LOL @ water heater explosion. I daresay you are correct in regards to the re-visit.

Mythbusters tried to make a steam cannon, and it failed dismally.

In Australia, you cant just walk into a shop and buy paintballs, and the places you can usually make you buy bulk (1000 at a time, at a cost of about $225). At least I think you cant just buy them from paintball arena's because Paintball markers are classifyed as firearms in my state, so logically ...

I hate dodgy firearms laws in Australia, specifically Victoria, because we cant have bb guns or airsoft or paintball, unless you got a %^$@*&g million licenses. We don't need the devil to bring Armageddon unto us in Victoria, the State government has done a good enough job of it.

If I could own that legally in Australia, I would gladly sell my family. Very nice job.

Hello again, I have a few of questions:
With the garden-hose valve, what kind of flow should I expect? Why does (almost) nobody use these? In my limited experience they have OK flow, and I don't expect more then 1 shot from the chamber. And what is a hammer valve and how does it work? (Google was no ...

With a 7mm barrel? I don't know, there was that one guy I heard about in a mining shaft that got a 30 foot steel rod blown through his head and lived. Obviously, it was a rare occurance, but I still wouldn't want to risk having a half dead bunny flopping around my garden moaning with a a nail ...

Yes, your very observant Tom. It has excellent flow, much better then a blowgun but it was intended for water, so no guarantees. It works well, no leaks thus far. And Jack, yes my ai will be offset somewhat, but I am hoping to negate that through a tight hold, the overall weight and the bipod. Even ...

How so? No problems for me.

Any feedback? I would like to know if I'm going to kill myself before I build it. I will get pvc rated for 160psi for the chamber.
In regards to my ...

I hope this is a helpful post.
umm...i would have to disagree with PVC Arsenal 17
soda bottlesare not dangerous if you use them under 110psi
i have been useingthem for all but 1 of my guns, i love the soda bottle chambers they are cheap and they ARE RELIABLE.


Yeah, but it's hard as hell to keep ...

So, I have made a prototype of this, and it was really horrible. I could only pull about 40psi with a hand pump (2.1l capacity). The hopper I made worked OK, 2d pictures don't work because I used a heat gun to bend the pipe away. So to load the chamber it was essentially "Rock'n'cock". Problem was ...
