it is hard to believe but if its true then wow thats unreal. those fittings are SO thick thats really good. i hope it is rated that high mate thatd make nice cannons.

16 years and 8 months-ish

im from south west vicco.

yeh mate of course there are pressure rated pvc fittings.

otherwise the guns that we make would not be safe and they are.(mostly)
there deffinately are rated fittins. have a look around

there is a way to do that.

or you could have a remote control, servo actuated blowgun directly onto a sprinkler or QEV. that would be simple as hell aswell. just hook the servo arm up to the trigger.

i have old rc systems that i make stuff out of and use servos to move switches and things ...

very nice. id love to build a copper gun soon. we just got a new gas welding kit from the insurance company too lol. wish i could get my hands onto a qev. thats really clean mate. inspirational.
got any damage pics ?

the distance different beer bottles will fly and determine the most aerodynamic haha. make a little wind tunnel even lol.

i think you would be pretty safe putting it in the vise ( valve ) and getting as big of a lever as you can ( as suggested ) and doing that. if you put the nipple in and try to turn the valve you will have almost no leverage at all. as long as you don't overtighten the vise. all it has to do is stop ...

im not sure what level of school you are in so ill just give a suggestion.

maybe something with light. using different glass prisms to bend light and find out about different colors of light bending further than others (blue light bends more than red etc). just a suggestion because its fairly ...

i think that your biggest problem is the slow speed at which you fill it. if the piston doesn't seal against the chamber walls very well then it will take a burst of pressure quickly to get it to seal against the barrel. otherwise it mite get to the barrel and then not have enough to seal and then ...

i just modded a valve that is very similar to that the other day. the black rod on the top is a flow control and i took that out and used the hole from that (made it a bit bigger) to put the male to male fitting into to connect my blowgun / ballvalve onto. and filled the solenoid hole up with epoxy ...

of course the ball valve will work. currently i'm working on my 5th cannon and the last one had a ball valve (others were combustion)

i can open it pretty fast and it definitely works. but for the next one i'm using the sprinkler valve i modded yesterday. i put it onto the other cannon in place of ...

the valve arrived today. i modified it fully and it took tops of half an hour to do. it seals completely no leaks at all. as soon as i can get some new pipe for the rest ill get working and put some pics up. i tested the valve on my over and under which normally i just have a ball valve on and the ...

so get off the computer and go and build it :D

thanks for the fast replys guys. i have decided to go inline. and yeh id like to be able to go out rite now to my shed and make it but i have to get some more parts first. and wait for the sprinkler valve to arrive which was shipped yesterday ...

that is a nice cannon. will look killer with sum paint. the only thing i could fault would be the dwv reducer on your chamber. but other than that nice work mate.

p.s i didnt mean it to sound like i was trying to find a fault mate.
