Has anyone taken a Paintball tank at fit a qev + barrel inside the tank? like this

I don't think so. Good luck getting the QEV in there, though.

Bandsaw or angle grind the bottle in half? and Mig weld back together! :tongue9:

I seem to remember someone doing with a sprinkler valve. Hm.

I don't see the point when you could do this:

But on your design when the piston retracted wouldn't the barrel move out of position? BTW im not planning on making this i just thought it would be cool :tongue9:

I assum he expected you to understand that you need to attach the barrel to the tank

and before you ask - he wanted you to use epoxy
there are other ways in which you can do that though... compression fittings etc.

OMG just put a 3 way valve there and there is no need to cut a hole for shrader valve

If you weld the heat may damage the QEV. Not sure how you would do this without damage. The valve would be non-serviceable in that configuration. A Coaxial piston valve would be much better.

As far as cutting and migging the bottle, most modern tanks are aluminum (IIRC), so I understand that migging would be hard. Tig is apparently easier.

Also, the bottle is probably artificially age hardened to something like T-6. Welding would bring that to like T-0, and your new yield strength would be crap.
