TOOL SET UP
Clamp the turning tool into the tool holder.
The tool must be clamped firmly. When turning, the tool has a tendency to
bend under the cutting force generated during the chip formation.
For best results, tool overhang should be kept to a minimum of 3/8" or less.
The cutting angle is correct when the cutting edge is in line with the center
axis of the workpiece. The correct height of the tool can be achieved by
comparing the tool point with the point of the center-mounted in the
tailstock. If necessary, use steel spacer shims under the tool to get the
required height. (Fig. 14)
