Delta 46-700 - Faceplate Turning Operations; Mounting Work to Faceplate; Inboard Faceplate Turning Setup

FACEPLATE TURNING
Turnings which cannot be worked between centers must be mounted on a faceplate or other work¬
holding device. The greater part of this type of turning is done with the faceplate mounting, although
there are a number of jobs which require special chucks. All cutting in faceplate work is done
by scraping; any attempt to use a cutting technique on the edge grain of large work will result
in a hogging, gouging cut which may tear the chisel out of your hands. All work should be roughly
band sawed a little oversize to eliminate heavy roughing cuts in turning.
MOUNTING WORK
TO FACEPLATE
Fig. 76 shows direct mounting to the 3” faceplate.
Because it is easy to set up, this mounting should be
used whenever the work permits. Larger pieces can be
held in the same way by using the 6” faceplate. When
normal screw-fastenings interfere, the work can often be
mounted on a backing block, as shown in Fig. 77. When
screws are not permissible at all, the work is glued to the
backing block, fitting a sheet of paper at the joint to allow
later separation without damaging the wood. Some work
can be screwed or nailed from the face side into backing
block. Work less than 3" diameter can be mounted on the
single screw center, as shown in Fig. 78.

INBOARD FACEPLATE TURNING
Fig. 79, illustrates a typical inboard faceplate turning set¬
up. Inboard faceplate turning is used mostly when the
workpiece (A) will rotate freely over the lathe bed, as
shown. The workpiece (A) is mounted to a faceplate and
the faceplate is threaded onto the spindle. Note that the
standard equipment tool rest (B) can be adjusted to turn
the outside diameter of the workpiece.
