Holy crap that's awesome! Looks a little like a copper pneumatic... just without the copper. How accurate can you get with those marbles?

Find a local community college. Almost all of em have some sort of course you can take, (not even to get a degree or anything, just to take a class so you know how), to learn how to weld. A few night classes and you'll be ready to rock and roll. 8)

Very nice cannon indeed! What is the lowest rated fitting on it? (It would be then handle I'd assume)
Sadly, I had to vote 'not awesome', since this wonderful piece of work did not leave me in awe. I wish there had been a 'seriously kick ass' option.

Just a moment - am I getting this right?
You actually had it loaded and pressurised when you were conducting work on it, and performing a test?

Jesus - I'm surprised you didn't mess yourself up ten times worse...

Aside from that - I like it a lot, and can barely wait to see it minus the tape.

We need a section for metal cannons round here.

Metal rifle designs look so much better than plastic :wink:

It looks nicely laid out and well made too. I've got to get myself a scope like that. Its a bugger sighting down polished pipe, the end seems to vanish.

You can have a "Right Muppet Award" for testing for leaks with a loaded cannon and for then shooting yourself though.

Mine is probably about the same size and I dumped it in the bath with a few inches of water to check for leaks (and found too many). A pond works fine too if its not too far.

Ps. You have a 3000psi rated pressure hose and blowgun eh? :P

lol ok thanks everyone for the feedback and as i would like to say again the incident involving my hand was an ACCIDENT it was late i was a lil tired (but it certainly woke me up a bit), it was just plain not thinking all i can say is a lesson learned the hard way("DON'T F**K WITH COMPRESSED AIR") and i hope this does not happen to anyone else.

peace all
chaos

Well that looks like a CO2 cylinder stock with a concealed regulator feeding the air chamber but theres not enough visible mechanism to see the air dumping method. Bolt action too.

The question is, whats it doing here?

the better pics have too many mb to send
20 oz off/on paint ball bottle 1/2" ball valve up to rifled 18mm bbl
bolt action breech load. shoots 2.5oz lead bullets @550-650 fps
depending on temp.
load,cock (to the off position) the spring loaded ball valve, charge the chamber between the bottle and the ball (only 6-8 gm of liquid co2 )
turn off tank, shoot!
shoots 5/8 dowell shafts (spears), heavy 18mm bullets, cyl. steel cookie
cutter type, and most fun are: reversed 12ga polywads.
the reversed wad screames out for 40 feet or so then drop quickley to the ground at no more than 100 feet, and reusable
many picts of this prototype and penetration in wood, but too large to send
the bolt has been totally revised in the finished and powdercoated gun.
again pict too many mb to send
