Narrator: throughout europe
In the late 1700s,
4
00:00:56,379 --> 00:01:00,551
Peaked caps were traditionally
Worn by industrial workers.
5
00:01:00,551 --> 00:01:02,551
Today, they are worn
By professionals
6
00:01:02,551 --> 00:01:06,275
Such as security personnel,
Members of the military,
7
00:01:06,275 --> 00:01:09,137
And police officials
That wear uniforms.
8
00:01:13,413 --> 00:01:16,000
In the united kingdom,
Some police officers
9
00:01:16,000 --> 00:01:18,793
Still wear
The classic custodian helmet,
10
00:01:18,793 --> 00:01:21,413
But now many officers
Have chosen to wear
11
00:01:21,413 --> 00:01:25,379
The lightweight, comfortable,
And practical peaked cap.
12
00:01:27,655 --> 00:01:30,862
To make these caps,
A hat maker, or a milliner,
13
00:01:30,862 --> 00:01:33,896
Assembles a number of components
Using patterns
14
00:01:33,896 --> 00:01:38,517
To cut out the required pieces
Of wool, foam, and plastic.
15
00:01:38,517 --> 00:01:41,793
A milliner bends a strip
Of polypropylene plastic
16
00:01:41,793 --> 00:01:44,275
Into a circle.
17
00:01:44,275 --> 00:01:47,206
She sews the joint
With a high-strength thread,
18
00:01:47,206 --> 00:01:51,517
Creating the hat band
That will go around the head.
19
00:01:51,517 --> 00:01:54,793
She positions a smaller piece
Of polypropylene,
20
00:01:54,793 --> 00:01:58,724
Known as the badge support,
And sews it in place.
21
00:01:58,724 --> 00:02:01,551
The support will prevent
The weight of a police badge
22
00:02:01,551 --> 00:02:04,000
From distorting
The shape of the hat.
23
00:02:06,448 --> 00:02:09,724
These crescent-shaped components
Are pieces of wool
24
00:02:09,724 --> 00:02:13,241
Glued to thin, flexible foam.
25
00:02:13,241 --> 00:02:17,137
She sews the crescents together,
Creating a circular piece,
26
00:02:17,137 --> 00:02:19,137
Which will form the bevel.
27
00:02:19,137 --> 00:02:22,275
She uses a specialized,
Long-arm sewing machine,
28
00:02:22,275 --> 00:02:24,862
Which has been customized
To make hats.
29
00:02:27,413 --> 00:02:31,517
The seams are carefully ironed
Flat to prevent any bulging.
30
00:02:31,517 --> 00:02:34,724
If the iron is too hot,
The foam will melt.
31
00:02:34,724 --> 00:02:37,551
Too cool,
And the wool won't flatten.
32
00:02:37,551 --> 00:02:40,965
She aligns two strips
Of 100% wool fabric
33
00:02:40,965 --> 00:02:43,551
And sews them together
At the ends.
34
00:02:43,551 --> 00:02:45,931
This piece will cover
The plastic stiffener
35
00:02:45,931 --> 00:02:49,586
Forming the outer band.
36
00:02:49,586 --> 00:02:51,827
To ensure the sizing is correct,
37
00:02:51,827 --> 00:02:54,965
The milliner places the wool
Cover over the stiffener.
38
00:03:00,275 --> 00:03:01,724
The stiffener is installed
39
00:03:01,724 --> 00:03:05,379
At the end
Of the production process.
40
00:03:05,379 --> 00:03:09,241
Next, the milliner irons
The seams of the band covers.
41
00:03:11,724 --> 00:03:14,517
She finishes the band covers
On a sewing machine
42
00:03:14,517 --> 00:03:16,517
Known as a flat bed
43
00:03:16,517 --> 00:03:19,827
And creates a fold
To hold the plastic stiffener
44
00:03:19,827 --> 00:03:22,724
And sews the edges together.
45
00:03:22,724 --> 00:03:26,137
Then the band cover is sewed
To the bevel.
