3
00:00:53,219 --> 00:00:56,221
Narrator: The first stock cars
were souped up family sedans.
4
00:00:56,223 --> 00:00:59,758
But today, they're custom built
for the racetrack.
5
00:00:59,760 --> 00:01:02,628
Each car body
must match the contours
6
00:01:02,630 --> 00:01:04,696
of templates set by Nascar,
7
00:01:04,698 --> 00:01:08,067
the national association
of stock car auto racing.
8
00:01:15,108 --> 00:01:17,543
On the racetrack,
the shape of a car
9
00:01:17,545 --> 00:01:20,913
can give it an aerodynamic edge
over the competition,
10
00:01:20,915 --> 00:01:26,051
so in Nascar races, car bodies
must have uniform curves.
11
00:01:26,053 --> 00:01:29,288
The regulations put the focus
on driver skill
12
00:01:29,290 --> 00:01:31,323
and make the race a fair one.
13
00:01:31,325 --> 00:01:34,460
They mold some
of the car's body parts
14
00:01:34,462 --> 00:01:36,628
from a carbon fiber
and kevlar material.
15
00:01:36,630 --> 00:01:40,732
First, a technician applies
a release agent to a mold
16
00:01:40,734 --> 00:01:42,668
for the car's front end.
17
00:01:42,670 --> 00:01:45,437
Then he sprays a paint undercoat
into it.
18
00:01:45,439 --> 00:01:50,742
This undercoat will eventually
transfer to the completed panel.
19
00:01:50,744 --> 00:01:55,347
A computerized cutter slices the
carbon fiber and kevlar fabric
20
00:01:55,349 --> 00:01:56,815
into strips.
21
00:01:59,252 --> 00:02:01,653
It produces 22 pieces,
22
00:02:01,655 --> 00:02:05,390
each one cut to fit
a different section of the mold.
23
00:02:05,392 --> 00:02:08,894
The technician rolls epoxy resin
onto the fabric
24
00:02:08,896 --> 00:02:10,429
one strip at a time.
25
00:02:10,431 --> 00:02:13,499
Once the strip
has been completely coated,
26
00:02:13,501 --> 00:02:15,501
he transfers it to the mold.
27
00:02:18,671 --> 00:02:21,340
He tucks the fabric
into the contours
28
00:02:21,342 --> 00:02:23,809
and smooths out
any big wrinkles.
29
00:02:25,345 --> 00:02:29,448
He layers the strips three deep
in a crisscross configuration
30
00:02:29,450 --> 00:02:32,317
for structural integrity.
31
00:02:32,319 --> 00:02:36,455
A co worker covers the carbon
fiber with perforated plastic.
32
00:02:38,892 --> 00:02:42,828
They add layers of absorbent
polyester and thick plastic,
33
00:02:42,830 --> 00:02:45,764
which they glue
to the edge of the mold.
34
00:02:45,766 --> 00:02:48,967
They insert a fitting
and connect a vacuum,
35
00:02:48,969 --> 00:02:52,604
which sucks out air
and excess epoxy resin.
36
00:02:52,606 --> 00:02:55,407
The polyester material
soaks up the resin
37
00:02:55,409 --> 00:02:59,111
as it flows through the holes
in the first plastic layer.
38
00:02:59,113 --> 00:03:03,615
This both smooths and compacts
the carbon fiber layers.
39
00:03:03,617 --> 00:03:07,252
Then it's into a hot oven
to bake for three hours.
40
00:03:07,254 --> 00:03:09,054
This activates the epoxy
41
00:03:09,056 --> 00:03:12,891
and combines the layers of
carbon fiber and kevlar fabric.
42
00:03:12,893 --> 00:03:16,428
An employee removes
the completed stock car panel
43
00:03:16,430 --> 00:03:17,696
and inspects it.
44
00:03:19,365 --> 00:03:21,833
Then it's over
to a weigh station.
45
00:03:21,835 --> 00:03:24,036
At just under 8 pounds,
46
00:03:24,038 --> 00:03:27,573
the part is lightweight
yet virtually shatterproof.
47
00:03:27,575 --> 00:03:29,675
Meanwhile, at another factory,
48
00:03:29,677 --> 00:03:32,311
work begins on
the stock car chassis.
