Some things to think about.

[SunTzu]

Hey ya'll everybody enjoying their kit I am, but I still have some questions.

First off, I got the kit setup like this
preset 450psi CF
input from reg?
LPR 40 psi No evolve LPRadjuster
dwell 9
for 290 fps +/-3 fps

last weekend it ripped really hard like this but I had some FSDO probs, they went away when I lubed the lug on the valve stem end better so that wasn't a problem.
But now after only 2 cases, Im seeing wear on the valve stem o-ring.
Having read this in previous posts here and on PBN,I'm worrying that the o-rings won't hold up for more then 3 cases.
So I switched the valvestem from evolve to the original one + volumizer
and went to shoot It didnt have blowback, no shoot down and it dropped my fps a lil to 270 fps.
But it works so now I only have the hybrid hammer in my fly and the kick is gone, dunno bout efficiency.
But my question is the design of the evolve kit, no doubt the adjustable valve tension is a big plus for some of us tinkerers but this can be adjusted trough dwell also.
why would they design the stem like this, has anyone see damage on their valve o-ring?
Did anyone use just the delrin hammer?

[speedfreakspb]

We had to change 2 o rings on team guns yet.

[pblcd225]

I also had stem o-ring problems I posted my problems in the pbn thread

[SunTzu]

try the original config with just using the lighter hammer.

havent fully tested it, but check my post on PBN too
I dont wanna be changing o-rings every 2 cases or dont want my gun to go down in the middle of a game like this.
lets work this out!

[P8ntSlinger44]

I wish Evolve would address the situation at hand. The kit ahs been out for a little while now and people seam to be having the same problems. For me, I cant put my lpr any lower then 48psi or else I get horrible drop off at high ROF. And I dont feel as though I got what I paid for.

[Chris777]

We have been watching whats been going on surrounding the o ring problem and a fix is at hand. Its just a shame that the overall integrity of the kit has been damaged by one weak part.

We wanted to use an o ring type design because our testing showed that it was durable enough to last whilst being be cheaper to change, rather than having a whole new shaft and valve.

We are currently setting up a test rig with a moulded version and it may be that we go over to that, its just that the o ring idea would have been much more user friendly!

Bare with us, we are working on this.

If a fix is developed, will a replacement be provided at no charge to those who have purchased a kit already?

If a fix is developed, will a replacement be provided at no charge to those who have purchased a kit already?Here is what Chris777 said in a previous post:
...And yes, if it completely cures the fault we will be sending out replacment parts.

[o0beaner]

Ah, thanks trigga.

[anjordan77]

so have no fears they will cure the probz

[SunTzu]

great work from the guys at evolve
great customer service! :worthy:

[Scott7d]

I thought JUST the hammer in the gun woudnt work because the mass isnt enough to open the valve enough. I am curious to try it though.

[SlasherXII]

I was talking to Russ and he did say that the weight of the Evolve hammer would be a problem with opening up the valve. If they could put a little more weight on the hammer and fix the problem with the valve stem then I might consider buying a kit for myself.

[Trigga Nometry]

I thought JUST the hammer in the gun woudnt work because the mass isnt enough to open the valve enough. I am curious to try it though.I used just the hammer. It sure opens the stock valve set-up but th velocity is real low. You'd need to up the minireg pressure and also the dwell. I took it out and replaced it with the stock hammer. Got much better results.

Oh yeah, when I took out the Evolve Hammer last night to replace it with the stock one. I noticed that the metal head of the Evolve Hammer had come loose from the red plastic part (it just screws on the plastic). That too needs to be addressed by Evolve. That could cause some major problems is the metal head unscrews off and you don't know about it until you cycle the gun a couple times. I imagine that could potentially cause some damage in the gun (metal against metal).

[pblcd225]

I was also told by a source that the hammer evolve uses is not going to last(even close to the stock one) I guess we will have to see if this is a problem in the future.....

[Chris777]

Trigga. point Noted on the unscrewing of the hammer, will talk to Martin monday.

The fact is that we think we dont need to have a metal insert on the front of the hammer at all, but we need to test the durability of a totally delrin one.

When we know you will know

[SunTzu]

I've was forced to try the only hammer setup this weekend
even with low dwell, low LPR but high input I had good results, no shootdown

[Scott7d]

Sun, you went back to stock valve and stem, but used the evolve hammer?

How was the kick? This is the thing im still confused on.

Even at LPR's around 45 and 50 I am still getting "stock" kick.
Everyone else is saying their gun isnt moving at all. Mine taking single shots is ok, but rapid fire, its like im shooting a S.A.W.

When I tried the stock valve,newton LPR,and Newton hammer. I did not notice and less kick then stock.....Not sure about the rest of you.

[anjordan77]

i used not to be able to hit the broadside of a barn with my angel...now i can..i factor that as the kick being less. my teammates have shot their guns which are setup like mine was...and then mine and agree it's less kick and easier to shoot.

Agreed As long as you can keep the mod working correctly;)

[SunTzu]

The kick is a little more then with the newton valve on ( I dont use the LPR adjuster)
but my input is way too high for getting it up to 295 I think, making a reg tester so I know for sure.

I have my LPR very low 40 psi, and I did clip the spring somewhat, maybe half a circle (had some spares lying around), dwell 9.
I was experimenting with this b4 the valve came out, some people claimed to use cocker springs with diff spring strengths in the valve.
So a lil more kick, maybe the high input could cause this, but I don't really see how this can affect kick.

It's weird you have more kick, because the mass of the 10g hammer plus the acceleration. Should give less then the stock 34g.

So far I busted 2 valvestem roings from the newton kit, but I would really like it to work over a prolongued period of time.
urethane o-rings is what I need :)

cant find any :(

[Scott7d]

what is VERY strange, is dry firing the gun single shots, and even rapid fire its not bad, Especially the single shots, doesnt move hardly at all, but with paint, single shots AND rapid fire, its no different, if not actually more.

[shampton911]

I posted this in the forum about - the shreaded o-ring already but Evolve wrote me an email stating that in 3 weeks there new batch, with bugs worked out will be comming of the line, they droped the o-ring and made it a solid rubber seal so we'll se what happens.

[El Pirata]

I will keep a close eye on my o-ring and if it looks like it's going to peter out I will se about making a seal from rubber gasket material.

[SunTzu]

@ Scott7d

what settings are you using? And why do you think it's different with the paint in?

[anjordan77]

cuz the ball weigh something, so is a moving mass

[SunTzu]

havn't really paid attention to differences wiht or w/o paint have only shot it with paint.
i'll look for it next time o play