46
00:03:26,137 --> 00:03:28,827
While it's difficult to attach
Two pieces of cloth
47
00:03:28,827 --> 00:03:30,310
At different angles,
48
00:03:30,310 --> 00:03:35,448
This step creates an even seam
That runs 360 degrees.
49
00:03:35,448 --> 00:03:37,724
It takes at least six months
Of training
50
00:03:37,724 --> 00:03:39,551
To learn how to make hats.
51
00:03:42,310 --> 00:03:45,137
The crown is made
From three materials --
52
00:03:45,137 --> 00:03:48,724
A combination of wool and foam,
53
00:03:48,724 --> 00:03:51,655
A polyester lining,
54
00:03:51,655 --> 00:03:54,344
And a protective-grade
P.V.C. Layer.
55
00:03:56,517 --> 00:03:59,482
Once the three materials
Have been sewn together,
56
00:03:59,482 --> 00:04:04,068
The machinist trims
The perimeter of the crown.
57
00:04:04,068 --> 00:04:05,896
She marks the side edges
58
00:04:05,896 --> 00:04:08,586
And aligns them with the seams
On the bevel.
59
00:04:11,379 --> 00:04:14,034
Then she sews the crown
To the bevel.
60
00:04:14,034 --> 00:04:17,344
Having spent a great deal
Of time perfecting the skills,
61
00:04:17,344 --> 00:04:19,620
This milliner
Makes it look easy.
62
00:04:22,620 --> 00:04:26,206
Finally, the components
Begin to resemble a hat.
63
00:04:28,551 --> 00:04:31,931
Using a polypropylene template,
The machinist positions
64
00:04:31,931 --> 00:04:35,448
And marks
Two spots on the bevel.
65
00:04:35,448 --> 00:04:39,413
She places two small brass rings
On a special device
66
00:04:39,413 --> 00:04:42,482
And aligns the marks
With the device's posts,
67
00:04:42,482 --> 00:04:46,482
Which cut out two holes
Through the fabric.
68
00:04:46,482 --> 00:04:50,034
Then she places two cup-shaped
Rings on the posts,
69
00:04:50,034 --> 00:04:52,000
And the machine
Punches them down,
70
00:04:52,000 --> 00:04:55,551
Forming eyelets for ventilation.
71
00:04:55,551 --> 00:04:57,689
Next,
The polypropylene stiffener
72
00:04:57,689 --> 00:05:00,068
Is inserted into the hat.
73
00:05:00,068 --> 00:05:05,482
Finally, the hat begins
To take on its final shape.
74
00:05:05,482 --> 00:05:09,413
The tag containing the hat's
Size is sewed on hat band.
75
00:05:11,482 --> 00:05:15,034
She places a checkered-pattern
Band on the brim of the hat,
76
00:05:15,034 --> 00:05:19,620
Called dicing
Or the sillitoe tartan.
77
00:05:19,620 --> 00:05:21,827
The milliner inserts
A replica badge
78
00:05:21,827 --> 00:05:25,586
Through holes
In the badge support
79
00:05:25,586 --> 00:05:28,172
And secures it with a pin.
80
00:05:28,172 --> 00:05:29,517
This is a replica,
81
00:05:29,517 --> 00:05:34,482
Since we can't show
Real police badges on tv.
82
00:05:34,482 --> 00:05:37,931
Next, the milliner sews
The peak onto the band.
83
00:05:42,655 --> 00:05:44,275
It took a highly skilled
Milliner
84
00:05:44,275 --> 00:05:47,482
More than half an hour
To sew this hat.
85
00:05:47,482 --> 00:05:49,413
They might look straightforward,
86
00:05:49,413 --> 00:05:52,413
But peaked caps
Are surprisingly complex.
87
00:06:02,241 --> 00:06:06,034
Narrator:
A home water heater stores
And heats water in a tank.
88
00:06:06,034 --> 00:06:07,551
This is how it works.
89
00:06:07,551 --> 00:06:09,137
When you turn on a faucet,
90
00:06:09,137 --> 00:06:11,827
Hot water flows out of the tank
From the top,
91
00:06:11,827 --> 00:06:15,000
While cold water flows
Into the tank from the bottom.
