Is that your cannon? Impressive.
But I believe you are referring to the regulator thread size.
I was hoping to figure out a pipe system so that 4500psi would be realised at once, securely tied to the floor of course.

I'm guessing that even if I did use 4500psi (god forbid) with a 68ci tank, all of the air would not come out at once, it would just keep discharging for a few seconds? I am trying to figure out the maths behind it, I have done mathematical mechanics but only at basic levels; velocity, projectile mot...

I suppose... Say, how much force is required to push a man off the ground?
Heh, that would end badly.

Yup, I attempted this once before, could not get the right equipment. I made a 'bomb squad' suit out of layers of clothing and some steel sheets just incase, was all rather crude.

Hello, I am currently working on a HPA project and am having trouble finding places which sell pipes and fittings rated at 3000-4500psi. I require them to withstand the pressure for a small amount of time, not just pass straight through them. I was wondering if anyone could help me in my ordeal and ...

Sounds fun, I have been looking around but I cannot find the sufficient tubing/piping anyway :/.

I was talking about a ball bearing, By paintball in the title I meant that I was using a paintball tank not that I am actually using paintballs.

Can I ask what would happen If I were to launch something at 4500psi?

Thanks for the help!
But just out of curiosity what is the paintball tank thread size, I wanted to see if I could find another way around it, with a ball valve or something.

Hello, Out of a strange turn of events I have my hands on an unregulated paintball tank and a 3000/4500psi air compressor. I was wishing to create a 0>500(?) psi cannon out of this as I think 4500psi would be a very bad Idea (you tell me). My problem is I do not know the size of the threads on the p...
