So anyway i was bored so i decided to make a flamethrower out of the 45kg LPG cylender that i found... yes... foundd..

http://img142.exs.cx/img142/7887/pc290002medium9oz.jpg


Attached some tubing to it to redirect the high pressure gas to a safer place to burn off

http://img142.exs.cx/img142/8195/pc290003medium0ko.jpg

Then ran the tubing to this baby, 2 meter brass pipe, nothing is gona break this baby (complete with saw horse support stand)

http://img142.exs.cx/img142/4347/pc290004medium2nm.jpg


So annnyway i run this whole rig outside and light the pilot light (cloth soaked in metho wrapped around the pole)

hehe

total fire ban?

also, thankyou for doing your bit in preperation for the terrorist invasion

you are so negative, maxe

haha maxe

thread title has "so i..." in it, banned ;)

That's pretty cool, maybe not as impressive as I might have hoped, but good effort none the less. Maybe try to somehow make it higher pressure or something to get a flame that goes further?

the pics dont do it justice unfortunatly, the video is a little better... the flames are way over my roof at the moment anyway and i really dont want to go higher for fear of people thinking that my house was on fire (more)

Thanks for knowingly making the thread dialup unfriendly rather than taking the time to simply host with imageshack and using the thumbnail option.
As if dialup users weren't alienated enough already
You're a true credit to the internet.

cool

i cant see any possible problems occuring mucking around with gas and flames

keep up the good work josh!

hehe cooldude.
Id do something like that... actually no I wouldnt - lazy.

total fire ban?

"there are currently no bans in place in queensland"


Fire ban info line :)
1800 020 440

Also for the broadband haters, im not thumbnailing s*** because it detracts from the magnitude of my efforts kthnxbi

Broadband haters?

Splat, normally I wouldn't care about having issues loading this thread because having your nick next to it is synonymous with a flashing sign that reads "Who f***ing cares?"...

but after the amount of bulls*** broadband-woven arrogance towards dialup users that's been ocurring on the internet lately this was the straw that broke the camels back.

One can only hope that cannister springs a leak.

I can only assume that this will become a beacon to stupidity everywhere and if we're all lucky will end up in a Darwin award that we can say we all but saw unfolding before us.

P.S. That's awesome!!!!

hashy even tho you piss me off i still love you. dont ever change

Hey splat, get a flashback protector on the end of the bottle, it stops the flame sucking back into the bottle and exploding. Pretty cool though, just be careful without flashback protector.

use it to light yourself on fire!

looks pretty safe and useful

use acetylene + oxygen for bigger flames, and bang if you get it wrong

You idiot Josh.
Well done :)

oxy and acetylene is mass fun, go buy a 2nd hand oxy kit and modify the torch

Hey, a 45kg tank attached to a 2m brass pipe giving him a great balance between accuracy and the ability to burn his own eyebrows off will make him more prepared for when the terrorists attack than most of us.

I have to say that the video was quite impressive. In fact it was one of the most impressive things I've seen today.

i like how the pics depict him hiding next to the gas bottle

burning stuff in such a manner... quite unlike you splat...

Is that sprinkler hoseing attached to the gas canister?? hehe i cant wait to see the news tomorrow :p

supersoaker flamethrower is so much better.

Hurry up and post a movie of you blowing yourself to bits

so your selling what now?

Cry more hashy!

I love it when people do something increadably stupid. and i love it even more when it backfires.

all in all, thanks for entertaining me. :)

die more Hellman109

Hey where is the *children don't try this at home* warning?? I might do this now and hurt myself and SUE YOUR ASS!@!!@#!@ :p

Hellman109?

As in the guy who wacked it at QGL?

Oh my

Thanks for the info about the blowback protector, i will get one before i do my next experiment...


speaking of which...

Im going to set it up horozontal and put a old computer in front of it then fry the bastad in the middle of the flame

then next weekend im going to set up a bubble matrix on the bottom of my pool and ignite it after the gas bubbles to the surface hence "lighting my pool on fire" .. will be a good effect i guess

but blowback protector is my no1 priority at the moment, these things must be safe !!!

