar. 25, 2002

Quick research indicates that a full propane tank runs at about 250 PSI. That’s a little more like it, I think.

~Zero the Inestimable


— Posted by johnny 99 on 10:49 pm on Mar. 25, 2002

My apologies Zero, I stand corrected! Don’t know WTF i was thinking about. your right I just checked the one on my BBQ is rated to 240 psi. sorry.


— Posted by GhEtTo BoY on 12:54 am on Mar. 26, 2002

i got an idea
check out my post on flamethrowers ^_^


— Posted by golkar on 7:39 pm on Mar. 26, 2002

I seem to remember that military flamethrowers carry the fuel in collapsible bladders within the tanks. A pressurizing tank would press on the bladders, forcing the fuel out.  I also seem to remember that the early models killed about as many operators as they did enemy.  Perhaps nothing is as it seems.


— Posted by yourunforgivenII on 11:50 pm on Mar. 26, 2002

i dont know much of anythingbut what if you made a big pocket sized one using really high pressurized gasoline (if theres some stupid thing about that bare with e im a 12 year old) then shoot it and pull a separate igniter, maybe some kind of electrical or flint sparker, like on a liter, and shoot the gas through it, would that work ?


— Posted by bigboom on 7:16 pm on Mar. 27, 2002

i get about 12 feet with my flamethrower and its just got a small propain tank the kind about 8 inches tall the fuel tank is about 12 inches tall and about as wide as a softball i’m prolly gonna set it up with 2 propain tanks though


— Posted by XxBULAxX on 10:09 pm on Mar. 27, 2002

Melinko, what you said abouve about pressurizing fuel…even if the flame touched the nozzle, the flame won’t go up the tube if theres no oxygen in the fuel line..


— Posted by bigboom on 4:15 pm on Mar. 29, 2002

hey XxBULAxX TGM is gone, i’m now working on another tank with dry ice to help push out extra oxygen also by turning the tank up side down and runing the propane through it pumps out the oxygen whith no fuel just small amout lose of of propane  


— Posted by Stiggs on 9:19 am on April 2, 2002

hey, here is something for a bit of fun, it is not a fully constructed flame thrower but hey it looks cool.
get a deoderent can from home and grab a lighter then hold the can up right and light the lighter uderneith the spraying particals about 3-4 cm’s away from the can then when the flame hits the spraying particals depending on how far the spray squirts out of the can thats how far your flame thrower will be


— Posted by super steele on 1:30 pm on April 2, 2002

For a pocket flamer thrower if any body was stuck with an ignition device…i have the perfect one. Take a disposible camera and remove the flash circuit from it…then run two wires from the capacitor (when doin this wear gloves…these babies are 330v even though they only run of 1 AA batery)and short these wires toghether..this wil be your spark. Now where the button to activate was…remove the metal pop up contact and replace it with two wires running to a push to make. To make a spark suitable for igniton (and maybee defence) simply hold down the push to make and the saprk will ignite anything sprayed onto it…The whole circuit assembelly is only about 20 square cm. And the disposible cameras can be aqquired for free!!! just ask at your local devloper


— Posted by Minion2000 on 8:38 pm on April 3, 2002

making a flame thrower isnt that hard to make really it is sorta easy all you need is a
1.any flamable thing that is in a can
2.A lighter
Then just hold the lighter up to the can then boom a flame thrower


— Posted by bigboom on 12:39 am on April 4, 2002

man minion and stiggs are dumb, im working on a pocket thrower useing 2&1/2 pencil torches 1&1/2 are welded or sodered together this holds the liqued fuel the other holds the pressureizing propen witch mounts into the other part witch will go to a tube then to ignitor and thanks to super steele i now have a easier ignition device


— Posted by rgm576 on 6:29 pm on April 9, 2002

ok noone has a welder so i suggest the old super soaker coat hanger gas and rag  works fine a windex bottle can replace the super soaker


— Posted by rgm576 on 6:32 pm on April 9, 2002

spraycans and lighters are for children but if you want to blow your hand off……………


— Posted by InSoMnIaC 99 on 7:20 pm on April 9, 2002

Well I have an idea boys…mostly educated guess and creativity…you could have someone that is good at welding make you a metal tank…or maybe even take one of those tanks you fill with air…you know the 5LB portable air tanks for airing up your car tires…well maybe take one of those…then rig a system up that would do this…you have your fuel…propane/gasoline/o2/whatever…it would work best with a liquid I would think…or hey hey…a good napalm formula is this…like a gel/liquid stuff almost…gasoline mixed with alot of egg whites…they gel the gas…and some salt…I hear people use it in molotovs and stuff…maybe use that as your fuel…then have the tank full of your napalm or just straight up gasoline in the tank…you have a 30 ounce co2 canister at the top of the tank as a propellant…that would push the napalm out of the tank through the hose down your barrel…and the barrel could be made of metal tubing…copper or aluminum or something…and also…you would have to put a valve on the end of your barrel…and one for co2 so that way you open the co2 valve then you open the barrel valve and it lets the mixture rip…that would probably shoot the shit 20 feet or more…wouldn’t last forever…but thats where bigger tanks of fuel and propellant come in…you could use a aim ‘n’ flame or gas grill igniter to light the fuel…I think that would make a kick ass flamethrower…what do you guys think…that’s just the crude idea…gimme some feedback on this guys. 🙂


— Posted by bigboom on 7:27 pm on April 9, 2002

first off theres a edit button for the purpose of double posting newbie bitch 2nd your 2 ideas are also stupid its gotta be leak pruf gas will eat away at the rubber seals and plasic


— Posted by KrazyKilo on 11:44 pm on April 9, 2002

Fuk all that shit. for real easy fun, take a super soker and strap a candle on the end of it. fill it up with kerosene, light the candle, and let er go. it shoots pretty fuken far too


— Posted by chico14 on 10:31 pm on April 10, 2002

get an air spray can(lisol,clorox,…etc) and some small candeles(stick candeles) and make it like this.
                                  * = candels _or|=can ~=fire  #=nozzle  aka where spray comes out.

Get hold of Mr Bensons book “breath of death” . My mate made one similar to the one in that book and it fired a flame about 25 meters when it was working good then the bastard proceeded to torch my paddock basher with it.If I were you I would look up one of the swedish infomania sites Ive got a funny feeling you may find the book in question there.
