Paint Ball High Pressure Filling Kit

The secret of the non liquid venting, even with the bottle nose down sits in the collector.
If you remove the current nut as part of the collector, the use of the 20 oz bottle will be disappointing, as you will vent about half of the gas in the form of a BIG white cloud in the first 2 flips.

The H II system is just the best I could do inside the weight and size, and not ment to be upgraded without replacing serious parts.

An option is to block off the inlet, and put a paintball hose and push locks between bottle and collector. This means youll need a bottleholder. (again a few grams)

Thanks for the info Mario, there is no chance of me taking apart any of your good work.All I am looking at doing is trying to fit a bigger bottle by fixing a new bottle holder and then joining it via a short length of pipe to your original bottle connector.So in theory everything is the same.So all I am looking for is a short length of pipe with a male thread on one end to screw into your collector and a female thread on the other which will attach to the new paint bottle.Sounds easy to me....but there again, what do I know ?

Actualy there are more solutions and upgrades possible, if you have the machines available.

More options I see atm:

The buffertank is also a 12 oz bottle, but with another kind of direct connection.

So, by making a second direct screw in connector with liquid stopper and fitting it on the existing buffertank inlet, you carry 2 12oz bottles. But then youll have to move the buffertank, and that can be done with an hydraulic 3/8 bsp hose.

Other thing you can think about, now the 13.6 kg limit is there. The 12 oz buffer has only 2.2 times the volume of the ram. Normaly I advocate 3 times as a minimum. So, a 20 oz buffertank would increase the speed of the flips too.

Best option according to me, is to replace the collector with a wider version, were you fit a 20 oz bottle and 20 oz buffer.

Morning Mario,
Thanks for your advice.I think for me the top priority is more flips,Although as it is now there is nothing wrong with the amount of flips if my driving skills improve:)
The speed of the flip and power of the flip are fantastic!... So why am i thinking of changing things?..... I guess you know the answer to that one.
I like the idea of two 12oz bottles,keeps the bot the same width.What would the effect be of not having a buffer tank?and just two bottles,in my simple mind i have two bottles now,so the flow should be the same or is the hole size on the buffer larger.
Looking at the weight of a full 12oz bottle say 1kg and the weight of a 20oz bottle say 1.6kg.. if I have two 12oz bottles and a buffer will the weight be higher than a 20oz bottle and a 20oz buffer.I think i will get a bit more co2 in the 2x12oz combination and technicaly for me a simpler modification.
My choice would be a new 20oz bottle keeping the existing 12oz buffer as im happy with the speed of the flip and it would save a little weight.

The only reason your robot has such powerfull and fast flips is the buffertank. If you take that out, you will not have sufficient gas to flow to your cilinder and therefore loose momentum. A paintball bottle only has a very small hole where the gas comes out of, the buffertank is needed to supply the cilinder with sufficient readily availabe gas.

2 paintball bottles will not improve it. 2 paintball bottles AND the 12oz buffertank will give you you increase in flips and maintain the same power and speed. But you might also consider dosing the flips, only opening the valve for half a second and make it close automaticaly. that way you also save on gas.

Morning Leo,
The buffer tank is here to stay!
Silly question but is there no way of making the co2 hole bigger?.. you know like changing the valve.I know the burst disk is a part of the valve,so i guess its not possible.
i already have a timer circuit set at 1 second works well and a dc-dc converter to fire the valve at 36 volts,as you recomended.

The paintballvalve cannot be altered in a dependable or safe fashion.

And the timer is a bit long if you ask me. .5 sec sounds more like it.

I wanted a quicker one,but thats what i got for under £10 from maplin.
I think a diferent variable resister will give me a quicker time.at the moment it ranges between 1 sec and 60 sec.Thats something i can do:)
Another question!
If i where to buy a short flexible hose,what pressure will it need to work to..70 bar/1000 psi,and what is the type and size of thread on a paint ball bottle?
Thanks again Mario/Leo

Paintball shops sell a 1/4 outer diameter hose with fitting push locks. Those have a 1/8 NPT foot.
And yes, that material has the official rating for CO2 use.

Thanks Mario,
I will have a look!
