To align the cutting tool with the tailstock
center:
1. Mount the cutting tool in the tool post, then
turn the tool post so the tooling faces the
tailstock.
2. Install a center in the tailstock, and position
the center tip near the tip of the cutting tool.
3. Lock the tailstock and quill in place.
4. Adjust the height of the cutting tool with a
steel shim, so the tip just touches the end of
the tailstock center, as shown in Figure 74.
