its still incomplete, i found most of the parts in an abandoned truck yard near my house also found the wood for my stock there aswell rest of the parts i got from bunnings.

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.

that's what usate as trigger

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
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,

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.

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.

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

Author supermotardmario ( ago)
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

Author eskamobar ( ago)
Does the valve dump all the air at once, or can you get several shots out
of it?

Author iknowmy3table ( ago)
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

Author Joey Asnicar ( ago)

Author Paul ( ago)
@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. :)

Author BaKoom ( ago)
@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.

Author Paul ( ago)
@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. :)

Author Paul ( ago)
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. :)

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.
