This is a little gun I made, I wanted to find out if a standard hose nozzle could take over 100psi. I didn't expect much out of this gun but I was pleasantly surprised. I get about 15 powerful shots at 110 psi down to about 80psi.
I tried making this almost entirely out spare parts the only things I had to but were the 7/32" barrel and the 3/4" elbow.
The main chamber is a old propane cylinder I epoxied a shcrader valve into. That is connected to a 3/4" ball valve, this connects to a elbow that connects to the hose nozzle. I used a hose cap with a hole drilled into it to mount the barrel. I used a piece of golf club shaft to support the 30" barrel. I used an old doughnut shaped neodynium magnet over the golf club shaft to hold bullets inside the barrel, and to hold spare ammo. It fires .177 bbs.

Nice plinker you've got there 
So do you just open & close the ball valve for each shot, to get multiple shots from one charge of the cylinder? Good idea with the golf club shaft.

Very, um... ghetto. But, i love ghetto guns, so nice gun. It would look even better w/ a paintjob

that barrel magnet is a good idea.
its a nice little gun, ALTHOUGH, replacing the hose gun with a "pistol grip" blowgun would increase accuracy and probably flow too.
if you wanted to spend 7.50 more on this thing.

I actually decided to make this smaller on purpose because I have a larger sprinkler valve pneumatic that is powerful but takes to long to pump up, with this smaller chamber its about 1 shot per pump after I'm up to 80psi.
It took me like two hours with some time waiting for epoxy to dry.
