Pnue cocker

[Toll]

Does anyone happen to know where to get something like the msv1 in a 4 way?

I was looking at cockers and I figured it'd be a neat little project to try to modify them in the same way as a pnue mag...Lose the frontblock entirely, mount the ram to the body and voila, a very weird looking and satisfying autococker. No short stroking, no crap like that and just as fast as a pnue mag.


The lynch pin is ofcourse the cocker 3way..which happens to be a 4 way. Msv1's obviously wont work due to the fact that I have a loose hose on the ram


Ideas?

Wel,l you could always use the valve actuated by the trigger to actuate the ram's "three way". But one valve actuating another might not work so good.

You could also consider hooking it up to be open bolt, yb reversing the three-way and adjusting the timing. it might work better if both the firing and bolt movement are in sync.

Making an electro sear-tripping cocker with a valve actated sear would be petty uinque. Low power consumption and all that.

get a spring return ram and plug the port?

I would love to see a cocker timed for open bolt. Is there anything that suffers in an openbolt cocker?
(other than the accuracy gained from a closed bolt marker) :superdodgy:

I don't know much about autocockers, but isn't that pretty much what an eblade is?

[the electrician]

no, read it carefully. he said a valve actuated sear. in otherwords, a valve runs a tiny ram that actuates the sear.

an eblade of course uses direct solenoid actuation of the sear. the first electro gun I made was a direct solenoid actuated sear, but in a different manner than the eblade works.

I am actually going to be converting a sandridge cocker into a version of a solenoid valve controlled sear. basically using the same setup as my electro mag, only a pull type cylinder and turned to pull the sear down.

a little more complicated than my direct soloenoid design, but lower power consumption than mine or the sandridge, and it will eliminate all that extra muck on the front and the big plastic box under the grip.

it could be done using mechanical valves, but the trigger won't feel that much different from what is already possible with a hinge frame and a palmer quick switch.

The best thing I can come up with is to lose the hammer entirely and replace it with a spring return ram with a qev. Then cut a slot into the side of the body for a connector rod between the piston and your 3 way (4 way). So, when you actuate the ram via 2 way or w/e it fires forward, engaging your main valve, almost immediately vents and returns. Simultaneously, it actuates the 4 way to load another ball. This is where the problem comes in, it would be terribly difficult to set it up such that the bolt remained immobile during the firing sequence. Unless you set up some sort of slider setup, and that would be difficult to make work.

Then theres the whole thing of it more than likely looking gross.

You can't do that mechanically like your thinking. How would you control the dwell with a triggerd valve that runs the ram? You couldn't without intricate precise subminature flow controls. The poppet only needs opened for a specified time, otherwise the efficiency and consistency will suck tremendously.

Now you could use a solenoid valve and a ram to control the dwell, but then you'll still be electro and you might as well have bought an MQ-Valve (which is basically just a strong noid punching the pilot on the valve directly instead of a hammer or ram)

The DW Aedes actually does something like this as well. The Big Solenoid punches the piloted poppet valve and air drives the bolt forward while propelling hte ball. The bolt is simply just spring return instead of ram return. Super simple means super fast as well as super reliable. This is the reason Nicad referred to a full mech version of the aedes possibly in the future. He'll simply use a dwell controlled pneumatic frame to drive a ram into the pilot.

If you want to figure what's needed for a dwell contolled mechanical valve-ram setup... I suggest PMing Nicad or RRfireblade.

Like an emag?

Like an emag?

I'm guessing that when he says "solenoid vavle controlled sear" he means that a solenoid vavle controlls a cylinder that controls the sear.

Dwell control

What if you used say a clippard MAV-3? It seems like it would bleed at the end of trigger stroke, so the qev would blow off, enabling the actuator to return, and keeping dwell to a minimum. Then, it would be possible to adjust dwell with pressure and spring tension.
These are my thoughts, if they dont make sense, do tell, as Id like to do a mod like this on my beater cocker paralleling the pneumag mod I plan on doing.

That doesn't make sense. The peroblem is not getting a short dwell. It's getting a dwell that is consistent to <1ms

The only way your going to use off the shelf parts and control the dwell is a Solenoid valve driving the Piston. Otherwise, your goin to have to have flow controls made for this application.

Alright thanks.
