Mag Mod Idea

[Mad_Man]

Alright, I have an idea for modifying an automag classic valve to be run by a pneumatic minivalve and regulator to change the velocity. I would drill out the back of the valve until the threads are gone from where the regulator nut screws in. I would put a small ram with a point on it to hit the poppet valve already in the classic valve. There would be a spring on the front of the ram to return it. Behind the ram, the back of the valve would be closed off with a gasketed-plate, and the oil holes tapped and bolted to seal. The minivalve would be supplied by a LPR and controlled by some board such as a morlock or otherwise. From the minivalve (similar to the one used in 'The Electrician's' emag mod) the LPR hose would go to the back of the valve to power the ram forward to hit the poppet valve. As I said, a regulator would control the velocity, and there would also be no need for the sear, and the on/off bottom could be tapped and bolted, but left in place to seal that hole.

Any opions or criticisms? Just an idea i figured that i would float out.
Thanks

Umm... The "poppet valve" is the regulator pin and seat, right?

Seems that to make the whole thing work well, you'd also need to have the dump chamber filled in.

I suppose the idea could float. But why? What would the advantage be? How would the consistency be affected, and how much would need to be modified to allow for sufficient air flow through the poppet valve to propel the paintball?

Would probably be a lot less work taking a current poppet valve design and simply converting it to a power tube and bolt lifted from a Mag.

[Mad_Man]

Yeah, the poppet valve is the reg pin and seat that are already in there.

Well the benefit would be it being controlled by an solenoid valve and board, thus being an emag. I would assume the valve are would have enough flow as it is, because it has to refill the dump chamber as the gun fires as it is.

If you have an ideas for non-spool valve singletube designs, i would like to hear them, but this is the only one ive though of using the valve for ease or making it.

Also, with a morlock, the dwell could be changed to controll the volume or air and the pressure from a reg. to help tune efficiency. I dont know wether this would be efficient or not.

Thanks for replying.

You suggest in this mod that you'd eliminate the sear, but the sear is also retaining the bolt in the standard mag design, not just triggering the on/off. Would the bolt spring alone be enough to reliably keep the bolt held back to load a ball? How would this affect level 10?

[SlartyBartFast]

Firstly, I doubt that solenoid control is accurate enough to result in good consistent control of velocity. I know other E-markers use dwell settings for this purpose, but all I can think is: "Great, another cheater gun."

I highly doubt that the current reg pin would allow for sufficient flow to directly fire the bolt and ball. Currently the bolt cycles in about 5ms consistently. the limit to CPS is the charge rate, with is much higher than 5ms.

Also, I can't see this mod as being anything but a hit to efficiency/shots per tank. As the general firing oepration/bolt is identical, that won't change efficiency. But, you'd be adding a ram that would be consuming air. That would lower efficiency compared to the current setup.

Well, are there other designs for a single tube gun that doesnt use a spool valve, and uses the mag power tube? Im open to ideas, just looking for an electronic alternative to sear-tripping.

Whats a spool valve exactly>?

[Mad_Man]

Its kind of a bolt and ram in one. Air from a minivalve pushes the bolt assembly forward and before the bolt makes it to the end, the dump chamber is sealed and then emptied by the forward motion of the assembly. Then the minivalve reverses and pulls the bolt back.

The DM4, Matrix, and the 03 Shocker are just some I know of.

im not sure why its such a big deal where you adjust the velocity from, sounds like a waste time to me but thats just me

The "Big Deal" is actually easy to understand. Velocity should only be adjustable by mechanical means.

If it can be adjusted electronically, you're opening the door to simple cheating and on-field adjustment.

Yes, It's hard enough as it is to keep people from upping there velocity on the field, especially at Scenario Games...

^Theres two more reasons why its a waste of time, in my opinion.
