With the box section 'inside' the shroud and the heavy angle above, it was all clamped to the bench before I used a length of 1/8-inch plate to force the steel downwards to form the angled edge of the shroud. A second bend was then formed as shown previously to complete the 'box.' The same technique was used to form an angle on the other side of the shroud, albeit a longer section. These angles are an attempt at creating airflow to the fan, rather than just have the shroud as a square box. View Related Article
