Operating The Sander
Drum Sander Vs Thicknesser
Drum sanding gradually removes material in increments of 0.8mm or less depending on sanding grit, stock
hardness, stock width, etc. Thicknessing, on the other hand, is for quick, bulk material removal at rates up
to 3mm per pass. If you have used a planer thicknesser to smooth and dimension timber you will quickly
learn to work with the drum sander, but do not over work it.
9
Be patient, let the drum sander do the work: 0.8mm or less per pass for best results.
The most common mistake made with a drum sander is forcing it to remove too much material too fast.
Variables such as sandpaper grit, stock width, wood type, feed rate, and moisture content all influence how
much material can be removed in a single pass.
Double Pass
The maximum sanding width in a single pass is 255mm. When working with
stock up to this width, the drum height lock should be engaged once the drum
height has been set.
It is possible to work with stock up to 510mm wide by making 2 passes.
Firstly, remove the End Plate to make the end of the sander open.
Use a 13mm spanner to remove 2 bolts then remove the locking knob.
Wider stock can now be fed through the drum, with only the first 255mm being
sanded. The stock can then be rotated 180 degrees and fed back into the
sander with the remaining area being sanded to the same depth.
Abrasive Grit Selection
Smoothing wood, or sanding, is the process of making finer and finer scratches until they become so small
they are no longer visible to the human eye.
The grit size of the sandpaper designates the coarseness of the abrasive. The lower the grit number, the
coarser the sandpaper and the larger the scratches made to the surface. Thus 80 grit sandpaper is coarser
(bigger scratches) than 120 grit sandpaper, and 120 grit is coarser than 240 grit, and so on. With coarser
grit papers, such as 80 grit, very aggressive material removal and surface scratching occurs, whereas with
240 grit, very little surface material is removed and a buffed like look begins to appear.
Typically, you begin sanding with a coarse grit and progressively work through finer grits until the desired
finish or thickness is achieved. Choosing which grit to begin sanding with is a subjective judgment based on
your assessment of stock condition (rough, smooth, etc.), thickness, hard/soft wood, and the desired outcome.
Below are some general guidelines regarding sanding grits. Pre-cut wraps in each listed grit size are available.

Drum Height
The height of the drum is raised by turning the handwheel in a clockwise direction. To lower the drum, turn
the handwheel in a counterclockwise direction. The depth of the movement is approximately 0.4mm per 1/4
turn in either direction. One complete turn is 1.6mm. Depth settings can be measured using the height
reading scale. Depth settings used during surface sanding of stock are adjusted by considering several
variables. The hardness of the material, the width of the material being surfaced, and the feed rate selected
are all considered when determining the amount of material to be removed on each pass. Never remove
more than 0.8mm of material in one pass.
Conveyor Feed Rate
The variable feed rate is set to prevent burning and provide a smooth sanded surface on different types
and widths of materials. As a general rule: 1/4 turn or 0.4mm or less is recommended stock removal for
coarser grits and softer woods, while 1/8 of a turn or 0.2mm may be more desirable with harder woods
and/or finer grits. Some experimenting and practice will be required to become familiar with the sanding
performance of your Drum Sander.
When selecting the rate of feed for the material being surfaced:
Wider material - slow the feed rate.
Harder wood - slow the feed rate.
To Begin Sanding
1. With power off, place stock on the feed table and advance the stock to a point so that you can adjust
height of sanding drum to equal thickness of stock at its greatest point.
2. Connect and turn on the dust extractor.
3. Adjust feed rate to match sanding requirements and width of stock.
4. Turn on unit and place stock on the feed conveyor table allowing the feed belt to carry the stock into
and engage the sanding action of the drum. Support long stock as necessary during the feed operation.
Once the sanding operation feed allows, reposition yourself to the out feed side of the machine to accept,
support, and control the board as it exits the Sander. NOTE: Do not apply upward or downward pressure
when supporting and guiding stock through the sander. To do so may induce snipe (sander drum dig-in)
into the sanded stock.
5. Reverse the feed direction of the stock on successive passes, while adjusting the depth of cut using
the height adjustment hand wheel.
11
Sanding Wrap Replacement
The most convenient way to buy sandpaper wraps is to use the precut type which come with the tapered
ends ready to install.
The other option is to buy a roll of 82mm wide sandpaper and cut the tapers yourself.
The template below gives the dimensions for the tapers.
Left Clamp End Right Clamp End
To Change The Sandpaper Wrap
Disconnect from the power supply.
Identify the wider (15mm) end of the
wrap.
Make a fold around 30mm in from the
end.
On the left side of the drum, press the
spring loaded clip up towards the rim of
the drum.
Insert the tip of the wrap through the slot
in the drum and into the teeth of the clip.
Approximately 30mm of material should
be inserted into the clip.
12
Stand in front of the drum and radially
wrap the abrasive material.
Roll the drum away from you, whilst
keeping some tension on the abrasive
wrap and guide it onto the drum.
The edge of the taper should be parallel
to the edge of the drum.
Continue along the length of the drum:
Do not let the sandpaper overlap, it should
be flush or slightly gapped.
On the right hand end of the drum, press
the clip and tensioning device towards the
slot in the drum.
Insert the end of the wrap into the clip
whilst keeping tension on the wound part
of the wrap. When the clip is released it
will grip the wrap and apply tension to it.
The tensioning device will hold tension in
the event the wrap stretches during use.
TIP: The final part can be quite fiddly.
You may find it helpful to place a wedge
of timber into the open end of the drum to
prevent it from rotating whilst inserting
the tail end of the wrap.

Servicing And Maintenance
Conveyor Belt Tracking Adjustment
Occasional adjustment of the conveyor
belt tracking may be required due to belt
stretching. Ideally, the conveyor feed belt
should track in the center of the table.
Adjustment nuts are located on both
sides of the outfeed end of the conveyor.
To adjust, use a 10mm spanner with the
conveyor running at full speed.
If the belt is tracking right, towards the
motor side of the sander:
Tighten the nut on the motor side and
loosen the nut on the floating side.
It may take a few moments to see the
effect happening.
Conveyor Belt Replacement
The conveyor feed belt may need
replacing after normal wear and tear.
Disconnect from the power supply.
Raise the sanding drum to its highest
position.
Remove the End Plate.
Use a 6mm Allen key to loosen 2 bolts on
the right side which secure the table to the
sub frame.
14
Use a 6mm Allen key to completely
remove the 2 bolts on the open side which
secure the table to the sub frame.
Reduce tension on the conveyor feed belt
by rotating both the left and right belt
tracking nuts in a counterclockwise
direction.
Remove the used conveyor belt by
grasping both sides of the belt. Gently lift
the conveyor table as you slide off the
conveyor belt.
If the belt will not move, further reduce the
tension on the feed belt and ensure you
are lifting the table high enough to allow
the feed belt to slide off.
To install the replacement conveyor feed
belt, follow the steps in reverse.
Center the new belt on the table and
evenly tension the belt using the left and
right tracking adjusters.
Remove 2 Bolts
15
Excess Movement in the Floating End
of the Drum
If movement is detected, check the
tightness of the 2 Clamp Bolts.
Adjusted the bolts to allow smooth height
adjustments, while ensuring a tight
enough fit to limit drum deflection.
If the screws are too loose, the drum will
deflect during use, causing an uneven
sanding surface. If the screws are too
tight, sanding drum height adjustments
will be difficult.
To adjust the screws, use a 6mm Hex
Key and 13mm spanner.
Loosen or tighten each bolt, as required,
in 1/8 turn increments to attain the
desired fit and smoothness.
