Few will argue that
the router is one of the handiest, most versatile power tools in the woodworking
shop. With it, you can edge, shape, dado, groove, mortise, cut or drill
all types of project components with speed, precision and super-smooth
results.
However, because
of its high operating speeds and horsepower (most routers run at between
18,000 and 25,000 rpm's and offer between 1hp and 3hp of brute power),
failure to follow proper safety procedures can make the router one of
the most dangerous tools in the shop. By following these rules for router
safety, you should have no problems:
Getting Started
- Always unplug
the router before installing or changing router bits.
- Inspect all bits
carefully prior to installation:
- If it is a
carbide-tipped it, be sure all tips are firmly secured to the bit
shank. A loose tip can fly off, causing serious injury.
- If the bit
has a bearing pilot, be certain the bearing screw is tight.
- Be certain
your bit is sharp (and clean) prior to use. Dull or pitch-covered
bits require excessive cutting effort, which could result in injury.
Pitch can be removed with sawblade
cleaner, but be sure to remove or cover bearing pilots prior
to cleaning as these cleaners can ruin bearings.
- When installing
a bit, drop it all the way into the router's collet, then back it out
about 1/16" to 1/8" to avoid transferring the heat generated by the
bit directly to your router's motor armature. Be sure the collet is
tightened adequately.
- Rotate the installed
bit by hand to be certain it doesn't hit tables, fences, guards, holding
fixtures, workpieces or other items when the power is initially turned
on.
- Be certain the
router motor switch is turned to the OFF position
before plugging the router into an electrical outlet.
- Have a firm grip
on the router before turning it on. Remember, you're holding between
1hp and 3hp of power in your hands. When you turn on the power, the
torque of the motor will try to pull the router out of your hands. Be
aware of this and be prepared.
- If you're using
a router table, be certain the table is securely clamped to the benchtop
or its support legs before starting work.
The Shop Environment
- Have adequate
lighting in the shop. Due to its potential for personal injury, the
router is one tool you don't want to be using in the dark.
- Be sure your shop
is clean. Excessive sawdust on the floor, for example, can jeopardize
your footing, which can lead to injury.
- Use adequate dust
collection. The router is, by far, one of the messiest tools in the
shop. Its high operating speeds will throw chips and sawdust far and
wide.
- NEVER operate
routers (or other power tools) while standing on a wet floor.
Use Safety Devices
- When working with
a router table set-up, always use a push
stick or push block to move the workpiece past the cutter.
- Always wear proper
ear and eye
protection when working with a router. Routers create an extremely
loud, high-pitched noise during operation that could permanently damage
your hearing. And, since they're notorious for throwing chips
and dust, eye protection is also a MUST. If you're planning to
do a lot of routing...or will be working with potentially toxic woods
such as certain exotics or treated lumbers...a respirator is also highly
recommended.
- When routing an
irregular-shaped workpiece with a piloted bit on a router table, always
use a Starter Pin to help you ease your workpiece into the rotating
bit without snagging.
Holding The Workpiece
- Whenever possible,
always clamp your workpiece firmly to a benchtop or other surface before
working on it with a hand-held router.
- If your using
a hand-held router on a workpiece that's too small to grip in a vise
or with a clamp, use a non-slip
router mat to hold it while you make your cuts.
- If you're using
a router table and your workpiece is too small to grip safely during
an operation, use double-stick
tape or a dollop of hot-melt glue to mount it to a larger piece
of scrap stock, giving you added control.
- When working with
a router table, use a featherboard
to hold your workpiece firmly against the router fence during operation.
Making the cut
- Never take too
much of a cut in a single pass. For maximum safety (and smoother cuts)
take multiple light passes, instead.
- Whenever possible,
feed your router into the workpiece, against the rotation of
the cutter. In those instances when this is not possible and you must
make a climb-cut (with the rotation of the cutter), it
is more important than ever that you take multiple light passes instead
of a single heavy one.
- Feed the router
(or workpiece, in the case of a router table operation) at a slow, steady
pace:
- Feeding too
slowly or dwelling during the cut will overheat the bit, causing
it to lose its temper...and burn the workpiece, as well.
- Feeding too
rapidly will produce a rough cut.
By following these
simple precautions, your work with this highly versatile tool will be
safer...and your results will surely be improved.