Is that sprinkler hoseing attached to the gas canister?? hehe i cant wait to see the news tomorrow :p

Yes :$ but gas is reverse thread so i had to typa shove it in there. Safety was a main concern so i shoved it in good

This all sounds like one big parody thread or something awful ripoff to me.

surely splat isn't this silly/immature?

i'm voting gimmick

I guess there's a lot to be said about gimmicks.

surely splat isn't this silly/immature?

im not the one getting my weiner chopped off

hehe jokes :)

I DONT HAVE A f***ING CHOICE IN THE MATTER

NOW WILL YOU f***ING ASSHATS STOP BRINGING IT UP AND f***ING TELLING ME IM THE ONE WHO WONT SHUT UP ABOUT IT

f***

Fire up!!!! (I'm not even sure if I'm talking about "Melissa" or the flamethrower, LOL!!!)

THERE IS NO AMOUNT OF CAPS LOCK ABUSE THAT CAN EXPRESS HOW I AM FEELING

some guy on SA made one of these a while ago, but his was strapped to his back.

There is no originality on the internet.

SA is the origin of all web content.

Can anyone lend me :10bux:?

This thread is already retarded enough thanks, it doesn't need your help.

haha hashy exactly what I was thinking everything is done on SA first...


also laff - this is deffinately a josh/splat/lowgoz thing to do it's actually pretty good :)

cmon kids, stupidity on a grand scale was the original point here - let's get back to what made this thread great.

hey I wasn't saying omg old, the point was the guy on sa had his strapped to his back. I can't search since I don't have that ability so can't find the pics.

That is one of the most silly and imature things to have done Josh...and I like it!

8-)

At least this thread doesn't need more dragons as much as most do.

Ok, i talk about safety and you know, im really crash hot on safety

and IM NOT STRAPPING ANYTHING TO MY BACK. Maybe a smaller bottle but no f***ing way 45kg of LPG no f***ing way in hells god green earth

I see a lot of people have stairs in their houses. Yes i saw the SA thread but he compressed petrol in a backpack which is completly unsafe compared to my garden hose design

http://www.powerup.com.au/~boldajis/images/cylinder_doom_final.jpg

a handheld design wouldn't work with lpg because you would need a big tank capapable of dumping a high volume in low amount of time which means you manafacture it yourself. its way to risky with the chance of explosion of the tank and whatnot, low pressure high volume is better

anyway.. the pool mod of this is coming to qgl in 2 weeks

Hahaha

rofl @ photoshop

Nice work Josh :)

Dont encourage him.

awesome work goz

would make a neato nye party trick

i reckon if you added a venturi at some point along the copper pipe you would get heaps better flamage, probably blue flames rather than just pussy yellow/orange flames. towards the end of the copper pipe would be a good place for it i guess. a venturi won't work under water, unless it is placed before the pipe goes under the weater. failing that bung on a compressed oxygen cylinder... but use sparingly or it could go bang. instead of compressed oxygen you could also just use compressed air from a standard compressor, i wouldn't pump it through at a full 8 bar though.

flash back protector or whatever it was called sounds like a good idea to me if you are going to start using air or oxygen at pressure... if you don't, the flashback protector seems a bit pointless, how the hell will the gas ignite right back at the gas cylinder when you have several metres of hose ?? The isn't any oxygen in the pipe... unless you have an air leak in which case air may being sucked into the pipe, or gas pumped out... test your connections with soapy water in a spray bottle, and seriously consider buying proper brass fittings to plumb the gas from the cylinder. you don't need copper pipe the whole way, you could just use proper flexible gas hose.

Yer they are called Flashback Arrestor's, But you they can still fail,

I remember at tafe We got the talk on safety with Oxy Torches, Was rather scary when your working on your project and bang, backfires scared the s*** out of you at the time,

Was told that if a flashback went to the cylinders (this at ithaca tafe) It would blow up the entire block, Pressurized cylinders are VERY dangerous s***, Even small cylinders have potential for Massive explosions.

On That note, Flame on ! :)

Most large gas cylinders used for welding (oxygen, acetylene, argon etc) are filled to about 600 BAR, that is 600 times normal atmospheric pressure... so a 10 litre cylinder for example filled at 600 bar is holding 6000 litres of gas (if it were not under pressure). Massive amounts of gas, under enormous pressure, when they go bang it is catastrophic... I am sure many people have heard this, but if one of those gas cylinders fall over and the brass regulator and tap assembly is knocked off they take off like a missile, after all there is 600 bar pushing it along. A bloke at my work saw one get dropped out of a ute when it was being unloaded, it went up into the air, through a 2nd level window of a building and out the other side of said building... they are also known to simply punch a round hole straight through brick/concrete walls if the top is knocked off. That is why they should always be secured with chains :o) At work we have several cylinders and only 1 was secured, then I chained the other one... we still have 3 unsecured... pretty dodgy. People get complaisant I suppose.

