Taking over the reins on the CNC mill, Brad Lagman began to map out our assault on the block. After setting the cutting tool and with the touch of a button, Lagman ordered an immediate 0.030-inch be removed from each cylinder to a depth of 5.900 inches. Not only did the CNC bore each cylinder to precise specs, it also bored deep enough to clearance for the honing process. After boring, the CNC head moved over 0.0010-inch and dropped to a depth of 6.200 inches. From there, a step-notch is created in the bottom of each cylinder, allowing the bore-honing stones ample room to spin, once again eliminating bore taper and broken stones.
