A little intro :
I've liked weapons since I was a lil' kid, first got a stupid BB gun, modded it to a cool one, then made two or three BB rifles of my own, then made the Railgun, then the M8 N1 (a real freakin' rifle, with bullets and all...), then the M8 F5 (powered by bug spray : both rifle and flamethrower - not very powerful)... well, it's all here : http://fiveseven.xon...n.com/Guns.html

So now I'm thinking air power...
I'm posting my work here 'cause it's pretty related to wargames, even tho' it's a lil' bit more serious and more dangerous than backyard nerfing...
Plus, it's definately related to airguns and you guyz are all about homemade airgunz (rock on !).

OK, let's get technical.
The caliber is 4.5 mm (Magnum)
Barrel lenght around 450 mm
Valve is the kind mechanics use to pump up car tires (freakin' great 4 this kinda job)
The air sys can take up to 18 bar (around 180 PSI ,I think)
I'm thinking usual pressure of 150 PSI

The thing is I don't have an air chamber... I'm thinking about using a bug spray-hair spray can but I don't trust it to hold 150 PSI. So if anyone can give me an idea, I'd appreciate it.

I'm not sure about the design, either. So I'll get back to you ASAP with skeches or something.

So... any thoughts on the chamber are welcome, plus I'm considering not using a chamber but using a constantly pressed car pump instead (hope I have enough air) that would be nice 'cause I wouldn't need valves and all that... trying to keep the design to a minimum...
