W1681 Buffing Assembly
SETUP
The Shop Fox
®
W1681 does not come with a motor or elec-
trical package. We recommend using a 1725 RPM,
1
3 H.P.
or larger motor.
Always follow the motor manufacturer's electrical require-
ments for the motor that you install.
Choosing a Motor
The buffing assembly comes with a three step arbor pul-
ley. The three progressive diameters are 2", 3" and 4". We
recommend using a 1" motor shaft pulley and a 1725 RPM
motor for the easiest set up of buffing wheel speeds.
The arbor should never rotate faster than 1725 RPM. When
using a 2" pulley on a 1725 RPM motor, in conjunction with
the 2" step on the arbor pulley, you will achieve a buffing
wheel speed of 1725 RPM. As you move the V-belt to pro-
gressively larger pulley steps, the buffing wheel RPM will
drop. Never use a pulley configuration that uses a motor
pulley that is larger in diameter than the arbor pulley. See
the diagram in Figure 1.
Configuring Pulleys
Never use a pulley configuration that
uses a motor pulley that is larger
in diameter than the arbor pulley.
This will result in an arbor RPM that
is greater than 1725 RPM. An arbor
RPM greater than 1725 RPM is not
recommended.
