damage) and screw in insert using the optional accessory spanner or a 1 1/2” AF spanner. Care

needs to be taken that the outer male insert thread is engaged properly at the start with the

female body thread. Screw insert fully into body recess. This is important to ensure running. Refer

to FIGURE 2.

CHUCK INSERT SPANNER:

An optional, accessory insert spanner can be purchased to

help wind the inserts into the chuck to remove from the

lathe spindle. (Code 23014). See back of manual for

further information.

The Insert can now be

locked to chuck body by

means of the M6 x 6

grubscrew provided. Make

sure that the fibre washer

is inserted first to act as a

buffer between the

grubscrew and insert thread.

DO NOT SCREW IN GRUBSCREW BEFORE INSERT IS

SCREWED HOME IN CHUCK.

IMPORTANT: LH THREAD INSERTS MUST BE LOCKED

TO CHUCK BODY OR CHUCK BODY COULD UNWIND

FROM INSERT.

FITTING CHUCK TO LATHE

Correct fitting of chuck to lathe spindle is important to

ensure accuracy. The chuck body must

contact an accurate shoulder on the lathe spindle or bearings (as on Teknatool Nova 3000) to

ensure chuck will run true.

There can be a wide variety of lathe spindle thread and spigot dimensions even within the same

thread size. The internal thread size is kept to standard tolerances. The internal thread length and

spigots of Nova inserts are manufactured to cover as wide a range of variations as possible. This

will mean that in most situations you should be able to get a satisfactory match.

CHECK THE FOLLOWING:

Although the insert may screw on part way it may not contact properly with spindle spigot - a

spacer or some further modification of the insert may be necessary. This would be the

responsibility of the chuck user. Make sure the chuck is screwed to lathe thread properly -a good

check is to see whether it screws home on the spindle the same as another lathe fixture such as

a faceplate.

POOR FIT OF CHUCK TO LATHE SPINDLE CREATES A SERIOUS HAZARD WHERE

CHUCK COULD DISLODGE FROM LATHE. DO NOT ATTEMPT TO USE CHUCK UNLESS

THE CHUCK US CORRECTLY FITTED TO LATHE SPINDLE.
