Narrator: sure, your mobile
phone will give you the time,

But not nearly as conveniently

Or fashionably
as a wristwatch does.

Watches come in a variety
of materials,

Often combined
with stainless steel.

But one of the more
creative pairings

Is stainless steel with wood.

This company makes wristwatches

Which feature exotic
hardwood accents.

This particular model
is a limited-edition series

Designed for new york
yankees baseball fans.

The blue-painted maple comes
from wooden seats salvaged

From the original
yankee stadium,

Which opened in 1923.

At the watch factory,

A worker first cuts
a strip of wood

Just over a third
of an inch thick,

Then cuts it into blocks

Measuring around
three fourths of an inch

By a third of an inch each.

Manufacturers
will ultimately use

These blocks
to make the wood inlays

In the links
of the watch bracelet.

The worker then cuts
another strip

From a piece of wood,

This one nearly a quarter
of an inch thick.

The worker then cuts this strip

Into nearly 2-by-2-inch squares.

Each one will become
a ring called a bezel

That goes around the watch dial.

Another worker mounts
one square at a time

On a lathe and bores
a hole through the middle.

She mounts several
board squares

Onto a steel mandrill

That attaches to the lathe along
with the bezel template.

As the lathe turns,

A steel roughing gouge
rounds the squares

To the diameter of the template.

She takes one bezel at a time

And cuts it
to the required thickness,

About a tenth of an inch.

She then shaves wood
from the underside

So as not to remove
the historic blue paint on top.

To make the watch case,

Which houses the dial
and movement,

The manufacturers cut
a blank piece

Of extruded stainless steel,

Then place it in
a computer-guided machine.

Under a continuous
shower of lubricant,

The machine's 12 different tools

Take turns shaping the piece
into a watch case.

The first tools bore

A hole in the middle
for the movement

And carve a groove around
the hole for the wood bezel.

The next tools cut
the outside profile of the case

And the lugs for attaching
the watch band.

Then, the final tool drills
holes in the lugs

For the spring-loaded pins

That attach the watch band
to the case.

Another computer-guided machine
makes the watch band

And links out of a bar
of stainless steel.

This machine reduces the bar
and width, carves out the links

And bores holes
for the connecting pins.

A process called ion
plating puts a black finish

On all
the stainless-steel parts.

Then, a worker
assembles two bands

And connects one
to the watch clasp.

Next, he attaches
the watch case window.

It's made of sapphire glass,

A crystal that's
exceptionally durable.

He inserts the self-winding
movement and dial.

The dial is a sheet of brass
with cut-out numbers

And indices over a base.

Coated in luminescent paint,
the watch glows in the dark.

He secures the movement
to the case

With a retaining ring,

Then inserts the crown,
which sets the dial's hands.

The worker screws on
the stainless-steel case back.

The watch's window
of sapphire glass

Allows you to see
the working movement inside.

The case back is engraved

With the name of the
limited-edition collection

And this watch's
number in the series.

He attaches the watch band
to the case with spring pins.

With the watch now
fully assembled,

It's time to inlay the yankee
stadium wooden chair accents.

Using a toothpick,

A worker applies epoxy glue

To the rectangular
recess in each link.

Then he places a wooden
link piece in each recess.

He follows the same process
for the dial's wooden bezel.

A worker sets the watch
aside for 24 hours

To let the adhesive set.

Then the worker buffs
the entire surface

On a cloth polishing wheel.

This process removes
the fingerprints

And dust and smoothes
those historic wood accents.

The watch automatically
winds with wrist movement

To reliably tell the time

While nostalgically
going back in time.

Narrator: if you're looking
for an affordable bicycle

That's durable and has great
shock absorption capabilities,

Then a bike made
of steel is for you.

It's a bit heavier
than a high-end bicycle

Made of aluminum
or carbon fiber,

But this rugged material
buys you a smoother ride

At a significantly lower price.

This three-speed
steel bicycle is sturdy

And comfortable enough
to ride recreationally

Or daily to school or work.

A cargo rack in the rear
can hold your purse,

Backpack or briefcase.

The bike is made
of chromoly steel,

Which is, pound-for-pound,
stronger than standard steel.

To prepare the bike's
tubular parts

Including the frame,

A worker cuts steel tube
with a horizontal band saw

Into specific-length pieces.

He then clamps
certain frame pieces

Into a milling machine,

Which will cut a curve
into one or both ends

Depending on
the piece's location

In the final assembly.

