To dress a claw bar, as shown in , when badly worn or broken, heat to a deep yellowheat, then forge to shape, as illustrated by side view 172 THE TWENTIETH CENTURY in figure, then close the claws, as a, a, front view infigure, to within % of an inch apart at the extremeends. Now have a fuller as Fig. 103, which should be Front End view. Side 101. Illustrating claw bar. Ys wider than the body of a railroad spike, and drivethe fuller down between the claws.
