drum 

sander allows it to be used for a wide-ranging vari- 
ety of tasks that will boost the return on your 
investment. For example, its capabilities range 
from taking the place of a planer to thickness 
rough stock, all the way to speeding up fine sand- 
ing work often done with slower, dust-generating 
hand sanders.

Learning to use its multiple adjustments and 

controls will allow you to fine-tune the machine 
for maximum results, regardless of the job to be 
done. The best results come from experimenting 
with different abrasive combinations and machine 
adjustments to fit the job at hand. Following is a 
listing of useful tips which can help you improve 
performance of your sander.

Dust Collection. 

When connecting dust collec- 

tors, remember that straight pipe will not restrict 
airflow as much as flexible tubing. Also, Ys and 
elbows will restrict airflow less that Ts. When con- 
necting to the ports of the 37x2, use a larger 
diameter pipe to the machine, and then split to 
4" hoses connected to the ports. An alternative is 
to use separate 4" lines running to the ports; 

do 

not 

use only one 4" line and split it by the 

machine.

Multiple-Piece Sanding Runs. 

When abrasive 

planing (or thickness sanding) a run of similar 
pieces that you want to have the same thickness, it 
is best to determine the thickness of the thinnest 
piece and process all pieces to that same thickness. 
Be aware that the sander will remove cups and 
crowns in the work piece; consider this when mea- 
suring and processing stock to the same thickness.

Sanding Multiple Pieces. 

When sanding multiple 

pieces simultaneously, make sure to stag- ger 
(step) the pieces across the width of the con- 
veyor belt. This provides better contact with the 
tension rollers. Try to only process multiple pieces 
of similar thickness. If there is a significant thick- 
ness difference, the thinner pieces can slip on the 
conveyor belt when they do not contact the 
tension rollers. Also note that pieces thicker than 
3/4" should be longer than the minimum 
normally recommended to prevent tipping of the 
stock (see Specifications). Going to longer pieces 
is especially important when sanding boxes or 
other tall, short or light stock.

Edge Sanding

. When edge sanding, the  sander 

will mimic the opposite edge of the stock which 
is laying on the conveyor belt.

Because of this, it 

is important for the stock edge to have been 
ripped or jointed at the proper angle to the face 
before the sanding process. When edge sanding 
stock that is less than 3/4" wide, or more than 2" 
high, it is good procedure to stack and clamp 
several pieces together to prevent them from 
slipping or tipping on the conveyor belt.

Sanding Imperfect Stock

. When sanding stock 

with a cup or crown, place the crown up. This will 
stabilize the stock to help prevent tipping or rock- 
ing during sanding. (After the crown has been 
removed and the top is flat, turn the stock over 
and sand the opposite side.) To avoid personal 
injury, take special care when sanding stock that is 
twisted, bowed, or otherwise varies in thickness 
from end to end. If possible, support such stock as 
it is being sanded to keep it from slipping or tip- 
ping. Use extra roller stands, help from another 
person, or hand pressure on the stock, to minimize 
potentially hazardous situations.

Face Frames & Raised Panel Doors

. It is very 

important to have the proper abrasive contact 
when doing this type of sanding. If the machine is 
set to take an excessive depth of cut, the result can 
be a gouge or dip as the drum goes from sanding 
the rails at full width to sanding just a few inches 
of width on the stiles. To prevent this, make sure 
that when using abrasives finer than 80 grit the 
drum is in contact with the wood but can still be 
spun by hand. If there is room, angling the stock 
on the conveyor belt can also help. Slowing the 
conveyor feed when coming to a rail in the stock 
can help prevent a dip or gouge.

This allows the abrasive to work the wider width 
with less effort, and to achieve better consistency 
of the finished surface.

Stock Feeding Angle. 

Some pieces, because of 

their dimensions, will need to be fed into the 
machine at a 90° angle (perpendicular to the
