Smile DONE: My Pneumatic Hair Triggered 'Cocker

Hey Guys.
I had some time over our long Canadian Weekend to finish off this project. Thanks to the inspiration of Kmac and Dman00 from Custom Cockers and to Mag79 for his kit: Mag79 Kit
Voila! Here is my version of the Pneumatic cocker aka pneucocker (or pneu cocker).









I've added some of couple of interesting features:
- Swing Arm version of the MSV
- Adjustable Magnetic trigger return
- Trigger stop replaces the leaf switch. Set @ ~2mm gap
- Gas through barbs @ front block
- Full sized mounting plate for ridgidy

I had a chance to test her out for the first time on the field yesterday.
All I can say is "Wow!"
I was easily keeping up with the electros on the field.
The trigger pull is as light as the original SF frame. The Magnets aren't necessary but it gives it a nice quick return.

Spyder's Fasta 18v boasts 30bps but since it is not a true force feed loader I was easily outshooting it with one finger.
As a newbie to swing frames I'm could barely walk it with any rhythm.

Who could imagine? I need a Prophecy to keep up with a mechanical cocker.

I intentionally used a Mini Rock LPR which has a larger air chamber providing me the the extra air volume.

... Hmmm... what to do next? Maybe a Slider version? :P

That is VERY clean. Love what you did with the T fitting for the line to the MSV.

Very cool. I really like how this is done. Can this be done with any swing frame?

I haven't ever owned a Trilly SF. Do they have an air assist ram in the frame, as opposed to a solenoid only setup like in a Hyperframe?

This project can only be done (easily) with the WGP SF frame.

The SF frame is uniquely designed with a Non-traditional sear and X-way plate linkage. The sear and the x-way plates are linked together such way that when the Ram hits the assembly it drops the both the sear and activates the x-way plate at same time.

A stock pneumatic Ram lives inside the frame positioned vertically so that when the MSV pressurizes it, it Fires the piston upward.

Here is a picture of the Festo Noid separated from the Ram.
The body of the Ram is made of Aluminium and the bullet-shaped piston is made from delrin.

Unlike Clippards MPA3, the stock Ram is very simple; no return spring at all. It's just the body and the piston with a single O-ring. You end up needing less energy to move the piston. An very cleaver design.

I'm going to try not to be redundant.

Since the trilly SF frame already uses a pneumatic ram to work both the sear and the X-way linkage, you replaced the electric solenoid to direct this gas flow with one of those pneumatic switches things thereby making it mechanical?

Is that right?


Regardless SWWWEEEETTTT!!!!!
