Others Paradigm repair

[Woogie_man]

Ok guys.....I received my package from Tom. I was able to get a new end cap, along with one of the new plenum upgrade.

The new end cap, the rod is the extension to go to the regulator. Will get everything installed and see what happens.

I was curious if it had a rod internally to adjust the reg from the front. Cool! Looking forward to you getting it together. Oh don't forget no silicone......too soon? I need to tear mine down and do the ultimox still myself...

 

[Pumacarl]

You lucky dog! I have been looking every day for one of those plenum extenders and nobody is showing them yet. Please keep us in the loop for how how all this stuff works out.

Oh I used plenty don't worry! Lol

The system is aired up and getting ready for a test. There is a trick to installing this part. You can't fully assemble and screw everything in. If you do you will close the regulator and not be able to open it much.

I will get some pictures to show you what I mean.

Nothing out yet because I sweet talked Tom into tossing one in for me !! The thing to remember...If you are going with the external adjustment you need to pick one plenum and stay with it. Because if you change the plenum size you will need a longer or shorter shaft for the external adjuster.

Here is a picture of the adjustment location and the adjuster. Right now the reg is a little high, so I am going to shoot some to lower the cylinder pressure and then back it down. After this I will be able to snap the cap on and be good to fine tune.

Here is the back side of the adjuster nut. The scratches are from me removing it as I snapped everything together in the wrong order. There is a small access hole inside the gauge cut out that will let you pop the nut out. It is retained by a small o-ring inside the body. You will also notice the tab as well. This will stop you from really winding the nut one way or the other. You should be able to get about a full revolution of adjustment this way, and is only for fine tuning.

One thing I would change would be that little tab. Would be nice to have that not there so you can adjust from high to low and not have to worry about popping the little nut out everything. But if you have the gun set for a pellet or slug, you should be fine.

Now I get to tune the gun for some 30gr slugs and attempt to beat up on the local NRL guys.

Any questions guys, just ask!

Thanks for posting. Now at least I'm getting an idea of how the inner workings are.

 

[Woogie_man]

The inner workings are honestly quite simple, but effective

 

[CTAirgunner]

Thanks for the update man, I'm thrilled for you, keep us tuned in to how you make out.

Pro tip, I apologize if I forgot to mention in the written instructions is ....

Do not push on the adjuster wheel on completely until you have your pressure set. Push on only half way and use the hex wrench to adjust to the desired setpoint then push the wheel the rest of the way on.

 

[Woogie_man]

Yup! I did find that you are able to get three adjuster off from the back side.

It did take some time to figure out how I was going to get everything together. Lol

 

[Pnwairgunner]

How would you compare the new donnyfl to the factory moderator?

 

[Woogie_man]

To be honest the Ryu sounds a bit "pingy" if that makes sense. The factory mod doesn't have that issue. But sound wise I can't hear a difference. I like the quick removal option for transport.

 

[Bladebum]

Very cool! So it would appear we can "update" our evols to the new style cap/external adjuster without a new tube or different regulator?

 

[Woogie_man]

That would be a question for Tom, but I don't see why not. The end cap will change and then you add the adjuster.

 

[Dairyboy]

The machining on such small parts is amazing! Looks really cool and simple way to do it and like said with the end cap backwards compatible. I feel like not much adjustment is needed when I've tuned my evols. One full turn would be a huge pressure change so shouldn't need much really to make a good difference unless I'm mistaken.

 

[Woogie_man]

Agreed, you shouldn't need much adjustment. Start low and work up to a speed.

Have a buddy I shoot with that has a Corbin press and has already offered to make custom slugs for me.

From the playing around that I did on my .30 Paradigm regulator one full turn would equal 1500psi. Every hour position was 125psi. Or, if you are into measuring the regulator, if you remove it, every .001" = 50psi change. I don't know if the same holds for different calibers but this is how it worked out on mine.

That doesn't seem completely correct. It's a 32 tpi thread on the adjuster which equates to 0.0026" per hour which is about 50 psi. It's important to note that the spring stack is not linear in terms of force/deflection, it's more of a bell curve, so depending actual deflection the rate will vary. At some point I will post a a calibration in hours/psi. It can get you close; there are so many variables it is impossible to have a generic calibration that matches every regulator.

With the adjustment rod inside the air cylinder, wouldn't this lower the shot count since it would be taking up space in air cylinder? Is there a hole or holes in the adjustment rod that gets filled with air in addition to air cylinder to potentially minimize this potential negative effect? Looks like a very clever idea either way! Looking forward to your testing!
