JUMBO JAWS

For finishing the backside of your bowls up to 12" in diameter, the Jumbo
Jaws are unsurpassed. Jumbo Jaws are aluminum plates machined from the
solid for higher strength. Buttons are hard rubber sleeves pressed on taper
steel cores and can be positioned at virtually any diameter. Extra button sets
are also available and can be stacked to hold uneven or out of round bowls. 

MEGA JUMBO JAWS

For larger bowls, up to 16", if your lathe has the capacity, go for the  Mega
Jumbo Jaws.

EXTRA BUTTON SET

For large, or odd shaped bowls, an extra button set is available which allows
buttons to be stacked. 

JUMBO SCREWS

An 1-1/2" Left Hand Jumbo Screw is available for outboard turning (this
screw is the same length as the R.H. screw which is supplied with the
STRONGHOLD). For large bowls, the 2" screw should be used (R.H. for
inboard and L.H. for outboard turning). Having trouble differentiating right
hand and left hand screws?  See page 18.

COLLETT JAWS & PADS

For turning very long slender parts, consider the collett jaws and pads. They
are extremely safe and hold with a bulldog grip any part within their capaci-
ty. Collett Pads come in sizes of 1/2", 3/4", 1", 1-1/4", and 1-1/2".

CHUCK SPURS

If you often switch from chuck work, to working between centres, consider a

ONEWAY

chuck spur. It mounts directly into your chuck, which eliminates

having to remove and re-install your chuck from your spindle. Chuck Spurs
are manufactured in two sizes;  1/2" and 1".

SECTION 4 - STRONGHOLD ACCESSORIES

Right out of the box, the STRONGHOLD will be ready to be used for most

turning applications. The accessories which 

ONEWAY

offers were designed

to allow the wood turner to take on projects which may require a smaller or

larger capacity than what the standard  No. 2 Jaws can handle. The following

is a list of available accessories which will allow you to easily upgrade and diver-

sify your STRONGHOLD.

No. 1 JAWS

If often turning small parts, the

No. 1 jaws are a must, but do

not use them for material over

1-1/2" in diameter or for bowls

with recess larger than 1-3/4"

in diameter.

No. 3 JAWS

For large bowls (over 12" in

diameter and 5" deep), No. 3

jaws are an asset because their

larger size will better support

your material, whether holding

inside or out.
