I want to build an air gun that has a short pop of air so i can have multiple shots so 5 - 7 shots before refilling and im not sure how the airgun actually works, because my understanding of a QEV valve is that it lets all of the air chamber out at once and i want multiple shots like this video underneath this

In order to construct that gun you must first pour exactly 2.6 liters of cement into a bucket. Drill a hole through this cement and know you have completed chamber. Super glue a rifled, 50 cal barrel on and don't forget a valve. your almost done. Fill with argon and click finish.

Theres a link at the beginning of the video you posted, did you watch it?? You need to do some research for yourself here at spudfiles. We dont like to spoon feed! At least make a little effort and I'm sure someone will help. Good luck!!

i know how a QEV valve works right and the piston valve and the pilot because of wyz2285 but im wondering when you press the pilot valve does it keep letting air out if you hold you finger there because im trying to figure out the trigger system as well thanks bud for posting :D

While we are here to help we are not here to be your searching slave or spoonfeed you. If it is apparent that you have done some research and are willing to put in a bit of time and effort to try and understand things, we will happily help you. If you come here demanding blueprints to designs without bothering to try and understand things, we may decide not to help you. It's up to the individual member.

I suggest you adjust your attitude. It does seem as if you know partially what you're talking about, you just lack a bit of experience with the designs in question. Going through topics in the pneumatic showcase section is a good idea and will help you understand the fundamentals of valve designs; you don't need to actually have a QEV to know how they will work or how to make one work semi-auto. There are a few recent designs involving slide valves that will help you out.

If you want multiple shots from a chamber without refilling, I suggest you look in to hammer valves.

In case you've been using the 'quick search' (which is hopeless) instead of the advanced search, I'll link it here for you:

GOD DAMN IT :evil:
What was you expecting?? A detailed tutorial plus scaled blueprint?? I HAVE MY LIFE TOO.
You think you only need a plan, you need MORE than that. With you experience, you won´t be able to build it, even if you have the plan and parts.
You are not the first who tried to make a replica of that gun. But I haven´t seen anybody that was able to make it, and most of them are more experienced than you.
Help a newbie to even a slight advanced level is difficult in real life, there is noway to do it just by messages.
