My Homemade Air Rifle - Piston Valve




Did this video help you?

MrMiguella: nice work. good to see another aussie (vb can is a give away) getting around the stupid laws we have. probably the best stock for a qev gun on you tube. I'm on about my 10th rifle myself and found that the cheap 1/2 in qev valves on ebay are a bit more compact than the home made ones and are cheaper than buying all the fittings to make one yourself. next project you should do is a hammer valve pcp rifle, once you get the trigger mechanism working they are way more fun as you don't need to refill the tank every shot. although the qev dumping all the air at once gives way more power.

Rick Z: well ill through some shrimp on the barbie ....

Hill Billy: hahah VB can

Павел Полищак: your music is cool

Anderson Freitas: ei oque vc usou como gatilio

zakamooza: wow nice! check out mine

MISTERCLASSIC10: que es lo que usate como gatillo

Dylan Williford: This music makes me feel gay. Like homosexual.

MISTERCLASSIC10: that's what usate as trigger

Lobelialapse: I like the stock you made, very cool. It must have been a labor of love. I would like to ask you a question and hopefully get a little help. I've built several air rifles. I've used ball valves, sprinkler valves; electric and mechanical diaphragm, and poppit (hammer valves). The one thing I've never been able to do is get a barrel sealing piston valve to work with a small air nozzle. They just don't exhaust the high pressure quick enough. How did you get yours to work? I've opened the ports inside the valve body. I've turned the center of the valve pin down to almost as thin as a pencil lead. I added holes at the center exhaust transfer ports. I drilled out the bottom of the valve and cut the lower portion completely off but it still won't do the job. If you can share some advice it will be greatly appreciated, Thanks

1colewade: thats freaked up! lol

Lucas Felske: Tumbs up for Blink 182!

Digadogup: @mcwario13 0:07 :D in the background

BaKoom: @TheButtonMash hahahaha hows it going? i just started making a new stock it looks more like a thompson, and i found that welding place.

wyz2285: very nice, But the valve´s pilot volume is too big, for better performance try a o-ring piston or reduce the pilot volume.

dethmonky3193: what valve are you using for the trigger?

jhon dave: hey.. you use hand pump??

Richard Bird: VB cunt

LuckyStrike153: cool musik

jasper wortelboer: im gay 1

bmxrulez4life: 0:09 Dawn thats a nice stock :) Where did you get your trigger/release from?

Gamemaster411: Imagine Julia Gillard's face when she sees this and realises that the current gun laws in Aus aren't keeping us from arming ourselves.

keed: i cant seem to find the valve that you are using, what is it called?

SuperEnterprise01: VB..Very Brutal

SketchyAussie: @TheBakoom Try spraying some grease on the inside of the fitting before you pour the epoxy in, after it dries you'll be able to pop it out easily with a few hammer taps (I put mine against a piece of dowel in a vice and tighten it until it lets go). :) I use a can of white lithium grease, you can get it pretty cheap from bunnings and it works wonders. :)

griffin conner: thats fricken cool

JoelHackett: at last a good song

supermotardmario: cool but dont use real pcp pressure for it ! 3000 psi will blow it right up. you are probably smart enough to figure that out, but you never know

Nwest82: nice, can't wait to see it completed, have you fired it through a chronograph yet? if so what were the numbers like? I've been really wanting to a PCP air gun build, but have a lot to learn about designing a valve/piston system that will function correctly and not dump all the air in one shot. Nice work, Keep it up! Great job on the stock BTW.

noobeable: tutorial please

Riley Stock: straya cunt, nah good job mate im hoping to make an airgun like this, this weekend, where did you find the valve, its awsome

Tommy Sands: too weak

BaKoom: @marko03033 na

wallyson santos: fodao

steeloavenger: Thats so badass.

GunnerCollins: @bmxrulez4life its a blow gun he got it from bunnings

jhon dave: can you show me how did you build your piston, and how its work..plzzzzz

D Elliot: I can't stand it when technical videos and how to stuff always come with a soundtrack. Annoying.

simone cosentino: wowwwwwwwwwwwwwwwwwwwwwwwwww

harry goodman: oi can you tell me how a piston valve airgun works please, Thanks

Rafał Matysek: a to jest śmiechowe

Abdul Wahab: which song is on background ?

Garrett Faber: nice music

aleexishurrx3: blink 182 makes the vid good lol and whats my age again peoples

clarkespearo: Or Very Bad, Vile Beer, Vomit Bomb, either way it tastes likes crap and is only good to use as a target haha

BaKoom: @Digadogup hahaha i got that from a friend who use to work for coke

PIZZABAGARN1337: QEV valve?

GunnerCollins: @11gamero111 its a blow gun

Landon Brecheisen: Nice I am making a gas blowback simi/full auto airsoft gun it will be useing 300 psi and i am making 50 round mag can't find any springs for airsoft mags so am ordering spring wire and making them. I also have to order a barrel cause I don't have any pipe that will fit a airsoft BB perfectly. I will put a video response on your video. My dad has a shop so I have a bunch of tools for my use + tons of parts.
