Well, with 4 spray 'n prays under my belt i decided to make a pneumatic. I wanted something with the same size bore as my previous small gun (S&P), but with more power, so i decided on making a 1" psiton valve.
Specs
- 1" barrel sealing piston with 1/2" port
-Pilot- 1/2" ball valve
-Fill valve- Schreader valve
- 1/2" female threads for interchangeable barrels
- Barrels- 1/2", 3/4", and 1" burst-disk/confetti
-Operating pressure- 80-100 Psi
my 1st Pneumatic!
- Attachments
-
- The gun with the 3/4" barrel (attached), the 1/2" barrel, and the burst-disk/confetti barrel
-
- Looking down the barrel
-
- I shot this dart through both sides of a peanut-butter jar filled with water, and it continued through the towel backstop and embedded itself into the brick wall behind the towel!!! Needless to say, it got pretty screwed up in the process.
-
- I shot an AA battery at 95 psi and it went through both sides of a peanut-butter jar filled with water, and then went through the towel I was using as a backstop!!!
-
- you can see the hole where the battery went through the towel better in this pic
-
- Just some of the non fruit/veggy ammo i use
Nice first piston, good job getting it to work.
And P.S. im sure you know but a towel really isnt a good backstop.

The gun is so so... compared tot he valve and the ammo! Making a piston valve on you're first try is really impressive, and your ammo is (like always ) great. Keep it up!

I'm really impressed with your first gun being a piston valved one. Mostly, you hear about peoples' first using a BV or modded sprinkler. Good job on the gun and ammo!

Good job on the ammo and the piston, like the others said. I also like how I'm not the only one to figure out that heavy fabric doesn't quite stop a speeding projectile coming out of the barrel of one's first pneumatic. 
Man, that blanket got torn up. By the way, try using a bunch of those little mini-glow sticks that you clip onto each other. I shot a bunch of those out of the CA1 for the 4th. It was good fun.

Ah the patented and rare reverse chamber piston gun. Congrats Im glad someone here had the money to build a replica of mine (unposted as of yet). Top job mate :thumbright:

Impressive, four big bores and I have yet to attempt a piston. Good work, though I wonder how much that thing flexes at the tee's. I don't know if you have any brace blocks in mind but a stress crack (though unlikely with that size and weight) is a terrible fate for a gun. Have fun with it and keep it up.
Finally something to shoot that fabulous ammo you've been building.
The only thing I would suggest would be a sprinkler valve/airgun pilot replacement for that ball valve and a paint job.
Overall, looks solid! Good job...