49
00:03:32,313 --> 00:03:36,114
They build it from square steel
tubing that's super strong.
50
00:03:36,116 --> 00:03:38,550
An employee
welds the pieces together
51
00:03:38,552 --> 00:03:41,220
to create a support structure
for the car.
52
00:03:42,288 --> 00:03:43,889
At the next station,
53
00:03:43,891 --> 00:03:47,693
a worker forces narrow steel
tubing against a spiral bit
54
00:03:47,695 --> 00:03:49,695
to carve notches in it.
55
00:03:50,997 --> 00:03:53,532
This tubing
is for the roll cage,
56
00:03:53,534 --> 00:03:57,803
the structure that protects the
driver if there's an accident.
57
00:03:57,805 --> 00:04:01,540
The notches will help
form better joints.
58
00:04:01,542 --> 00:04:06,178
He grinds the rough edges,
creating a smooth surface
59
00:04:06,180 --> 00:04:09,114
to weld the tube
to the rest of the roll cage.
60
00:04:15,221 --> 00:04:18,624
Once complete, the team
transfers the roll cage
61
00:04:18,626 --> 00:04:21,860
to the main frame
of the chassis.
62
00:04:24,230 --> 00:04:27,432
They tack weld it
before doing the final welds.
63
00:04:31,771 --> 00:04:34,606
The next part
is called the rear clip.
64
00:04:34,608 --> 00:04:39,778
It holds the fuel tank and has
mounts for the rear suspension.
65
00:04:39,780 --> 00:04:42,848
With the car framework
now complete,
66
00:04:42,850 --> 00:04:46,351
a technician scans it
using a digital measuring probe.
67
00:04:46,353 --> 00:04:49,655
The scan confirms that
the dimensions are correct.
68
00:04:51,691 --> 00:04:54,059
They now assemble
the various steel
69
00:04:54,061 --> 00:04:57,529
and carbon fiber body parts
to the stock car framework.
70
00:05:01,934 --> 00:05:04,369
They measure
the completed car body
71
00:05:04,371 --> 00:05:06,738
by laying template grids on it.
72
00:05:06,740 --> 00:05:11,677
The biggest one sits
over the center of the car.
73
00:05:11,679 --> 00:05:14,012
They pull a gauge
through the gaps
74
00:05:14,014 --> 00:05:16,615
between the templates
and the car body.
75
00:05:18,451 --> 00:05:22,487
The gap cannot exceed
the tolerances set by Nascar.
76
00:05:22,489 --> 00:05:25,157
They often must tweak the shape
of a body part
77
00:05:25,159 --> 00:05:26,992
to meet regulations.
78
00:05:29,295 --> 00:05:31,229
Once the car has been painted,
79
00:05:31,231 --> 00:05:35,033
they apply headlight decals
where the real ones usually are.
80
00:05:35,035 --> 00:05:37,602
Real headlights
would add too much weight
81
00:05:37,604 --> 00:05:40,205
and pose a safety risk
if they shattered.
82
00:05:42,208 --> 00:05:45,210
It's taken three weeks
of intensive work,
83
00:05:45,212 --> 00:05:49,047
but this stock car body
is now ready for the mechanics.
84
00:05:49,049 --> 00:05:52,384
Things are about
to pick up speed.
85
00:06:00,493 --> 00:06:02,894
Narrator: The game of Hurling
has been played in Ireland
86
00:06:02,896 --> 00:06:05,063
for at least 2,000 years.
87
00:06:05,065 --> 00:06:07,733
Players swing a stick
called a Hurley
88
00:06:07,735 --> 00:06:11,903
to hit a ball the size
of a hockey puck into a net.
89
00:06:11,905 --> 00:06:14,139
Winning takes skill,
quick reflexes,
90
00:06:14,141 --> 00:06:16,675
and, of course,
the luck of the Irish.
91
00:06:20,179 --> 00:06:22,881
Pass the ball
and pass on the tradition.
92
00:06:22,883 --> 00:06:24,816
Hurling is a game that's older
93
00:06:24,818 --> 00:06:27,352
than the recorded history
of Ireland.
94
00:06:31,424 --> 00:06:35,227
In Ireland, Hurleys are still
made the old fashioned way
95
00:06:35,229 --> 00:06:37,496
by hand in small shops.
