Introduction: PVC Air Gun 1.0 Cal
The total cost for it was about $40
It uses a twin valve mechanism so it can store up to 12 shots without me having to refill the air in it (it has a small compressor mounted on it not pictured)
It shoots anything you can fit down the 1 inch barrel.
It holds up to 220 PSI but I usually store 80 PSI in it to avoid damage to the seals

power industrial, you have to find out the best air compressor for your

hi i was woundering if any one could explain how this works to me. My airgun i made was alot more simple and it was only a single shot!!!

i dont think i can describe it fully in a comment, try see mine. exactly same mechanism but i use a soda bottle, so i cant pump it to 220 psi as this gun here, so its less powerful. only 100 max, but thats enough coz the volume is large and i get more shots before the pressure gets too low. but seeing that your comment here was from last may, i guess you probably had figured out the mechanism already

this is to all you guys that have made one, how do you charge your rifles? and how many shots can you get out of a fully charged gun??, how powerful is the second shot because i would imagin it would only be half as powerful as the first shot

My rifle now has it's own portable 12 volt air compressor strapped to the front, with a power lead going into my backpack, where I have a dry cell car battery (1/4 size and weight of normal battery).
The second shot is about 90% power of the first, but still enough to penetrate through sheet metal, with a metal marble. it decreases from about 90% to 70% in the next shots, but all shots but the last 4 (the gun can usually do 12 at 80psi) can go though sheet metal.
pretty damn powerful, and way more now that I have the mini portable compressor

Ha i have made almost the same exact thing. I was going to post a video of it but my video camera wouldn't connect to the computer. But good job. I would recommend have the reserve chamber a little bit bigger pipe. Mine is 1.5 inches. I like how you laid yours out. But i did post pictures of my cannon.

nice gun, and thanks for the comment. yeah i may have to make it bigger, but when i am firing marbles at 80psi, they all still go 250metres plus.

Wow i have a barrel that can't fit marbles(i am assuming you have 3/4 in. PVC pipe where i only have 1/2 in.) but that is ammazing