92
00:06:15,000 --> 00:06:18,206
Conventional water heaters
Are fueled by natural gas,
93
00:06:18,206 --> 00:06:22,517
Electricity, propane, or oil.
94
00:06:22,517 --> 00:06:25,689
This company custom-builds
Several types of water heaters
95
00:06:25,689 --> 00:06:28,482
For use with different types
Of heat sources,
96
00:06:28,482 --> 00:06:32,758
Such as boilers, heat pumps,
And solar panels.
97
00:06:32,758 --> 00:06:35,620
Each work order includes
A picture outlining
98
00:06:35,620 --> 00:06:38,413
The pipe configuration
And the connecting valves,
99
00:06:38,413 --> 00:06:43,620
Along with a list of the
Water heater's specifications.
100
00:06:43,620 --> 00:06:45,241
To make a copper tank,
101
00:06:45,241 --> 00:06:50,310
A technician cuts a thick sheet
Of copper to a specified length.
102
00:06:50,310 --> 00:06:53,586
He aligns the end of the sheet
To the gradation on the table
103
00:06:53,586 --> 00:06:56,724
That corresponds to
The tank's circumference.
104
00:06:56,724 --> 00:07:01,689
Then he actives the guillotine
Blade with a foot pedal.
105
00:07:01,689 --> 00:07:05,482
A computer-guided machine
Punches holes for the valves.
106
00:07:05,482 --> 00:07:07,620
This water heater requires
Two valves
107
00:07:07,620 --> 00:07:09,586
At each end of the heating coil
108
00:07:09,586 --> 00:07:12,482
And one that will connect
The water pipe to the tank.
109
00:07:16,620 --> 00:07:18,724
The technician inserts
The copper sheet
110
00:07:18,724 --> 00:07:20,965
Into a mechanical roller.
111
00:07:20,965 --> 00:07:22,724
The rollers apply pressure,
112
00:07:22,724 --> 00:07:25,379
Forming the sheet
Into an open cylinder.
113
00:07:29,551 --> 00:07:32,310
One end of the cylinder
Is clamped into a machine
114
00:07:32,310 --> 00:07:34,413
That welds linear seams.
115
00:07:38,482 --> 00:07:40,241
The technician inserts
The other end
116
00:07:40,241 --> 00:07:42,206
Of the cylinder
Through the machine
117
00:07:42,206 --> 00:07:45,241
And joins it
Against the clamped end.
118
00:07:45,241 --> 00:07:47,655
The machine is programmed
To weld a seam
119
00:07:47,655 --> 00:07:51,172
To the length
Of the connected ends.
120
00:07:51,172 --> 00:07:53,689
The technician monitors
The welding arm
121
00:07:53,689 --> 00:07:57,206
Through a u.V. Lens
To protect his eyes.
122
00:07:57,206 --> 00:07:59,275
The machine stops automatically
123
00:07:59,275 --> 00:08:03,310
When it reaches
The programmed seam length.
124
00:08:03,310 --> 00:08:05,379
This process closes the cylinder
125
00:08:05,379 --> 00:08:07,862
With a strong,
Pressure-resistant seam,
126
00:08:07,862 --> 00:08:12,103
Creating the water-heater
Tank's structural component.
127
00:08:12,103 --> 00:08:15,620
Another technician places
The tank's top on a press.
128
00:08:15,620 --> 00:08:18,620
The press punches a hole
For a threaded pipe fitting.
129
00:08:18,620 --> 00:08:21,344
The fitting connects the pipe
To the hot water.
130
00:08:21,344 --> 00:08:22,965
Using a different press,
131
00:08:22,965 --> 00:08:24,689
The technician makes
Another hole
132
00:08:24,689 --> 00:08:27,103
Into the cylinder
For a threaded fitting.
133
00:08:27,103 --> 00:08:29,310
This fitting connects to
An electrical element
134
00:08:29,310 --> 00:08:32,758
That heats water
In conjunction with a boiler.
