Here's a little simple sprinkler valve cannon I made for a family friend. I spent zero dollars on, but I'm selling it for a nice profit.

Nothing really special: interchangeable barrels, pressure gauge, and a push-button trigger, but it's pretty nice for what it is.

Nicely done :) what did you use as an air chamber?

As this is a commercial venture though I would have included a 150 psi pop-off valve.

Thanks, its an aluminum fire extinguisher repurposed for my use

I have a spare pop-off i could mount on it, but I know that my buyer does not have access to any high pressure sources to overcharge it with

A simple "do not exceed 150 psi" stencil would be a safe disclaimer, just in case :) not that the tank would rupture, but that sprinkler valve could easily become a cloud of sharp plastic shards.

How did you attach the fire extinguisher? I have one and I want to use it for something like that. Thanks.

Good call JSR, I'll be sure to throw some warning labels on it before it leaves my hands.

@8ton, I just epoxied it into a 1" PVC male adaptor. It looks pretty clean and is great for low pressure, but I wouldn't recommend it for anything over 200psi
