Dies Fig. 12 bend the pieces of 5^ x 3inch iron for tender truck braces. Thecorrect duplication of these pieces wouldmake the dies almost indispensable, evenif the cost was greater than by the oldmethod at the anvil. This is one of the jobs that deceivesby its apparent simplicity, while it is reallya difTicult thing to shape and bring theends to the proper angle, without moreor less fitting when done by hand. Thedies turn out these parts ready to be as-sembled without any further work what-ever, they going to place and fitting prop-erly at once, when the dies are of correctshape to produce this result.
