clip action pneumatic shottie

[whisper13]

I have plans drawn up for a clip action pneumatic cannon, but i cannot figure out what valve to use, and suck other problems. my only other experience with PVC wasa failed hovercraft, so I'm pretty new to the whole pressure stuff. it will be fueled with Co2, because i want it to be portable. the Co2 goes through a regulator valve into a secondary air tank, which will be in-line. the fireing will be electrically actuated. the shells will be fed through a 4 round clip, and the barrel is free floating, or held down with U-bolts. the shells WILL be ejected, with a toothed system that will be illustrated later. the shells will be made out of (probably) film canisters with a sabot filled with whatever i can fit in it. however, i would like your help in finding any kinks in my plan.

y do u need shells? jus tload in the actuall ammo to the clip an djust shoot that then u dont need to make a toothed thing, and for the valve i would use a sprinkler, but i wouldnt use the electric thing, i would just use a modded sprinkler, then u dont need to replcae the batteries and it works even better then the electric component.

i need shells so i can use non regular ammo like paintballs or small water balloons. also, imagine the badass-ness of some guy cocking a paintball shottie and a orange shell flies out right before he shoots you.

thanks for the modded sprinkler idea, although someone will have to tell me how to do that

just go to the how to section of this site and go to "how to mod a sprinkler valve" it have everything right there.

yeah, but shooting paintballs from cannons at people is a very stupid idea as they normally go over the safe FPS limit of paintball guns, and can break bones, masks, and cause other damage

Ya dont shoot them at people even though they are very inaccurate they hurt like a bitch when you get hit.

[iamthewalrus]

they arnt all inaccurate, but yes, they ALL hurt if u get hit.

hence the low pressure regulator valve. all will become clear when i post the pictures. the purpose is not a long range high power launcher, it is a USABLE shotgun style homemade gun. chill 8)

these are some (rough) schematics done on microsoft paint