135
00:08:32,758 --> 00:08:35,517
Another technician makes
The tank's heating coil
136
00:08:35,517 --> 00:08:39,413
By running a straight copper
Tube through three rollers.
137
00:08:39,413 --> 00:08:41,689
The tube is bent under pressure,
138
00:08:41,689 --> 00:08:44,896
Forming it into a coiled shape.
139
00:08:44,896 --> 00:08:47,827
The heat from the boiler,
Pump, or solar panel
140
00:08:47,827 --> 00:08:49,689
Flows through the heating coil,
141
00:08:49,689 --> 00:08:51,896
Heating the water stored
In the tank.
142
00:08:56,448 --> 00:08:59,655
Since the copper-tube wall
Is too thin to weld,
143
00:08:59,655 --> 00:09:03,862
A technician uses a fusing
Technique known as brazing.
144
00:09:03,862 --> 00:09:06,965
This metal-joining process
Brazes a flow fitting
145
00:09:06,965 --> 00:09:08,620
On one end of the heating coil
146
00:09:08,620 --> 00:09:10,793
And a return fitting
On the other.
147
00:09:13,655 --> 00:09:17,344
Next, the heating coil
Is placed in the tank.
148
00:09:17,344 --> 00:09:21,103
The fittings protrude through
A hole at the top and bottom.
149
00:09:21,103 --> 00:09:23,862
The technician secures each one
With a nut,
150
00:09:23,862 --> 00:09:26,620
Then tightens the nuts
With an impact wrench.
151
00:09:28,620 --> 00:09:32,620
Like the dome top, the bottom
Component's edges are grooved,
152
00:09:32,620 --> 00:09:34,517
Allowing the tank
To fit perfectly
153
00:09:34,517 --> 00:09:36,344
Into the cylinder base.
154
00:09:39,620 --> 00:09:42,655
Once the top and bottom
Components are installed,
155
00:09:42,655 --> 00:09:44,758
The tank goes back
To the brazing station
156
00:09:44,758 --> 00:09:46,482
For final assembly.
157
00:09:49,448 --> 00:09:52,068
A welder brazes
The top and bottom components
158
00:09:52,068 --> 00:09:53,379
To the cylinder,
159
00:09:53,379 --> 00:09:55,758
Then he brazes
A feed fitting to a hole
160
00:09:55,758 --> 00:09:57,620
Near the bottom of the tank.
161
00:09:57,620 --> 00:10:00,034
This location is where
Cold water enters
162
00:10:00,034 --> 00:10:01,758
The tank to be heated.
163
00:10:05,379 --> 00:10:09,413
Next, a technician conducts
A quality-control test.
164
00:10:09,413 --> 00:10:13,206
He blocks the three fittings,
Fills the cylinder with air,
165
00:10:13,206 --> 00:10:16,620
Then submerges the tank in water
To check for air bubbles,
166
00:10:16,620 --> 00:10:18,310
Which would indicate a leak.
167
00:10:24,551 --> 00:10:26,862
A stainless-steel water heater
Is constructed
168
00:10:26,862 --> 00:10:28,344
Just like a copper heater,
169
00:10:28,344 --> 00:10:30,862
Except that they don't require
Any brazing.
170
00:10:34,379 --> 00:10:38,275
A robot sprays the tanks with
Expandable polyurethane foam
171
00:10:38,275 --> 00:10:40,068
For insulation.
172
00:10:40,068 --> 00:10:42,655
The customer selects
The degree of insulation,
173
00:10:42,655 --> 00:10:46,310
One to four inches thick.
174
00:10:46,310 --> 00:10:50,482
The foam takes just five minutes
To cure.
175
00:10:50,482 --> 00:10:54,000
As the tank stores hot water,
The insulation reduces
176
00:10:54,000 --> 00:10:57,000
The amount of heat
The tank loses over time.
177
00:11:07,862 --> 00:11:09,413
Narrator:
Electrically powered vehicles
178
00:11:09,413 --> 00:11:12,413
May seem like
A 21st-century phenomenon,
179
00:11:12,413 --> 00:11:15,689
But they were actually
First invented in the 1880s.
