While browsing my local Craigslist for a new lawn mower I stumbled on an add for a garagesale. There was only one word in the listing that caught my interest... Co2. Thats it, thats all is said abhout it and there was no number or contact info. Seeing as im the kind of guy who would rather do something then afterwards realize it was a waste then not go and just wonder I hopped in the Cobra and headed off. Mind you this was about a 55 mile round trip. When I pulled up to the small home there were many things strewn about in no particular order Except a collection of aluminum and steel gas tanks.

Here is what I scored!!!

Here is the old school regulator that is on the large tank.

Check out this beauty!

And the perfect tank for my nano at work!!!

Check out this regulator. As you can see there has been gas in it for who knows how long. I have never had a pressureized tank set up but is it normal to twist the release valve on the regulator to the righ to let the air out and to the left to turn it off?

I know they are these tanks havent been tested since abouththe time I was born! I got ahold of Airgas here in stl and its $30 to hydrotest and $24.71 to fill them up.

I know hydro testing for small tanks is around $20, that's IF your tanks are outa-date.

Actually the one that was reading on the regulator still had come co2 in it. I emptied it and there both at 0.

Got it all for $25!

It looks like the regulator with the two gages has been set at some outlet pressure for a long time, with the outlet plugged, and it leaked through the regulator just enough to overpressurize the outlet pressure gage. The gage may still go back to zero when the presssure is relieved.

Relieve it by unscrewing the adjustment handle on the regulator - turn it counterclockwise, until it feels loose. Then crack open the fitting that must be sealing the outlet. Or, shutoff the valve on the CO2 tank, and loosen that fitting to bleed off the trapped gas.

You got a great buy there if you paid $50 or so. Maybe even more.

That would be for a swap.

That seems expensive. I use Airgas here and it only costs me $19.00 to swap for an already filled tank. Maybe they'd let you just swap the tank for less?
