My Pmag is finally finished!! Review & Hi-res pics!!

[Shingo]

I was wondering, you know how the MPA-3 has an exhaust port... can you take that exhaust and redirect the excess air to push the trigger back forward. Like a return trigger assist. Something like this:




That air has to go someplace, why not put it to good use? Any thoughts on this? Does anyone know how much force that exhaust can produce?

Ok slade, you win . I'll cut another length of hose like you said, and try it w/ no QEV. But like Pneumagger was saying, if I could only get my ULT tuned...it shouldn't matter so much.

hey, hey, whats with the rolling of the eyes...? i dont feel very appreciated

actually, i realized that since the MSV-2 uses a lever and therefore has a lighter pull but a longer actuation distance, a QEV could have a more profound effect. still, the best thing to do is to test multiple options yourself, and if you do use a QEV, mount it closer to the cylinder.

i know the MPA-3 has a port, but its not exactly an "exhaust" port. its for air to escape when the piston goes forward, otherwise the air would have to escape through small gaps, such as between the piston and the washer, or the washer and the body of the actuator. adding the hole allows the air to vent and decreases the time required to actuate the valve.

what you are thinking of is most likely the exhaust ports on the MSV-1, and using that air to actuate a second cylinder doesnt strike me as that great of an idea.

[Shingo]

It was a thought. Since most PnueMag Mods use a 1-2 mm trigger pull, you wouldn't need a lot of force to push that trigger back forward. Also, was thinking of using the frame itself as the housing for the actuator. only need drill another hole on the frame, drop in a small rod or even a ball bearing as your ram and seal one end of it CT2 Hose Barb where the hose would connect to.

But, it might be more trouble then it's worth.

[Pneumagger]

2 things...

There should be no air coming out of that hole. That is to vent the piston if it extends too far to a certain point. The piston shouldn't be extending that much...At least mine doesn't and it works real fast.

Why would you want a reactive trigger? Not many places allow bounce like that. If your going to bend the rules...just tune the frame for full auto.

^^^ looks nice

**Update**
Just got my emag on/off last night, installed it and brought it to the proshop...fired it side by side w/ the owner's heavily modded Shocker (set at 20 bps ramping). As soon as I had the LPR dialed in, the mag was OUTSHOOTING the Shocker, by a fair amount !!! I'm gonna get a vid up Monday hopefully, and I'll need a goldwave, but it was well over 20 bps. (ok, technically cps, as it wasn't with paint yet, you nazis...but it WAS full cycles, and I'll get a vid up w/ paint ASAP).

...another update w/ pics and vids coming soon

[surfbum]

quick question:
is the emag on/off the same as the RT on/off just with the quad o-ring or is there another difference?

[Pneumagger]

the Pin is alot shorter to give snappier reactivity

[wjr]

I think that the pin is differant.

Hey shorty, did you buy the emag on-off from pneumagger? I sold him one a little while ago... just sort of curious.

And are you saying that it shoots faster with a more reactive on-off? I take it that you were testing it with a ult before.

[Pneumagger]

wjr...
I still got your on/off. He picked up a new one from AGD.
I tested with both the ULT and my emag on/off side by side. I never posted that video. I cant recall what that video up there has. I'd lean toward the ULT vid though.

Shorty...
All I can think is either our on/offs are slightly different, or maybe the sear stop is coming out. I'll measure my pin at work monday and see what I come up with.
When yuo take it to the shop, see if you can figure out how to test the LPR ouput. the 3way shouldn't go over 150psi and MPA-3 & QEV should be good to around 200psi. Pretty sure the hose can handle that. But you really shouldn't need more than 80psi.

[shorty24]

All right, I'll see if I can figure it out. I know the sear stop isn't coming out, I've kept an eye on that the whole time. Handily enough, we have a set of digital calipers at work, so I'll measure my pin too, and see what I come up with. I'll see what I come up with on LPR output when I go to the shop Monday, and get those vids, too.

/I think Pneumagger pretty much answered everyone else's questions...

Other than the trigger return, is this drawing accurate for the set-up? I've looked at the other threads, but this drawing makes sense to me and helps provide a better sense of the lay-out required within the frame. Would an Eclipse QEV work as well? I think they are smaller than the Clippard.

[shorty24]

^^^ more or less...

If you mean the ULE milling, yes, it is milled around the sear guide channel. No problems at all, there is still a raised section in which the sear pin itself sits. I don't know, but if you look closely in that last pic I posted, you should be able to see it.

Thank you. Took me less then 5 minutes to draw it up on Adobe Illustrator.

My setup is pretty much like this... minus the trigger return.
