This is hopefully my next project.
A 9 or 10 mm "ultimate inline"made out of galvanised steel pipe fittings, a pressure washer handle and unregulated CO2..
What do you guys think??

Besides freezing your hands off, I am sure the pressure washer handle will have seals that will freeze and crack.
Also as the CO2 is consumed, your performance will drop, as it will produce lower pressures at a cooler state. (This will also lead to an increase in CO2 consumption.)
It may be practical in short bursts.

I have never seen a pressure washer grip capable of 800 psi. Although, I suppose they make something similar that would be capable.
I agree that under full auto you will see rapid performance drop off. Short bursts might work quite well. You are going to blow through co2 though.
What are you going to be firing that are 9-10 mm, marbles? I would hardly believe paintballs would be able to withstand that kind of pressure, not to mention the spring feeding them into the vortex.
Over all, its a good looking system. I wish you luck.

Trying to figure out how to make a SCUBA first stage regulator work for portable charging station. If only that pesky job thing didn't keep eating up all my time...

Make a water jacket for the co2 tank. It takes a lot of energy to cool down a little bit of water, so it'll help keep your tank running at a constant temperature/pressure.
I'd also try this design with normal bbs. It would still pack a punch and last a lot longer.

Short bursts are fine with me.
i have a 3000 psi rated pressure washer handle, specially converted by the manufacture, to accept the fittings I wanted.
He told me liquid CO2 is peanuts for this thing.My only worry is, it's currently in use on my "overkill"cannon.
I'm not sure this thing can really be silenced, but I drew it on there, cause it won;t hurt trying, and it looks better anyway..
I plan to use steel ball bearings ( from the magnetix game/toy) wich are about that size.I will choose the barrel according to the available bb's.
(paintball?!?!? Pfff!)
BC, I won't freeze my hands off, the CO2 does not run through the grip.
I will have to insulate the bottle.( foam grip??)
As for valves freezing..if that could really occur, how would you ever turn off a CO2 bottle once it's opened??
However, I always respect your input, so I'll first try this thing without ammo..
Oh and Jack...why haven't you tried this??It's right up your alley!

Because you are using a regulated system, or valves meant for CO2, not a pressure washer handle. This seems pretty obvious.
Also keep in mind that liquid pressure behaves differently that gas pressure, and how experienced is this person with using liquid CO2? (Keep in mind that the CO2 is not staying liquid either, it will be boiling.)
My "freeze you hands off" comment was a poke at the picture depicting the co2 tank as a fore-grip.![Wink :wink:](./images/smilies/icon_e_wink.png)

I was referring to the main valve on a bottle.
Do valves on a CO2 fire extinguisher ever freeze up??
I am confident the valve will work..
How does liquid pressure behave differently??
A strafer is an open system, none of the liquid will be trapped in a confined space..It will have no trouble evaporating.
I do see a problem when the gun would be flooded with liquid CO2, but I'm pretty sure I can prevent that by using the main tank valve as a flow regulator in other words keeping it almost closed.
Nothing a little tinkering could not solve.
As Einstein once said: If at first an idea does not seem remotely proposterous, it won't be worth investigating in the end..

well..it's only 800 psi right?
I don't have any experience with sucking balls..
You tell me...
OFCOURSE IT IS!!!
40 psi is enough for a regular strafer!

Yeah..I was worried about comments like that.
NOT FOR NUBES!!
Don't try this yourself it will most likely kill you!
I mean it.
I don't mean to take away your right to ask questions, but I must discourage you to develop an interest in a system this dangerous.
This stuff is for advanced members.
The poll is a joke.
CO2 is VERY powerfull when compressed into a liquid state.
Even though I disagree with BC, I will still keep his comments in mind.( respect bro!)
Nobody has tried this so I don't really know if he's right or not. I just have a ( experience based nonetheless) gut feeling it is worth a shot.
Unfortunately I won't be able to buy parts for some time.
Maybe I'll just strip Overkill.

Well, Im somewhat involved in paintball and what you can do is rather than using CO2, Buy a carbon fiber tank. Most of the tanks are 4500 psi pressure rated and carbon fiber is very strong
. It is just filled with compressed air so it wont freeze on you or anything. Also, all of the major and professional guns use compressed air from carbon fiber tanks so i would reccomend that. If you could regulate that to 800 psi then that you be much better and safer than CO2. And just as BC Pneumatic said, as CO2 is cosumed, the performance does drop but with a carbon fiber tank, i think it doesnt until you get to last 1000 psi.
And i would feel safer with a Carbon fiber tank rather than an aluminun one, Yes they are made of aluminum, interesting. Carbon fiber is much stronger thatn Aluminum![Smile :)](./images/smilies/icon_e_smile.png)

I have a CO2 paintballtank.
If I'm gonna try this, I will use that.In bursts.
If it works out...I might get HPA.
Those set-ups are pricey, so I will first go with what I got.
Thanks for the support
