Leuk gemaakt :)
Maar met een QEV zal hij nog wel een heel stuk harder schieten.

Further in english:
QEV's open up really fast. A ballvalve, rigged by a spring opens in about 30-60ms, but hand it is much slower (100ms+). While a QEV opens up in the 5ms area. Your fire extinguisher valve, if you are lucky, may open in between 15-40ms.
A QEV would improve the power of this gun by alot.
Also, I believe that the fire extinguisher valve is possible to constrict flow.

Je kan 2 dingen doen:
1- QEV direct aan de tank koppelen (dan heb je idd het probleem dat je iets moet hebben wat erop past)

2-Je hebt dat T-stuk er ook op gekregen. Er staat 1/2" op, dus een 1/2" QEV kan je er zo gewoon op draaien. Je zal de huidige "FE valve" OF open moeten houden, OF aan moeten passen (uitboren oid.) zodat er gewoon vrije doorgang is.

This is pretty sweet, I take it it's fairly accurate? You should do an accuracy test too. I wonder what would hapen to a tomato...

one question how long did it take you to make it? because it looks really nice.
whats your main ammo?

Im interested to see how you fired it. i cant tell if its a barrel sealing piston valve with a fire extinguisher tank, or if the fire extinguisher valve is the main valve.

and BTW your english is just fine.

the QEV's are rated that low because they get used in truck air brakes, and that is a place you don't want them to fail..
