View Full Version : Newton LPR brass Cone & Spring

I just noticed something about my Newton Evolve LPR Cone and Spring. If I sit the spring on the Cone portion that presses against the LPR's piston, it is not centered. It is way off. This would mean that my spring and/or cone would not sit properly in the LPR piston and housing. As someone suggested earlier, my spring is not even close to being square! I wonder if that could be causing my Newton LPR problems?

I am trying to get a hold of a digital camera to take a pic. If it is possible, can someone take a look at theirs and let me know if the shaft part of the cone piece (the part that goes into the spring) is centered. Post a pic if you can. I will post a pic as soon as I get a hold of a camera.

Thanks!

Here are some pics I just took. How does it compares to your Newton LPR parts that are working properly?

That's a poorly designed/manufactured spring. If that was made from quality 'spring steel' you wouldn't see those gouges in the end coil. Spring Steel is quite hard and that spring looks very soft.

Chances are Evolve didn't 'make' them though, but I would suggest they go to their supplier and gripe about the poor QC going on.

I haven't installed my kit yet, but I just looked at my spring and it looks the exact same!

peegee is saying that the spring should center itself under pressure.

I am not concerned with the rough edges on the top and bottom of the spring, I am concerned about how it is not square, as Raoul pointed out to me a while ago.

When you stand the spring on a flat surface, it looks like the Leaning Tower of Pisa. It leans to one side. I suspect that it the cone is getting hung up on the other part that is in the cap. Why else could I not get my LPR below 65psi no matter how far I screw the adjuster screw in. I preset my LPR to 100 psi before I put the cap on. It I cannot bring it below 65psi, something must be wrong.

If when you screw the adjuster screw in, it compressed the spring and therefore the pressure should change. It does not.

lately i've been just using the internal LPR and the Valve. I don't have enough shims to boost the internal LPR up to 100. So far its been working out great. I have my internal LPR set to 50psi.

So I guess are their any advantages to the Adjustable other than the fact that its adjustable? Could it be fine just how it is?

The new LPR Cap is only to make it adjustable. It is really for those that like to tinker and change settings to tweak their set-ups.

At this point, I demand that the Newton LPR Cap work since I paid for it :evilgrin: .

Don't get me wrong, I love to tinker and I love to tweak... But I don't love putting something on my gun that doesn't work the way its supposed to while the stock part works just fine. :-D Maybe its just me! :lightbulb

Here is a better view of what I am trying to describe with the spring.

I do not believe that a spring that has that much off-set, can still center itself in the LPR cap and not alter it's function.

Its quite funny to see how messed up the spring is(dont take it personal TR) I must give you mad props for sticking with the mod and trying to fix it, I gave up a week ago(if it cost 160+ you should not have to spend as much time as we have trying to get it to work) Hopefully we will find a fix soon, Its sad to tell ya the truth :notsure:

Oh, I'm not taking it personally because I didn't make or design the kit ;) . It's just bugging me why the LPR isn't working for me. Now I just have an unhealthy fixation on wondering why the kit is having problems. I guess I'm just trying to trouble shoot what could be wrong. Heck - I could be wrong on all my assumptions.

Regardless, I have the kit un-installed, got me new WDP volumizer and gauge on and I'm rocking.

Same here and zero problem this past weekend;) Other than the fact my valve stem has a small leak in it from changing it the 5million times when I was working on the kit and changing back to stock ;) But its a cheap fix

i got everything working ok @ 45psi, but fell victim to a broken valve oring. good thing they included a couple extras.

Still using everything stock on the LPR side, but was running 60psi. Took out one shim and it was at 45psi with FSDO, put dwell to 10 and it cured most of it. Ill see how this goes for a while, and if it doesnt go well ill put that shim back in.

After this weekend I am going to try to set things back up with the cap. Ill post how things go when I do this.

I'm not one to dismiss anyone's problems but I've used tons of springs like that in paintball applications without problems. While the spring not being flat, or square as you call it, is a definate QC fault it is unlikely that it is the cause of any irregularities in consistancy. If you want to put my thoughts to the test hit your local hardware store and look for a spring that's about that same size. Maybe a little longer but if at all possible no bigger or smaller in diameter and try it with your evolve.
