I recently saw an interesting DIY way of bending big sections of structural steel with just an OA torch. This is done on the piece before it's connected to the building. (The ends need to be free to move.) They mark off a wedge on the piece with the wide end of the wedge facing the inside of the desired bend. They heat just the wedge area with an OA torch so that it gets red hot. The nearly molten metal in the wedge is constrained by the surrounding unheated metal so it deforms, then as it cools it pulls togather to make a slight bend. This is repeated along the length of the piece until the desired curve is obtained.
But this was done on a big structural steel angle. Would the same technique likely work with 1 x 1 x 1/8" type 304 stainless angle? I need to bend it the "hard way" e.g. with the leg pointing to the inside of the curve. Warping in unintended directions would be unacceptable. Slight changes in angle leg thickness would be OK.
