1
00:00:53,387 --> 00:00:55,954
In the first half of the 20th century,
2
00:00:55,956 --> 00:00:58,190
power steering
was not an option.
3
00:00:58,192 --> 00:01:01,093
Prototypes were too expensive
for production.
4
00:01:01,095 --> 00:01:04,163
During world war ii,
the british and american armies
5
00:01:04,165 --> 00:01:05,764
began to use power steering
6
00:01:05,766 --> 00:01:08,400
in heavy vehicles
like armored cars,
7
00:01:08,402 --> 00:01:11,970
and auto makers soon began
adding it to passenger vehicles.
8
00:01:14,508 --> 00:01:16,208
These hydraulic steering pumps
9
00:01:16,210 --> 00:01:18,911
are the steering muscle
in muscle cars,
10
00:01:18,913 --> 00:01:22,714
providing a power assist
to give the driver more control.
11
00:01:24,919 --> 00:01:28,654
Using computer software,
manufacturers design the pumps
12
00:01:28,656 --> 00:01:31,523
to fit specific
classes of vehicles.
13
00:01:31,525 --> 00:01:34,927
They print a plastic model
using a 3-d printer.
14
00:01:34,929 --> 00:01:38,263
This is a time-lapse
video of the process.
15
00:01:38,265 --> 00:01:41,500
The designer removes the
plastic model and he sends it,
16
00:01:41,502 --> 00:01:44,837
along with the computer design,
to a casting facility,
17
00:01:44,839 --> 00:01:49,041
which produces aluminum
pump-housing parts.
18
00:01:49,043 --> 00:01:51,243
Back at the factory,
a worker mounts
19
00:01:51,245 --> 00:01:53,245
12 of the castings in a machine
20
00:01:53,247 --> 00:01:55,314
with computer-controlled
tooling.
21
00:01:57,618 --> 00:01:59,218
He activates the system,
22
00:01:59,220 --> 00:02:03,555
and it moves the rack
of castings into position.
23
00:02:03,557 --> 00:02:07,159
The tools machine
the face of the castings.
24
00:02:07,161 --> 00:02:09,428
They bore center-bearing holes
and drill
25
00:02:09,430 --> 00:02:13,365
threaded holes for bolts.
26
00:02:13,367 --> 00:02:16,635
This is precision work,
which will now be double-checked
27
00:02:16,637 --> 00:02:21,306
by a device known as
a coordinate measuring machine.
28
00:02:21,308 --> 00:02:24,743
A worker clamps the pump
housing in the machine.
29
00:02:24,745 --> 00:02:28,847
Then, a ruby-tipped probe
scans its dimensions.
30
00:02:28,849 --> 00:02:31,483
The machine analyzes
the information.
31
00:02:31,485 --> 00:02:34,052
It verifies that every part
of the housing meets
32
00:02:34,054 --> 00:02:36,155
the precise specifications.
33
00:02:40,661 --> 00:02:45,497
with that confirmation,
he unclamps the part.
34
00:02:45,499 --> 00:02:48,867
This is the pump housing in the
various stages of production.
35
00:02:52,540 --> 00:02:55,007
other tools turn a solid
aluminum dowel
36
00:02:55,009 --> 00:02:58,143
into a fitting for
the pump's pressure bore.
37
00:02:58,145 --> 00:02:59,912
They sculpt the circumference
38
00:02:59,914 --> 00:03:02,948
and carve a complex
geometry in the center
39
00:03:02,950 --> 00:03:07,452
for controlling the flow
of power steering fluid.
40
00:03:07,454 --> 00:03:10,222
Another tool carves the thread
to screw the fitting
41
00:03:10,224 --> 00:03:11,690
into the pressure bore,
42
00:03:11,692 --> 00:03:15,627
and the final one drills
the fluid bypass hole.
43
00:03:15,629 --> 00:03:19,565
A blue anodized coating
protects it from corrosion.
44
00:03:19,567 --> 00:03:23,468
A worker now locks the pump
housing in a honing machine.
45
00:03:23,470 --> 00:03:26,805
The machine floods the pressure
relief bore with lubricant
46
00:03:26,807 --> 00:03:32,077
as the stone hones the inner
diameter to a precise tolerance.
47
00:03:32,079 --> 00:03:35,647
He then transfers the pump
housing to a press.
48
00:03:35,649 --> 00:03:39,551
He inserts a bearing and shaft
in the center bore.
49
00:03:39,553 --> 00:03:42,955
He places an aluminum tool
over the bearing and shaft
50
00:03:42,957 --> 00:03:44,590
to align them correctly
51
00:03:44,592 --> 00:03:48,594
as he manually presses
them into the bore.
