8. Operation
Fig 8.13
Important
Both the SC1 and SC2 chucks are made to very
tight tolerances to ensure extremely accurate
performance. On both chucks the permissible
axial run-out is 0.1 mm and the permissible
i
radial run-out is 0.15 mm. To ensure the chucks
perform as accurately as possible, the jaws must
be mounted correctly so as to minimise run-out.
Match each jaw with its corresponding slide and carefully
attach them as shown in Fig 8.13. Only loosely secure
the jaws so that some movement is possible.
Now close the jaws together fully and they will self-
centralise on the jaw slides and perform with optimum
accuracy. Tighten the screws to complete installation.
Once the jaws are attached to the chuck body, thread the
chuck onto the lathe spindle as previously shown.

Warning: Before turning any workpiece using
any method described in this manual, ensure the
timber is free from any cracks, splits or other
defects which may cause it to break apart
during turning. Also ensure that the workpiece
i
is securely held by the chuck before turning is
carried out.
