Installing Abrasives
An 80-grit abrasive strip is already installed on the
drum of your sander. Page 28 offers information on
the types of abrasive and their recommended uses.
Proper attachment of the abrasive strip to the drum
is critical to achieving top performance from your
drum sander. Abrasive strips do not have to be pre-
measured. The end of the roll is first tapered and
attached to the left (outboard) side of the drum.
Then the strip is wrapped around the drum, and the
second taper is made for attachment to the right
(inboard) side of the drum.
Note:
When using JET Ready-To-Wrap
TM
abrasives, not all of the steps below are necessary.
You can use the original abrasive strip mounted to
the drum as a template for cutting your own strips.
1. Mark and cut a taper at one end of the roll as
shown in Figure 9. Because the tapered end
should use all of the left (outboard) slot width,
its end must be trimmed back three inches as
shown.
2. Squeeze the fastener
lever
(Figure 10) on the
outboard end of drum, and insert the tapered
end of the abrasive so that it uses most of the
width of the slot. Release the fastener lever to
securely hold the strip end to the fastener.
3. Begin wrapping the strip around the drum. The
tapered edge of the strip end should follow the
edge of the drum.
4. Continue to wrap the
abrasive
in a spiral
fashion by rotating the drum with one hand and
guiding the strip with the other (Figure 11).
Successive windings of the strip should be
flush with previous windings
without any
overlap.
5. Mark the trailing end of the strip where it
crosses the right (inboard) end of the drum
(Figure 12).
6. Remove
the
abrasive strip
from the drum, and
cut a taper as was done with the starting edge
(see Figure 9).
Note:
The taper on the remaining roll can be
used as the taper for the starting edge of the
next strip to be cut.
7. Rewrap the drum beginning at the left, as
described in steps 2-4.
