is a frame of mind, and should be an important part of everything
we use or do. You can have an accident when driving, trip when climbing
stairs, fall when pruning a tree, or slip in the tub. We are surrounded
by potential hazards.
people who don't become victims are those who accept the possibilities
and prepare for them. Woodworking safety requires good common sense.
woodworkers have been known to neglect to use guards and will ignore
correct procedures, feeling that they are knowledgeable enough to
be immune. Accident statistics are comprised of these people, and
it is interesting to note that included are more professionals than
amateurs. Safe woodworking is not a matter of experience or expertise,
or the sophistication of the tool you are using. Safety rules should
be studied and followed, not ignored.

Factors Built into the System
Warning: For your safety, always read, understand and follow
the procedures in the Owners Manual and use the guards and safety
equipment that came with your machines.
Shopsmith Woodworking System has many built-in safety features,
but the effectiveness of these features depends on you.
shop accidents happen on unguarded power machines. Therefore, it
is important to keep guards in working order and to always keep
them mounted on the machine during operations. Guards, like the
upper saw guard shown in Figure 1-20, are designed to prevent kickback
and to help keep your hands out of the danger zone.
Accessories and Devices--Accessories and devices such as the
miter gauge with safety grip, fixtures and extensions help to keep
your hands away from the blade, cutter or disc. The miter gauge
with safety grip holds the stock securely and safely during the
operation (Figure 1-21). Rip fence and miter gauge extensions, and
fixtures that you can make help to support and guide the stock (Figure
Safety Kit--The safety kit (Figure 1-23) contains a push stick,
push block, feather board and fence straddler.These devices either
help guide, hold and control the stock safely during operations
on the Mark V or Major Accessories.
push stick (Figure 1-24) is used to guide small to medium sized
stock. Place the foot on top of the stock and hook the heel over
the back edge.
push block (Figure 1-25) is used to hold down and guide the stock.
As you press down, forward, and to the side, the rubber pad grips
the stock. The handle is tilted to help keep your hands out of the
feather board (Figure 1-26) is used to press stock against the rip
fence or the table. Mount the feather board in a table slot, in
the slot of a fence extension, or clamp it to the table. The fingers
must be angled in the same direction that you feed the stock-use
the arrow on top of the feather board as a guide. Position the fingers
so they press against the stock just before it gets to the blade
or cutter, then tighten the locking knobs. To reverse the direction
of the fingers, remove the mounting bar, turn the feather board
over, then replace the bar.
fence straddler (Figure 1-27) is used to hold down and guide small
narrow stock past a blade or cutter. The body rides on the rip fence,
while the heel hooks over the back edge of the stock. To change
the height of the heel, loosen the locking knob. To reverse the
heel, rotate the side 180°. Be sure the lcoking knob is secure before
using the straddler.
V Table Inserts--The Mark V worktable has an opening that is
shaped to receive various table inserts, each of which is designed
to accommodate a particular blade or cutter (Figure 1-28). The purpose
of the insert is to support the stock and to minimize the opening
around the cutting tool. If you're working with very thin stock
that could be drawn down into the opening, make special inserts
like the one shown in Figure 1-29. As you can see, there is no room
for thin material to be pulled beneath the table. Construction details
for the special inserts are found in Chapter 2, "Special Table Inserts."
V Spindles--The main Mark V spindle and the upper auxiliary
spindle which projects at the rear of the power plant are designed
with a "reverse taper" to keep accessories secured. All the accessories
and arbors that mount on the spindles must be positioned so the
locking screw seats firmly against the flat (Figure 1-30). This
is a safety feature that is provided as a precaution against tools
coming off the spindle should the locking screw become loose.
properly mount an accessory, push it all the way on the spindle.
Then use a 5/32" Allen wrench to tighten the setscrew against the
flat of the spindle. To make sure the accessory is securely mounted,
rock the accessory back and forth slightly as you tighten the setscrew
and then again after it is tight, while keeping the spindle from
turning, If the accessory seems to loosen, tighten the setscrew
again until you've removed any 'play.' Warning: During any prolonged
operation, always check the locking screw occasionally to be sure
that normal tool vibration hasn't caused the screw to loosen.
Besides the built-in safety features of the machines, there is other
safety equipment that you'll need to add to your shop.
Ear and Nose Protection--Figure 1-31 shows products that should
be standard equipment in any shop. They don't saw, sand, drill or
plane, but they protect you when doing such operations. Safety glasses,
goggles or a face shield should be worn for all workshop operations.
Ordinary eyeglasses do not provide adequate eye protection.
people feel that a dust mask should only be worn when doing sanding
operations. Actually, sawing, jointing, planing, shaping and routing
can produce dust that is fine enough to accumulate in the lungs--a
potentially harmful situation. Warning: The bonding agents
in some plywoods can irritate the throat and lungs; the dust from
some woods can be toxic causing an allergic reaction or other injury.
Wear a respirator when doing any operation that produces fine particles.
Be sure to clean or replace the filters in the respirator regularly.
you work around power equipment, hearing protectors are just as
important as eye protectors. Warning: High frequencies can
be generated by high-speed motors and even some woodworking operations.
The effects are cumulative; each prolonged exposure can have an
effect that, over the years, may result in a hearing loss.
A good pair of hearing protectors will screen out high frequencies
while still permitting normal conversation.
Collection System--As you work, with your Shopsmith Woodworking
System, you'll find there's another hazard that literally springs
up under your feet if you don't do something about it--sawdust.
like other woodworking clutter, can cause you to lose your footing
and fall into the machinery. It can also be a fire hazard. Tracking
sawdust from your shop into your home can be a nuisance to those
with whom you live. Warning: Breathing sawdust can be a health
hazard. Several medical studies have shown that prolonged exposure
to sawdust may cause impaired breathing. Sawdust may also cause
you physical discomfort, especially if you have emphysema, asthma,
or an allergic reaction.
you work in a shop where the dust in the air can become highly concentrated,
or if your woodworking generates a lot of fine wood dust, wear a
close-fitting dust mask, open a window and use an exhaust fan to
ventilate your shop.
of the most effective ways to protect yourself from the effects
of sawdust and keep your shop clean at the same time is to use a
dust collection system. The hoses from a system connect to the dust
chutes on your power tools. The Shopsmith Dust Collector (Figure
1-32) is an extremely effective dust collection system. It will
give you virtually dust-free woodworking. Refer to Chapter 25 for
Dust Collector information. Pay special attention to Table 25-1,
a listing of toxic woods and possible reactions.

1-1: Speed Dial Conversion Chart for 50 hz Operations
To determine the speed dial setting for 50 hz operations find
the RPM closest to but not exceeding the RPM recommended in
the text. Set the speed dial to the letter given.
The Mark V is equipped with a speed dial that is calibrated by letter
through variable speed ranges (Figure 1-33). Correct speeds are
important for safety and good craftsmanship. The speed setting is
determined by the operation being performed and the material being
processed. Speed dial settings for particular operations are given
throughout the text. When there is doubt about what speed to use,
start with a slow speed and increase it slowly to the point where
the operation is going smoothly. The main and upper auxiliary spindles
turn from 700 RPM to 5200 RPM. The lower auxiliary spindle turns
1.6 times faster than the other two, or between 1120RPM and 8320
The Mark V speed
dial settings with the RPM in parentheses that are given throughout
the text are for 60 hz operations only. Most owners have the 60
hz machines. If you have a 50 hz machine, use Table 1-1 to convert
the RPM for 60 hz operations to the proper speed dial settings for
50 hz operations.
