Other Techniques and Procedures
Filling Cracks and Gaps
Checks and shakes can develop and be found
while turning a piece of wood. Sometimes, it is
necessary to use adhesives and fillers to fill the
cracks to strengthen a workpiece. Make sure the
adhesive is completely cured inside and out
before resuming the work.
Sanding
Sanding removes the toolmarks and can fix
minor blemishes on the workpiece. Before
sanding, remove the tool rest and banjo so there
is no risk of getting the hand trap between the
workpiece and the tool rest. NEVER wrap the
sandpaper around the workpiece to avoid
entanglement risk.
Reduce the lathe speed and use light pressure
when sanding
˙ . Doing so avoids heat build-up
that can damage the workpiece and the
sandpaper. Remove dust and dirt from the
sandpaper to maximize the effectiveness of the
abrasive surface.
Keep moving the sandpaper to avoid grooves
from forming. When switching to a finer grit,
change the sanding direction by 90 degrees to
remove the scratch marks from the previous grit.
Running the lathe in reverse sometimes helps to
remove the scratch marks created by sandpaper.
If a workpiece is mounted on a threaded
accessory, it must be locked on the spindle with
set screws. The faceplate included with the lathe
has two set screws for this purpose.
WARNING
Reduce speed and use extra caution when
running the lathe in reverse with threaded
accessory mounted. Ensure the threaded
accessory is mounted on the spindle with
fasteners, or the accessory can dislodge
from the spindle during the operation. Such
accidents can cause serious injuries or
death.
Only use the reverse spindle direction when
sanding an outboard-turning workpiece.
Otherwise, the workpiece can dislodge from
the spindle if the faceplate set screw cannot
withstand the torque from the operation.
