It's pretty simple with off the shelf parts, all you really need is a 5 gallon metal tank, a backpack frame, some compressed argon (or other gas that's non-flammable), a welding regulator, a blow torch with extended reach nozzle, and a trip to Home Depot for some pipe and fittings

The link is missing sir.

Here ya go!

Will CO2 work as the gas? I have several CO2 tanks.

Yeah, any gas that is non-flammable / inert will work... WW2 flamethrowers actually compressed their fuel with propane, which they then fed their gun's pilot light from. I erred on the side of caution and decided to use an inert gas to compress the gasoline in the main tank with.

Just don't use compressed air.

Scary as hell - I think these things were designed as much for the psy-ops effect as for the actual damage they inflict.

Charge it with aviators breathing oxygen. Nothing bad will happen, I promise.

There was a how-to with videos for making one out of pvc pipe also.

worked well.

Using PVC scares the shit out of me... I've seen the same video, kid used PVC tubing in a giant "0" to hold denatured alcohol and pressurizes it.

I would never use PVC as a pressure vessel for gasoline, I know people make spud guns using it, but we tried making a small PVC tank at first and tested it with water and compressed air and at about 80-90 PSI it failed and blew apart! Also, the kid taps threads into the PVC pipe for ports, which is also a great failure point waiting to happen.

Use a metal tank rated for those pressures or don't do it at all.

I saw a PVC air mortar blow up and fuck up a couple paintballers. Big shrapnel nasty stuff
