    Default 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?
