This is awesome. been trying to find a way to make a semi-auto HPA blaster. Have there been any updated versions to this design? If there is, it would be great to see the changes you've made.
PFenixTX the revisions have merely taken the form of normal shells and been automatic. They were also more expensive, so I dare say you wouldn't enjoy the price tag.
Spectre's Nerf Workshop Oh automatic? like you Death Blossom? That's pretty cool. still a bit curious on how you did it, but it does sound like it might be very expensive. I'm more of a semizauto guy anyway so ill probably stick with that if I ever get around to making something like this. btw, what do you mean by normal shell? do you mean just using 1 blaster shell rather than making a new one with 3 blasters like the this setup you have? Would be interested to know which blaster shells you recommend if this was the case. Would rather use 1 shell rather than Frankensteining one together.
I don’t understand the piston part, do one side of the T run straight to the front of the piston or to the end, from what i see there’s to lines running from the piston to tank?Can i have a draft of it of the lines?
Mister Bubs the circuit is still pretty simple. From the MJVO-3, the line splits and runs to the piston and the firing tank. At the piston, the line splits and runs back to the firing tank via a check valve. The check valve stops the inlet pressure from the MJVO-3 from interfering with the dump cycle.
Mister Bubs most do. Mine are single acting, which means that it returns by itself. So yes, in my system you only have to connect one end of the piston.
Hey there. So I understand your whole assembly except one part.... when the air comes in thru the trigger into the firing tank, how does the tank pressurize If the barrel is always open? If I recall, there is only the Quick exhaust valve to the far right(which I assume is for leaking the tank) the actual tank, and a direct link to the barrel thru conduit pipe in that area.. Did I miss something?
I have been inspired. 2 questions, where do you like to get your QEVs, And, at 4:03 you mention 20mm pvc. I'm assuming that this is Australian standard, but are we talking pressure or electrical? Thanks for the insight
Yeah. I'm trying to buy the cheapest things to see if HPA is something I would want to do more of in the future. Would there be a cheaper alternative for that QEV?
Why would the QEV suddenly release the air in the tank when you close the circuit, the pressure inside the circuit would just stay the same (Also, just asking, if I make something similar to this and put it on my video can I credit you?)
epicnerf1 the trigger is a 3 way 2 position valve. When the trigger is pressed it vents the pressure between the QEV and the trigger, which pulls the diaphragm inside back and opens up the exhaust port.
If you have to ask, you haven't done enough looking yourself. Sincerely, Google is your best friend. I literally mention everything that is in the build in the video, just take notes and then Google it all.
+Spectre's Nerf Workshop Looks great! It would be really helpful if you could provide us with some links to where you bought all of the internal components.
Swaggy Melbourne Operator that'd be all well and good if I could remember where I bought the piston, if it's even still available. The rest of the stuff is available from Bunnings or pneumatic suppliers.
I'm ashamed of how often I giggled when you said "Nipple"
Seriously wanted to know how this thing worked though, it's crazy.
Jesus Christ man, you're a genius! I saw this on SBNC a while ago, and I'm just blown away.
So, that is just about the coolest thing I've ever seen.
Mike Glenn the NERM likes the Baron! 😀
Awesome, just awesome. Feels like I wanna make my own HPA rifle.
OH THANK YOU, I was gonna do some crazy shit with gears and springs and prob v bad fire rate control, your awesome thanks this is so much simpler
Far out dude, I don't think there is much Nerf left in that Nerf mod! hahaha amazing
I spy barrel break bits! My mind just went places...
Before the beauty of supercores lol, you definitely had to make do with what you had.

PFenixTX the Cent shell has plenty of real estate for everything you'd need for a semiauto build. That or the Stampede.
I was so looking forward seeing the thing moving, but then the video ended... please, at least one cycle!
theCJoe It wasn't pressurised! I built one for Drac though, and when he FINALLY gets around to doing it you'll see how it goes :P
Spectre's Nerf Workshop nice build I love the name and paint

So I only need to connect one side of the piston?
Do your piston have to sides?
Mister Bubs most do. Mine are single acting, which means that it returns by itself. So yes, in my system you only have to connect one end of the piston.

epicnerf1 the quick exhaust valve is normally closed, the trigger then opens the valve to fire all the air out through the breech/barrel.
I have been inspired.
2 questions,
where do you like to get your QEVs,
And, at 4:03 you mention 20mm pvc. I'm assuming that this is Australian standard, but are we talking pressure or electrical?
Thanks for the insight
Sir Benny I get my QEV's from Fittings Express. The 20mm PVC is electrical conduit, purchasable at Bunnings.
Spectre's Nerf Workshop
Sweeeet
Damn. That 1/2 inch QEV is expensive!
person guy yeah, I've moved on from using 1/2 inch QEV's to magnitudinally more expensive projects. Death Blossom was one of them.
Yeah. I'm trying to buy the cheapest things to see if HPA is something I would want to do more of in the future. Would there be a cheaper alternative for that QEV?
person guy a 1/4" qev or a 1/2" Ebay equivalent of the $9 variety may work, but no guarantees on its safety factor.
person guy yes, very easily. You wouldn't need the piston then, in order to make it semi auto.
did you make the piston you're using to cycle the action or did you buy it, if so how would i got about getting one?
Why would the QEV suddenly release the air in the tank when you close the circuit, the pressure inside the circuit would just stay the same
(Also, just asking, if I make something similar to this and put it on my video can I credit you?)
Mister Bubs the 3 way 2 position valve, when closed, vents the pilot volume in the airlines which allows the QEV to fire.
Sure, this build is well known enough that you'll get told to credit me if you don't :P
But then, it's not like the whole world watches your channel
Mister Bubs but a lot of people saw this on SBNC. So yeah.
So only the people in SBNC
How does the QEV know to actuate? Does it have a certain pressure it detects to fire or is it done up some other way?
epicnerf1 the trigger is a 3 way 2 position valve. When the trigger is pressed it vents the pressure between the QEV and the trigger, which pulls the diaphragm inside back and opens up the exhaust port.
Much prettier on the outside.
Plz more vids
is the MJVO trigger always closed or always opened
Legacy knight 408 the MJVO-3 is the always open version, the MJV-3 is the closed version.
thx for the quick reply
I know this is old but can you make a parts list im trying to replicate it
If you have to ask, you haven't done enough looking yourself.
Sincerely,
Google is your best friend. I literally mention everything that is in the build in the video, just take notes and then Google it all.
So the piston opens and closes the breach?
Is this channel still alive?
Blasterworks yeah, I'm just lazy about posting.
Could it use katana magazines?
Yes, but Katana magazines suck so you should get some of Coatduck's Vorpal magazines made instead.
Can you link us to the QEV you used here?
Trigger QEV is a Clippard MJV0-3
Where can the trigger be found
Eddie David Google it and find a pneumatic supplier that is close to you.
Thanks
Is it a NJV03 or is it called something else
MJVO-3.
#bangsundaysesh?
Darcy James this was recorded Friday, lol.
