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

®

15" x 20" cleaning

pad shown in Figure 51. 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.