180
00:11:15,689 --> 00:11:18,034
During that time,
They were very popular,
181
00:11:18,034 --> 00:11:21,586
Until combustion-engine vehicles
Became the new normal.
182
00:11:21,586 --> 00:11:23,482
Today,
These electrically powered
183
00:11:23,482 --> 00:11:28,344
Alternative-fuel vehicles
Are making a comeback.
184
00:11:28,344 --> 00:11:32,310
This manufacturer produces
A wide range of electric boats.
185
00:11:32,310 --> 00:11:35,172
Thanks to powerful batteries,
Some of these vehicles
186
00:11:35,172 --> 00:11:39,620
Can travel
Over 35 miles per hour.
187
00:11:39,620 --> 00:11:42,965
Craftspeople apply
A gel-coat skin to a mold,
188
00:11:42,965 --> 00:11:45,310
Using a product
Derived from vinyl.
189
00:11:47,379 --> 00:11:50,413
Then they layer on
A dry fiberglass fabric
190
00:11:50,413 --> 00:11:54,344
And vacuum-bag
The entire assembly.
191
00:11:54,344 --> 00:11:57,034
The vacuum suction
Draws in liquid resin,
192
00:11:57,034 --> 00:11:59,344
Infusing the material.
193
00:11:59,344 --> 00:12:02,413
A craftsman marks a dry spot
As a test point
194
00:12:02,413 --> 00:12:05,482
To monitor and ensure
Complete saturation.
195
00:12:08,413 --> 00:12:11,586
The infusion process
Takes about two hours.
196
00:12:11,586 --> 00:12:15,413
Once complete, the assembly
Will cure for four to six hours,
197
00:12:15,413 --> 00:12:19,172
Depending on the general
Humidity and temperature levels.
198
00:12:19,172 --> 00:12:22,862
Once cured, the assembly
Is removed from the mold.
199
00:12:22,862 --> 00:12:25,103
Despite the structure's
Light weight,
200
00:12:25,103 --> 00:12:29,206
This deck is incredibly
Strong, rigid, and durable.
201
00:12:32,310 --> 00:12:36,655
The fiberglass decks and hulls
Make up the boat's shells.
202
00:12:39,000 --> 00:12:42,275
A craftswoman applies
A high-strength marine glue
203
00:12:42,275 --> 00:12:46,103
To a recessed area of the deck.
204
00:12:46,103 --> 00:12:49,758
She installs an anti-skid
Deck insertion.
205
00:12:49,758 --> 00:12:55,000
This material is a composite
Designed to resemble wood.
206
00:12:55,000 --> 00:12:57,655
Unlike real wood,
This composite material
207
00:12:57,655 --> 00:13:00,000
Will last the lifetime
Of the boat
208
00:13:00,000 --> 00:13:04,551
And won't require
Any additional maintenance.
209
00:13:04,551 --> 00:13:08,379
The craftswoman uses a roller
To apply pressure evenly
210
00:13:08,379 --> 00:13:10,620
Across the entire
Decking surface.
211
00:13:10,620 --> 00:13:14,413
This step will eliminate
Any unwanted air pockets.
212
00:13:14,413 --> 00:13:16,793
Next, a mirror-image
Decking section
213
00:13:16,793 --> 00:13:19,620
Is applied to the other side.
214
00:13:19,620 --> 00:13:23,379
A specialist installs
The electrical-wiring harness.
215
00:13:23,379 --> 00:13:26,482
To avoid corrosion,
Marine-grade wiring is stored
216
00:13:26,482 --> 00:13:28,724
In a sealed environment
Under the deck.
217
00:13:32,413 --> 00:13:34,448
Since the decking
Is lightweight,
218
00:13:34,448 --> 00:13:38,068
It only takes two people to lift
And install it on the hull.
219
00:13:40,241 --> 00:13:43,137
The lip of the deck
Fits snugly into place.
