Warning lots of low quality webcam pictures 
Ok so you want to fill a paintball tank with air at home? Well with this you can fill your air or co2 tank to about 400 psi with a shock pump - with many pumps or to about 120 psi with a tyre pump.
Cost? About £3.50
What you need:
A tubeless tyre valve (Clamp in shrader)
A circle of rubber with a hole in the middle - i cut mine out of 3mm neoprene and it is 18mm wide
And one 1/2 BSP to 1/4 BSP reducer
Ok so first of all take your nut and washer off of the valve
Put the valve into the reducer from the 1/2" end
Place the washer on the WRONG way around
Put nut on and tighten it up
Place ruber disk in the end of the reducer
Screw onto shock pump
And your done
Here is a co2 tank at 150psi
Thanks for looking...

| How many strokes did it take to fill to 150 psi? It may be worth it to start it off with a regular bike pump up to 200 psi or so, and then go from there with the shock pump. |

Yes i think your right, dont sure how many strokes but i say it took a good 4-5 minutes  Doing it while watching tv though is no chore. |

| I would say that it took over 100 strokes if it was 4-5 minutes. Nice how to though, but how do you depress the pin valve on the co2 tank? |

| On my tank it seemed to open just by the air pressure |

| Well, looks like I found a new power source then! I wonder how long it would take to fill with a fridge compressor with no inlet pressure. |

| The only thing, is that for attaching you would have to have a way to depress the pin... either that or use a co2 tank with an on/off valve |

| Co2 remote line, has an on off valve that connects to the tank, and a slide valve at the end of the hose. And if you slowly open the valve you can semi regulate the flow. I wouldn't do that without a safety valve, but it could be possible. |

Yes that would work, but annoying NTP threads (At least for me in the uk anyway) What i would do is either remove the pin with an allen key and put a 1/2 ball valve on there and then a 1/2 inch nipple, or just get a tank with an on/off valve
