Comp-Air Question

What does the goofy two-chambered look do for the comp-air? If i just put a male palmer stab in my ASA, would I need to move everything around or can I leave my stuff where it is and keep the thing off the goes into the tombstone?

Hmmm... that sounds confusing. Here- can I just switch out the internals, or do I need the other parts?

Yeah- do I need that low pressure chamber? I don't want my grip moved (x-chamber) and I'm putting the Palmer Stab into the ASA (once I get it). I like my stuff where it is now, and I just want the low pressure internals. I think it should work without the low pressure chamber thing, am I correct?

It's my very large gas-thru grip. And I like the way it looks. Ok, just making sure it doesn't cause the air to flow faster at lower psi (faster as in compared to tombstone) to make it work properly. I s'pose I could just try it, but i really don't want my stuff moved around, and i wouldn't want the LPK if it does move my stuff aroud to work properly.

rmorey, your both right, and wrong...    Using the Comp-Air kit on the
A-5 without the low pressure chamber is quite possible, but you will get
alot of shoot down at high rates of fire, unless you keep your operating
pressure fairly high so that the regulator can refresh the valve fast
enough.

LJ, I think that since you have an x-chamber after your stab, the x-
chamber MAY slow down the air flow even more, creating more shoot
down. But like I said, if your keeping your operating pressure fairly high,
you may be able to avoid shoot down.

I'm no scientist so I'm not gonna pop off some numbers to prove what I'm
saying...   I do however know that some people have used the lpk w/o the
low pressure chamber, they have their regulator going straight into the
tombstone.

Thats what I was worried about, shoot down (couldn't get the right words out). Since that little thing provides volume, wouldn't my expansion chamber provide volume? My x-chamber is quite a bit larger, and from what I see on the LPK is a reg and a chamber (standard setup). If my reg is in the ASA, and I've got a large chamber attached to the tombstone, wouldn't that do the same job?

I dont see why it would work.. still...

That palmer should do most of the work, and the expansion, shoulda harm or cause shot down...

Honestly, just give it a try.. I doubt you would experience any problems.. if so.. somethings gotta go.. though it seems thats not something you want to do.

I belive what you're trying to say is that the regulator lets out a burst of gas until it receives back pressure of the given psi. After connecting the air source, the air should fill all chambers. Upon firing, the lowered psi input will cause the air to enter the CVX slower. It should work much like a single file line, as the air moves during rapid fire, the regulator should be constantly pushing air out to reach the correct pressure setting. I am using an 800 psi output tank, so this should give the regulator plenty of push against any movement of air. If the input pressure into the gun is 400 psi, then the regulator should be able to easily keep up with an 800 psi input into it. It's kinda like a shower with an open drain being filled with a fire hose- even though the drain is draining water, the rate of drainage is lower than the rate of filling. I just wanted to check against any who may have had experience with this.

For some reason, it seems I'm the only looney that wants to keep my x-chamber on a HPA based gun. I like how close it's positioned to me, I like how its shaped for my hand, and I like how it looks. On ocassion, I have to hold my gun like a LAW or RPG to shoot in certain situations. Ex- I'm pinned down, but I have a shot on someone on higher ground, and I'm pinned on the lower ground. I'm able to hold my gun like an RPG & lay back and fire at the high ground, while staying covered from the attackers on the low ground. It's a weird sitaution, but my local field has an area like that. It's great fun to surprise the bejeesus outta the fellows on the high ground.

I've been told a hundred times that I don't need the x-chamber for HPA/N2. But, I do need it for a grip/looks. I like it, and it can help act as a volumizer for the LPK. The reg on the tank is good enough for ormal operation, but now I need a reg only to control the psi to lower it for the LPK.

Regulators don't work that way. The regulator isn't open until it detects
back pressure. If you could actually slow down and see what's happening
in the fraction of a second that the regulator is actually allowing air to
pass through it, you will have a "high pressure zone" and a "low pressure
zone". The area right after the reg, in your case your ASA, will be at a
much higher pressure than the area of the valve. Hence, the regulator
will cease to allow air in, until the air in the ASA has moved ALL THE WAY
to the valve and a stable pressure has been achieved. Obviously now that
the air has spread out to fill everything from the reg to the valve, the
pressure will have lowered. It is now that the reg will open a second time
inorder to allow a very small amount of air through to reach the desired
operating pressure.

This all happens in fractions of a second, and the time it takes the air to
move from the reg to the valve will greatly affect the time this takes to
happen. When running high pressure the air will travel much faster than
when operating at a lower pressure.

How does the low pressure chamber come into play? I can't honestly tell
you because I don't have any experience them. But this concept of high
and low pressure zones and the reg opening twice, IS how regs operate
on a normal high pressure gun.

If I were you and I didn't want to have the vertical adapter and low
pressure chamber on my gun... I would remove the x-chamber, and place
your reg into the tombstone, as close as possible to the valve. You can
then use your reg as a handle instead of the x-chamber. Got a guage on
it?? Set your reg and then take it off!

BTW... still looking for that animation that shows how a regulator
works....

Ah, an update-

I have determined what I need to do to make this work. Unfortunately, my particular x-chamber has a very small hole on the top to release the air. I removed the chambers, and all I had to do was drill open the mouth of the x-chamber. UNTIL, I realized the bottom portion of the x-chamber was held on by a bolt that connected from the top, and was threaded all the way down to the bottom. If I don't drill out the mouth, the low pressure air is too restricted and can't get into the gun fast enough. The recharge rate is fine/ will be fine, since the volume of the x-chamber is similar to the volumizer's. Here's my dilemma-

Should I

1) Attach the bottom portion of the x-chamber with just red loctite.

2) Drill small holes and use small bolts to hold bottom portion on.

3) Do both.

Or do I have any other options? The portion I need to attach isn't very long and contains an o-ring around it. Only problem is that after its attached the bottom won't spin to allow me to re-position it. I'll just have to make sure the tombstone will fit on correctly before attaching it.

*edit*
Due to time constraints, I went with choice #1. Please tell me if I made a bad choice.