220
00:13:46,379 --> 00:13:51,172
The most powerful boat models
Require lithium-ion batteries.
221
00:13:51,172 --> 00:13:54,275
These boats are built
With military-grade foam.
222
00:13:54,275 --> 00:13:56,655
The density of the foam
Adds structure,
223
00:13:56,655 --> 00:14:00,379
Causing the boat
To become unsinkable.
224
00:14:00,379 --> 00:14:03,103
Using a hoist, technicians
Install the deck
225
00:14:03,103 --> 00:14:06,310
Of a large, powerful
Electric boat.
226
00:14:06,310 --> 00:14:09,034
The deck lip slides
Over the top of the hull.
227
00:14:11,310 --> 00:14:12,965
Depending on the boat model,
228
00:14:12,965 --> 00:14:15,793
The manufacturer uses
Either lithium-ion
229
00:14:15,793 --> 00:14:19,896
Or lead-acid batteries
As a power source.
230
00:14:19,896 --> 00:14:23,068
A specialist installs a series
Of marine-grade
231
00:14:23,068 --> 00:14:26,103
Dc31 lead-acid batteries.
232
00:14:26,103 --> 00:14:28,793
At 6 volts, 225 amps,
233
00:14:28,793 --> 00:14:31,551
They're similar to batteries
Used in cars.
234
00:14:31,551 --> 00:14:35,931
By contrast, the 7.7-kilowatt
Lithium-ion batteries
235
00:14:35,931 --> 00:14:38,551
Pack a charge of 48 volts.
236
00:14:38,551 --> 00:14:42,000
The batteries are installed
Under the seats.
237
00:14:42,000 --> 00:14:45,379
To create a watertight seal
Between the deck to the hull,
238
00:14:45,379 --> 00:14:47,379
A craftsman installs
A rubber bumper
239
00:14:47,379 --> 00:14:49,896
Around the perimeter
Of the boat.
240
00:14:49,896 --> 00:14:52,310
Holes have been pre-drilled
To avoid cracking
241
00:14:52,310 --> 00:14:54,344
When installation is complete.
242
00:14:57,482 --> 00:14:59,758
This manufacturer sources
Their motors
243
00:14:59,758 --> 00:15:02,034
From an outside
Electric-motor company,
244
00:15:02,034 --> 00:15:06,448
Which also builds motors
For cars.
245
00:15:06,448 --> 00:15:10,379
The fin, made of aluminum
Encased in marine-grade rubber,
246
00:15:10,379 --> 00:15:14,517
Is installed on the bottom
Of the motor.
247
00:15:14,517 --> 00:15:17,827
The propeller attaches
To the motor with a zinc nut.
248
00:15:20,000 --> 00:15:22,586
Two circuit boards located
On board
249
00:15:22,586 --> 00:15:25,068
Will send instructions
To the motor.
250
00:15:25,068 --> 00:15:28,206
A waterproof cover is placed
On top of the circuit boards
251
00:15:28,206 --> 00:15:30,103
For added protection.
252
00:15:30,103 --> 00:15:34,241
Locknuts with nylon washers will
Prevent unnecessary vibrations
253
00:15:34,241 --> 00:15:36,137
While the motor is on.
254
00:15:36,137 --> 00:15:38,000
With the steering cables
Installed,
255
00:15:38,000 --> 00:15:40,413
The entire unit pivots
Right and left,
256
00:15:40,413 --> 00:15:43,344
Allowing the pilot
On deck to steer.
257
00:15:43,344 --> 00:15:45,137
The powerful motor is equivalent
258
00:15:45,137 --> 00:15:48,000
To a 10-horsepower
Combustion engine,
259
00:15:48,000 --> 00:15:49,862
And because it sits
In the water,
260
00:15:49,862 --> 00:15:52,310
It stays cool and quiet.
261
00:15:52,310 --> 00:15:55,448
Finally, a craftswoman places
The boat's sun canopy
262
00:15:55,448 --> 00:15:56,827
Over the framework.
263
00:15:56,827 --> 00:15:59,310
This will allow customers
To add solar panels
264
00:15:59,310 --> 00:16:01,034
For charging the boat.
