Well there are several ways..i prefer filled to the brim with water, but I have used the cheap way..connect a hose from your cars exhaust to the tank and make the first cut at an 90 degree angle. I am still above the grass..so it must work.

in Mesa..but I dont have the equipment  to do it. We used to solder/weld up gas tanks using both methods..its not hard..Ya just have to make sure there is no combustible gases..Absence of Oxygen in the Tank is your Friend, the combo of O2 and Gas makes your wife a widow. A 90 degree cut blows the gas outwards.., straight in ..bad news. I must advise that you take your project to someone that knows what He is doing. Best wishes and Good Luck

It's done all the time by many means.........found this version on the web of course. http://www.associatedcontent.com/article/2113397/how_to_safely_cut_open_a_propane_tank.html

I found an artical a year ago from the gas industry that stated as long as you filled it a couple of time with water and let drain and dry for a few days no gas should be left...but who knows...

We have one (250 propane tank)that has been sitting empty for a year now and are about to carve it up, so we are going to use Co2 extinguisher to fill the void before I let teamate Shorty spark away.  I would do it myself but don't want to take the GLORY away from him...............hhhmmmmm I hope telephoto lense will be able to see him in orbit....?

Oh one more thing........a metal fabricator turned me onto a trick of drilling a 1/4" hole where you want to start torching so as not to overheat the area...that way it starts cutting almost at the start without warping....

I did the water thing to the rim, but still smelled LPG vapor so I filled with CO2 from my Kegerator back up Co2 bottle (dense, inert, non flammable gas) before cutting mine.   It was no problem but the pucker factor was quite high on the initial drop in.................

My sons built my grill and they filled it with water and drained, they then used an angle grinder to cut out the holes for door and firebox. It let a smooth straight cut.

Try filling it with water and drain a couple of times, then put 20 to 30 gal. of water and dry ice. This will fill the tank with co2. safe as can be from that point on. I've had several oil and fuel tanks that i needed to cut and never had a problem.

TEDDY, You can still find tanks up here that were burned during the RODEO-CHEDISKY fire years ago! I have 2 and still need to pick up 2 more from my guy in TAYLOR! He sold his house and i have a week or so to get them out of there ! FYI- I used and angle grinder on mine and had no problems with backflash but these tanks sat around for 5 years after the fire!

The county up here is having an auction next weekend, according to the paper they are selling propane tanks. This is in the Springerville Eagar area. Here is the link to the ad: http://www.wmicentral.com/public_notices/local_legal/apache-county-surplus-auction/article_2d7f1a26-eae1-11e0-8c44-001cc4c03286.html I am going to go view them to see if they are worth buying.

That's pretty cool.  I wonder how many tanks they have?  It just says "1 lot propane tanks"