96
00:06:39,966 --> 00:06:42,501
Ash is the wood of choice.
97
00:06:42,503 --> 00:06:45,404
They use only the part
of the tree near the root
98
00:06:45,406 --> 00:06:48,340
because the grain flows
in a natural curve there,
99
00:06:48,342 --> 00:06:52,277
making the stick less likely
to break during play.
100
00:06:52,279 --> 00:06:54,913
The Hurley maker
slices the trunk
101
00:06:54,915 --> 00:06:57,749
into planks
that are one inch thick.
102
00:06:57,751 --> 00:07:01,720
He'll make one Hurley
from each plank.
103
00:07:03,055 --> 00:07:05,524
He stacks the planks
104
00:07:05,526 --> 00:07:08,860
and then picks through them
to select one for shaping.
105
00:07:13,666 --> 00:07:16,902
He scrutinizes the curve
of the grain on the boards.
106
00:07:16,904 --> 00:07:18,403
It needs to be suitable
107
00:07:18,405 --> 00:07:21,173
for the size of the Hurley
he'll be making.
108
00:07:22,608 --> 00:07:24,509
His selection made,
109
00:07:24,511 --> 00:07:27,345
he places a see through
plastic pattern on the board.
110
00:07:27,347 --> 00:07:31,183
The transparency allows him
to find the curve of the grain
111
00:07:31,185 --> 00:07:34,653
and position it within the
striking surface of the Hurley.
112
00:07:34,655 --> 00:07:38,056
He draws an outline around it
with a pencil.
113
00:07:40,393 --> 00:07:43,462
After a rough cut
and some initial shaping,
114
00:07:43,464 --> 00:07:47,098
he re pencils the pattern
and cuts it with a band saw.
115
00:07:52,438 --> 00:07:56,274
The striking surface
of the Hurley is called the bas.
116
00:07:56,276 --> 00:07:59,010
It's the most substantial part
of the stick.
117
00:08:01,781 --> 00:08:05,450
He sculpts the stick to various
thicknesses with a planer.
118
00:08:09,589 --> 00:08:13,391
He keeps it thick at the bas
and thins it at the stem
119
00:08:13,393 --> 00:08:15,460
to give the stick
some elasticity
120
00:08:15,462 --> 00:08:16,862
when striking the ball.
121
00:08:16,864 --> 00:08:20,398
This will allow the player
to hit the ball farther.
122
00:08:27,473 --> 00:08:31,142
He sands the edges
to make them more even.
123
00:08:31,144 --> 00:08:34,779
He tapers the bas
to the very end,
124
00:08:34,781 --> 00:08:37,816
creating a sloped surface so the
ball can be picked up easily.
125
00:08:41,687 --> 00:08:45,156
He then switches
to a finer grid abrasive belt
126
00:08:45,158 --> 00:08:47,659
and sands the handle
and the rest of the stick
127
00:08:47,661 --> 00:08:49,561
until it's super smooth.
128
00:08:51,931 --> 00:08:54,466
Next, he cuts steel banding
to a length
129
00:08:54,468 --> 00:08:57,903
that's a little more than
twice the diameter of the bas.
130
00:09:00,439 --> 00:09:03,408
He loops the band
around the end of the bas
131
00:09:03,410 --> 00:09:05,243
and clamps it snugly to it.
132
00:09:08,147 --> 00:09:11,283
He drives large nails
into the band to puncture it.
133
00:09:14,787 --> 00:09:17,389
He hammers smaller nails
into those holes
134
00:09:17,391 --> 00:09:19,491
and all the way
through the wood.
135
00:09:22,962 --> 00:09:26,231
He clips the protruding nails.
136
00:09:26,233 --> 00:09:30,468
He then flattens the cut ends
to turn the nails into rivets.
137
00:09:34,674 --> 00:09:36,875
He folds the ends
of the looped band together
138
00:09:36,877 --> 00:09:40,345
at the rim of the bas
and nails them to the wood.
139
00:09:43,549 --> 00:09:46,217
Now securely attached,
140
00:09:46,219 --> 00:09:48,186
the steel band
will reinforce the Hurley
141
00:09:48,188 --> 00:09:53,091
at its most vulnerable point
the end of the striking surface.
