Sherline Products 2000 Installation Instructions

With the introduction of a new product like the Model 2000
mill, it is impossible to anticipate all the uses and setups our
customers will attempt with it. After several months of
feedback, we noticed several areas where customers had
suggested a need for greater clearance or capacity. Some
users noted that lowering the column all the way down
without the column spacer block in place would sometimes
cause the bottom of the rotary attachment to hit the mill vise.
Also, when using small end mills, the column could not be
lowered enough to get the cutter lower than the table surface
for milling the side of a part even with the column extension
removed. The enclosed upgrade eliminates these problems
by allowing the column saddle to be lowered an additional
1.6".
The column saddle lock upgrade provides a superior method
of preventing saddle movement by locking the saddle nut
against the leadscrew. This is much more positive than the
existing friction saddle lock. We have looked for a way to
produce this for years, but it required finding a way to start
a thread in exactly the same place each time so that the
locking movement could be confined to a limited quadrant.
A new piece of equipment in our factory now makes it
possible to control this accurately, so the lock will be added
to all production mills from now on. Upgrade kits will be
available for all older Sherline mills. For purchasers of the
"top-of-the-line" Model 2000, we have included the locking
lever upgrade at no charge.
If you have been using your mill and have not encountered
any problems along these lines, it is not necessary to install
the upgrades at this time. If you do run into a problem where
you need to lower the saddle more than it will currently go,
you can always install it at that time. However, you will
probably find the new column locking lever to be far
superior to the old friction lock, and as long as your are going
to the trouble to replace it, you might as well install the whole
upgrade at the same time.
If you do not wish to install these upgrades yourself, we will
be glad to do it for you for a $15.00 handling fee. You must
pay the cost of shipping the unit to us, and we will pay for
return shipping. Just return your column and saddle unit (not
the whole mill) along with the upgrade package components.
We will install the kit and return the column/saddle to you.
We feel that most of our customers will prefer to do the job
themselves as for most people it is easier than packaging the
column for shipping.
Lowering the saddle makes it easier to work close to the
table. The trade-off that always occurs with any engineering
compromise is that movement at the top of the travel is
limited by the same amount as is gained at the bottom.
Certain tall setups that involve multiple accessories can
stack up to a height that may require more clearance at the
top end. You will probably find that with the upgrade in
place you will operate the mill with the column spacer block
in place most of the time. To achieve more height than that
spacer can provide you have a choice of either purchasing a
second column spacer block or removing the saddle extension
for jobs that require the additional height.
1. Remove the headstock/motor/speed control unit from the
saddle pin.
2. Remove the four socket head cap screws that hold the
column bed to the rotary attachment.
3. Remove the four socket head cap screws that hold the
moveable clamp disk to the arm mount. Index the moveable
clamp disk 180° so the column bed hole pattern is closer to
the bottom and reinstall the four socket head cap screws.
