13579's Flamethrower Help/Guide
Thought I'd just dump all my progress and pictures in here, alone with any tips or tricks to help you construct your own flamethrower. I'd be happy to answer any questions.
Tests ran at 120 PSI:

Pictures:
The gun portion.
The fuel tank. Kerosene is poured in through the center top hole, then the dip tube is inserted. It's pressurized through the quick disconnect fitting, via an air compressor or the second tank.
Gun connected to tank portion
Airtank connected to fuel tank. Tank valve is opened, ballvalve is opened, tank is pressurized via air compressor. Ball valve is closed, hose is a female quick-disconnect that is connected to the main tank to further pressurize it.
The only fuel we've been successful with is Kerosene, and it only worked twice. The day we took the videos, and the 4th of july (2009). Every time I've tried it since, the pilot light (Propane torch) fails to ignite the kerosene.
I plan on rebuilding it soon, however you can get the basics of how it works if you'd like to build your own.
For fuels, Kerosene is pretty much the standard I've set. Safe to use with compressed air pressurizing it (In my experience). I'd like to try diesel when I get it working again, for a cheaper alternative. Denatured alcohol was used by the guy on Something Awful's forums who made his PVC flamethrower, however where I life it's rather expensive (About $20.00 a gallon). Works well, though.
Gasoline is about the most unsafe fuel you can use, in my opinion. Doesn't mean you shouldn't use it, however, just /NEVER/ with compressed air. Nitrogen or co2 would be something I'd work with, however.
There is a website selling some plans to make a nice flamethrower, http://flamethrowerplans.com/
However, since I don't believe in charging money, and since there isn't a torrent I can find of it, I searched around their website, and found their downfall. They have a thumbnail preview of their plans. They didn't count on anyone zooming in on it.
If you try really hard, you can read the words, and easily make out the picture diagrams. Here's the link: http://flamethrowerplans.com/wp-cont.../Picture-6.png
And here's a picture I made after squinting for too long at pixels:
The design is extremely similar to my original plans, but I had a budget of $0.00 and what I could steal from Ace hardware. Basically, the airtank is the fueltank, and the high pressure paintball/co2 tank is used to pressurize the airtank. Our gun portions are pretty much the same.
When I remake mine, I plan on using that design. First thing is to get a job though
With this information, you can make a pretty badass flamethrower. Hope this helped anyone, feel free to comment or ask questions.

I think it's time I revived this project.
You better make something fucking amazing with all of that.
I have no idea what to make...most of the parts I need, I can't really make...pressure tanks and pipe fittings...
Depends on how much stuff around your house you can already use...the most expensive parts would be the pressure tanks and the air blower/propane torch.
I haven't really spent any money on this, most everything was found behind my house, or donated by friends with jobs who wanted to see it work (Pipe fittings).
Alright, I'll do it in a bit here. There isn't anything the picture doesn't really give, just labels the obvious.
Shitty MS-Paint images of what I'm thinking. Two triangles, at the front and back of the gun, connected with rods that span the length of the gun. Both triangles will be CNC-Plasma cut out of thin aluminum (1/8 inch).
Why?
Because it's going to look fucking cool-
Two pilot lights instead of one, and two propane tanks. Hopefully no trouble igniting-
Pilot lights will stay where they are. Had a lot of trouble last time due to it moving since it was only secured with duct tape. Now they can be adjustable and stay in place properly-
More places to mount and conceal additional parts and pieces. Pressure gauges and hoses, to be precise-
Thoughts?
This is what I cut out on out cnc plasma, autocad files are available for anything I make if somebody wants them.
Here's what I used it for:
The pilot light torch will be attached to the bottom of the propane tank, the distance to the barrel is right where it should be here. I can move and adjust it easily now, too.
I'm pretty sure my friend can get some kerosene for cheap/free through his parents, might just have some test pictures by next weekend.
I've been thinking about anodizing lately, also think my metal shop teacher would be interested in it. My friend has a friend who works in the local refinery, who has offered to get him some rather concentrated H2SO4, though I'm unsure on exactly what percentage.
If only chrome plating was as easy as anodizing
Thanks for the offer, if I get stuck I'll PM you. A friend of mine who went off to instrumentation college a few months ago taught me everything I know about Autocad.
It's a goddamn flamethrower not a sculpture, wear adds character.
Here's a pic of what I'm working with. For the gun, I'm going to pick up a used power washer wand and modify the tip for a thicker stream.
13579, what are you using for a tank? If you want one of these, I could buy another off the guy and ship it to you.
Hahaha
lol ya ur rite lol look at this shit 1911
ud haf to get it reblued coz its so worn and ugly