142
00:09:53,093 --> 00:09:56,127
Not every player
wants their Hurley banded.
143
00:09:56,129 --> 00:09:59,264
This is an optional feature.
144
00:09:59,266 --> 00:10:02,167
He now winds rubber tape
just under the handle
145
00:10:02,169 --> 00:10:03,468
for better gripping.
146
00:10:05,471 --> 00:10:08,807
He continues to twist it
partway down the stick
147
00:10:08,809 --> 00:10:12,711
because players sometimes
grip it there with both hands.
148
00:10:14,614 --> 00:10:18,016
He finishes the wrap at
both ends with electrical tape,
149
00:10:18,018 --> 00:10:20,385
which has stronger
adhesive backing.
150
00:10:20,387 --> 00:10:23,421
It will prevent unraveling
of the rubber tape.
151
00:10:26,626 --> 00:10:30,695
It's taken about 20 minutes
to craft this Hurley stick.
152
00:10:30,697 --> 00:10:33,832
How long it will last
is anyone's guess.
153
00:10:33,834 --> 00:10:36,067
There's no warranty on Hurleys,
154
00:10:36,069 --> 00:10:38,837
and it's sure to break
at some point
155
00:10:38,839 --> 00:10:41,773
because Hurling is a rough game.
156
00:10:41,775 --> 00:10:45,777
Some players go through
several Hurleys in one season.
157
00:10:48,981 --> 00:10:51,750
It doesn't matter
if you lose a stick
158
00:10:51,752 --> 00:10:53,718
as long as you win the game.
159
00:11:05,140 --> 00:11:06,574
Narrator:
In an audio system,
160
00:11:06,576 --> 00:11:09,110
the amplifier is the component
which makes the sound louder
161
00:11:09,112 --> 00:11:12,213
and sends it to the speakers.
162
00:11:12,215 --> 00:11:15,416
While most amps on the market
are powered by transistors,
163
00:11:15,418 --> 00:11:19,320
many audiophiles
swear by tube amplifiers,
164
00:11:19,322 --> 00:11:22,090
which use older
vacuum tube technology.
165
00:11:24,093 --> 00:11:26,861
[ Guitar notes play ]
166
00:11:28,530 --> 00:11:30,832
Many believe
that tube amplifiers
167
00:11:30,834 --> 00:11:34,602
produce a warmer,
more natural sound.
168
00:11:34,604 --> 00:11:37,038
This factory makes the amp's
main chassis
169
00:11:37,040 --> 00:11:39,440
from a sheet
of polished stainless steel.
170
00:11:39,442 --> 00:11:41,876
A computer guided punch press
171
00:11:41,878 --> 00:11:44,912
cuts openings for the
power switches, control knobs,
172
00:11:44,914 --> 00:11:46,414
and other components.
173
00:11:46,416 --> 00:11:49,784
The press prepares eight chassis
per sheet.
174
00:11:49,786 --> 00:11:53,788
Workers separate them
with a few strikes of a mallet.
175
00:11:53,790 --> 00:11:55,990
Then they place them
one at a time
176
00:11:55,992 --> 00:11:59,327
in a bending machine
called a press break.
177
00:11:59,329 --> 00:12:02,864
Once they position the sheet
with the help of metal guides,
178
00:12:02,866 --> 00:12:04,665
they activate a foot pedal,
179
00:12:04,667 --> 00:12:08,536
releasing 90 tons of pressure
to bend the edge of the sheet.
180
00:12:11,140 --> 00:12:13,207
Then they remove
the adhesive film
181
00:12:13,209 --> 00:12:16,077
which has been protecting
the mirror finish surface
182
00:12:16,079 --> 00:12:17,512
of the chassis.
183
00:12:17,514 --> 00:12:21,382
They clean off any remaining
adhesive residue with alcohol.
184
00:12:22,885 --> 00:12:26,721
Then they put the chassis
into an offset press.
185
00:12:26,723 --> 00:12:29,524
Using a silk screen
printing process,
186
00:12:29,526 --> 00:12:32,226
it labels the controls
and connections.
187
00:12:34,530 --> 00:12:36,531
Next are the speaker terminals,
188
00:12:36,533 --> 00:12:39,433
which connect the speaker wires
to the amp.
