W1681 Buffing Assembly

P
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.
