Narrator: in the american
Wild west, the gun ruled,

And that gun was usually
A six-shooter revolver.

Today, replicas
Of those revolvers

Can take you back to dodge city,

And they do
At cowboy shooting competitions.

It's a chance to engage

In a little old-fashion
Gunslinging for old time's sake.

With its six-shot cylinder

And innovative
Cocking mechanism,

The 1873 colt was carried
By the likes of jesse james.

They start
These automatic replicas

By shaping and machining
The gun's frame.

A computerized blade
Carves the cylinder.

It cuts slots
For the ammunition

And notches for rotating the
Cylinder after a shot is fired.

A technician
Files down rough edges

So the parts
Will fit together perfectly.

He then screws the curved grip
And the trigger guard

To the frame.

He assembles the wooden grip
Casing to the metal back strap

And attaches them to the grip.

Once he confirms
It's a good fit,

He removes the casing the writes
The gun's serial number inside.

He stamps a matching number
Onto the grip

And polishes it and the gun's
Frame to a glossy finish.

He now rolls the model number

And other
Identifying information

Onto the gun's barrel.

To add a bit of flourish,

An artist engraves designs

Copying the artwork
On an original colt.

Another worker now dips
The parts in hot salts,

Then in cold water.

A reaction occurs

That both hardens the parts
A bit and tints them.

In this case,
They turn a bronze color.

This is called
Color case hardening.

The grip and trigger guard

Have been removed from
The gun frame for color casing.

This makes it easier
For the technician

To install the cartridge
Loading gate on the frame.

He files down the mechanism
For rotating the cylinder

To make the dimensions perfect.

He then inserts a bushing
And a pin

In the cylinder's center.

He uses that pin to install
The cylinder in the gun frame.

The pin will also serve
As the axis

For the cylinder
To revolve on.

He slides a couple of test slugs
Into the chambers

To confirm the gap between
The cylinder and gun frame

Is spot on.

He then fits the gun barrel
To the frame.

And, using
A special measuring rod,

He checks the alignment
Of the cylinder and barrel.

He tightens the barrel
To the gun frame,

Using a stick as a lever.

The technician aims
The assembled gun

And eyeballs the alignment
Of the barrel to the frame.

Once he's certain

The configuration
Is right on target,

He installs the gun's hammer
And trigger.

He pops the cylinder
Back into the gun frame

And inserts the rod
For ejecting spent ammunition.

He screws a spring
Into the side of the hammer

And cocks it
In its three different positions

To verify that it's
In working order.

He then reattaches the grip
And trigger guard.

He assembles a flat spring
To the curved grip.

This is the main spring.

It transfers energy
From the trigger to the hammer

To cause the revolver to fire.

Then it's over
To a government testing facility

Called the proof house.

Behind bulletproof glass,

Special equipment
Fires ammunition

At three times
The usual operating pressure.

If the gun can handle this,
It's deemed safe to operate.

After a few more parts
Have been color cased,

This revolver replica is ready
For its target market.

And that would be history buffs

Who are interested
In a real blast from the past.

Narrator: arc trainers can
Give you a full-body workout.

They provide a number
Of exercise programs

To choose from,

Like strength training,
Weight loss, and cardio.

They monitor such things

As heart rate
And calories burned.

Like any piece
Of exercise equipment,

Using one properly is the key
To a safe and healthy workout.

Arc trainers are made
To give you

A wide range of incline
And resistance levels

To let you train as easy
Or as hard as you like.

To start, a tube laser

Machine-cuts and profiles
The steel tubing

That will make
The arc trainer's side frame.

A worker cleans the steel tubes,
Then runs them

Through a computer-controlled
Roll-forming machine.

This machine shapes
All the steel

Used to build
The arc trainer's frame.

They use a robot to weld
All the parts together

Because robotic welding
Is more consistent and accurate

Than hand-welding.

The completed frames
Then get a surface preparation,

Giving the steel
A uniform finish

That is now ready
For powder painting.

Workers then paint the frames

Using an electrostatic
Paint process.

These guns spray electrically
Charged paint particles

That are drawn
To the grounded frames

In a smooth and even coat.

The frames then bake in an oven
For 40 minutes

To cure the paint.

Next come the handlebars.

A worker then makes them
By lubricating a rubber tube

And sliding it
Onto an assembly frame.

He then locks
A preformed metal tube in place

And lubricates it, as well.

He turns a handwheel,

Which brings
The two tubes together,

Forming the handgrip.

He completes the assembly
By screwing on an end cap.

Meanwhile, a worker assembles
The control panel

By putting on the overlays
For the user interface.

She then hooks up
The printed circuit board

That controls the unit.

She closes the housing

But leaves
The connectors exposed

For connection
To the mainframe later.

A worker then attaches a steel
Support fixture onto the frame.

Next comes
This drive-wheel assembly,

Which he bolts
Onto the support fixture.

He puts a drive belt
Around a pulley

That provides various
Resistance levels for the user

And rolls the belt
Onto the drive wheel.

He then uses a pneumatic tool
To tighten down the pulley,

Which stretches the drive belt

And sets it
To the appropriate tension.

Next, he attaches
The computer board

That controls
The various fitness programs.

A worker then installs
The leg bars

Onto the arc trainer's frame

And attaches a foot pedal
Onto each leg bar.

He installs linkage bars
Onto the drive-wheel assembly.

Then he aligns the drive wheel

And puts on
The molded front housing...

Followed by
The protective side covers.

He connects a linkage bar

That extends from each leg bar
To the drive wheel,

Then connects one linkage bar
To each arm handle.

He makes sure all the linkage
Bars are working properly.

Finally, he tests

The free-floating foot pedals
And the dual-action arms,

As well as all the other
Functions and features.

These arc trainers are
High-tech exercise machines.