189
00:12:39,435 --> 00:12:42,770
These connectors are made
of gold plated brass,
190
00:12:42,772 --> 00:12:44,772
which are nonmagnetic metals.
191
00:12:44,774 --> 00:12:47,675
Magnetic ones would react
to the electric current
192
00:12:47,677 --> 00:12:50,378
and cause distortion.
193
00:12:50,380 --> 00:12:53,281
The terminal's circuit board,
installed next,
194
00:12:53,283 --> 00:12:56,317
carries the amplified signal
from the main circuit board
195
00:12:56,319 --> 00:12:58,419
to the speaker terminals.
196
00:12:58,421 --> 00:13:00,922
They install and connect
the power switch
197
00:13:00,924 --> 00:13:04,158
and the circuit board for
the vacuum tube illumination.
198
00:13:04,160 --> 00:13:07,161
This indicates
the tube's status.
199
00:13:09,464 --> 00:13:12,500
Meanwhile, this machine
winds strands of copper wire
200
00:13:12,502 --> 00:13:14,235
around plastic bobbins
201
00:13:14,237 --> 00:13:17,772
to begin making the amp's
output transformers.
202
00:13:17,774 --> 00:13:20,975
Output transformers
match the amp's circuitry
203
00:13:20,977 --> 00:13:25,279
to the electronic specifications
of different types of speakers.
204
00:13:25,281 --> 00:13:28,182
The number of wires,
their different gauges,
205
00:13:28,184 --> 00:13:31,219
and the number of revolutions
around the bobbin
206
00:13:31,221 --> 00:13:34,255
create this unique
compatibility.
207
00:13:34,257 --> 00:13:37,325
After taping the wires
to prevent unraveling,
208
00:13:37,327 --> 00:13:41,262
they join, then solder the ends
to additional wiring.
209
00:13:41,264 --> 00:13:43,864
They will later connect
to the amp's main board.
210
00:13:43,866 --> 00:13:47,935
A fiberglass sleeve
insulates the connection.
211
00:13:47,937 --> 00:13:51,405
They place the bobbin
in a lamination machine.
212
00:13:51,407 --> 00:13:54,775
Laminations are thin plates
of carbon steel.
213
00:13:54,777 --> 00:13:58,779
The machine stacks them
all around the bobbin.
214
00:13:58,781 --> 00:14:03,217
Then workers put a bolt in each
corner to hold them together.
215
00:14:07,322 --> 00:14:11,325
They place the laminated bobbin
in an aluminum housing
216
00:14:11,327 --> 00:14:14,428
and pour in hot black tar.
217
00:14:14,430 --> 00:14:17,765
This immobilizes the laminations
so they won't rattle
218
00:14:17,767 --> 00:14:21,535
when the amp is amplifying
low frequencies.
219
00:14:21,537 --> 00:14:24,639
Then workers install
the two output transformers
220
00:14:24,641 --> 00:14:26,540
into the chassis,
221
00:14:26,542 --> 00:14:30,044
along with a third transformer
to power the amp.
222
00:14:32,147 --> 00:14:34,649
They take the amp's
main circuit board,
223
00:14:34,651 --> 00:14:37,585
plug in ceramic sockets
for the vacuum tubes...
224
00:14:40,188 --> 00:14:43,257
...and solder the sockets' leads
to the board.
225
00:14:45,360 --> 00:14:48,129
Then, after feeding
the transformer leads,
226
00:14:48,131 --> 00:14:50,831
they mount the main board
in the chassis,
227
00:14:50,833 --> 00:14:54,669
screwing it to posts
to hold it in place.
228
00:14:54,671 --> 00:14:58,072
Then they connect
the transformer leads.
229
00:15:05,414 --> 00:15:09,684
They plug the vacuum tubes
one by one into the sockets.
230
00:15:09,686 --> 00:15:13,988
The tubes are made of glass
with a heat resistant base.
231
00:15:13,990 --> 00:15:17,158
The interior contains
a combination of metals
232
00:15:17,160 --> 00:15:21,062
but no air,
hence the term vacuum tube.
233
00:15:21,064 --> 00:15:22,997
The amp has 11 tubes in all
234
00:15:22,999 --> 00:15:25,666
seven small ones
to power input signals
235
00:15:25,668 --> 00:15:28,836
from a source
such as a cd player
236
00:15:28,838 --> 00:15:32,540
and four big ones
to power output to the speakers.
