    cutting heating oil tank

    I've cut the 500 gal ones with a torch/plasma cutter. Just leave it vented. Oil doesn't explode just burns really. But it's your call if you feel comfortable.

      I have done it several times in building pig cookers..

      but prepped them first by steaming them out with a steam jenny to get the crud loose...

      I like the round oil tanks best for that purpose...

      run the sawzall slowly with a coarse metal blade and have somebody give it a squirt of WD40 from time to time to cool the blade.. (white smoke is good)

      also I usually tack weld a length of angle iron to the tank to be a saw guide...

      Word of caution... do not run the blade fast... you will knock off the teeth in nothing flat...

        I turned the tank on it side and used my plasma and a come alongs snug cable to set the torch on and ride around the tank. Only had to move the come a long one tine brcause of the cranking mechinsm. Measured up from the concrete floor to get the cable level. My tank sprung when it was cut free, if I was to do it again I would run a 1/4" rod through the sides of the tank I was using and weld both sides to prevent the tank from springing open.

        wear ear protection, a jig saw with the right blade might be easier to control.

          I don't see a problem with it.

            I would think using a good jigsaw with the right blade would be more accurate and easier to work with.

            I should have run a couple rods through mine and welded them in-place, when the halves separated the ends sprang open.

            I used my come alongs' snugged cable for a straight edge. I turned the tank on it's side an measured up from the shop floor to get a level cut and straight cut.

                  Why? To ensure you allowed enough air into the tank to get that perfect oxy-to-fuel explosive ratio?

                    fill with water and use air tool grinder or sawzall.

                      Do not cut the tank with a torch or plasma cutter without purging with inert gas or filling with water. The heat will vaporize remaining liquid and create an explosive atmosphere inside the tank. Only use a sawzall if you can have someone keep soapy water on the blade the whole time you are cutting and a slower speed with good blades. This way no heat to vaporize the fuel. Oh a co2 extinguisher can be used as a purge gas if one is laying around plus nitrogen or argon will work also. Good luck..................

                        It was a 500 gal oil tank. It had been sitting for a couple years and in case you didn't know oil burns not explodes. Ya the oil burned inside it but no explosions.

                          It's an oil tank. Oil burns not explodes.

                            Dump a pound or two of dry ice in or dump a c02 extinguisher in before you do either....