This notch, as it's called,

Will let the tube butt up

Against the side
of an adjacent tube

When the bike's frame
is assembled.

The notched edge is ragged,

So the worker smoothes it out
with a small belt sander.

Certain frame parts
are straight, others bent.

To make the bent ones,

Another worker places

The piece of tube
in a tube bender,

A press that forces the tube
against a curved dye.

Once all the frame parts
are ready,

A welder clamps
them in a fixture,

Which correctly positions
them for assembly.

He works with
a welding torch in one hand

And a rod of filler
metal in the other.

The torch melts adjacent tubes
at their meeting point

So that they fuse together.

The welder also melts

In some filler metal
to strengthen the joint.

The bicycle frame
is made up of nine major parts.

And the welder welds them
to each other in two sections,

Forming the rear triangle
and the front triangle.

This is the rear one,

Which alone requires
nine meticulous welds.

Once each triangle
is separately assembled,

He welds them together.

Another worker sprays the frame

With powder-coat primer,
then color.

Powder coat is
an industrial-grade,

Paint-like finish,

Which he bakes onto the metal

At almost 400 degrees
fahrenheit for 20 minutes.

When the frame comes
out of the oven,

Another worker presses
steel caps

Into what's called
the head tube,

That vertical tube
at the front of the frame

Which holds the handlebars
on top

And the fork for the front
wheel at the bottom.

Bearings inside the caps
let the handlebars

And fork turn left
and right with ease.

To put the bicycle together,

The worker suspends the frame
in an assembly stand

And then inserts
the bottom bracket,

Which will ultimately support
the bike's drivetrain system.

The bike's fenders
are made of sheet steel

That's shaped with
pressure-applying rollers.

The rear fender attaches
to the rear dropout

And at fender mounts
at two other locations

On the frame's rear triangle.

He screws the cargo
rack to middle

And rear rack supports.

Then, he inserts and bolts

The rear wheel
into the rear dropout.

The wheel hub has
three built-in gears.

The hub and rim
are made of aluminum,

Which is lightweight
and doesn't rust.

The wheel spokes
are stainless steel.

Next, the worker installs
the drivetrain system,

Inserting the crank arms,

Already mounted to
the chain ring,

Onto the bottom bracket.

He tightens the bolt securely
with a torque wrench.

Workers then insert the fork
into the bottom of the head tube

And chrome-plated steel
handlebars into the top mount,

The front fender
and front wheel,

Then install the pedals,

Vinyl seat, chain
and chain guard.

With the gear shifter

And front brake lever
on the handlebars,

This steel bicycle
is ready to hit the road.

Narrator:
for some pet owners,

Feeding raw food to
fido is a natural choice.

It harkens back
to the common ancestor

Of all dog breeds, the wolf.

In the wild,
wolves eat raw meat

And occasionally some greens,

So the theory goes that dogs
are genetically predisposed

To thrive
on a raw-meat diet.

Dogs have been domesticated
for thousands of years,

But when it comes
to their diet,

They can still
go a little wild.

Raw canine cuisine may be

A foreign concept
to some pet owners,

But it's becoming
more mainstream.

The makers of raw dog
food often mix fruits

And vegetables with meat
to provide fiber

And create a balanced meal.

The process starts

With a lot of slicing
and dicing.

A food worker chops the fruits
and veggies into smaller pieces

So they'll be able to go
through a grinder more easily.

He also removes the seeds
from the apples and the squash

Because the seeds aren't
as easily digested

As the rest of the fruit

And provide
no additional nutrition.

This raw pet food
recipe calls

For a variety of fruits
and vegetables.

Though, in total,

They will comprise
just 5% of the meal.

The rest of the raw blend will
consist of meat, bones,

Organs and fish.

Another food worker
chops up the chicken,

Which has been
organically raised

And has even been approved
for human consumption.

Except for the breasts,
all the parts of the chicken

Will be used in the main recipe.

This includes the heart, liver,
gizzards and the bones.

Raw, whole sardines,
anchovies and mackerel

Will add essential fatty acids

To the raw chicken blend.

All the ingredients
have been prepared

And are now ready
for grinding.

A worker feeds the components
to the grinder

In small batches
interspersing the meat,

Fish and the vegetables.

This ensures even distribution,

As the grinder minces everything
to a uniform particle size.

The result is a thick emulsion

Of finely
ground chicken meat,

Bones, vegetables,
fruits and fish.

She transfers the minced
raw ingredients to a mixer.

