sorry was confused as everything was "glues in place" Except for that part i see.

preloaded with a shirt? I don't think i follow how this works. Something has to move in order to allow the air to escape in the barrell? Or is that delrin "flexible enough" to make this concept a diaphram?

As you can see in the picture i'm considering cocking the QEV at a 45 angle, to keep the inlets to the chamber and the barrel on the flat sides of the cylinder.

Was thinking 3/4 Male NPT on the QEV going to both pipes.

Then another at the Pilot port of the QEV to get the connection there to the ...

Working on my Model,. Trying to keep in mind the shape in the end. Does it matter "where" behind the projectile the air enters, so long as it enters behind the effect should be the same?

The reason i ask is because i'm having trouble figuring out how to make things fit and approach att he "right ...

3 9v batteries. I think that causing the honking. I need to use a blow gun, to pilot it faster.

just cobbled together a proto with a 14" long 3" diameter chamber, and a 10" long 3" diameter barrel. Using a 1" sprinkler solenoid valve. No pressure guage so i have no idea what kinf of PSI i am working with. 25 bike pump pumps :) doesn't go far. (Maybe 25-30 feet), plus i was shooting a polo ...

wizard what kind pressure are you using, in how big of a chamber to fire?

I used a female stabilizer from Palmers Pursuit to connect my HPA tank to my launcher and then used macroline to plum the air into the chamber. Its all rated for standard full pressure HPA tanks on paintball guns and the stabilizer lets me bring the PSI down to 100 where I wanted it.

So, it might ...

like fastenal, grainger, etc?

NPT

Mixinf NPT and NPTF won't be a problem if teflon tape is used will it?

Thanks,
there are 2 primary goals. 1. Make a tshirt cannon
2. Make it looks like a flintlock pistol.

I have friends who can help me make bent pipes. Its more of a question, what materials might i use if i'm going for high pressure/small chamber setup? If i use paintball bottle w/ HPA, I might want ...

Awesome.

Thanks for the link. I'm still pretty unfamiliar with CO2 bottles. What kind of hoops will i be jumping thru to get the to mate with whatever 3 way solenoid i get?, and for that matter, If i want more control over shape than pipe might provide, can i use some other (shapable) pipe system ...

Pneumatic QE-04 3/4" Inlet Port Air Quick Exhaust Valve

The link works for me. ITs one of those actions with more than 10 available.

This what i am looking for in a QEV?

I can't read Gasses/Liquid schematics (yet )

That's what I was thinking.

What are CO2 Bottles usually pressured at? Any suggestions on the size of the chamber i would want to work with? Concerning fitting these all together. I'm guessing the Pilot Port on the QEV can be small since its only usd for filling, and the 3 way aswell, its the 2 ...
