Fig 9
The spur drive centre locks into the
spindle taper and can be removed
with the knockout rod.
Mount the centred workpiece between
the spur drive centre and the tailstock
mounted live centre.
Turn the tailstock hand wheel until the
live centre well penetrates the
workpiece. Reverse the hand wheel by
one quarter turn and lock the tailstock
spindle.
Fig 10
Turn the workpiece by hand to see if it
rests securely between centres and
can be rotated freely (Fig 10).
Fig 11
For turning between centres the tool
rest is set appr. 3mm higher than
centre line (Fig 11 and 12).

6.5 Bowl turning
Turn outside of bowl between centres.
Turn a short tenon the size of the hole
in the faceplate (A, Fig 13). This will
allow centring the workpiece.
Fig 13
Mount the workpiece (A, Fig 14)
directly to the face plate using 4 wood
screws (C) from the back. Be careful
to use screws short enough not to
interfere with the cutting process but
long enough to hold the workpiece
securely to the face plate.
If screw mounting is not allowed at all,
the work may be glued to a backing
block (D) 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.
Mount the face plate with the
workpiece already attached onto the
spindle nose thread and hand tighten.
Move tailstock away, remove centre
from tailstock to prevent injury.
Turn the workpiece by hand to see if it
rests securely and can be rotated
freely.

Fig 14
For face plate turning the tool rest is
set slightly lower than centreline.
Caution:
Cut with your chisel on the left side of
the turning centre only.
Use left hand to control cutting edge
of gouge, while right hand swings tool
handle around toward your body (Fig
15).
Fig 15
Try to make one, very light continuous
movement from the rim to the bottom
of the bowl to ensure a clean,
sweeping curve through the
workpiece.
Move tool support to the exterior to re-
define bottom of bowl.
6.6 Sanding and Finishing
Remove the toolrest and begin with a
fine grit sandpaper (120 grit) and
progress through each grit, using only
light pressure.
Use power sanding techniques to
avoid concentric sanding marks.
Finish sanding with 220 grit.
Apply first coat of finish. Allow to dry
before sanding again with 320 or 400
grit sandpaper.
Turn lathe back on and make a
separation cut through the base. Stop
at about dia. 80mm and use a fine
tooth saw to separate the bowl from
the waste.
