The back of the machine. Incidentally
the second motor is used to drive the
spindle at a single 3000 rpm speed. It
is cheaper and more efficient to do it
this way than trying to use multiple
pulleys get a 100 to 3000 rpm speed
range. When this speed is needed for
a grinder or chop saw, the spindle
pulley is replaced with a smaller one
that is slightly larger than the motor
