5.Making sure the spur center is aligned with the workpiece center you marked earlier, drive the spur center least 1⁄4" into the end of the workpiece (Figure 32).

6.With the workpiece still attached, insert the spur center into the headstock spindle (refer to Installing/Removing Headstock Center on Page 22 for additional instructions).
Note: Use the tool rest to support the opposite end of the workpiece so that the workpiece and spur center do not separate.
7.Install the live center into the tailstock quill and tighten the quill lock handle to lock the quill in position (refer to Page 23 for addi- tional instructions).
8.Slide the tailstock toward the workpiece until the point of the live center touches the workpiece center mark, then lock the tailstock in this position.
9.Loosen the quill lock handle and rotate the tailstock handwheel to push the live center into the workpiece at least a 1⁄4".
Model G0694 (Mfg. Since 1/09)
Do not press the workpiece too firmly with the tailstock or the bearings will bind and overheat. Likewise, do not adjust too loosely or the workpiece will spin off the lathe. Use good reason and care, otherwise, serious personal injury could result.
10.Position the tool rest approximately 1⁄4" away from the workpiece and approximately 1⁄8" above the workpiece center line (Figure 33).

11.Before beginning lathe operation, rotate the workpiece by hand to ensure that there is safe clearance through the full rotation.
Keep the turning tool on the tool rest the ENTIRE time that it is in contact with the workpiece. Otherwise, the spinning workpiece could force the lathe tool out of your hands or entangle your hands with the workpiece.
