8. Operation
On the side of the chuck body there is a hole for the blind
set screw, Fig 8.5. Insert the protective leather disc into
the hole, ensuring it is positioned to be touching the
insert thread as shown in Fig 8.6.
Warning: It is essential that the protective
leather disc is used in order to stop the insert
thread being damaged by the blind set screw.
Insert the blind set screw so it is positioned as shown in
Fig 8.6.
Tighten the blind set screw to hold the chuck insert in
place using the 3 mm hex wrench.
The chuck can now be mounted to the lathe as shown
in Fig 8.7 by threading it carefully onto the spindle until
the insert meets the face of the shoulder on the
spindle nose.
Inserts with certain thread sizes feature a tapped hole
on their collar and are supplied with a protective leather
disc and M6 x 6 blind set screw. This allows the insert to
be secured to the lathe spindle, meaning the chuck can
be used on a lathe capable of reverse turning. See the
chapter Contents of the Packages for a list of these
inserts.
If the lathe is to be used in reverse, the chuck must be
secured to the spindle to prevent it from coming loose
during operation. When the chuck is fully threaded onto
the lathe spindle, place the protective leather pad in the
hole on the side of the insert, thread in the M6 x 6 blind
set screw and tighten, Fig 8.8.
Kg
Warning: Only use the specified inserts for
reverse turning. Inserts which do not feature a
tapped hole for a securing screw cannot be used
safely if the lathe direction is reversed.
