my new copper qev cannon 99cm barrel, 76cm chamber, 3/4 qev (that and the 22mm to 3/4 bsp's from cornish) all 22mm ballvalve piloted with the idea of how to pilot it taken from jim/lsd's shotgun and will shot 150 pages into an argos catalog at 100psi

very nice very sleek i allways love a good copper gun

Nice gun, but how does it shoot? The pilot leads to a dead end, as far as I can see.

If you get a pair of tweezers or a valve tool you can reach inside a schrader valve and unscrew the poppet valve.

What you're left with is essentially a tube and if you close the ballvalve before releasing the pump head the trigger port air is trapped.

Good stuff Leeshad

Really? Hmm, I might have to see how that works sometime. So it's basically a shrader, but not one way, so it's like a quick connect in the form of a schrader valve, am I right?

Its just a hollow tube that can be connected to a pump once you've taken the valve bit out, I'm not entirely sure about quick connects (don't they have something to seal the end when its released?).

OK, I thought so.
A male quick connect is just a hollow tube machined to fit inside female quick connects, which are sealed.

Great job leeeeshad. What pressures do you normally use this at? I use one of my marble guns, (1/2" QEV into a 1/2" type M copper barrel), routinely at 150 PSI and it almost sounds like a gunshot.

BTW, are you in any way related to the joannaardway of these forums? She said she had a brother who made a copper gun with compression fittings like that quite some time ago...

No - leeshad isn't my brother.

My brother goes by many internet names, but the one that you're most likely to see is Ragnarok.

He hasn't built any cannons for a while, but you'll know about it when he builds the next one. It'll be (if he sticks to his designs) reasonably impressive.

no , no relation, i use it at abought 110psi because thats as high as my pump goes, yer sounds like a gunshot so i need a silencer to use it in the garden, joannaardway, are you coming back onto uksgc?

Joannaardway is a girl?
If so thats awesome.

Btw, nice cannon

I would have thought it had been fairly obvious!

Yes, I am one of the few of those rare female spudders.

Gosh you're probably tired of answering that! That's, what, how many times I've heard that?

An innocent mistake, though, seeing as I can't find a legitimate reason for a forum member searching for another one's gender.

theres a video and damage pics here, http://www.uksgc.co.uk/forums/index.php ... entry13555
