Fay Butler demonstrates how to smooth a piece of sheet metal using the Yoder Power Hammer. Smoothing is accomplished by using two hardened steel dies; a flat surface on the top and some radius on the bottom. By averaging out the curves on the part, a larger radius bottom die can often be used. Transitioning a radius highlight line into a flat will require some stretching of the flat area. Checking the part to your pattern may indicate areas requiring more form and/or shaping.
