DIY Flamethrower - I need to build me one! (56k warning, but so worth it!)

i want to try it but since i don't know what the plumbing is made of i'm afraid of the alcohol eating throught the plastic and showering me in a highly flamible liquid. although i'd seen it done with BMW window washer,that didn't do anything to the supersoakers.

/me has a sudden urge to play Blood (1)

 

its pvc and brass so its fairley safe. he also hase a safty valve to stop the alcahol running back into the tank.


PVC is fairley alcohol resistant. altho when he charges upto higher pressuer all the alchohol isnt vaporised so there is alot of unburnt stuff in teh flame.

can soem one sign up to that forum and tell/ suggest he adds a atomiser of some form on the end of the gun thing.


he coudl also get a higher range by useing a fire extinguisher (modded as the fuel tank. there rated at abotu 500psi (afik) so modded would bring it down to about 300psi.

 

Irony!

I'd like to know exactly how he ignites the fuel jet. 'Real' flamethrowers use a small additional gas canister and a Bunsen burner-type arrangement so that there is always a pilot-light just outside of thr nozzle. IIRC they also use nitrogen as a proellant, since it has the wonderful property of NOT helping alcohol to explode...

 

they actually use the butane to presurise the tanks aswell as the piolet light

in his version the piolt light is a blowtourch strapped to his belt with a remote nozzle stuck to the flamethrower.

Wow, and to think that when I was a kid I used LEGOs and sticks for play guns! This kid either has too much time on his hands, or some serious pyromania. Most teens don't have the ambition for something like that, so I give him props for taking the initiative. In high school my brothers and friends would make potato guns from PVC and pushbutton BBQ grill lighters. We never got caught or had to explain to the police what they were, and I was always a little worried about it being classified as a firearm. Makes me wonder what kind of stuff my kids will come up with...

This guy might be the flamethrower kid's dad!

All I can say is wow.

Reminds me of this guy who attached a flame thrower system to his car so that if you tried to open the door when it was locked, you got pretty toasty.

 

IIC thats an option in cars in south africa due to the amount of carjackings in south africa there is now a flamethrower option on the cars that puts a 6' wall of flame on each side of the car at teh push of a button. i think there was a artical in the inquirer about it a while ago.


EDIT: i knwo a guy who moved from zimbabwe(SP?) to here and couldent import his clio over here cos it was flamethrower equiped. and was quarenteened at the dock.


EDIT 2: if i remember rightly aswell. there were safty concerns but a chief medical officer said if iremember the quote "there is very little chance of death. but it might possibly blind the victim as they woudlent stand there and get roasted alive" or something along those lines

 

The man is correct...has been around for a few years now.

'doc

 

I remember seeing it on TomorrowsWorld years back, was a just prototype on a BMW then!

 

Dont forget the suitcase mounted one either the same man made for his house.

 

I wasn't aware that it was an actual option when buying a car but I'm guessing it would be a definite deterrent to any would-be thieves.

However the point that you wouldn't be able to take the car abroad would bother me (if I could drive).

 

I am going to have to buy my own cruise missile from this guy...or at least try. Has anyone contacted him? I want one, just to put it in my backyard or something. can you say "theft deterrent"!

 

Or you could invade a neighbouring house (declare war!) with it!

PS in your sig cogito, it should be cogito ergo modo because in latin the first person ("I") has to have an "o" on the end, although an exception is "sum", which means I am.
