Single barrel preloaded cartige gun

[blind909]

Ok, I have finished my preloaded cartrige gun. All credit goes to Davidvaini, since it is his design. I have a blowgun(the ones you get for filling up car tires) to trigger it, the pipe size for the cartrige is 1 1/4". I use multiple layers of plastic bag. I made an air tant, which lasts about 5 shots, and is made ALMOST completely out of aluminum( I have an aluminum bottle, aluminum pump, but a plastic 125 psi rated valve). The pump is jb welded to the tank, and into the valve. I have no clue what the pressures are yet. Since I am not allowed to shoot anything other than confetti, water, and air, no damage pics . But since its independence day, its perfect. It sounds like a firecracker, and blasts out confetti . Enough with the chit chat, here are some pics.

That is perfect for today! Shiny too. 5 shots a tanks isn't bad either. Nice Job. Hope to see it shooting some real ammo.

And for anyone whose wondering, the blue aluminum bottle is from a sprayer bottle(from dollar tree), and since they are soooo cheep, I probably wont be using pvc or soda bottle air chambers. I can get them in silver, blue, red, and more, and they have standard 3/4 inch threadsd .

Nice, clean design. I like it, now on your next model, why not try for a break-barrel design?

[ondskehem]

I am sorry, but I don't really get the function of this one! Could you exlpain a bit more perhapse?

[blind909]

you hook up the blue pressure chamber to the bottom of the blowgun, pull the blowguns trigger, and inbetween the the coupler and the endcap there are 3 layers of plastic which bursts. all it is is a triggered burst disk.
If you still dont get it, click the link in my signature, and look for Davidvaini's preloaded cartrige prototype.

I think you should redue your picks for your poll answer.. Im not saying Im not without humer,but that answer for your poll is in bad taste..(the last one) Thats just uncalled for.. :puke:

Thats really nice and compact but one question the bottle you used what pressures would you recommend.

[blind909]

I dont go over 125 psi, but thats just because the plastic wye valve(125 psi garden hose valve), but I am sure you could go well over 200 psi. The the sprayer top thing is sh!t, so i only used the bottle.

P.S, here is the LINK
