Note to Parents
There’s something about a new
hammer in a child’s hand that
brings a grin from ear to ear. But
before we start swinging, some
safety tips are in order. Never use
a hammer without safety glasses.
Chips of wood or a missed hit nail
can go flying faster than anyone
can react. Now is a good time to
instill in your child the importance
of safety in the woodshop.
Leverage-The
increased force
resulting from the use
of a lever (or the
handleof the hammer
in our case).
Momentum-The
force of a moving
object.
Lesson 3
It’s Hammer Time!
Ahammerisasimpletool. It’susedtostrikethingssuchasnails,nail

back out again. But as with all tools there is a correct way to use a
hammer so you’ll get the most out of it. Before we get started keep in
mind when using a hammer always put on your safety glasses first.
Using the hammer
At first, most people want to choke-up on the handle,
(move your hand closer to the head of the hammer),
to get more control. However, by doing this you give
up most of yourmomentum, which is the force that
drives the nail into the wood. Another way to look at
it is that the arc that you swing the hammer in is
much smaller if you hold the hammer towards the
head, which takes away your power. If you hold the
hammer’s handle towards the end you increase your arc and
thereby increase your momentum. By doing this you combine
the weight of the hammer, with the swinging of your arm and
wrist to pound the nail home.
The second operation of your hammer is to pull nails out. At the

and tapers down, as it gets closer to the head. This is to wedge the nail
head in tight so it doesn’t slip out. When pulling a nail out place a block
of wood under the head of the hammer to gainleverageand to
keep from damaging your work surface. With the hammer
upside down and the nail wedged between the claw pull
back on the handle towards your chest.
