DONE: My Pneumatic Hair Triggered 'Cocker
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. Kits can now be had by MCBer here Pneumag Kits
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
post a video please?
also what is actuating the 4 way?
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?
I want to do this now hahah!
That is very cool. I want a video for sure. I have been trying to figure out a way to do this, but never thought to look at the SF frame, kudos to you.
