Now that my POS truck runs and wheels reliably (after i fix it again of course)
I want to make an onboard air tank. Is there a cost efficient way of doing this? Say weld or bolt a good size propane bottle underneath (i have alot of room) and run lines off it? i don't need to run anything awesome or anything. Just something to have about 300psi of air handy or so when i air up or happen to blow a bead. School me on air tanks please. I'm stupid.
i got mine off ebay its just a simple 5 gallon tank of a 18 wheeler trailer with a 250psi max, i think it was $9 then like 15 sp&H
sweet...send me a link.

thats all i could find for now, there are bigger one with higher pressure ratings somewhere
sweet.
The picture is really dark...what all does it look like? do you have a pic of yours? Also, if i keep this tank at 150-165psi, it wouldn't have any problem airing up all 4 of my tires from 8 back to 20psi would it?
Well i found the 8.5 and 12 gallon tanks on ebay. My buddy says he has some tanks laying around that i may be able to have...so i'll check that out first. My question is that if i fill up a ~10 gallon tank to 170psi how many tires will this air up? How big a tank do i really need? of course i'll go home today and see exactly how big a tank i can fit. Most i'll ever do with it is probably air up tires and put tires back on the bead every now and then. Maybe have an airhorn...but prolly not. We have a big compressor that will push out 180psi here at the shop, so filling it will never be a problem.
Boyles' law
p1v1=p2v2
volume of your tire=a cylinder 38" diameter and 15" tall minus a cylinder 15" in diameter and 15" tall
volume of your cylinder=231 cubic inches/gallon
pressure has to be in atmospheres: 1 psi= 0.068046 atmosphere
onlineconversion.com is your friend!
you can always build a CO2 tank setup for pretty cheap. Botco has the regulators, you can get the tank on ebay (harbor frieght had one in the close out section as well recently), and the hoses and fittings can be had cheap at HF as well
ok....tell me about that.
ya CO2 would be your best bet if all u want to do is air up tires
IF you want to see one you can come over sometime and look at mine. The tank is the hardest part to get. Ebay is a good source. You can get 5, 10, and 20lb tanks. I run a 5lb. I just had it filled for the first time, so I can't say how long it will last, but I know it will last much longer than a normal air tank. Creighton has been using one for a while, so maybe he can give you more info on how long they last. You may also be able to "liberate" a tank from a convienence store or something simillar. They're used to run the fountain drink machine. Then get a 100psi regulator from botco. They had several on the wall over by the welders last time I was there. Then go to Harbor freight and pick one of those hose kits that come with all the fittings, and a gauge if you want it, and you're good to go. The nice thing is, these things are relatively small and compact, plus they're mobile, so you can carry them to other rigs. As for price, I bought the tank for $40, the regulator was around $40, and the hose kit was $15 (but I got the one with the better hose). I think it was 9 bucks to fill it at brazos valley welding supply on 2818. I built my own mount for it. Here is a pic

Supposedly you can also run air tools with this setup, but I don't know if the regulator from botco will work for that or not. Perhaps do a search on pirate for more info. Another thought on the tank. Maybe try checking with Brazos valley welding supply and see if they will rent you a tank for a few dollars a month, and then you could just come trade it in for a full one when its empty
