COMPOUND SLIDE
The tool is moved along the workpiece by the motion of the apron and its compo-
nents. The apron may be power-driven by the lead screw, or may be moved by hand
using the handwheels.
The Saddle Handwheel (AA) may be used to move
the apron with its attached tool post and tools along
the rotating axis of the workpiece. This is used to
make longitudinal cuts.
The Cross Slide Handwheel (Z) is used to move
the tool post horizontally across the axis of the
workpiece. This motion is used to make face cuts
at a 90 degree angle to the longitudinal axis of the
workpiece.
Cuts made at any angle other than 90 degrees to
the axis are accomplished by using the Compound
Slide Handwheel (N).
To use the compound slide, loosen the bolt holding it in place on the cross-slide, rotate
it into the desired position, then retighten the bolt.
The cutting tool can be moved into the workpiece by operating the handwheel.
CHUCK AND FACEPLATE
This lathe may be operated using either
chuck or faceplate to hold the workpiece.
Chucks and faceplates are mounted on the
arbor shaft using a threaded connection.
Open the gear box, and using a suitable
wrench, hold back the arbor shaft to prevent
it from turning. Grip the chuck or faceplate,
and rotate it in a counter-clockwise direction
to unthread it from the arbor shaft.
When re-installing a chuck or faceplate, be
sure to put light grease on the threaded end
of the arbor shaft to ease installation and
removal of the chuck or faceplate.
You are provided with both three and four
jaw chucks. Each may be used to hold
workpieces by clamping from the outside,
or by expanding on the inside of tubes and hollow pieces. To tighten the jaws, rotate
any of the internal hex head bolts in the side of the chuck with an appropriate size hex
wrench. Chucks are self centering, and will align concentric workpieces with the axis
of rotation of the arbor shaft.
Faceplates are used typically to hold larger or non-round pieces. Work pieces may be
attached to the faceplate by a variety of methods including clamps, bolts and screws.
It is critical that the centerpoint of the workpiece be exactly aligned with the center of
rotation of the arbor shaft for accurate turning.
