The Four Jaw Self Centring Chuck is a precisely made workholding device, which utilises

the precision, simplicity and reliability of the engineering chuck. The purpose of this

booklet is to show how it has been successfully adapted to enable you, the woodturner, to

benefit from its great versatility in terms of gripping power, concentricity and capacity.

maintenance is minimal, and the chuck, if it is used correctly, should give a lifetime of

accurate and reliable service.

WARNING!!

Mounting the Chuck to the Backplate

The backplate is the bossed disc, internally threaded to suit the headstock of your lathe. It

carries a register diameter which accurately locates in the rear face of the chuck body and

ensures perfect concentricity. The chuck body is secured to the backplate with three M8

socket head cap screws. When fitting the backplate to the chuck, ensure that the register

diameter is located fully and both chuck and backplate faces are together. A light tap with a

soft faced hammer may be necessary to ensure full engagement. The securing screws

should be tightened in stages with the 6mm hex key wrench provided.

The periphery of the blackplate carries 24 of 5mm diameter holes which may be used for

indexing to provide accurate spacing for spokes? or decoration work, etc.

Mounting the Chuck to the Lathe

The chuck backplate is precisely machined to fit the headstock of your lathe and the chuck

should screw firmly and fully into position. It may be necessary to restrain the headstock

shaft whilst finally screwing the chuck home and a suitably sized paper washer placed on

the headstock spindle will greatly assist chuck removal. Always ensure power to the lathe is

off when fitting or removing the chuck and never fit or remove the chuck by running the

lathe and holding the chuck, serious injury could result. To unscrew the chuck, the

headstock shaft should be locked or restrained and the chuck key given a tug or a sharp

tap with a soft hammer or a block of wood. Great care should be exercised when removing

the chuck from the headstock as the sudden weight drop could cause damage or injury. If

your lathe is reversible, care should be exercised - a lockable backplate is available if

required.
