[TheForge] scrap plate steel

[debmiller at fuse.net]

Fire and water is the answer.

I have watched trained guys straighten beams, plates, etc using a rosebud toch and a bucket of water. Kind of like a REALLY, REALLY large shrinking hammer.

I am sure there are probably some process description on the internet.

In basic terms it was a matter of heating the opposite side and then cooling with water and shrinking the "dimple".
