120 psi is good, I would say you can start now.
Paintball tank set up isn´t too expensive, I´m pretty sure you can get a tank+reg+remote for around 60 dollars, if regulated down to 120 psi, it can dure a 1000 shots I think. You need a place to charge it through.
If you are going to charge it from your compressor, a 8 or 12 onze co2 tank+pin valve+remote will cost around 40 dollars, it would dure around 10 shots (if you charge it with co2, you will need a regulator again, but also far more shots). Not a economic option , but looks more profissional.
The cheapest way would be make a large pvc chamber or use two 2L coke bottle, they will be fine at 120 psi and will give you more shots than a co2 tank at same pressure. |

Thank you! thats all i need to know, right now. i think i gone do the large pvc chamber, there are enough plans for that around the web and its much cheaper than a co2 tank, and since i dont have a place to charge, i will pretty much trow a way money  maybe on a later stage i buy a tank with reg and remote and get it filled in a scuba shop, but i dont know. i like the idea of havving everthing at home or just very common.
But thanks again for your help i now gone make that pvc chamber and the chamber for under the gun Thank you very much at the ground of my heart! |

cause your instuctions arent correct i think... does it even mather wich diameter pipe you buy or can i just take any kind of pipe that fits with a reducer and n cap. than if so whats the formule for the volume of the chamber, so i can make it correct with the 10 cm rule you gave me....
sorry a little upsad the stores close at 6 and i had to work to 6 so i have to wait the weekend now  |

What´s the size of your QEV? The one I used in the video is 1/4.
Cylinder volume= base area*length. I was refer to a 1/2 dimeter pipe, so 10cm length would be around 20ml.

its defintly 1/2 (http://www.spudfiles.com/forums/files/qevebay_110.jpg) threads for the qev, maybe you got some kind of other qev ?
but i get is the pipe should be 1/2 inc 10 cm long with N cap, the reducer is for the inlet(if needed at all) |

So it´s just 10cm of 1/2 pipe then
Is your slide valve 1/2 as well? If it isn´t, you will need a reducer to connect it to the QEV. |
