Need help finding a CO2 cartridge

[hydin]

I have had a project in the works for a few weeks, and I just cannot seem to find the base part of it.

I cannot find the main cylinder portion to this bomb (seen below) in any store. I thought maybe paintball canisters would work, but they are the wrong shape and still pretty huge.

Anyone have any ideas where to get a cylinder like this, or if there is another type of compressed gas cylinder besides co2 that I can look for?

I just really dig the steampunk look to it.

The other cylinder is just a normal sized co2 from a pellet gun, and some wrapped wire, and a pressure gauge and I am 90% finished with it. I just need a button, some sort of connector for the main cylinder to screw into, and a button. I just can't find anything this sized.

Any helps appreciated.

What about a watr gun tank?

Yep...

We need a smiley for when you smack yourself in the forehead.

I have worked on this for about a month and a half, and not once did I think "Watergun!" despite wandering past them at least once a week while shopping. I reckon I will be doing some more shopping tonight :lol

Any ideas on the little connector doohickey that the button is on?

Have you tried looking for those mini fire extinguishers that are often seen attached to the inside door panals of street racing cars?

Those I did look for, but I didn't have any luck finding one with the right looking bottom piece. I was hoping to keep the same basic design as the drawn bomb, meaning the rounded bits.

Plus I wasn't entirely sure on how to empty one of those things without making a huge mess

Hmmmm, looks alot like this...

Fenzy M3 air tank. Also used as the fuel bottle for the Nostromo incinerator in "Alien"

Wow that is close!!!!

That is... well, pretty much what I had in mind for this. It's nice to know it exists out there somewhere

Thanks for the lead!

CRAP

All the local stores have taken the water guns with the tanks down.

I may have to find that tank shown above...
