he find any thing he need in a plumbing store(lucky guy ,i can't find them in my city,so i do like wyz2285 epoxy+ epoxy+epoxy ...)
:lol: well that´s what I do normally, but when sometimes I got lucky and find precious parts, I buy them with any price. And now I found some online airgun/paintball store that sells to my country with a reasonable price too :D

i told him, but he doesn't interest much (his English isn't good to :( )
and we dont have any forum about gun or air gun (that 's illegal in my country ) he post those photo on his blog.
I'm not saying you stole anything, you said explicitly that it was someone else's project :) just a shame we can't see more details.

These things are technically illegal in Australia but we have plenty of Australian members on the forum, you just have to use some common sense and not do anything stupid with your creations ;)

Well, water is practically in compressible in this context.

When it is said "water pressure" it's meaning that the force on the water from whatever means (eg. while oil isn't very compressible, it can be put under substantial amounts of force from something like a hydraulic pump) is amounting to that amount of pressure.

If a pipe fails at 50 bar "water pressure" it will also fail at ~50 bar of air pressure. The difference is a pipe rated for water use is intended for well...water use. Due to the incompressible nature of water a failure tends to have low energy, even at high pressures. Much higher energy involved in a pressurized gas at the same pressure

On the contrary. Water is very easy to pressurize and it will even pressurize itself if you get a lot of it in one place (see: hydroelectric dam).

What CAN'T be done is compress it.

Compression = deformation under pressure.

Although really, even that is BS. Water (and everything else) *CAN* be compressed. It's just very difficult to pressurize it in a meaningful way so it is treated as incompressable for normal applications.

There you go...

What you meant to say is:
It's very difficult to express-urise myself in a meaningful way

In Canada we can get brass fittings at Auto supply shops and Home Depot.
Places like Metal Supermarkets are pretty much worldwide I think and they have all sorts of metal in various configurations.

Kinda hard to get offended by something BTB edited out

Those are some nice rifles! Any details on them, or did I miss them earlier in the thread?

@ dahakka and some senior members that somehow missed this:
Rule 2:
Discussion of shooting anything at any person and/or animal is prohibited, and may result in a permanent banning of your account.
This is just one of those rules you agreed to when you joined this forum.
:wink:

What you do outside of this forum is no concern of mine.
However on this forum the rules apply.

Yeah sorry Brian, didn't mean to cross that line. If you want my full explanation as to what I meant let me know.
