Our first attempt to machine the taper out of the crosshead guide bar ends. The black marker helps indicate the cut. We expected the cut to start at the end, where the taper is, but the cutter marks are across the complete bar, indicating something is not right. We take the guide bar out, check to see if the reference surface on the parallel in the vice is true and find it is not, and find the end of the bar is bent from relieved stress.
