Shop Safety Rules

Your workshop is only as safe as you make it. Take responsibility for the safety of those
who use or visit it. This list of rules is by no means complete, so remember that common
sense is a must.

Smithy strongly discourages the use of casters or wheels on metal-working machine
benches. The weight of the machine could result in the bench tipping while being moved.
Once the machine is mounted, consider your workbench to be permanent. If you must
move the machine, first remove it from the bench

1. Read this manual thoroughly before operating your machine. Don’t try to do
more than you or your machine can handle. Understand the hazards of operating a
machine tool. I

n particular

, remember never to change speeds or setups until the machine

is completely stopped and nev

er operate it without first rolling up your sleeves.

2. Wear proper clothing. Avoid loose-fi

tting clothes, gloves, neckties, or jewelry that
could get caught in moving parts. If you have long hair, tie it up or otherwise keep it from
getting into the machine. Always wear non-slip footwear.

3. Protect yourself. Use ANSI approved safety glasses, goggles, or a face shield at all
times. Use safety glasses designed for machinery operation; regular glasses will not do.
Have extras available for visitors. Know when to wear a face mask or earplugs as well.

4.

Keep your work area clean and organized.

Clut

tered work areas and benches

invite accidents. Have a place for everything and put everything in its place.

5. Childproof your work area and keep children away from the machine while
it is in use. Childproof your shop with padlocks, master switches, and starter keys or

stor

e the machine wher

e chi

ldr

en do not ha

ve access to it.

6. Never operate your machine under the influence of drugs and alcohol.

7. Keep track of tools. Remove adjusting keys and wrenches from the machine before

operating. A chuck key or misplaced Allen wrench can be a safety hazard.

8.

Avoid accidental starts. Turn the switch to the

OFF posi

tion before plugging in the

machine. Turn the speed dial to zero before starting your machine.

9. Ground your machine. The machine has a three-conductor cord and three-prong,
gr

ounding-t

ype plug. Nev

er connect the power supply without proper grounding

10. Keep your mind on your work. By paying attention to what you are doing and
avoiding distractions you will spend many safe, enjoyable hours in your workshop.

11. Never leave your machine running unattended.

WARNING

Machine Safety Rules

1. Stop the machine before servicing. Stop the machine before making changes,
removing debris, or measuring your work.

2. Don’t over reach. Don’t reach over the machine when it’s operating. Keep your hands
out of the way.

3. Turn the switch OFF. Turn the switch to off before plugging in the machine. Turn
the speed dial to zero before starting your machine.

4. Use proper tooling. Use only recommended accessories and understand how they
should be used before trying them out. Don’t try to make a tool into something it isn’t or
attempt to use a tool in inappropriate ways. Remember to always use the proper tooling
for the material you are cutting. Reference a general machining guide such as Machinist
Ready Reference for recommended tooling for your material.

5.

Secure your work.

Before starting y

our machine, be certain that your workpiece is

properly and securely mounted. Flying metal is dangerous!

6. Do not run you machine beyond its limits of travel. Befor

e starting your

pr

oject, ensure that your work area does not go beyond the limits of travel on your
machine. Going beyond the limits of travel will cause serious damage to your machine
which wi

ll not be covered by your warranty.

7. Run your machine at recommended spindle speeds and feed rates. Always
cut at the r

ecommended speed and feed rates for the type of metal that you are cutting
for optimum performance. Do not begin your cut until the machine has reached the full
and proper speed.

8.

Do not change the direction of the spindle rotation or leadscrew rotation

while your machine is running.

Changing the rotation direction of the spindle or

leadscrew while your machine is running could cause serious damage to your machine.

9. Do not stop the spindle by hand. Always use your on/off switch to stop the spin­dle from rotating.

10. Do not clear chips by hand. Metal chips are very sharp and can easily cut your
hand. Use a brush to clear chips.

11. Protect bed ways. When removing or installing tooling from your lathe spindle,
place a piece of wood or other material across the bed to protect the ways from being
damaged if the tooling is dropped.

12.

Keep your machine maintained.

Overview

It is a good idea to take inventory of the parts of your machine soon after it is
unpacked. By doing so, you can quickly determine if any parts are missing. In addition,
should you find it necessary to return the machine to Smithy for any reason, the
inventory will ensure that all the parts you received have been returned.

