Sanding Tips; Choosing Sandpaper - Grizzly G0449 Owner's Manual

Sanding Tips

•
Replace the sandpaper with a higher grit to
achieve a finer finish.
• Raise the table with a maximum of
the height handle until the workpiece is the
desired thickness.
• Reduce snipe when sanding more than one
board of the same thickness by feeding them
into the sander with the front end of the sec-
ond board touching the back end of the first
board.
• Feed boards into the sander at different
points on the conveyor to maximize sand-
paper life and prevent uneven conveyor belt
wear.
• DO NOT sand boards less than 9" long
or less than / " to prevent damage to the

workpiece and the drum sander.
• Extend the life of the sandpaper by regularly
using a PRO-STICK® sanding pad (Page
30).
• When sanding workpieces with irregular sur-
faces, such as cabinet doors, take very light
sanding passes to prevent gouges. When
the drum moves from sanding a wide surface
to sanding a narrow surface, the load on
the motor will be reduced, and the drum will
speed up, causing a gouge.
• DO NOT edge sand boards. This can cause
boards to kickback, causing serious personal
injury. Edge sanding boards also can cause
damage to the conveyor belt and sandpaper.
• When sanding workpieces with a bow or
crown, place the high point up (prevents the
workpiece from rocking) and take very light
passes.

• Feed the workpiece at an angle to maximize
stock removal and sandpaper effectiveness,
but feed the workpiece straight to reduce
sandpaper grit scratches for the finish pass-
es.

Choosing Sandpaper

There are many types of sanding belts to choose
from. We recommend Aluminum Oxide for gen-
eral workshop environments. Below is a chart
that groups abrasives into different classes, and
shows which grits fall into each class.
Grit
36
60
80–100
120–180 Fine
The general rule of thumb is to sand a workpiece
with progressively higher grit numbers, with no
one grit increase of more than 50. Avoid skipping
grits; the larger the grit increase, the harder it will
be to remove the scratches from the previous
grit.
The Model G0449/G0450 allows you to place
a different grit sandpaper on each drum. The
front drum should have a coarser grit than the
rear. Usually this translates into combinations
of successive group types. A common selection
for stock that is planed before being sanded is a
100/150 grit combination.
Ultimately, the type of wood you use and your
stage of finish will determine the best grit types to
install on your sander.
