so assumeing you had metal threads on it the pvc is strong enough to just screw it in to? meaning making your own threads. I'm about to install one as soon as I can find a good valve and I don't want it to fly off and go through my skull. I wouldnt just screw into the pvc I would use bushing to bri...

it cost me about 50 cents to go from 1-1/2" to 1/2" threaded with 1 flush bushing and then i got a brass fitting for about 4 bucks bringing it down to 1/8" and i can remove that and screw it in to any gun i want to use at the moment

TfAv1228

with that kind you just have to get the hole the correct size, but it is still really not safe. Instead, use an Air Tank Valve(A threaded shrader you have a tire valve) and some bushings to get down to 1/8" then just stick on some teflon tape and screw it in much safer and easy to replace for maybe ...

LIST GO BYE BYE

yeah this is a nice cannon but you should reconsider using a tire version shrader valve they are not that safe because they have no threads and i dont believe are solvent weldable. Use an air tank version shrader valve and reducing bushings its much safer.

The only thing I had to buy for this gun was the ball vavle. My chamber is a 12" x 1-1/2" sch40 and my barrel is 7-1/2" x 1/2" sch(something it fits in the 1/2" sch40 fittings and fits a paintball). The U is made of a 1" 90 degree elbow and inch of 1" sch40 and a 1/2" 90 degree elbow. I pressurize i...

i just keep the compressor on it(there is no real point for the chamber that way) or i unscrew that and use a shrader valve attachment

I just remebered this but about 4 years ago in 5th grade I did a science expiriment on static electricity (pretty damn good 1 too I got second in the county to someone older than me). A leyden jar is pretty simple you just build up static electricity then get the - and + wires close and boom you get...

hmm the words piston valve come to mind

TfAv1228

i would say no spring or atleast a weaker one. The diaphram should not be touching the barrel when there is no air pressure so make sure thats not happening.

TfAv1228

hmm well that diagram you linked to says a sch40 1" T not a brass one so something might not be sealing. You should have 1 place for a pilot valve and 1 place for your air source not each on the same hole. And what exactly isnt working is the diaphram not releasing off the barrel or what?

TfAv1228

ok well first off its called a diaphram not a piston. It should not be tight against the well and it should be flexible if its not flexible it cant seal the barrel or get the air to the chamber. Do you have a pilot valve to release the pressure from behind the diaphram?

TfAv1228

ok throw out the o rings and that one u linked to isnt the same it used a pilot valve to release air preasure and a bypass to increase pressure this one the pilot valve moves the piston with air pressure