237
00:15:35,911 --> 00:15:38,879
Then they attach the chassis'
ventilated bottom cover
238
00:15:38,881 --> 00:15:42,049
made of painted steel.
239
00:15:42,051 --> 00:15:43,217
They affix decals
240
00:15:43,219 --> 00:15:45,786
to differentiate
the output transformers
241
00:15:45,788 --> 00:15:47,788
from the power transformer.
242
00:15:50,125 --> 00:15:53,260
L.E.D. Lights turn green
when the amp is powered up
243
00:15:53,262 --> 00:15:56,397
and ready to deliver
that warm, natural sound
244
00:15:56,399 --> 00:15:59,633
that many believe
only traditional vacuum tubes
245
00:15:59,635 --> 00:16:01,469
can produce.
246
00:16:12,414 --> 00:16:15,983
Narrator: People generally like
their coffee either hot or iced,
247
00:16:15,985 --> 00:16:19,353
hence the need
for the thermal coffee pot.
248
00:16:19,355 --> 00:16:22,590
Pour in hot coffee,
and the pot holds in heat,
249
00:16:22,592 --> 00:16:24,725
keeping the coffee
at that temperature
250
00:16:24,727 --> 00:16:26,694
for a good half hour.
251
00:16:32,467 --> 00:16:36,170
The trick to a thermal coffee
pot is in the construction.
252
00:16:36,172 --> 00:16:38,973
Both the body and lid
have a double wall,
253
00:16:38,975 --> 00:16:41,008
two layers of stainless steel.
254
00:16:41,010 --> 00:16:44,745
Between them is a tiny gap
just 5 to 6 millimeters.
255
00:16:44,747 --> 00:16:48,115
The air in this gap
insulates the inner wall,
256
00:16:48,117 --> 00:16:50,618
trapping the heat
inside the pot.
257
00:16:52,020 --> 00:16:55,089
They start with
a stainless steel sheet
258
00:16:55,091 --> 00:16:57,324
just 1.2 millimeters thick.
259
00:16:57,326 --> 00:17:00,528
The first step is to cut it
into smaller pieces
260
00:17:00,530 --> 00:17:02,062
on a mechanical press.
261
00:17:02,064 --> 00:17:06,133
To make the coffee pot's body,
they cut it into strips,
262
00:17:06,135 --> 00:17:11,605
then each strip into squares
measuring 8x8 inches.
263
00:17:11,607 --> 00:17:14,775
Then they put each square
in another mechanical press.
264
00:17:14,777 --> 00:17:18,045
It stamps the square
onto a circular die,
265
00:17:18,047 --> 00:17:20,047
which cuts it into a disk.
266
00:17:20,049 --> 00:17:23,651
They'll now use this disk
to make the outer wall.
267
00:17:23,653 --> 00:17:26,420
They run the disk
through a lubricator
268
00:17:26,422 --> 00:17:30,090
that coats the surface with oil
to aid the next step
269
00:17:30,092 --> 00:17:34,228
on a machine called
a hydraulic deep drawing press.
270
00:17:34,230 --> 00:17:36,897
The machine's molders
draw the flat disk
271
00:17:36,899 --> 00:17:38,866
into a three dimensional shape.
272
00:17:38,868 --> 00:17:41,569
This stretches
the stainless steel fibers
273
00:17:41,571 --> 00:17:44,638
to a very fragile state.
274
00:17:44,640 --> 00:17:46,073
They strengthen the piece
275
00:17:46,075 --> 00:17:48,409
by what's called
thermic normalization,
276
00:17:48,411 --> 00:17:51,779
heating the metal
to 1,800 degrees fahrenheit,
277
00:17:51,781 --> 00:17:55,416
then letting it cool
to room temperature.
278
00:17:55,418 --> 00:17:59,053
This process restores
the original molecular structure
279
00:17:59,055 --> 00:18:00,621
of the stainless steel
280
00:18:00,623 --> 00:18:04,024
so it can be shaped further
without breaking.
281
00:18:04,026 --> 00:18:08,028
But first, they even out
the jagged rim with a trimmer.