For a bit of fun, next time you light your oxy-acetylene gun, have the oxy running when you light it (normally you just run the acetylene), it sounds like a .303 when it is lit... it is sure to make the biggest man s*** himself :o)

More stories of gas related incidents pls.

BTW your 45kg LPG cylinder isn't filled to 600bar... something like 150bar i think, i am prolly wrong though.

Anyone got any plans for a pneum atic spud cannon or combustion one :).

Combustion ones are pretty easy, you just get the electric started from a lighter and use aerostart (which is like ether and petrol in a can).

parabol wins the thread

Over in salisbury there in a factory they use to get huge long bits of H iron and sit acetylene bottles in it and knock the heads off em and they would fly through the rail, one day it went through the wall and out onto the main road, in fact I think someone copped it in their car.

its funny you mention spud cannons because this is what started it all.

If anyone is gona make one pls make sure you use PRESSURE RATED PIPE.. at least 120psi ! If you use normal downpipe or normal PVC it will explode on you and you will get shrapnel! Make sure you are safe people!

All the lpg cylenders have collars on them to protect the top valve but if that baby does come off hell will ensue.

Didnt Hitler and friends expierment with flamethrowers as weapons in ww2? With lots n lots of failurs?

yeah, but im like.. smarter

hehe

RIP Lowgoz...

asif youd light your oxy without a little bit of oxygen... pure acetylene = paratroopars ohnoes

You're not meant to use oxy when lighting the acetylene.

but breathing in all those chunks cant be too healthy either

meh, do it quickly, the chunks only come off when you back the acetylene off to turn on the oxy mixture.

I know your not meant to use the oxy when lighting acetylene... hence it sounds like a rifle going off when lit.

As for spud guns... i was going to make a combustion canon for shooting golf balls... reason i was going to use golf balls is because they fly well and are uniform size ensuring consistency when firing and enabling good compression as you can make it a firm fit in the barrel etc. I have access to good materials at work and lathes/mills etc so i could make a very sturdy explosion chamber and the precision of the barrel would be no problem. I was even toying with the idea of using a rubber sleeve at the start of the barrel and boring it to be a fly s*** smaller than the diameter of the golf ball.

I was thinking aluminium for the chamber and where the ball sits and using plastic (PVC or other) for the barrel... the barrel itself shouldn't be under too much load...


Anywho i haven't got around to making it yet though... would be pretty lethal I imagine if the golf ball were to strike someone. Also golf balls aren't cheap, cheapest I saw when researching it was ~50c a ball when bought in bulk... pretty expensive per shot imo

Go pay like $8 for a big bucket of them at a driving range... and do a runner ;)

...or take the cannon to the driving range and see who wins eheh

http://www.spudtech.com/content.asp?id=14

mught be helpfull to u mate

Someone start a funeral preparation thread. It's better to plan early and book ahead to get us a discount.

Last spud cannon i had a go off was all PVC. :P

Was like a 2.5 inch barrel, with a 4 - 5 inch combustion chamber. It was all done with standard PVC drain parts, igniter was the static thing from a lighter.

Funniest thing was a guy attempting to load a mango into it after a missfire. He stood the thing vertically, pushed the mango in and put the base of it on the ground. That clicked the igniter, and out shot the mango straight into his face.

It mightn't have been so funny if i didn't think the guy was a complete cockwallet.

although it's pretty cool.. does anyone else think it's incredibly stupid to use a 45kg bottle of gas that you FOUND ??

you probably found it for a reason, cos it was farked..

could have come off the back of a ute or truck.. (not secured properly) still dodgy..

Rodolphe where do you work??

I work for my dad and we do workshop fabrication work, fabricating pressure piping and s*** like that for fuel refineries like caltex/bp..

We have oxy and acetylene bottles up to our ears :) and about 10 bottles of LPG (130kg) bottles oh and one very old bottle of Helium (dunno why)...

Oh and acetylene will only stay a light if it has the perfect ratio of air to acetylene. So in theory acetylene when lit won't travel up up your hose as there is no presence of air (in the same tube).

Flashback arrestors are just a way of making money for the guys who invented them and for the supplier and to comply with legislation.... Thats all.

Helium... sweet.

