little piston-in-tee gun
Posted: Tue Apr 17, 2007 9:34 pm
Here she is, my new pride and joy. this thing is just as powerful as my much bigger 9 foot coaxial. this baby shoots so fast you are lucky to see anything for more than a second or so. at about 45 psi, this cannon will out preform my sprinkler gun at 130 psi, no joke!
Barrel: 3/4'' SCH40 pvc
Chamber: 1.25'' pvc
Valve: home made piston valve in a 1.25'' tee with a 3/4 end cap as a piston with about 1/4'' thick rubber bolted on the sealing face.
Loading: breach loading with a coupler to cover up the slot.
I designed this to do a couple things.
1. i wanted it to be portable and powerful.
2. i wanted it to come apart easily, so everything is threaded unless it had to be glued.
3. i wanted it to be somewhat loud and be able to scare away the ulta-annoying birds at my house.
this cannon met all all my requirements plus more. this gun can hold pressure very well, it will stay at 100 psi for about a minute before it drops to about 98 psi, which is better than any gun ive ever made. Did i mention that is was powerful and loud?
anyway, enough blabbering, here she is. click on the picture to make them a little bigger.
