Me holding my big, white (no that's not an oxymoron...) gun... :-) muahahah
pic11.jpg
Found these in a camera my mom got me from goodwill (I needs capacitors for my coil gun experiment) and lore and behold, they are a PERFECT fit for the .75&quot; CPVC barrel... I only have these two but I wonder what they will do to that plywood board...
pic10.jpg
Compressor gets to 120 but the tire inflater attachment i've been using I think levels off at somewhere around 100 since this is as far as it'll go... (it has a &quot;do not use above 125&quot; though... Anyway, I think his is pretty impressive, but that's me....
pic9.jpg
Shot of my barrels and target board, from left to right: 8&quot;x1&quot; SCH 20 pipe (Its so short, and since nothing is loaded really past the muzzle, I don't think the fact its SCH 20 much matters), 36&quot;x1&quot; primary barrel, and my 5'x.75&quot; CPVC paint ball barrel pipe. I may or may not cut down... And spray can for scale.
pic8.jpg
3&quot; end cap, Schrader valve (a long one yes but for a solid $2 who's complaining?), and my pressure gauge! I spend most my time around this end...

A very nice shot (if I do say so my self) of the front end of the valve, a 1&quot;-.75&quot; reducer, and the beginning of my 5' long CPVC paint ball barrel...

A shot of the valve and the blowgun attached, I could use an air hose but since i work in a garage, it would just get in the way.
pic4.jpg
A head on view of he sprinkler valve from the quick disconnect side...
pic3.jpg
Here is a good shot of the front end equipment and fittings. From front to back: pipe chamber (can barely see it), 3&quot; coupler, 3&quot;-1.5&quot; reducer, 1.5&quot;-1&quot; reducer, about 2&quot; of 1&quot; pipe, 1&quot; male adapter, and sprinkler valve.

My initial valve head design. As you can see a barb would have to be threaded then a tube connected. I find the quick disconnect much more convenient. Also, here is a good shot of the epoxied solenoid hole. Its hidden, but this valve head (and the other) has a guide rod as well... Which is why the hole was drilled to the side.

A nice overhead/forward view of the gun. You can see the sprinkler valve, quick disconnect, the pressure chamber and the pressure gauge in the back along with according fittings. Also as you can see, its in a vice. This thing is heavy man! Oh and the blowgun is set on the vice as well.

That is a 1 inch sprinkler valve. It says so in the thing:
Here is a good shot of the front end equipment and fittings. From front to back: pipe chamber (can barely see it), 3" coupler, 3"-1.5" reducer, 1.5"-1" reducer, about 2" of 1" pipe, 1" male adapter, and sprinkler valve.

:? I am new to this site and see a lot of different air release systems that all seem to be the same three. I have No use for supah valves, air bleed
triggers {which are clumsy, ugly, leak off and get broken off} and such.
And sprikler valves run on various dc battery configs.
You can make a stock sprinkler valve really talk with a capacitive discharge trigger system. Iwill post my designs later today after I figure out how to navigate this site better.

tronhead, just mod the sprinkler vavle. It doesn't take more than 10 minutes, and tools you should already own. And even if you don't, the only real specialized tool you will need is a $3 1/4NPT tap.

You fail to realise the flow of the normal path of activation. The hole is about the size of a pencil lead. Even if that soleniod opens at mach 300 itll still have sh*tty flow. Get a little pushbutton from McMaster if your worried about athstetics. You could always bore out the two holes, get a bigger soleniod, slap a bigger sealing face on there, and BAM! your done with a whole bunch of wasted time!!!