265
00:16:01,034 --> 00:16:03,551
Also, a customer can choose
The colors
266
00:16:03,551 --> 00:16:06,275
For both their canopies
And upholstery.
267
00:16:06,275 --> 00:16:08,379
There's no denying
That electric boats
268
00:16:08,379 --> 00:16:10,620
Are the future of fun
On the water.
269
00:16:20,172 --> 00:16:21,793
Narrator:
Modern fencing is a sport
270
00:16:21,793 --> 00:16:26,000
Consisting of three disciplines,
One of which is foil fencing.
271
00:16:26,000 --> 00:16:28,379
While in play,
A lightweight foil sword
272
00:16:28,379 --> 00:16:30,620
Is used to score points.
273
00:16:30,620 --> 00:16:33,379
Points can be scored
When the tip of a player's sword
274
00:16:33,379 --> 00:16:38,137
Makes contact onto
Their opponent's torso.
275
00:16:38,137 --> 00:16:40,413
A fencing foil is
A piece of equipment
276
00:16:40,413 --> 00:16:43,310
That should only be used
By trained professionals.
277
00:16:43,310 --> 00:16:46,655
This sword doesn't have
A sharp edge or pointed tip.
278
00:16:46,655 --> 00:16:49,620
It's all about scoring hits.
279
00:16:49,620 --> 00:16:53,758
Fencing foils are made
Out of thin steel bars.
280
00:16:53,758 --> 00:16:56,758
The steel is a low-carbon,
Nickel-rich alloy
281
00:16:56,758 --> 00:16:59,275
That's strong yet flexible.
282
00:16:59,275 --> 00:17:04,206
An automated saw cuts the bars
To a length of 35 inches.
283
00:17:04,206 --> 00:17:10,034
The bar will be stretched and
Shortened as it's transformed.
284
00:17:10,034 --> 00:17:13,862
A forge heats and hammers
The hilt end to a round shape,
285
00:17:13,862 --> 00:17:17,448
Leaving the rest of the rod
Rectangular.
286
00:17:17,448 --> 00:17:21,103
Here you can see the difference
In the rod's shape.
287
00:17:21,103 --> 00:17:24,482
Another forging machine
Softens the end of the rod
288
00:17:24,482 --> 00:17:27,862
And pushes the blade
Through a series of hammers.
289
00:17:27,862 --> 00:17:30,655
This tapers the blade
And stretches the steel,
290
00:17:30,655 --> 00:17:32,620
Doubling it in size.
291
00:17:35,137 --> 00:17:38,379
An operator clamps
The tapered blade in a jig
292
00:17:38,379 --> 00:17:41,275
To hold it straight
While the steel cools.
293
00:17:43,931 --> 00:17:48,172
Then the operator slices
The hilt end to length.
294
00:17:48,172 --> 00:17:53,344
The excess steel will be
Recycled into new swords.
295
00:17:53,344 --> 00:17:57,724
Next, the blades are heated
In a 932-degree oven.
296
00:17:57,724 --> 00:17:59,482
This step removes stresses
297
00:17:59,482 --> 00:18:01,482
And makes the metal
Less brittle.
298
00:18:04,206 --> 00:18:05,896
After a second heating,
299
00:18:05,896 --> 00:18:08,793
The blades soak in oil
To cool and harden.
300
00:18:10,689 --> 00:18:13,827
The exposure to intense heat
Causes a rusty scale
301
00:18:13,827 --> 00:18:18,310
To form on the blade,
So technicians clean it off.
302
00:18:18,310 --> 00:18:22,034
A sword maker clamps the blades
In a disc grinder.
303
00:18:22,034 --> 00:18:26,310
The grinder carves a fine groove
From the hilt to the tip.
304
00:18:26,310 --> 00:18:30,931
The groove will house a wire
For the electric scoring system.
305
00:18:30,931 --> 00:18:32,344
The blade is cleaned to remove
306
00:18:32,344 --> 00:18:35,103
Any remaining
Surface imperfections.
