my homemade air rifle - piston valve

[1MrPyRoMaNiA1]

how do you load that thing?

[phonyization]

about how far can you accurately shoot?

i'm thinking about hooking one up to my air compressor which is running on 130psi

[dethmonky3193]

what valve are you using for the trigger?

[Gfabe]

nice music

[zeffers]

Gday mate what did you use as the air chamber? Its a perfect size what is it?

[steeloavenger]

Thats so badass.

[eurogunzskillz]

the cannon in my pants shoots harder!! -.-

[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.

чё пидары амереканские обосрались

[callaghan635]

u should stain the wood

[TheSimonarne]

hope it will becom war between myklebust and røsok lol

[beatslyguy21]

thats fricken cool

[rafix448]

a to jest śmiechowe

[keb4bs]

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

[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

[BROKENSAIN7Y]

dose anyone know a good vid on how to make this trigger system? awesome air gun man

[TH3TON3]

blink 182 i love you man! you little fucker i love you!

[eskamobar]

Does the valve dump all the air at once, or can you get several shots out of it?

[PIZZABAGARN1337]

QEV valve?

[PIZZABAGARN1337]

Make a how to video plz :)

[SuperEnterprise01]

VB..Very Brutal

[lucasfm685]

Tumbs up for Blink 182!

[thesheton123]

can i get a schematic, i want to make something similar to this but there are things i cant see from this video, like the trigger system

[drblueman1]

how accurate is it?

[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.

[LuckyStrike153]

cool musik



[ArchDouchebag]

VB <3

[pachecuss001]

awesome man, i want it the same toy!!!

[Patrick995270]

reminds me of a B.A.R.

[Eddiebayes177]

182 :D

[sSTRE3TDR3EMZz94]

the guy singing the song is an idiot!

[iknowmy3table]

I love the fact that you made this from free scrap, I bet you could increase the pressure even more, the blowgun and hot glue piston seem like the weakest links, but a metal washer backing the rubber could help the piston, and the blowgun, hell they are rated for really low pressures but the extra pressure will probably just make it leak a little, not explode or break, and if you really needed to upgrade it you could get a pressure washer handle for pretty cheap

[ak74u2]

lol im guessing your aussie because of the vb and sweet gun it looks like a shotgun except the handle

[TheBakoom]

@ak74u2 haha you guessed correctly, i couldnt find anything else in the room to hold it up besides the vb can.

[ak74u2]

@TheBakoom lol cheers buddy

[TheDh0ffryn]

@TheBakoom well VB has another use other then being a Visitors Beer!

[s3an9000]

@TheBakoom pfft air guns need a gun license in australia. i'm hoping to get said license soon

[aleexishurrx3]

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

[MrCancerbero]

what music?

[abdulWahab1187]

which song is on background ?

[mxrocks1000]

thumbs up for all the beer

[SketchyAussie]

Awesome gun, epic music, and great video! Some constructive criticism though:

1) If you don't put a groove in your piston you'll get higher power, air will still leak through much slower.

2) Your piston looks like it was made of hot glue, try your hand at casting one from epoxy, it will provide less friction therefore faster opening times. It also won't expand on those really hot Australian summer days (I know this from experience).

3) I recommend you check out spudfiles if you haven't yet. :)

[TheBakoom]

@SketchyAussie hey thanks,i did make one out of epoxy but it was stuck in the brass fitting so i decided to stick with the hot glue piston.

[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. :)

[MrkBO8]

You have to know how to make stuff in Australia to have fun because its illegal to have an elastic band and a paper clip in the same room.

[SketchyAussie]

@MrkBO8

That made me lol. Fortunately nothing improves creativity like a lack of supervision, so there are a lot of great Au/NZ homemade launchers around. :)

[muumimees123]

BLINK !

[Digadogup]

@thebakoom erm lol epic coke zero prop

[TheBakoom]

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

[mcwario13]

@Digadogup ???

[Digadogup]

@mcwario13 0:07 :D in the background

[KneeCapHill]

God finally! A home made gun that's not made out of lego or carboard!

[osama201079]

how we can know from where you shout we didn't see you whihle you are shout

[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.

[bmxrulez4life]

What did you use for the piston? and did it work?

[TheBakoom]

@bmxrulez4life used a hot glue gun

[bmxrulez4life]

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

[GunnerCollins]

@bmxrulez4life its a blow gun he got it from bunnings

[11gamero111]

what's the part that makes the trigger?

[GunnerCollins]

@11gamero111 its a blow gun

[4dipdap]

bunnings??? from australia??

[TheBakoom]

@4dipdap yea

[Letsgetthispartigoin]

How did you make this? Did you attach a CO2 tank? Where's the valve? Is there a valve. :s Yeah, I know these are a lot of stupid questions but I really like this gun.

[marko03033]

is this on spudiles

[TheBakoom]

@marko03033 na

[lemming124]

this is very nice for a first! it's refreshing to see something that's not just a ball valve separating a chamber from a barrel.

[hammachine]

Yeah, I made a pneumatic spud gun myself (out of a small fire extinguisher) and I found that the only thing stopping the gun from working to its full potential was the limit of the pump.

[TheButtonMash]

@hammachine know what you mean, same deal here. I also got a homemade airgun and stock but don't have any videos of it

[hammachine]

Great Job!! What psi was that set to?

[TheButtonMash]

@hammachine it could take about 350 psi but only takes it to 160 psi max cause thats all a bike pump can put out

[TheButtonMash]

ohh holy crap its mitchell lol , realise from your backyard and the gun stock , btw its me collins ;)

[TheBakoom]

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

[xXvapourXx]

dude great job looks nice cant wait to see more videos from you :D
