Personally, I'd leave making an air tank to the professionals. /wwwthreads_images/icons/crazy.gif Probably not the answer you wanted to hear, but if the welds aren't really good on there you could have a serious issue when pressured up to max... I think I'd go with at least 3/16". You should use rounded caps on the ends too. It helps with the pressure. Look at the store bought tanks, design yours after one of those... /wwwthreads_images/icons/crazy.gif The other thing is you'll need quite a large piece of pipe to get it to store a decent amount of air... /wwwthreads_images/icons/crazy.gif

The tube I was going to use is around 6" x 25", which comes up to about 3 gallons. Not really wanting to hold a lot of air, just as a buffer for running an air compressor.

go to a truck junk yard and get an alum tank off of a tractor. They are super light and hold up to 300 lbs.

Can someone please bring me a hammer my 33's just ate my fender again. Damn i need more lift.

 

I'd go with a factory made tank too. It will cost you less (most likely) and they are pressure tested. If it has a max 300 PSI rating, it probably means it will breach at around 900psi, or more.
Anyways, you never know with a home made tank, you could be filling it for the first time, and only get 50 psi in it before it goes nuke.

Do you think insurance will cover the carb if it some how "teleports" behind the tires of a 350 with dualies?

 

I went down to Wally Mart the other day and got a 7 gal air tank with hose / guage / pop off safety valve and on/off valve for under 30 bucks .

I use an old fire extinguisher bottle. They hold great and come in different sizes. Check those out.

That is a great idea, you could put disconnects on it and make it portable! (OR more portable, I guess)

Portable? I don't think it's worth it.

If you just want to move the tank from one vehicle to the other. Get one for each vehicle since they're dirt-cheap. The quick disconnects alone will be more expensive than a used bottle.

If you mean portable in the sense that you fill it with air and take it along to another vehicle then it won't work. The amount of air they hold is very small compared to CO2 tanks. Even the biggest fire extinguisher bottle you can fit under the hood will not fill a 33".