A third reason to perform an inventory is to become familiar with the names of all of
the parts of your Smithy machine. To aid with this, the following parts lists have
individual photos of the items listed.

Millhead Components & Functions

The photos below show the front and back of the millhead of the Smithy Granite machine.
The millhead holds the tooling necessary to perform milling and drilling operations. The
following section identifies the components and functions of the millhead.

A. Spindle Cover - The spindle cover protects the spindle from dust and debris. It also
protects the operator from injury. The spindle cover should be in place whenever the
machine is in operation. The drawbar is located under the spindle cover.

B. Millhead Cover - The Mi

l

lhead co

v

er pr

otects the belt and pulleys of the millhead.

The co

v

er should always be in place when the machine is in operation.

C. Quill Lock - The quill lock locks the mill/drill quill in place during a horizontal milling
operation or while changing tools.

D. Mill/Drill Spindle - The mi

l

l dri

l

l spindle is an R-8 taper. It holds and rotates the the

tool

ing used during milling and drilling operation. The spindle also moves in and out of

the millhead quill. The quill is an internal part which is not seen in this picture.

E. Drill Press Handles - The drill press handles move the quill in and out of the mill
head during a dri

l

l

ing operation. Rotating the handles in a clockwise direction moves the

qui

l

l downward, out of the millhead casting.

F. Coarse Feed/Fine Feed Clutch - Pulling out the coarse feed/fine feed clutch knob
engages the drill press handles/coarse feed. Pressing the knob in engages drill/mill fine
feed hand wheel. To easily engage/disengage the clutch, rotate the drill press handles

L-10. Leadscrew Clutch- Is designed to slip to reduce damage to the machine
apron if the carriage is accidentally run into the head of the machine.

Carriage Assembly

The carriage assembly consists of:

• Crossslide table

• Carriage; the lower portion of the table that rides on the bed ways,

• Apron; the portion that hangs from the cross-slide table in front of the
machine.

The carriage moves by hand or by power along the bed ways. Its function is to support
the cutting tool rigidly while in the lathe mode and to secure the workpiece while in the
mill mode. The carriage can be locked into place with the lock found on the back of the
carriage.

The figure to the above right identifies and defines the major components of the carriage
assembly.

A. Cross-SlideTable - The top portion of the carriage assembly. It supports the
compound angle toolpost (not pictured) which holds the lathe cutters and tooling. The
table also supports y

our workpiece when oper

ating the mill. The cross-slide table has four,

7/16” sized t-slots for securing tooling and mounting workpieces.

! NOTICE !

There is a neutral position with this selector. Be sure that it is completey
engaged in either the metric or inch mode before you begin your threading
operation.

B. Cross-Slide Handwheel - This handwheel moves the table toward and away from
the operator along the Y-Axis. Rotating the handwheel clockwise moves the table away
from the operator while moving it counterclockwise moves the table toward the operator.

C. Longitudinal Handwheel - This handwheel is located at the bottom left of the
carriage assembly. Manually rotating the handwheel clockwise will move the carriage
assembly along the X-Axis towards the tailstock end of the machine. Rotating the
handwheel counter clockwise will move the the carriage assembly towards the headstock
end of the machine.One revolution moves the assembly approximately .040”.

NOTE:

This handwheel is for coarse movements only. Use the handwheel at the end of

the leadscrew for fine movement (0.001”)

D. Half-Nut Engagement Lever - This lever closes the half-nut on to the leadscrew.
When the half-nut is engaged, in the down position, the table assembly will be powered
to move right and left along the X-Axis leadscrew.

E. Longitudinal and Lateral Powerfeed Selector - This selector determines whether
the carriage will be power

ed to move along the X-Axis (longitudinal axis) or the Y-Axis
(lateral axis). When the lever is in the upper position the table will move along the Y-Axis.
When moved into the lower position, the table will move along the X-Axis. Center
posi

tion is neutral.

F. Threading Dial - The threading dial is used to coor

dinate consecutive cuts when

cut

ting threads. Restarting each cut from the same point on the dial ensures that each

cut follows the same path, leading to accurately machined threads.

G. Saddle - The saddle supports the cr

oss-sl

ide table and mo

v

es along the X

-

Axis of the

machine.

H. Apron - The apron houses the gear mechanism for the X and Y-Axis powerfeed.
