I was a little disappointed to see that NEC 358.24 only says that bends "be made so that the tubing is not damaged." I suppose, though, that the further specification that the radius "shall not be less..." could apply to finding a violation to the sort of free-hand bending as is shown in this photo.

Why spend $8 for a bender, when you can tweak the pipe between studs, bricks, or a handy bumper? :-(