Helium is used for laser cutters I believe, we have huge laser cutters at work and I'm pretty sure they use argon,oxy and helium. Also flashback arresters do work, one of the tradies at work had a flame suck in through the pipe, blew the pipe off and had a little flame coming out the bottle ( he was a moron and just ran out the factory and didn't tell anyone), when he came back the flame had subsided but he was lucky. I wouldn't ever use an oxy without one. Also another story, out in the darling downs area they use to use acetylene bottles (small ones) which would open and close the valve at set times during the night and s*** to scare away crows.

Hello energex how can I help you?

Hi, would you like to know what gas bottles are being used for? I will send over some pictures and a movie. Yep, works at the uni, yeah, name's josh, thats the one.....cya!

Might I also add that just have oxy and acetylene unlit at high pressures will explode.

There was a worker killed over in Charlotte, NC(USA) a couple of years ago that didn't have them on his cutting rig. He ran out of oxygen and went to get another bottle without shutting everything down correctly so that acetylene flowed back through the lines and accumulated in the O2 regulator. When he changed his bottle and cut the O2 on, the resulting explosion buried the t-handle from the regulator in his chest...killing him

Remind me never to touch any of this s***.

i have enuff dramas just attaching the gas bottle to the bbq

stupid reverse threads

Oh yeah just another tidbit, if the check valves on the torch stuff up, or you dont have them, thats when the s*** hits the fan, and I can guarentee 100% if you didn't have an arrester it would flashback and blow the cannister

lthoughdoes anyone else think it's incredibly stupid to use a 45kg bottle of gas that you FOUND ??

you probably found it for a reason, cos it was farked..

Next door is getting demolished to make way for a subdevision - they cut the bottles off the side of the house and threw them in the junkheap

Being the alert citizen, i removed the gas bottle before it was picked up and punchered by the excavator. Last time i checked the council didn't like people dumping full 50kg lpg tanks at the tip.

Think of it as a service im doing to the community (apart from blowing myelf up)

Last time i checked the council didn't like people dumping full 50kg lpg tanks at the tip.

stop being a hater astroboy, it doesn't suit you

lol.. okayokay

my dad works for kleenheat gas actually so he knows ALL

you finished chemo anyway grunt?

i am a fitter/machinist at a small machinery manufacturing workshop... nothing exciting. i do all the cnc machining and some lathe work.

only good thing is access to good materials (platics, ally and steel) to make foreigners :D

can you make me an asian?

lol cnc's, the most boring of all jobs is doing work on CNC's, I guess its ok to do setups and code but otherwise it's ghey. I only did it because I had to do it as part of my aprenticeship but I plan to never touch them again.

I'm also pretty lucky in regards to steel, also rodolphe whats the name of the company, and do you or have you heard of Cox Industries?

do you work for cox spoon?

teehee

yer cnc is gay, but i am programmer AND operator so it is ok, and we only ever 20 off for a part so i'm not hitting cycle start for the same part 1000 times :o)

The name of the company is Modra Automation it is at meadowbrook... i think I have heard of cox mowers... related company ?? The people who do our gold pasivating (uniline) do the stuff for cox mowers I think and a guy I work with used to work at cox mowers...

Lol which guy, I work in the R&D department, so we got the best equipment and best looked after. When I was doing the CNC's is was when we were selling them and outsourcing so we were doing 600-1000 parts each go to get stock up, deburring was fun..or not. But yeah Cox Industries was Cox Mowers, we just changed the name.

name of guy plz

His name is Jason, a Canadian guy...

grey hair and s***? I only knew of one candian dude and he was the fabricater there

negative, ~30 yrs old with long black hair, afaik he was on lathe work... meh, teh world isn't so small after all :P

But yeah Cox Industries was Cox Mowers, we just changed the name

your mowers throw belts and the springs break

which model? Because I know the conquests do. Personally I don't like the new machines, the old ones were the best.

Which machine and which springs?

new red one with headlights. Ill go to the shed later on and find out exactly. i think the clutch cone has a f***ing chip out of it too :/

Yeah mang thats the New Gen, they are actually a pretty good machine. The clutch cone is probably f***ed, I suggest you get a new one with this material we are using, its magic gear.

I use to work in service and I have never seen a broken spring, nor has the belt come off, the belt rolls when it goes up to far though and I assume the deck needs adjusting. I might also add the belt will come off if the springs aren't on there because they are what tensions the belt, unless you are speaking drive belts which I just can't see happening unless you got like a heaps old school one. Take it back to the dealer.

