A gun/hose assembly, and the tank:

It’s made entirely of parts you can get at your average hardware store. The hose connects to a stop valve, which connects to a short pipe nipple that's tapped directly into the tank.

The tank took a while to make, because I let each set of chemical welds dry before doing the next ones. The ends of the tank are two 90 deg. elbows and two 90 deg. street elbows, welded to make two full 180 deg. "U"s. One side of the tank is a 2' length of 4" sch.40 PVC, the other is a 4"x4"x1.5" T with standard pipe attached to each 4” socket.

Before assembling the parts, I drilled and threaded the two holes I needed in the tank ends: a 1/4" standard pipe hole for the outlet to the hose, and a 1/8" standard pipe hole for the valve that I would use to pressurize the tank. Interesting note: 1/4" and 1/8" pipes have no actual relation to the measurements of distance commonly known as the quarter inch and eighth inch. The holes are actually 7/16" and 11/32" respectively. Hooray for non-metric measurements.

Next step: cement one end of the tank:

Then the other:

After the tank dried, I dredged up an old camping backpack to hold it. I cut a hole in the bottom of the pack and screwed the gun/hose assembly into the base of the tank.

Finally, I screwed in the Schrader valve (which I bought from www.spudtech.com, an excellent online retailer for PVC weapons and parts) to complete the tank:

Now the whole rig was ready for some pressure testing. Since I would soon be running the distinct risk of giving myself heat-assisted, deep tissue exfoliation, I was extra-careful to make sure there weren't any leaks. I used up a lot of Teflon tape.

And, after filling the tank with water for a trial run, made sure the cleanout cap was on nice and tight

before flipping on the air compressor.

No leaks! At this point, I had quite possibly the world's most kick-ass super-soaker.

Of course, I didn't go through all that effort for a damn squirt gun. So I added a pilot light in the form of a blow torch.

Much better! The finished product:

There was only one thing left. Add some fuel (denatured alcohol; PVC is soluble in gasoline)

And TURN UP THE HEAT.
 
I'm pretty sure everyone in the World has seen this :P

I'm sure it was posted here....
 
Yea, it's true, I retract my statement, something like this is worth another look, and just incase someone missed it.
 
Yeah, the ol' Something Awful flamethrower. Was impressive.
 
yeah, there's also instructions to make homemade bombs on the internet too, you gonna give those out to the kiddies too?

Awful that something like that can be built by anyone :(

With the exception of nuclear weapons, most any weapons can be built by someone determined enough. I don't know about anyone else, but I'd rather applaud and encourage the inventive and constructive people around us, rather than try to limit them.
If he blows up his house with it, thats something alltogether different though. :laugh:

More worried about him blowing up my house ;)
 
i find that an aerosol can and match stick deos the trick for me, but then all i used it for was melting plastic elephants, if you want to know the best one its WD40, its an oil lubricant and used correctly a very very hot bitch.

Yeah I've tried that...The really good ones are where it comes out as a stream/jet rather than a misty spray.

Brian, I would have thought the other end would work better :O
 
Flamethrowers are all well and good, but aren't they against the Geneva Convention? :0

No, the other end becomes a chemical weapon, which has been banned in 49 countries.
 
It occurred to me while I was powerwashing my deck that if you attached a liquid propane source to the powerwasher, and a blowtorch to the end of t nozzle of the sprayer you would have a gas powered flame thrower. Anyone is free to try.
 
Certain types of chemical sprayers can ignite if used too quickly also.
 
Hmmm, it would work better with NAPALM!! :flame:
But for that you gotta make the tank better, as well as the nozzle, but that will suffice :devil:
 
someone already said that in first few posts, next time, read, then post!
 
when you look at it laying on the groud finished int eh backpack it looks like a home made ghostbusters pack thingy
