    Other than the price it looks awesome. Have heard about this being done, probably can get a CO2 welding tank and add a regulator and accomplish the same thing cheaper.

    I remember a while back, I called a few welding shops about setting up a the same thing and it was about $100 to $150. So it might be worth looking into.

    I read about that after I made this post. A few people on the pirate board have done it for anywhere from $100 to $190. I'll definitly have to look into doing it that way. I'm still wondering if anyone has used CO2 to air up their tires, and what they think of it.

    I use a 20lb co2 tank to air up my tires. It's the best thing going. If your buddy needs air or you need to run air tools-you've got it. I run 44's and 1 full tank allows me to air back up some 25-30 times before refilling. One caution,when co2 cools down after driving-psi drops

    How much does the psi drop? What regulator and hose are you using? Thanks man.

    I've been using a power tank for about a year and have gotten pretty fond of it. I have the ARB compressor, and can use it if I run out of co2, but haven't had to yet. I have the 10 lb bottle and it does my 37's several times before I have to think about filling it. Plus we have a system to fill it out of our welding bottle so it doesn't have to go to the welding shop to be filled, that helps.
    The portability is a big part of it. I've taken a couple of trips in vehicles other than my K5 and we just toss the bottle in and go. It's been to wrecking yards, done stuff around the house and around our shop where a hose won't reach. It's also nice for working on other vehicles on the trail when they're more than a hose reach away.
    A small compressor and a tank will do ok for filling smaller tires, and will run tools pretty well, but the power tank works more like an engine driven compressor without having to mount the compressor. The best place to mount one is taken up by my hyd. pump, so it's REALLY handy to have the tank.

    I looked into doing a bottle from a welding shop, but for two stage regulator (maybe not necessary, I haven't played with it much) like the power tank uses, it put the cost of the system in the same ball park. I just bought the tank and bracket and called it good. I figured for the $50 for the mounting, I could screw around at least a full day trying to build my own.

    About the only situation that I've found CO2 doesn't work well in is continuous high output applications. The co2 needs to vaporize in the tank to create pressure and running an air chisel or something like that that takes a lot of air will suck off the vapor and then you'll have to wait a few seconds for it to heat up and revaporize. It also drops tank pressure in cold weather, but I haven't seen it below about 500 psi.
    As for tools and tires, they don't mind a bit. I'd have to look at it more closely to be really scientific about it, but it's thermal expansion rate is similar to air so your pressure change with temperature should also be similar to air. You'll have to adjust your pressure when it gets really cold to keep it just right. Or put a couple more pounds in to keep the beads seated as tires cool off on the trail.
    Hope this helps, feel like I've written a book here!

    If you go to National Welders Supply before the end of Feburary, they have tanks on sale. Plus you have to get a Oxy. regulator and they switch out the fitting so it will fit on the Oxy tank. Depending on the size of the tank you get cost is about $130. I'm considering either that or a York setup. I'm starting to lean towards the CO2 system again. I don't want to try and figure out how to get that crap under the hood. With all the Emission equipment and misc. stock stuff, its pretty cramped under there.

    I'm using "Power Tank's" regulator-just bought a larger tank from local shop. On the psi issue, say I aired back up and it was 60 , if the temp. drops to say 30 at nite-the next a.m.-my tires would be about 10 psi lower than when I went to bed. My tires hold more voluum air than others and I'm told it's not as much of a problem on smaller sizes
