Turning with A Lathe Chuck
here for a printer friendly version of Tip
Lathe Chucks are the most convenient way to turn bowls, plates
and similar objects. Your workpiece doesn't have to be screwed
solidly to a faceplate. No more screws going through the bottom
of your turning...or gluing scrap blocks to your
blank then screwing them to the faceplate.
save a lot of time and once attached to the Chuck, your turning
may be removed then re-attached again and again...quickly
and with automatic self-centering.
are many different types of Chucks to choose from. Collet
Chucks and Spigot Chucks for externally grasping small to
medium turnings; Three or Four-Jaw Chucks for externally grasping
larger turnings; Expanding Dovetail Chucks that grasp the
inside surfaces of a shallow, dovetail-shaped recess turned
on the bottom of a workpiece; and more.
4-jaw, self-centering variety is the most popular because
it will either grasp the object around its outer circumference
- or expand against its inside edges or against a shallow,
tapered hole that's been turned on the object's bottom.
Oneway Chucks offered by Shopsmith are of the Scrolling variety.
Each features a geared Scroll which moves all four Top Jaws
simultaneously when it's is turned by a geared Key (Talon
& Stronghold) or by twin levers (Original Oneway).