The revolving paddles
further blend the food.

After about 5 minutes
in the mixer,

All the ingredients
have been combined

Into one h*m* raw mass.

This chicken blend
is now complete.

The worker divides
it into 5-pound batches

And scoops it into bags.

She vacuum seals the bag.

Removing all the air inside

Will allow the raw blend
to stay fresh longer.

Refrigerated, it should last
for up to 10 days and,

If frozen, it should be good
for several months.

For the furry members
of the family,

Dinner is ready to be served.

To make some raw pet snacks,

A worker de-shells
new zealand

Green-lipped mussels,

A species that is believed
to have fast-acting

Anti-inflammatory properties.

After she cuts the mussels
free from the shells,

She places them on racks
for air-drying.

She transfers the rack
into a drying tent

Where fans keep air
circulating 24 hours a day.

As the mussels dry, they shrink.

After 72 hours
in the tent,

The moisture content
is substantially reduced.

Air drying has preserved
the flesh of the mussels

In the raw state

While preventing damage
to the nutrients

And enzymes they contain.

Now preserved,

She packs the mussels
into plastic bags

And adds an iron
oxide packet to absorb oxygen

And prevent spoilage.

This raw pet food is now ready
to nourish the wolf in your dog.

Narrator: before the invention
of electricity,

Criminal acts were
hidden by darkness.

Police officers carried
special lanterns

As they pursued suspects.

Today, craftsmen replicate
these lanterns for the movie

And television industries.

These props are authentically

Replicated pieces
of police history.

With a thick bull's-eye lens

To magnify the light
from the flame,

The 19th-century police lantern

Helped find bad guys
on shadowy streets.

To replicate
a vintage police lantern,

The craftsman starts
with a piece of steel.

Using a scribe, he traces
around a pattern

To transfer the outline
to the blank.

He marks notches for hinges
and for the latch

And etches the shape of the lens
hole in the center.

He draws two diagonal lines
in the lens hole area.

The point where the lines
intersect determines

The exact center.

He punches a divot into
the steel at this cross point.

He scribes lines
along the edges

For bending into
a reinforced border later on.

He cuts out the hinge
and latch notches following

The transferred pattern lines.

Next, he aligns
the center divot with a punch

And then activates the punch
to cut out the hole

For the lantern lens.

The craftsman now bends wire

To match the profile
of the lantern door.

He aligns the wire
with the scribed lines

On the edge of the door

And folds the metal over it.

Bending the door to the correct
curvature completes the part.

Following another pattern,

The craftsman marks the location

For vent holes in the blank

That will become
the lantern's main structure.

He cuts out the vent holes
where he's made the marks

Using a hand-operated punch.

He then rolls the blank
into a cylinder.

It takes a couple of passes

To achieve
the correct curvature.

Moving on to the lantern's
lens holder,

The craftsman crimps
a bead around one end.

This bead helps to retain

The bull's-eye
lens in the holder.

Returning to the lantern body,

He hammers the top rim
around the cap.

He preps the surface
for soldering

With a chemical
cleaning agent known as flux.

He then solders the joint

To secure the top
to the lantern.

He also solders
a raised panel to the back.

This substantial panel serves
as support for handles.

He then cleans the solder
joints with acetone.

Next, he wraps metal hinges
around the wire

That runs through
the notches in the door.

He crimps the hinges
together at the ends

And positions the door
on the lantern body.

He adjusts the hinges

So the ends
sit level on the lantern.

He solders the hinges
to the steel structure.

The craftsman inserts
the bull's-eye lens

Assembly into the hole

In the center
of the lantern door,

And he solders the joint.

He pins and solders

The two tiers
of a copper chimney.

He places the chimney
over the hole in the top

Of the lantern

And tucks more pins
into holes in the chimney.

The craftsman installs
a decorative part in the top,

One that won't obstruct
the chimney hole.

He assembles the handles
to the raised panel

At the back of the lantern.

Once the soldered seam
hardens, he files it down.

The craftsman tests the latch
on the door and confirms

That it operates perfectly.

After taping up
the lens and handles,

He spray paints
the lantern black.

Now it's time to assemble
the oil-burning mechanism.

First, the craftsman melts

Solder onto a threaded
brass collar

And transfers it
to the oil tank.

He reheats the solder
to melt it into the joint.

He inserts the wick in the tank

And screws the burner
to the collar.

And that completes
the lantern's light source.

This replica police lantern
will be a working prop

Designed to shine on tv
and the movies.
