Re: A bit of Nerf fun
300fps is at the upper end of hardcore nerf performance. That's awesome.

Re: tennis ball gun for my dog
Come on man. That's not what he meant and you know it. He said "tennis ball gun for my dog", so clearly what he's looking for is a gun made out of tennis balls that he will launch his dog from.

Re: Designing a inline piston pressure regulator - Fluid statics math model
You can use X-shaped o-rings to reduce friction. I use them on my piston with standard o-ring compression and I can easily move the piston by pushing it with one finger.

Re: Designing a inline piston pressure regulator - Fluid statics math model
Personally, I have only made hybrid cannons and I never had to understand how a pressure regulator works, so I don't know how a pressure regulator works. The ignorance isn't by accident. When I can, I let the rest of the world do the thinking and heavy lifting for me. The pistons in a hybrid are ver...

That's a lot of work to go over. Not sure you'll get many bites to be honest.

Re: Air Cannon Design Help
Download GGDT (gas gun design tool) and use it to model the cannon's performance. Look around in the pneumatic cannon section for design ideas. I'd imagine a piston cannon would be a good choice. Air is thick and soupy, so a large enough piston is needed to avoid choking the thing off, maybe around ...

Re: Source for Thin wall 1.5" pipe
I use 1 1/2" SCH10 aluminum pipe for golf balls. It's basically perfect.

Re: Does Ice Bullets Actually Work?
I'll give it a google to find out. I think you'd have to try it out yourself. Also, if you were going to use them you'd have to carry around a freezer with you, right? Remove bullet from freezer, quickly load and FIRE! I think it would just shatter into dust and water vapor if shot from a real gun, ...
