If you've already got a compressor mounted, and your a/c doesn't work, why not retrofit that one to run OBA? It doesn't have to be a york to run OBA...my friend Ryan(the guy with the cherokee in Cruces) setup his with a sanden compressor right next to his a/c compressor. The only deal with those is they don't have a crankcase like the york, so you would have to oil it every once in a while, or set up an oiler. I've seen a few sandens setup with grease fittings on them. Haven't looked into how they are doing that, but it definitely works.


Oh, and back to the subject at hand, I'm with doug. My OBA using the york and the good sized reserve tank has 120psi while idle, and while filling a tire, only drops to about 90-95 psi. I have also ran an air rachet, an impact, die grinder, and high speed sander off of it and didn't have a problem with cfm output on any of them. I like the idea of having air as long as the engine will run. :)

Herein lies MY concern. My engine spends a lot of time not running.

To tell you the truth, when wheeling my engine has always been my main concern. If your engine doesn't run like it should, normally the trip will suck, you'll slow people down, and it can be dangerous. I've always tried to have my engine working well and if it didn't, i've done my best to fix it.

What i'm trying to say is, i wouldn't wheel to much if my engine wasn't reliable. That is one thing i don't want to worry about. I want to worry about axle shafts breaking, tires exploding, etc...

fredo,
i've seen a sanden with the grease fitting. They tap into the 3/4"? flat looking bolt right on the top in the middle of the compressor.

David,
I'd also be interested in the flow rating on that reg you bought. The reason that I've always thought Powertank's were so expensive is for their ability to flow high CFM rates and maintain high pressures (up to 175psi) w/o icing. The higher the flow rate the better chance for icing. Welding regs will handle the icing issue but they won't flow enough CFM. If that thing works...that's surely the way to go.

And for the air tool questions, "How long will it run an impact?" I read on one web site that the 20 lb bottle will last for 20 minutes.

Should be easy to calculate. An impact runs at between 4-6 cfm at 90psi. I'll dig up some data on the bottles and gases....got to go find my pocket reference book....:flipoff2:

Eric just stopped by, and we tested out the regulator with his 1/2" CH impact. It didn't go so well. The regulator doesn't provide near enough CFM to turn lug nuts, but hey, it was cheap.

In summary, if all you want CO2 for is filling tires, then the $30 regulator is for you. Don't expect to run any air tools off it. Victor and Powertank offer bigger, better regulators that will run air tools with ease, but they also carry bigger price tags.

As for me, I'm going to stick with the cheap regulator for now, and I'll get my grinding, drilling, and TV watching done off of a power inverter.:D

I have pictures of the CO2 tank and bracket up on my Webshots site.

I hope those spare axle shafts aren't the sentimental ones:D ....if they are, i have a spare set you can have for $50

They are, and I might just take you up on that offer.
