My door sprung

I don't understand. How can a rectangular opening in a tank spring open in a corner?

well it happened. I am building a 120 gallon tank reverse flow smoker, and last night we cut the opening for the door, well it sprung open in one corner. How do I fix this? I have no photos but it is only popped open about a 1/4 in or less.

First off I don't think a 1/4 or less, will be a big problem by the time all the rest of the hardware is on, if you are planning on welding strap around the lid for a better fit. You may want to tack weld on the back side of the door a section of angle or rod to each side and clamp it just before you tack them on after adjusting it for the gap and making sure it is square, Leave them in place until you have welded the strap on, make sure you weld in small lengths then alternate to the other side or top to bottom to prevent heat build up and further warping. This is how I may do it but I am sure there are better ways to handle it so I hope someone else that knows more about this will chime in.

I assumed it was the door its self he was talking about and not the tank not that it could not happen, especially if he used a cutting torch.

Had to deal with this a time or two and resolved it by welding a chain to it and the opposing corners, heating the metal then using a com- a- long or ratchet strap deal to bring it into shape.
