Sherline 5000 Mill Assembly Instructions

-10-
The mill may be mounted in a similar manner on a 10" x 12"
to 12" x 24" pre-finished shelf board with rubber feet using
10-32 x 1" screws to attach the mill to the board.
REMEMBER: DO NOT LIFT YOUR MACHINE BY THE
MOTOR! Carry the machine by lifting under the base or
by the mounting board.
To keep your Sherline tools clean, soft plastic dust covers
are available. The lathe cover is P/N 4150 for the Model
4000/4100 and 4500/4530 short bed lathes and P/N 4151
for the Model 4400/4410 long bed lathe. A mill dust cover
is available as P/N 5150 for 5000-series mills and P/N 5151
for 2000-series 8-direction mills.

The overall sizes are based on standard
laminated shelf material. You may adjust
them to fit the material available to you.
The mill mounting boards will have to be
cut to length as shelf material is not
normally available in lengths that short.
NOTE: Alignment keys are fitted to each machine. If you
have more than one machine or component that uses an
alignment key, try not to mix them up.
Removing the headstock alignment key permits the
headstock to be mounted in positions other than square.
This allows you to mill parts at an angle or turn tapers on
the lathe. When using the lathe or mill without the alignment
key, keep cutting loads light.
MOUNTING THE LATHE AND MILL TO A BOARD
Mounting the lathe to a board is necessary because of the
narrow base. This keeps the machine from tipping. We
recommend mounting the lathe on a piece of pre-finished
shelf material, which is readily available at most hardware
stores. (See Figure 11 for sizes.) The machine can be
secured to the board using four 10-32 screws with washers
and nuts. Lengths should be 1-1/2" for short bed lathes and
1-7/8" for long bed lathes. Rubber feet should be attached
at each corner on the bottom of the mounting boards. They
are also readily available in hardware stores.
This arrangement gives the machines a stable platform for
operation yet still allows for easy storage. The rubber feet
help minimize the noise and vibration from the motor.
Mounting the tool directly to the workbench can cause
vibration of the bench itself, which acts as a “speaker” and
actually amplifies the motor noise. Bench mounting also
eliminates one of the best features of Sherline
machines...the ability to be easily put away for storage.

RUBBER FEET
mill from one measurement system to the other is possible,
but it takes more than changing the handwheels. The
leadscrews, nuts and inserts must also be changed. A
look at the exploded views of the machines on pages 42
through 44 will show which parts need to be purchased.
(Look for parts that have both a metric and inch version
in the parts listing.) Conversion kits with all the necessary
parts are available. If you are a good mechanic, you can
do the conversion yourself, or you can return your machine
to the factory for conversion.

ADJUSTMENTS
TWO-SPEED PULLEY

B
FIGURE 12—The two pulley positions. Position A is the
conventional setting, position B offers more torque at
low RPM when turning large diameter parts.
NORMAL BELT POSITION
HIGH TORQUE, LOW RPM POSITION
The normal pulley position, which is placing the belt on the
larger motor pulley and smaller headstock pulley, will suffice
for most of your machining work. Moving the belt to the
other position (smaller motor pulley, larger headstock pulley)
will provide additional torque at lower RPM. It is particularly
useful when turning larger diameter parts with the optional
riser block in place. To change the pulley position, remove
the speed control hold-down screw and pivot the speed
control housing up out of the way. Remove the mounting
plate from its position on the rails of the two halves of the
