A glass sheet used in the making of an aircraft windshield is shaped using the 'cut-to-size' method instead of the 'out-after-bend' method. In a preferred aspect of the invention the 'cut-to-size' method is practiced using a bending iron having a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position.

A sheet bending device includes a sheet shaping rail having a stationary shaping rail portion mounted on a support member and an articulating shaping rail portion pivotally mounted on the support member for movement from a non-shaping position to a shaping position. A retention member limits movement of a sheet to be shaped relative to the stationary shaping rail portion when the articulating shaping rail portion moves to the shaping position. A 'cut-to-size' method is also disclosed to shape a sheet for use in making an aircraft transparency.
