Using the Parting Tool
The parting tool is a scraping tool and is simply
pushed into the work piece. A better cutting
action is obtained by starting the cut with the
handle low and gradually raising it as the cut
gets deeper. If the cut is over 3/8" deep, a
clearance cut should be made alongside the first
cut to avoid burning the chisel point.
Face Plate Turning
Work that cannot be turned between centers
must be attached to and turned on a face plate.
All work should be cut slightly oversized prior to
mounting on the face plate to prevent heavy
roughing cuts during turning.
Mount the work piece directly to the face plate
using four wood screws from the back. Be
careful to use screws short enough not to
interfere with the cutting process but long
enough to hold the work piece securely to the
face plate. If screws will interfere with the cutting
process, the work piece can be screwed to a
backing block and the backing block screwed to
the face plate. If screw mounting is not allowed
at all, the work may be glued to a backing block
and the backing block screwed to the face plate.
A piece of paper in the glue joint will prevent
damaging the wood when separated later.
Remove the spur center from the headstock
spindle by inserting the drift pin into the opening
in the headstock and pushing the spur center
out. Mount the face plate with the workpiece
already attached onto the threaded portion of
the spindle and hand tighten. Note: Pieces up to
12" may be turned with the headstock spindle
facing the tailstock (Figure 13). For larger work
pieces, the head stock will have to be turned 90
degrees, the tool rest extension added to the
tool rest, and the tool rest moved out to the bed
extension (Figure 14).
For face plate turning, the tool rest is set
approximately 1/8" from the work piece and
slightly lower than centerline. The chisel must be
held on the left half of the tool rest so that the
rotation of the work piece keeps the chisel
against the tool rest. Attempts at cutting from the
right side of the rest may cause the chisel to be
ripped from the operator's hand.
