before inserting center to ensure a good fit

5. Make sure center of quill lock handle is
aligned with quill keyway to ensure tailstock
center and quill will not freely rotate under
load (see

6. Secure quill in place by re-tightening quill lock
handle.
Removing Tailstock Center
1. Loosen quill lock handle.
2. Hold a clean rag under spindle or wear a
glove to catch center when you remove it.
3. Rotate handwheel counterclockwise—
tailstock quill will retract back into quill, caus-
ing center to be forced out.
Tailstock quill must always be locked in
place during lathe operation. Before tight-
ening quill lock handle, it must be prop-
erly aligned with quill keyway. Otherwise,
workpiece can be thrown from lathe caus-
ing serious personal injury or death.
