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.
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 25).
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 tool rest 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.

Fig 25
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.
Apply additional finish coats and allow to dry before buffing.
7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out after
the machine is protected against accidental starting by
pulling the mains plug.
7.1 Changing speed range
Disconnect the machine from the power source!
Loosen the locking screw and open the belt cover.
Loosen the locking handle (A, Fig 26).
Lift up on the tensioning handle (B) to remove tension from
the poly v-belt.
You can now position the belt in the desired speed range.
Note:
The "High" speed range (0-3200) provides maximum speed,
where as the "Low" speed range (0-1200) will provide
maximum torque.
Lower the tensioning handle so that the weight of the motor
provides the needed tension and tighten the locking handle.
Close and lock the belt cover.
