The groove on the base
jaw is tapered. This groove
is where the Top Jaw sits
and is pulled in with two

countersunk screws. The

taper allows for

the top jaws to

have a snug fit

but will not

damage either

the top or
base jaw.

The STRONGHOLD is equipped with

ONEWAY

's  patented profile top jaw shape. This

shape increases gripping power at all diameters
of round and  square stock. Less wood damage
also occurs with this jaw shape than
with the conventional round
shaped jaws. 

SLOT (patented

safety feature)

This is a slot which is milled
onto the body of the chuck.
There is a shorter slot under the
opposite jaw, which can't be
seen in this view. Refer to page
13 for the functions of these
slots.

FEATURES OF YOUR CHUCK

Note the recess: This is
where the groove around
the diameter of the head
of the screw fits. This
eliminates the possibility
of the screw moving in
or out of the chuck. 

Note the shape of the tip of the
base jaw: this fits into the
grooves or flats that are milled
along the length of the head of
the screw which prevents the
screw from spinning.

WHY YOU HAVE BOUGHT A SUPERIOR CHUCK BY BUYING

THE STRONGHOLD:

•Base jaws are made from carbon steel. Precision grinding on the sides pro-

vides for the exact and controlled clearances which are required for wood

turning chucks.

•Base jaws are case hardened which makes them longer lasting, stronger, and

non-seizing in use.

•Scroll is precision machined and case hardened. The bore is honed to exact

tolerances after heat treating.

•The scroll is manganese phosphate plated which acts as an anti-seize com-

pound. Less lubrication is consequently required for smooth running action

over the life of the chuck. 

•The body is precision machined. Electroless nickel plating provides a hard

wearing surface for base jaws and scroll while giving the added bonus of

providing excellent corrosion resistance. 

Add these quality materials and precision processes to features such as:

•Profiled Top Jaws

•Patented Safety Feature allowing maximum travel

•Key operation allowing one handed tightening and solid holding power

•Superior taperlock adaptor

•and its one-of-a-kind woodworm screw

all at a competitive price  -  gives you an absolutely superior chuck.
