4-Jaw Self-Centering Chuck
25MM JAWS
These jaws are used for expansion into small recesses and for firm holding
of fine spindle work, such as earrings, chess pieces, etc.. To turn very small
articles, the jaws can be unscrewed and the backing jaws only can be
used.
DOVETAIL JAWS
Dovetail jaws are designed for mounting bowls by expanding into a recess
or clamping onto a spigot. The size indicated is the outside measurement
of the jaw face when fully closed. Dovetail jaws provide approximately
25mm of expansion beyond their specified size.

KEY CHUCK
The 4-Jaw Chucks provide one-hand tightening along with tremendous
griping power provided by the 6 to 1 ratio of the scroll. The totally enclosed
back assures consistent, smooth action by preventing dust and debris from
getting into scroll of the Chuck.
Key chuck cannot be beaten when it comes to holding power.
Its compact size makes it ideal for use on 300mm capacity lathes or
smaller.

CLAMP-MODE
With this application the workpiece is held by the jaws. To achieve a good
hold, press the bowl end hard against the jaws. Fasten the workpiece to
the screw or onto a face plate. When pre-turning bowls from green timber it
is possible to do this between centers or with a pivot chuck. Turn a 5 to
10mm deep dovetail recess first.

EXPANSION MODE
For this application arecess is turned into thework piece. The depth ofthe
recess depends on the actual size of the workpiece as well as the type
oftimber used. The minimum depth should be 5mm to 10mm.
MAINTENANCE
The chuck is engineered to close tolerances and may initially be stiff to
operate. With use movement will be easier.To maintain easy jaw action,
regularly spray oil into the scroll and work Key chuck through full range of
movement. Inspect chuck regularly for build-up of dust in the scroll and
jaws.Clean as required.
BEGINNER'S HINTS
