Ok, I'm building a 5 foot semi autp pneumatic cannon with a 10lb co2 tank backpack with this regulator.
http://www.grainger.com/Grainger/wwg/it ... 40&ccitem= I was wondering how fast would I be able to auto refill it with that regulator and a 3/8 diamiter hose?

Ya, so far I decided on a 6 foot long 0.5 inch diamiter marble barrel with a 4 foot long 2 inch diamiter air resevoir made out of alluminum pipe. It uses a 3/4 inch QEV and my own custom release valve and shotgun pump trigger system. It has a 10lb co2 backpack tank (thats why I needed regulator) with a 5 foot long 3/8 diamiter air hose. It also will include a semi auto bolt system with a spring and a paintball hopper sized down for marbles. It is calculated at 721fps with GGTG. I'll post pictures as soon as I begin to asseble it and order ym co2 system. And a laser sight with momentary switch on the handle
[Edit] Ohh, BTW I nkow your thinknig normal marbles wont fit in a 1/5 inch diamiter barrel, but I'm planning on using the white 1/2 inch ones used for slingshots and maybe 1/2 inch ball bearings on occasion.

I havn't found the perfect one I want for my cannon on ebay but I can get the 125 dollars for the reg from spudtech (mowin lawns LOL) and hopefully be able to order parts soon. How heavy you think it would be out of alluminum pipe?
Ohh BTW anyone live in California in the OC area that would liek to help me make a video when I'm done becasue no one around here has a camcorder ):
