Sanding Belts
As sanding drums are used, the sandpaper can
quickly become "loaded" with sawdust. If not
removed, this sawdust may harden on the
abrasive surface and can glaze instead of sand
the wood, thus, rendering the sandpaper
useless.
To avoid this condition, routinely clean the
sandpaper with a rubber gum abrasive cleaner
such as the D3003 PRO-STIK

. to extend the life of
the sandpaper.
Discard all worn
sandpaper
because
the grit will fall off
causing deep gouges
in the workpiece. Also
the glue used to hold
the grit to the paper
can rub off onto the
workpiece burning the
workpiece. Contrary to some beliefs, worn
abrasive belts are not the equivalent to the next
finer grit abrasive.
There are many types
of sandpaper you can
use. Aluminum Oxide
is excellent for general
wood shop use. To the
right is a chart that
groups abrasives into
different classes, and
shows which grits fall
into each class.
The Model W1678 allows you to use two different
grit sandpapers at once. The first drum is fitted
with a coarser grit than the second. Usually this
translates into combinations of successive group
types. A common selection for a workpiece that
is planed before it is sanded, is the 100/150 grit
combination.
Overall, the general rule of thumb is to sand a
workpiece with sandpaper that uses progressively
higher grit numbers, with no one grit increase of
more than 50.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types
to install on your sander.