If you are having probs with it and the dealer isn't giving you satisfaction you can ring warranty/service dept and they can collect the mower or you bring it in and fix it for you and usually do a whole service eg new cone, new oil, air filters, oil all components. It's not rare that you get a lemon because they push like 40 of them things off the line a day, even upwards of 50 some days.

Edit: also the line isn't automated it's all built by hand so yeah someone might have been slack and missed something to do with the belts. gimme some more info and I can tell you what to do with it.

So when is the next thing being exploded/set fire to?

when i get back from syd next sunday and get a flashback arrestor and some kevlar

hey spoony

nah mate she just threw her main drive belt, i slid it back on and its fine now.

Spring broke that holds the blade engagement lever in the upright position so the blades will come down easily because there is no backward resistance on the lever to prevent it.

Its around 2 years old tho and yea its new gen cox. Ive had no probs with it, great little thing. I need to replace the blades tho and get a service for the tensioners and springs and crap like that. How much would that cost with you guys?

Out local cox dealer is a f***ing dodgey bastad.. wrote off our old mower as a "fire" so we could claim it on insurance and get a new mower off him.. hes been ripping us off ever since with parts for the cox so we just have started going direct (to you guys i guess) to get replacement parts.

Oh yeah, kind of weird thing to happen, but yeah the spring is under a fair bit of tension for the engagement lever, I would say possibly that the spring was a bit dodgey a flaw in the material or something. I think unless you are having serious issues with the machine you will have to take it to a dealer, but ring and find out anyway. And if you can tell me the name of the dealer because I know most of em and have met most of em. Also is the whole machine red, or is it black and red, eg black chassis and red trim?

Edit: I can prolly hook you up with a good dealer who will do the right thing by you, my old man is the GM at cox mowers so maybe I can work something out

hot s*** buddy

Completly red with headlights (j0r)
ill drop you an email next weekend and ill grab the details off you. I put the poor thing through .5m grass today (only 1m long) and it got mad at me, then i drove it up 45deg incline and the blades hit the ground

You dont wanna hear that do you

i took good care of it :D


Also, pic of next project

http://img96.exs.cx/img96/9048/image30tx.jpg

that hose isn't gona be near the flames btw, its psp's fault of that.

The red thing is an armor shield made out of cardboard


.. no seriously

lol, the height of the grass is fine, but yeah usually 15degree inclines are max, that is if you were contantly mowing at that incline, otherwise I reckon it would be fine. I can probably find the part number for the blades and grab some for free for ya.

anyway email me at jokah@optusnet.com.au

corrugated cardboard???

on the subject of bubbling gas through water and igniting it... i tried this trick once many years ago on aust day while very drunk... i got a can of butane (the ones you use to fill lighters) and stuck it under the water of a kiddie shell pool, i pushed back the valve and stuck a lighter above the water to light it... i ended up singeing my eye brow, hair on my head, chest hair and one of my arm pits... thank f*** i was pissed, therefore it was funny, not stupid.

they push like 40 of them things off the line a day, even upwards of 50 some days.

Production lines kick ass, I got a tour of the Hitachi one in Japan where they push out 180 excavators a day.

Yeah, we only got like prolly 12 dudes on that line aswell, so it's a top effort. We do everything in haus too except for machining parts since we sold the CNC's, but we do all the fabrication from getting the steel off a truck all the way to being painted, which we also do there.

It's a great place for foreigners tho, we got f***ing huge laser machines and turrent punches and automated benders. Some dude at work got a FPV logo cut out with was like 1.5mx1m and got it all painted n shiz.

I'd like to see some of the more advanced assembly lines tho but I think we maybe getting some automated things put in, like conveyers which bring completed parts into each workstation etc. Alot of it is becoming automated now we have 2 big robot welders there.

Edit: I would never become an assembler :) It's the gayest of all jobs.

Pity it's not really going to do anything to help you if the god damn bottle wants to go kaboom, and that's what I'd be worried about, particularly since it's on the same side of the "shield" as you. lol

i think the shield is to protect the fire from more stupidity

haha

nice one partyhat

have a good one tonite!

hrm im a bit of a pyro but i dont think id be f***ing around with a 45 kg can-o-gas thats just asking for something really REALLY bad to happen :)

cheers dude, u too!

hrm im a bit of a pyro but i dont think id be f***ing around with a 45 kg can-o-gas thats just asking for something really REALLY bad to happen :)

im in the same boat as you i dont think i would be stupud enough to make somthing like that although i did make a potato cannon which was pretty dangerous
