Tiny QEV

[demilus]

I was fiddling around with my paintball gun, and I was about to install a QEV in it (makes the bolt cycle faster, among other things), and I thought to myself, "Hey, this is a QEV. QEV=Cannon!" This could make building a mini pneumatic cannon quite easy. What do you guys think?
The only thing I could think of is how to trigger it.

Easy enough, fill and trigger through the hose end.

Problem is I don't believe ion QEV's bother threading the exhaust port so it would have to be a fairly improvised connection to a barrel.

Might be ok for a bb gun.

how big are they?

This has been tested IIRC and the ION marker QEV is way too small to allow great power.

i think it could be decent for launching small blow darts at decent velocities if the pressure was around 120 psi.

I have and sell 1/8" threaded QEVs for $5

Where can i pick some up? i feel like 1/8 inch is too low of a flow for even a .40 cal blowgun. mabey a BB gun?

the minimum i would use for a bb gun would be a 1/4"

PM me if you want one. And they pretty much are only useful on bb sized ammo.
