Thats awesome! Its too bad you couldn't make something like this to work with a paintball tank. They're so cheap to buy and cheap to fill!
Thanks! The 5/8-18 threading on the regulator is actually the same threading used on standard paintball equipment but I don't have a cannister to test whether it'd fit. Obviously a paintball setup wouldn't fit in the back housing of the Edge which was the reason I went down this road (beyond asthetics, having this stuff hidden and inaccessible is a plus when you have kids lurking).
I like to think there is an option to reuse this in a bigger setup down the road if it comes to that, but again don't have access to a cannister to confirm it.
