Sanding
and finishing a turning are much easier done on the lathe
than removing it and finishing it by hand. Warning: Before
you start, remove all lathe duplicator components. Caution:
Lay a cloth over the way tubes to catch grit and finish.
For sanding,
use quarter sheets of sandpaper folded into thirds. This gives
you a rigid piece, yet it will bend to fit the shape of the
turning and the thickness helps protect your fingers from
heat build-up (Figure
13-30). Warning: Never wrap sandpaper, steel wool or
a rag around the turning and never use a rag with frayed edges.
They could easily pull your fingers into the workpiece.
Turn the
Mark V on and set the speed dial to the correct speed. Begin
working with new 100-grit paper and light pressure. Then switch
to used 100-grit paper. Finish sanding with new and used 150-grit
paper. For open grain woods, wet the surface to raise the
grain between sandpaper changes. Allow the water to dry before
sanding.
For a
smoother surface and reduced sanding time, dismount the spindle,
turn it end-for-end and sand in the opposite direction. Warning:
When remounting the stock, be sure to put enough pressure
on the quill to engage both the drive and cup centers. You
can reverse the rotation of a faceplate turning by mounting
the faceplate on the upper auxiliary spindle.
For finishing,
use avery low speed and prepare a natural oil finish with
the stain mixed in. Polyurethane is not recommended because
it will dry too quickly. Mask any areas to be glued later.
Soak a
rag and a piece of fine, slightly used wet/dry sandpaper in
the finish. Use the rag to apply the finish to the turning.
Then sand. Repeat, adding more finish until a mixture of finish
and sanding dust covers the entire turning. Rub this paste
with your hands and let it set for a minute or two or until
it becomes sticky. Then buff the turn-ing and let it dry.
Apply additional coats of finish, but do not sand.
