I am fortunate to have several good resources for materials and tools very close to my work location in Houston. Today I picked up three 10' pieces of 3" X 3" X 1/4" angle iron, and two 6' hinges that will be used to construct my "Dave Clay" bending brake. The hinges are 0.060" gauge steel, 2-1/2" width, 1" pitch, 1/8" knuckle.