282
00:18:13,802 --> 00:18:17,271
Then they return the wall
to the deep drawing press
283
00:18:17,273 --> 00:18:20,307
outfitted with
a differently shaped molder.
284
00:18:20,309 --> 00:18:24,578
The second drawing tapers
the wall to a more rounded shape
285
00:18:24,580 --> 00:18:29,316
and forms a base to make
the bottom perfectly flat.
286
00:18:29,318 --> 00:18:31,085
Then it's back to the trimmer,
287
00:18:31,087 --> 00:18:34,588
outfitted with a different tool
this time, to smooth the rim.
288
00:18:38,460 --> 00:18:40,261
They repeat the same steps
289
00:18:40,263 --> 00:18:42,863
to make the coffee pot's
inner wall.
290
00:18:42,865 --> 00:18:46,367
The deep drawing press
pulls the stainless steel disk
291
00:18:46,369 --> 00:18:48,402
into a slightly different shape
292
00:18:48,404 --> 00:18:51,639
with a lip protruding
to one side.
293
00:18:57,178 --> 00:18:59,413
They heat the wall
in the induction oven
294
00:18:59,415 --> 00:19:01,382
to restore
the molecular structure
295
00:19:01,384 --> 00:19:02,917
before shaping the metal
further.
296
00:19:05,720 --> 00:19:09,089
Then they place the wall
in a mold and release a press.
297
00:19:13,962 --> 00:19:17,598
This shapes the protruding lip
into a spout.
298
00:19:20,068 --> 00:19:22,836
Then they transfer the wall
to another press,
299
00:19:22,838 --> 00:19:26,040
which stamps it with a die,
cutting off excess metal.
300
00:19:28,510 --> 00:19:31,612
They check to make sure
that the inner and outer walls
301
00:19:31,614 --> 00:19:33,180
fit together properly.
302
00:19:33,182 --> 00:19:34,782
If everything is fine,
303
00:19:34,784 --> 00:19:38,252
they Polish both walls
inside and out.
304
00:19:38,254 --> 00:19:39,553
A little polishing paste
305
00:19:39,555 --> 00:19:42,122
applied with a sisal brush
on the polishing wheel
306
00:19:42,124 --> 00:19:44,858
has the surfaces glistening
in no time.
307
00:19:44,860 --> 00:19:49,129
The surface is now perfectly
smooth and ready for welding.
308
00:19:51,099 --> 00:19:52,533
The first part they weld
309
00:19:52,535 --> 00:19:55,135
is the coffee pot's
stainless steel handle.
310
00:19:55,137 --> 00:19:58,138
They shape it with two strikes
of a press, then Polish.
311
00:20:01,109 --> 00:20:02,643
They use a spot welder
312
00:20:02,645 --> 00:20:05,613
to fuse the handle
to the pot's outer wall.
313
00:20:08,683 --> 00:20:11,552
Then they turn the wall
upside down
314
00:20:11,554 --> 00:20:14,788
to stamp the manufacturer's logo
into the bottom.
315
00:20:17,158 --> 00:20:19,293
Now the assembly.
316
00:20:19,295 --> 00:20:21,895
They place the inner wall
on a fixture,
317
00:20:21,897 --> 00:20:23,697
then the outer wall over it.
318
00:20:23,699 --> 00:20:28,369
A press pushes the inner
to the correct depth.
319
00:20:28,371 --> 00:20:30,604
Then they weld along the rim
of the outer wall,
320
00:20:30,606 --> 00:20:33,073
fusing it to the inner one.
321
00:20:35,377 --> 00:20:39,279
The coffee pot's lid also
has double walls for insulation.
322
00:20:39,281 --> 00:20:41,415
They weld a hinged lever
to the lid
323
00:20:41,417 --> 00:20:44,752
and the adjoining part of the
hinge to the coffee pot body.
324
00:20:47,722 --> 00:20:50,624
Then they gently hammer a pin
through the hinge,
325
00:20:50,626 --> 00:20:54,428
riveting the ends of the pin
so that it can't fall out.
326
00:20:57,932 --> 00:21:01,702
After a thorough cleaning
in a dishwasher,
327
00:21:01,704 --> 00:21:04,672
the coffee pot is ready to use.
328
00:21:15,250 --> 00:21:17,618
