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

:rofl: :rofl: :rofl:

very nice... and thank you...

ugh, just looked at the pictures again. do you realize that you have a lot more hose in between the MSV-2 and MPA-3 than necessary, and if you cut out the QEV and extra hose, it might actually increase the max ROF?

From what I understand, max ROF won't be all that significantly affected. Also, from a technical standpoint, Pneumagger felt that a QEV was the best route to go, and I trust him with that.

I know there is a lil extra hose but...who sees it anyway? Doesn't really get in the way of anything so no big deal.

Oh yeah, still workin on getting the vids, but peaking at around 19-20 bps w/ this emag on/off, I don't think ROF is a limiting factor...

Slade is technically right...It is not necessary. But whenever I've run a ULT, Classic valve, or any other not so reactive setup...I tend to get chuffing and shortstroking past about 12-13 BPS with no QEV. Plus, because of the distance to be traveled from the MPA-3 to the small exhaust ports of the MSV-2, I felt that a QEV was in order. Feel free to remove it...It will still fire faster than humanly possible with a well set up ULT.

So who can help me with a similar mod. My rig can be viewed here I'm obviously willing to pay for this and I would want it prior to Shatner 06.

Got you covered ike a Jimmy-Hat. Drop me a PM.

although its dead sexy in black, anno it green so you can call it the "Pea Mag"

:rofl:

its not a matter of who sees the extra hose, its that the air has to move through the hose. you have a huge loop of hose there that the air must flow through to get to the actuator. also the QEV is placed in the middle of the hose, not on the actuator itself, so to vent the air still has to flow back through the hose, which defeats the purpose of the QEV... the only way it can help is by allowing some of the air to vent through the QEV instead of through the MSV-2, since the MSV-2 has a fairly small exhaust port, but then again, it also has a fairly small out port, which the air has to flow through to go through all that hose.

if i owned the gun id cut another length of hose (as short as you can) to go in between the actuator and 3-way, and test the marker. then you can decide whether you want to go with the QEV or not, testing the two would be the best way to decide.

That is the only problem I've found with the MSV-2 at this point. The fact that the hoses go in/out of the bottom mean you gotta loop the hose all the way around. I've been trying to order some MSV-2R valves, but they never seem to have those. Those ones have the hoses coming out of the top of the 3way. I've put some serious thought into modifying the MSV-2 to have the output come out of the top and have a slightly larger radius at the ports and exhausts for better flow.

I'll have to ge around to posting my MPA-3/QEV combination. Keeps the QEV attached to the MPA-3 while still having a low enough profile to not have to chop the frame up at all. The MPA-3 isn't even drilled for a new input. I think that it would even please slade.

it wouldnt be too hard to drill out the MSV-2 to have new input and output ports, and simply plug up the other ports. you could also try flipping the lever, although im not sure what that would entail.

IIRC there are actually 3 exhaust ports, so that the valve will have a quick enough exhaust without having the ports too large. they probably designed the MSV-2 that way because having an exhaust port thats too large could cause problems, so be careful if you try to bore it out.

how did you manage to attach the QEV to the MPA-3 without drilling a new input or chopping up the frame? given you probably have an RPG frame and i have a logic frame, but there cant be THAT much more room in the RPG. I managed to fit a QEV on the MPA-3 in my frame, but i had to mill the frame (for both the MPA-3 and the QEV), drill and tap a new input on the MPA-3, and cut the MSV-1.

that reminds me, what is the ID of the RPG frame? i had to mill out my logic frame and file down the MPA-3 because the ID the frame was milled out to is actually the bore size of the MPA-3.

I flipped the lever on one...but tried to do so with a dremmel and hand drill...it kinda worked... but failure eventually won the day.

I have a logic frame too. All i did was widen it to fit the MPA-3. other than that there is no extra milling for the QEV. This means that i can take out the pneumatics to run normal mech if needed. I'll post pics when it gets back from Slipoftheknife Anodizing Co. my whole mag is getting a blue acid wash as we speak.

/thread hijack

So how 'bout Shorty's Mag?

[>><<]

You guys are confusin me with all this technical stuff! hahah

Mag Looks great if i wasn't broke i'd prolly have to get this done.

ooh, yeah, a dremel and hand drill doesnt sound like the best option.

oh, okay. i can still convert my frame back to mech too without much of a problem... not that id want to.

i dont see any technical stuff, do you, pneumagger?

[cpt]

My goodness, that's beautiful!!!!!! I there anywhere with instructions how to make something like this?

yeah, everywhere you turn on this forum.

try checking the workshop.

[shorty24]

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.

I'm eager to see what Pneumagger's setup looks like, too...
