Home made air tank?

David H
Can you email me the particulars on what is needed to do the CO 2 tank for air?
What regulator and what thread for the tank.
What valves needed
What tanks to look for.

If you have a tank and reg setup I would be interested in purchasing

email or post on here

I suggest you use a 10 or 20 lb CO2 tank for airing truck tires on the trail. I have airtanks and they are great for my ATV tires but will only fill 2 15" truck tires. A 20 lb CO2 will fill approximately 60 full size 15 " truck tires. Go to the Powertank website for info. Powertanks cost $400 but you can put together your own for under $50 (I have done it several times). New regulator with 125 PSI spring is $35, used tanks are not hard to find (I have purchased about 20 and never paid more than $5). Hose and a quick coupler and air chuck and you are ready. I pay $12 (Modesto,CA) to get my bottles filled.

I have a co2 tank.. love it. Only thing I have seen that is better is the York OBA.

I have one of those I bought off the Matco truck years ago when I was wrenching for a living. There are two things wrong with that theory:

1) Without a check valve, which an air hold hose doesn't have, the cylinder will suck the air right back out as soon as the piston goes on the downstroke.

2) If you do find a way to make it work, you now have a highly compressed container of volatile gasoline vapor. Can you say "BOOM?"

With today's MPFI, you could just pull the wires from the injector on that cylinder and then run it a bit that way to discharge any fuel residue that had been in there. Then use it as a pump.

I will second the york engine driven on board air system, I have a 12 gallon feeding my air bags and the york does go through oil but after the seals break in that wont be a problem and with my oil and water trap that will never become an issue with oil in my airbags or comming out of my valves, or in your case your tires more than likely, plus, being able to use air tools!?!?!? can we say **** yes! Use a 5 gallon or less and youll have rediculously fast refill times compaired to anything elsectric, private message me if you want me to throw you in the right direction, if you can make your own bracket I'll show you vendors and was you can keep the whole project under 450 dollars including tank and fittings and everything needed. maybe even under 400. and if you have an older used compressor. alot cheaper than that.

see ya!

Everyone keeps talking about cheap Chinese Air Tanks.

Anyone have any recommendations on where to locate a replacement 30 Gal air tank for a 3HP air compressor.

One of my older compressors has developed a pin hole leak in the bottom of the tank. The leak is not on the welded seam, so I suspect that the base metal has deteriorated. If it was on a seam, I'd probably just re-tig the seam, but since it's in the base metal, I have to assume the tank has gone bad.

The replacement tanks I've been looking at are in the $230 range, which is over half the cost of a replacement compressor (same ratings).

Suggestions?

[whateg0]

Try a cheap HF compressor. Discard the compressor and motor and use the tank. Just a thought.

edit: never mind, I just looked. The cheapest 29 gal compressor is $250. Of course, you could still get it and you'd just have an extra motor for something

Nice advice, Zrexxer. It's so simple and practical.

A portable air tank won't fill 4 truck tires! Not very practical when he needs more air on a trail!. Even a tiny 5 lb CO2 will air up 15 or more tires and is way more compact.

For that matter, neither will a "5 gallon" propane tank - the original poster's proposal, which is what I was replying to.

I made air tanks for my offroader years back!
What I did was picked up some 4"dia round tubing 1/8" thick x 6'.
capped the ends and installed a coupler.
I made two for the front and two for the back.

you guessed it heavy duty bumpers, with a second purpose.
if memory serves my correct, I had to run them about 90psi, to air my 33's back up.
Before you ask, They were hit several times by and tree's and rocks and never failed me.

The guy who bought my rig loved it.

[DavidLH]

Zrexxer, that's why I like my CO2. Propane tanks and air tanks won't do the job (not enough volume).
Lawnguy, bumpers won't work for me either, my tank is 5 1/2 by 18 inches and weighs 12 lbs full, very easy to pack and use and as I said , it will fill 16 tires! I have even reseated tires with it. I don't think the "bumper tanks" would do that :-)

[lawn guy]

yes, they will.
Actully I had air them up before to 200psi.
you learn many trick on the trail.
I had a electric 12 volt pump in the truck to air up the the 2 tanks incase of emergeny, but it took forever.

it really doesnt take much to reseat the tire beads.
I have used ratch straps a few times to do it.

[BWS29128]

I made my friend one from a piece of sch80 6" pipe that also doubles as his bumper. Old #20 propane tanks make great bead seaters.

I did exactly the same thing for my Dakota, 'cept I used Sch40. I figured it would bend before it broke (exploded) and wouldn't end up mattering. I keep it at about 75psi and check it and refill it every now and again....so far I've only had to air up the front two tires after a particularly rough trip through the fields, so I don't really know how many tires I could fill if I had to. Hmm....
