FACEPLATE & CHUCK TURNINGS
PLANNING THE WORK
Make a layout first, to provide a visual pattern to follow
while working the turning Patterns can be laid out in the
same manner as spindle patterns -- or templates can be
made which can be held against the work for visual
comparison. Circles to locate the various critical points (at
which the contours of the faceplate take distinct form) can
be quickly scribed on the rotating work by using the
dividers.
PLANNING VARIOUS CUTS
The circumference of afaceplate t urning is roughed-off and
finished in the same manner that a spindle is worked,
Practically all of the balance of the operations, however, are
done by using scraping methods. A few of the standard
contours which must often be turned are illustrated in the
accompanying sketch -- which also shows the proper
chisels for shaping these contours. Any roughing-out to
depth that must be done is generally accomplished with the
gouge held in the scraping position,
DEEP RECESSES
The first step is to remove as much wood as possible by
boring into the center with the largest wood bit available
This can be accomplished as illustrated. Be careful to
measure in advance the depth to which drill can be allowed
to go,
BORING TO DEPTH
Now remove the buik of the waste (to rough-out the desired
recess) by scraping w_ th the roundnose chisel or the gouge
Remove up Towithin 1 iSdn. of finished size in this manner.
Finish off the inside circumference by scraping with the
spear-point chisel or skew, Smooth the bottom of the recess
by scraping it fiat with the ftatnose chisel.
Proper support must be provided at all times for the
scraping chisels Severat tool rest positions are shown in
the accompanying illustrations. Always endeavor to position
the part of the rest that supports the tool as close to the
working surface as possible.
The depth and squareness of the sides of the recess can be
quickly checked by holding one of the straight sided chisels
and a combination square as shown_
