lp shutter

[hexer29]

I have a shutter and you can see what i have in my sig,i polished the striker and the sear, i am not finished polishing yet though. I am currently running at about 400 psi. Is there anything else i can do to get it lower?

[ptflyer]

nope....looks good to me....mine shoots best at about 400-450psi also....I talked to terry at G3 and he said and I quote....
"First, I've never seen a Shutter that could run as low as 300 psi, the small
diameter striker makes the gun want quite a bit more pressure than a std.
Spyder....I've seen more than 100 psi variance between gauges...."
"Actually, considering the flow paths through the newer Spyders, I'm
surprised it will run at 425....most are lucky to get down to 500 psi...."

So if he says that...I am happy with the set up I have...
Plus it runs great at this pressure....consistant...and not at all a "gas hog"

[A damn fool]

actually, it is possible. My shutter runs at 280, but i run it at 300 just to make sure. Drill out ur asa adaptot, and chrom polish ur internals. My asa daptor is pretty much hollow right now, so it helps a lot. My setup is below

[hexer29]

what all should i polish? i did the sear and the striker.What did u use to chrome polish it? So u made the asa adapter hollow? I made the holes bigger. So if i drill everything out of it, that will help? Do u have pics of the asa adapter?

Hmmmmmm... I had all the LP modifications a while ago but couldn't get under 400psi. Is your shiny brass valve screw all the way into the body or flush with the body? Depending on your answer, that may solve your problem.

[hexer29]

I think it is flush with the body

[hexer29]

which springs do u use, the ones for high velocity or the ones for low velocity? i have the madman spring kit

I love youre shutter.hehe
But you diddent answer me this. You know the thing you screw the tank in to.
Where did you get that piece.?

[ptflyer]

ok......well there are two pieces to the Kapp drop zone2...one piece is the bar.....and the other is the loop at the end that clamps around my ON/OFF adapter..and the tank screws into the on/off adapter......I think you are asking about the loop part....of the dropzone2...


and thanks....

[PaintKiller]

Oh then the mirco line goes from the on/off to the reg?

[ptflyer]

yes...exactly.....

[mikek2111987]

i know that the M98 has a LP upgrade which greatly drops the PSI,so if u could find something like that for a Spyder that would work awsome,and u can go to this site http://cookie.2y.net/spyder/ and do some mods

Actually, on the Tippmann ProShop (or something like that...) advertisement, it says the LP kit will lower the pressure to anywhere from 300psi-400psi. It doesn't have a gauge, so you'll probably have to do some drilling if you got a Model 98.

Yes oh yeah oh yeah.
I Finnaly get it.

[mikek2111987]

o yeah, the reg here http://www.actionvillage.com/pmipurenregc.html
says that it can drop the PSI from 800psi to 200psi
thats what it says,im justing saying what it says

If you go from 200psi to 800psi, you're no way in hell lowering your pressure. You are, instead, doing the complete opposite. Raising the operating pressure.

[Spyder_Kid]

just cuz the reg says u can run at 200 doesnt mean you can
...a reg will not just all of a sudden make your gun lp

[A damn fool]

the reg does ntohign, it doesnt lower ur pressure, or show how much air u have in ur tank. All it does is show where ur reg is set. It is mainly a comsmetic part for ur gun, and for all the people who want to know where there shooting, it helps. As for the gold body screw, how would yhat effect the opertaing pressure of your gun? mine is screw in as far as it will go, which is inside the body of the gun.

[Hsuve]

If the brass screw is all the way into the body and not flush with the body, you're restricting unnecessary gas flow. A regulator is NOT a cosmetic upgrade, where'd you get that idea from?!

[A damn fool]

really? i didnt knwo that about the screww. Sorry, i ment the GUAGE, not the reg. thats what i ment throught that entire thread.

Use a hard Velocity spring with a light valve spring

[spacer709]

both of the springs should be light

[A damn fool]

Cans someone please xpalin thw whole spring configuration scheme to me? I wqnt to know exactly what spring will give me better veloity at thew lowest pressuree, and why? at the moment, i have the lightest springs on the velocity and valve spring. Which ones shoudl i have though?

[hexer29]

in the maddman spring kit, there is a regular size valve spring and a big one. Which one of those is lighter?

[Hsuve]

Nope, not true. If you want to lower your pressure, you'll want a stiff main spring and a soft valve spring. I explained myself in another thread, dunst feel like saying the whole darn reason again. Do a search on me, that'll give you all the posts I replied to, look for all LP posts and you'll find my reasons.

[A damn fool]

but, wouldnt the pressure need to be higher in order to push the main body spring back into place after the bll is fired, due to the tighter spring? I actualy have a thought on the subject, but i tihkn im wrong, so bear with me

If u put in a hrd valve spring and a hard body spring, woldnt ur velocity be high but the pressure low? Since the two springs would help push eachother out, minimal pressure owul be needed to push and close the valve, but less would be needed becasue the main body spring would be so tight. The onyl problem i see is that the valv emight not be open very long, and a lot of pressure would be needed to quickly fire the balL. Does ne one know if im rightor wrong? (and since im most likey worng, coud u explain which comination would be the best) I tried the light valve spring, stff boy, ad my presure was lwer with the two light prings.

[Hsuve]

No, no, no. Don't do the combination of a heavy main spring, and a heavy valve spring. You'll want the soft valve spring, heavy main spring. Here's why: If you have a light main spring, it won't slam into the valve pin very hard, thus the valve dwell time is very short. The shorter it is, the less flow. So as you can see, with a heavy main spring, you'll slam into it harder, opening the cup seal longer. That way you'll have more flow.

[A damn fool]

the onyl thing that ive heard other wise is with the heavy spring it needsmre pressure to open the valve. Know, when u meen the heavy spring, do u nmean the medium spring over the light, or the heavest spring? Oh yeah, thaks for all the help.

[Hsuve]

Nah, it doesn't have to be the heaviest spring. All I'm saying is that the combination of springs should be a soft valve spring and a heavy main spring, then adjust the pressure lower, because more than likely you'll be shooting hot.

[hewy10]

well im my shutter i put a soft valve spring and a stiff main spring and after i backed the velocity adjuster all the way out my balls were still curving and shooting way to fast so i put in a lighter one, i am thinking of cutting down my heavy spring is this ok
