Constructing a Safe Flame Thrower

[dusty8683]

my friend and i recently made a flame thrower that was posted on other forums. it has a tank made from pvc that we pressurize to 80psi, the tank connects to a hose, through a vacuum breaker, through more hose, to a gun made from 1.5in. metal pipe. the gun has a valve where you can open it to spray whatever is in the tank out. we've tested it with water and it works excellent... no leaks... pressure holds. to make it into a flame thrower, we would fill the tank with denatured alcohol and add a pilot light about 8in. away from the nozzel (propane torch). the stream of denatured alcohol would pass through the torch flame and create a massive flame. the vacuum breaker is to prevent any backflow into the tank. does anyone have any other suggestions on how safe this will be and what inherent risks we may have overlooked? thanks

inherent risk: torching your friend or yourself

Society tends to take a negative view of people with flamethrowers. Somebody might shoot you just to be on the safe side.

sounds very cool, although slightly dangerous.

if and when you do it, take a picture of it, I would love to see that thing in action.