307
00:18:35,103 --> 00:18:37,655
A spinning belt
Coated with an abrasive
308
00:18:37,655 --> 00:18:41,413
Grinds all four sides
Of the blade.
309
00:18:41,413 --> 00:18:43,206
Then the sword is polished
310
00:18:43,206 --> 00:18:46,068
Using a buffing wheel
And polishing compound.
311
00:18:49,275 --> 00:18:52,551
You can see the difference this
Makes in the blade on the right.
312
00:18:55,482 --> 00:18:58,206
The craftsman hammers the blade
Against an anvil
313
00:18:58,206 --> 00:19:01,482
To straighten out any kinks.
314
00:19:01,482 --> 00:19:03,482
Then he inspects the blade.
315
00:19:05,482 --> 00:19:07,931
If needed, the craftsman will
Make adjustments
316
00:19:07,931 --> 00:19:11,379
To the blade with a hammer.
317
00:19:11,379 --> 00:19:14,482
Now it's time to work
On the hilt end of the blade.
318
00:19:14,482 --> 00:19:18,310
Another craftsman locks the end
Of the blade in a threading die,
319
00:19:18,310 --> 00:19:19,793
Applies lubricant,
320
00:19:19,793 --> 00:19:22,793
And activates
The automated system.
321
00:19:22,793 --> 00:19:26,586
The system turns the sword
In the die, carving out threads.
322
00:19:26,586 --> 00:19:29,000
Then the threaded hilt
Is cut to length.
323
00:19:32,379 --> 00:19:35,655
At the next station,
A computerized laser engraves
324
00:19:35,655 --> 00:19:39,448
The company logo into the steel.
325
00:19:39,448 --> 00:19:41,448
After the sensor barrel
Is installed
326
00:19:41,448 --> 00:19:42,965
On the end of the sword
327
00:19:42,965 --> 00:19:46,241
And the electrical scoring wire
Is placed in the groove,
328
00:19:46,241 --> 00:19:50,551
The technician applies glue
To keep the wire secure.
329
00:19:50,551 --> 00:19:52,517
The sword blade is placed
In a rack
330
00:19:52,517 --> 00:19:55,586
That holds it
In a bow-like bend.
331
00:19:55,586 --> 00:19:57,310
This step will give
The glued wire
332
00:19:57,310 --> 00:19:59,034
The flexibility it needs
333
00:19:59,034 --> 00:20:02,344
To bend with the rest
Of the sword while in use.
334
00:20:02,344 --> 00:20:05,551
After the blade has cured,
A pressure sensor spring
335
00:20:05,551 --> 00:20:09,344
Is inserted into the barrel
And capped with a sensor button.
336
00:20:11,448 --> 00:20:15,206
The technician uses screws
To hold the components together.
337
00:20:17,517 --> 00:20:18,931
To assemble the hilt,
338
00:20:18,931 --> 00:20:22,103
The scoring wire is threaded
Through a hole in the guard
339
00:20:22,103 --> 00:20:25,862
So it can easily slide
Into place.
340
00:20:25,862 --> 00:20:28,862
Then the sensor wire
Is connected to a socket.
341
00:20:31,482 --> 00:20:34,551
The wiring assembly is covered
With a plastic pad
342
00:20:34,551 --> 00:20:36,862
That allows the socket
To protrude.
343
00:20:39,413 --> 00:20:41,310
Finally, the pistol-grip handle
344
00:20:41,310 --> 00:20:45,689
Is screwed into
The threaded end of the blade.
345
00:20:45,689 --> 00:20:50,344
This fencing foil is now ready
For testing.

The technician plugs the fencing
Foil into testing equipment,

00:20:53,931 --> 00:20:56,931
Then he places a one-pound
Weight on the sensor button
348
00:20:56,931 --> 00:21:00,862
And checks to see
If it responds.
349
00:21:00,862 --> 00:21:02,689
And the results are in.
350
00:21:02,689 --> 00:21:06,896
This fencing foil is now ready
To stand up to its competition.
