    i am in the process of fabbing up some tube bumpers, and wanted to know if anybody has some good ideas on the best way to make them into air tanks. i am also considering converting my a/c compressor to be used to kep them full. any ideas????

    thanks rob

    1 trip to Tellico and your ass has gone crazy. Sounds like you have been working non stop since you went home. post some pictures!!

    Using the bumpers as air tanks is something I really don't advocate, after having seen pictures of one that failed. If you really want to do it, make sure you use only perfect materials. I'd also find an experienced piepfitter/boilermaker with a TIG to seal it all up.

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    keith-and you havent??? lol talking about 38's one saturday, rolling on 38's the next!!!

    i have done a lot of work, but most of it is just stuff i couldnt do while i was in germany. i did the "rockerknocker" up grade last weekend. and it was a PIA, i can jack the whole side of the truck with my hi-lift though!!
    i also fixed my shock mounts, but the angle iron i used for the top mount is just a mock up, and needs to be finished with thicker metal, and needs to be dropped about another inch. now i only have to worry about dragging the diff, and not the diff and 2 shock mounts!

    right now shes in the shop getting the cage put in, but ill have er back this weekend. i am really ready to go wheeling again. what do you georgia boys have planned??

    later rob

    AIRBORNE!!

    I plan on going back to Tellico in August after our club ride in Alabama. Those guys tend to break stuff everytime so it might get pretty mean over there. We are going with the guys from XTV. They were featured on rockcrawler with a tube frame thing called the Raptor. http://www.keith.rockcrawler.com

    i'm turning my nerf bars into storage tanks as we speak. i had the guys in the weld shop throw some plate on the ends, and we're welding in a steel schraeder valve today.
    one of our vendors is kicking down an air hose with one locking end, so i can do both tires on one side with one hook-up.
    since i don't expect to air up more than twice per tank, there won't be enough pressure to cause damage. i don't rock-crawl, so i'm comfortable. it's mostly for the trip from the trail to civilization, where i can top-off the tires if i need to.

    I'm working on the same thing, converting an ac compressor to on-board air compressor with tanks, to run air tools. I've seen and recommend using a York compressor over your stock compressor, though. Stock won't have as much output as a York... I picked up a F**d York at a junkyard, and I can actually feel huge suction when I rotate it by hand. Plus, it can be mounted at almost any angle except upside down, and has it's own oil supply that shouldn't contaminate the air output as much as a Delco would...
    Here's a real good write-up from a Heeper on this, even has an itemized cost list: http://k5.8m.com What more is there to life?**

    OK. Everyone mentions explosions? Any pictures?
    Seems to me that you might suffer a split seam with 100-150 psi but an explosion.....?
    And where are you mounting your air tanks? On the frame rail under the cab? You run more risk of hitting the tanks there IMO.

    I've never seen one explode myself, but I've heard enough to know I'd rather not have one explode.

    Here's a story of a big ole tank that wasn't welded right, but still implies the force generated at low PSI: <A target="_blank" HREF=http://www.gomr.mms.gov/homepg/offshore/safety/safealt/SA_136.html>http://www.gomr.mms.gov/homepg/offshore/safety/safealt/SA_136.html</A>.

    Here's a photo of a tank, but I don't know the PSI or anything behind it (it's part of an ad for something else): http://detnews.com/specialreports/2000/firedept/equip/equip.htm.

    Read about half way down the page here at what happened to a guy using his spare as a tank:http://www.rootsweb.com/~wvcabell/killed.html.

    This is just from a tire explosion, but I can't imagine they tried to go higher than 100 PSI: <A target="_blank" HREF=http://www.tireaccidents.com/tire_explosion_kills_garage_owner.htm>http://www.tireaccidents.com/tire_explosion_kills_garage_owner.htm</A>.

    I'm sure there are good photos out there, but I have to keep stopping to work...

    I agree, though, that underneath at the frame rail is a risk area too, unless you have a nerf or something protecting it...

    The pictures from Detroit Fire Department are of a 2216 psi bottle. Seeing that, imagine how it feels wearing one on your back in a burning buildng[​IMG] They are actually safe, as long as they are hydro-tested every two years, and disposed of in 15. A whole degree of fear enters when you realize that the city buys these things from the lowest possible bidder!

    If it weren't for bad luck, I'd have no luck at all[​IMG]

    I knew it was a higher pressure! But even so, 100PSI can still do some damage.
    I just went back and read the rest of that article. Apparently, the city doesn't stop at buying from the lowest bidder! They've cancelled maintenance contracts, equipment testing, etc....

    Yield2me, BTW, if you do end up using your bumpers, make sure you use rounded (concave or convex?) ends. With flat ends, the air will try to push out and make round, probably resulting in premature tank failure... Learned that one on CK5[​IMG]

    Say, saw your post and I have been going to do this same thing for a long time. The ones I have seen have been made of regular black pipe with a couple of 3/8" caps welded on the ends. They seem to work really well. As far as the power units to air them up, most I have seen have been suspension pumps out of the larger cars(Lincoln-Cadillac). I have seen some set up with gauges set up in the dash to monitor what was going on and even have seen some of the level ride shocks adapted to make your wheels go up or down when needed. Makes a slick setup!! I see allot of people worried about the pressure and explosions. I don't want to step on any toes, but for an onboard tank I would not think anyone would go over 150 lbs psi. I know I have buddies who just carry liquid CO2 bottles to do all of their air needs. Now that is pressure, and it doesn't take that much air to air up a tire or blow out a dirty part or something. On the trails I think that is a little overkill. Anyway, that is my $.02 worth. Hope this helps!

    If you are going to try to run air tools, I would recommend what Newyorkin is trying to do. The York Compressor is by far your best bet. I live out here in the sticks where every farmer has one of these setups on their field wagons, to repair their Tractors and Farm Implements when they break down in the middle of no where. Most of them use old propane tanks for holding tanks and very few ever run more than 200 psi. Those work good for that application, but as far as a bumper, it would be a little impractical. Just my $.02 worth.