Some models even come
With a tv.

Narrator:
Used-oil furnaces generate heat

By burning used oil
Without having to refine it.

These furnaces are found
In automobile shops,

Maintenance facilities,
And construction sites.

Transport fleets and trucking
Companies also use them

To turn the used oil
They produce

Into heat for their facilities.

It takes a special furnace
To burn used oil.

Used oil is thick and dirty

Compared
To residential fuel oil

And must be turned
Into a fine mist

To burn properly.

It all starts with
A computer-controlled laser

Making what's called
The front and rear flue plates

Out of steel.

The plates
For this hot-air furnace

Are made of stainless
Or hot-rolled steel

Depending on the size
Of the unit.

A worker then makes what's
Known as the heat exchanger

By joining
The flue plates together

With steel tubes
Called flue tubes.

This device is called
A swagger machine.

It expands just the ends
Of the flue tubes,

Binding them in place
With the flue plate.

Next, he assembles the section
In which hot gases collect

After passing
Through the flue tubes

On their way
Out of the furnace.

He then sets
A combustion chamber

On the top
Of the heat exchanger

And welds them together.

He completes
The heat-exchanger assembly

By welding on a base equipped
With two air-deflector plates.

These square plates
Help direct the ambient air

As it enters the furnace

And circulates
Around the combustion chamber.

Meanwhile, an electrostatic
Powder-coating machine

Paints the outside covers
For the furnace.

Next, they put
On inner air deflectors,

Then assemble the cabinet.

They bolt everything in place,
Then put on an insulated door.

Now he hooks up
A blower control box.

This electrical box regulates

When hot air
Is sent into a room.

A worker then connects
A tester box

To the temperature controls

That measure the temperature
Inside the furnace.

He runs a number of tests

To confirm that both the blower
And the burner

Will turn on or off
When they're supposed to.

He verifies the operation
Of the door

That allows
For cleaning out ash residue.

A technician installs
A 100-watt pencil heater

Inside a brass nozzle adaptor,

Then threads a thermostat
Into it.

This nozzle adaptor
Heats the oil

And turns it into a fine mist
So it burns properly.

She then attaches assembly
Fittings to the adaptor

So she can later mount it
Inside a burner housing.

She checks these fittings
With a leveling tool

To ensure the adaptor will go
On straight inside the housing.

She also installs an assembly
That controls

Oil flow, temperature,
And air pressure.

Then she mounts
The nozzle adaptor

And covers it
With a retention head

That shapes the flame
For optimal heat,

Completing the burner assembly.

A worker then hooks up

The used-oil
And compressed-air lines

To begin testing the burner.

He turns on the oil,
Ignites the burner,

And looks through
An observation port

To verify the burner
Is working properly.

A closer look shows the flame
Is at the right intensity

For optimal heat
With minimal emissions.

The furnace is now ready to turn
Used oil into useful heat.

Narrator: top-of-the-line pizza
Cutters and vegetable peelers

Can be a pleasure to use.

They make preparing and serving
Your favorite foods

Quicker and easier

And are ergonomically designed
For style and comfort.

They are also easy to clean
And guaranteed for life.

Vegetable peelers and pizza
Cutters work like a charm,

Making straight cuts

Without damaging your pans
Or your fingers.

Quality pizza cutters start

With cutlery-grade,
High-carbon stainless steel

From which a stamping press
Punches the cutter blades.

The blades go

Through a three-step
Heat-treating process.

First, they enter
A high-temperature furnace.

Then it's into a deep freezer

To maximize hardness
And corrosion resistance.

Finally, they go
Into a tempering oven,

Which increases the durability
Of the metal.

A polishing machine
With two buffing heads

Then polishes both sides
Of the blade,

Giving it a protective
And cosmetic finish.

A worker than loads the blade
Onto a bevel-grinding machine

That thins out the edge
Of the blade.

It grinds a beveled edge
That is thin enough to cut pizza

But not sharp enough

To cut your finger
Or damage a cutting surface.

A worker puts
A steel-bar insert

Into an injection
Molding machine

That makes
The soft-polymer handle.

He then cools it down in water.

He puts the handles
On an extraction fixture

Which removes the inserts,

Making the handles
Ready for assembly

Along with all
The other molded parts.

He then attaches what's called
A swing arm to the blade holder,

And he secures it in place
With a screw.

He dips the tip of the blade
Holder into lubricant

And uses
A pneumatic-assembly fixture

To insert the blade holder
Into the handle permanently.

Using the swing arm,

He snap-fits the blade
Onto the blade holder

And hides the swing-arm screw
With a cover cap.

Finally, he ensures the blade
Rolls properly and safely

So it will cut through pizza
With ease.

The finest vegetable peelers

Also do their job
Quickly and effectively.

They also start

With cutlery-grade
Stainless-steel blades

That undergo tempering

To ensure the metal is durable
And corrosion-resistant.

After cleaning and polishing,

The blades are dried

In a vibrating medium
Of ground corncob,

Then removed from the tub
By a magnet.

The blades are now ready
For sharpening.

A worker mounts
The peeler blades

On a computer-controlled
Edge-grinding machine.

The grinder sharpens one edge
Of each blade at a time.

Once both sides of the peeler
Blades are fully sharpened,

They're ready for assembly.

Meanwhile,
An injection molding machine

Makes the blade holders.

A worker dips each blade holder
Into lubricant

And inserts it into the molded
Soft-polymer handle,

Joining them together
Permanently.

Finally, he attaches the blade

By deflecting the holder
Just enough

To insert the tip of the blade
Into a tiny hole.

These top-quality
Vegetable peelers

Are sold individually
Or in combination

With other kitchen utensils
Like pizza cutters,

And they sure are handy
In the kitchen,

Even if you're not.
