|  FILING MACHINE (MLA-18)
The MLA-18 filing machine, a distinct machine tool in its own
right, is a modern version of the traditional bench filer.
Nominally, it is a machine for "Type A" files, but many other files
up to 1/4 wide or 1/4 inch diameter can be adapted, which have straight
sides (i.e. are "blunt" and not tapered). Any such file can be cut
to the right length and mounted. The file is operated with a Scotch
yoke and has a one inch stroke. The cutting stroke is downward. This
type of filing machine is capable of very precise work, and of
removing metal at a rapid rate. Due to the speed at which the file
operates and the light work pressure required, the files do not clog,
or "pin," and last a long time. You will find using the filing
machine a totally different experience from hand filing. Many kinds
of intricate work can be done with it to a surprising degree of
accuracy. It is ideal for precision model making and toolmaking.
The filing machine measures 8 1/2 inches high from the
mounting base to the work table. The work table is 7 inches in
diameter and can be adjusted for angular filing. The filer can be
operated with practically any 1725 R.P.M., 1/4 H.P. motor, and probably
even motors of less horse power.
The filer can be mounted on a board with the motor for portable use or permanently on a bench.
The minimum requirement for making the filing machine is a
lathe of nine inch or greater swing. If a milling machine is
unavailable, it is recommended that the lathe be equipped with a "T"
slot cross slide for some set ups. A drill press may also prove
handy. Although the filer is fairly large, it is easy to make. The
operating mechanism is not complex and requires very little precision
machining.
The basic kit for making the filing machine consists of four
iron castings: a body casting; table casting; back plate casting;
and yoke casting. The body casting is cored for the operating
mechanism, which is designed to run in an oil bath. The basic kit
also includes four large drawing sheets (18 by 24 inches) showing
components full size, as well as machining and operating
instructions, including a sheet describing how to make "Type A" files
from other kinds of files.
Optional items include a five inch diameter cast iron pulley blank for flat belt drive, bearing
material consisting of two pieces of continuous cast bronze 4 1/4 ins.
long by 1 1/4 ins. and 1 in. diameter, and a hardware packet. Those items
are offered as options, since many machinists already have them on hand.
An ordinary hardware store pulley can also be used, as can other suitable
material for the bearing sleeves. The hardware packet is supplied as an
option to eliminate the need of having to buy items elsewhere in greater
quantity than required. The hardware packet contains all twenty required
screws (except for the pulley), a Woodruff key, and a 1/16 in. spring
dowel pin.
Other materials required for making the filing machine are mostly
common flat and bar stock. The machining instructions list a
supplier that can furnish exactly the material you need, in the quantity
you need at a modest cost, for that not at hand.

USPS Shipping. To compute Shipping Cost "online",
first add the weight of the optional items, if any, to the weight of
the basic filer kit. (For instance, basic filer kit plus optional pulley
blank and bearing material, 30 lbs. + 5 lbs. +2 lbs.=37 lbs.) Go to the
USPS website and click on"Calculate Price". Enter the zip code 16868 in
the "from" box and your zip code in the "to" box. Scroll down and
select "package". Enter the package weight in pounds and ounces, as
computed in the example above. Then click on "continue". At the schedule
of shipping options select "Priority Mail Options" for the shipping
rate. Note, however, that the "Flat Rate" options cannot be
selected for shipping the filer kit. For some shipments over longer
distances a "Retail Ground" option is available at a lower cost. To
check whether "Retail Ground" is available, at the schedule of shipping
options click on "Other Options". Or inquire. On inquiry, shipping
without prearranged shipping instructions, the lowest rate will be
computed. USPS shipping will be assumed unless otherwise requested.
To compute shipping cost to Canada and overseas "online",
calculate the total weight of the shipment by adding the weight of
optional items, if any, to the weight of the basic kist, as above. At
the USPS website, after clicking on "Calculate Price", select your
country from the list at the top of the page. Enter the item value in
the box. Scroll down and select "Package" from the list. Enter the
weight of the package in pounds and ounces. Then click on "continue".
Select "Priority Mail International Options" for shipping rate. Or
inquire.
FedEx Shipping. To compute FedEx shipping "online",
go to FedEx website and click on "FedEx-Official Site". Go to "Get a
Quick Rate". In the "from" box enter "Pine Grove Mills, PA", and in the
"to" box your town or city and state. Click on "next". At "Pricing
Options" click on "FedEx Standard Rate". In the box enter the weight of
shipment in lbs. Click on "next". Click on "get rate" and select from
the shipping options. Or inquire. Note: an option is reserved for adding
a $4.00 surcharge for FedEx shipping for transport of the package to the FedEx terminal.
Credit will be automatically calculated for double packed orders shipped USPS and FedEx.
Pennsylvania residents please add 6% sales tax.
If you have already ordered the drawing set with instructions and
want the casting set sent without drawings, deduct $8.00 ($2.00 per drawing sheet) from the price of the kit.
Please make check payable to Metal Lathe Accessories, Box
88, Pine Grove Mills, Pa. 16868. Payment by check for Canadian and overseas
orders must be by International or Postal Money Order in U.S. dollars.