52
00:03:48,596 --> 00:03:51,196
Once the bearing has been
solidly entrenched,
53
00:03:51,198 --> 00:03:53,432
he removes the tool.
54
00:03:53,434 --> 00:03:56,101
He inserts a metal
snap ring in a groove
55
00:03:56,103 --> 00:04:00,038
to retain the bearing and shaft.
56
00:04:00,040 --> 00:04:03,742
He turns the power steering pump
over an installs o-rings
57
00:04:03,744 --> 00:04:05,677
to seal the pressure section.
58
00:04:09,383 --> 00:04:11,917
then the worker
installs the cam ring
59
00:04:11,919 --> 00:04:15,687
and the rotor with the veins.
60
00:04:15,689 --> 00:04:19,024
As the rotor spins,
the veins will move in and out,
61
00:04:19,026 --> 00:04:20,626
collecting hydraulic fluid.
62
00:04:20,628 --> 00:04:22,527
This process adds pressure,
63
00:04:22,529 --> 00:04:25,397
taking the load off
the steering wheel.
64
00:04:25,399 --> 00:04:28,033
The worker installs
this critical sub-assembly
65
00:04:28,035 --> 00:04:31,470
in the pump housing.
66
00:04:31,472 --> 00:04:34,606
He screws the device in place
in the four corners.
67
00:04:38,445 --> 00:04:40,679
he turns the power
steering pump over
68
00:04:40,681 --> 00:04:42,714
and seals the end
of the pressure bore
69
00:04:42,716 --> 00:04:45,517
with an aluminum plug
and copper washer.
70
00:04:51,525 --> 00:04:53,525
he now tucks the pressure
relief valve
71
00:04:53,527 --> 00:04:57,663
in the open part
of the pressure bore.
72
00:04:57,665 --> 00:04:59,831
He secures it with the special
flow fitting
73
00:04:59,833 --> 00:05:02,100
we saw machined earlier on.
74
00:05:06,540 --> 00:05:09,074
he tightens the fitting
with a torque wrench.
75
00:05:11,545 --> 00:05:14,646
He turns the power
steering pump onto its side.
76
00:05:16,717 --> 00:05:18,950
He attaches a fitting
to the intake port
77
00:05:18,952 --> 00:05:20,919
for the hydraulic fluid.
78
00:05:20,921 --> 00:05:22,954
The power steering pump
is now equipped
79
00:05:22,956 --> 00:05:24,823
with all the working parts.
80
00:05:27,428 --> 00:05:29,928
Here's a look at
the transformation.
81
00:05:29,930 --> 00:05:33,465
A display model with a cutout
offers a peak inside.
82
00:05:35,502 --> 00:05:36,735
At the test station,
83
00:05:36,737 --> 00:05:38,937
a technician makes
all the connections
84
00:05:38,939 --> 00:05:42,541
and runs it as if it was
in an actual racecar.
85
00:05:42,543 --> 00:05:45,544
A computer measures its
performance and confirms
86
00:05:45,546 --> 00:05:49,648
that it meets all
the technical requirements.
87
00:05:49,650 --> 00:05:52,484
The power steering pump
is now ready for the twists
88
00:05:52,486 --> 00:05:55,053
and turns of
professional racing.
89
00:06:11,305 --> 00:06:13,372
narrator: Across asia,
rice bowl meals
90
00:06:13,374 --> 00:06:15,407
are an enduring tradition.
91
00:06:15,409 --> 00:06:17,776
By combining protein
and vegetable elements
92
00:06:17,778 --> 00:06:20,746
with rice in a bowl,
people have a meal.
93
00:06:20,748 --> 00:06:22,447
It's asian comfort food,
94
00:06:22,449 --> 00:06:25,083
and somehow it just tastes
better in a bowl.
95
00:06:25,085 --> 00:06:27,252
And people around the world
are discovering
96
00:06:27,254 --> 00:06:29,955
the appeal of these
one-bowl meals.
97
00:06:32,259 --> 00:06:35,060
Asian bowl meals
start with the rice.
98
00:06:35,062 --> 00:06:38,230
Then people add
whatever they want.
99
00:06:38,232 --> 00:06:42,067
At food bars like this,
there's any number of choices.
100
00:06:42,069 --> 00:06:45,704
The bowls can be served up fast,
and the food is healthy.
101
00:06:45,706 --> 00:06:48,507
Because there are many
possible combinations,
102
00:06:48,509 --> 00:06:52,010
these one-bowl meals
never get boring.
103
00:06:52,012 --> 00:06:54,679
Preparations start
with the rice.
104
00:06:54,681 --> 00:06:58,784
This food worker measures
enough for 40 portions.
105
00:06:58,786 --> 00:07:01,119
After rinsing the grains
repeatedly,
106
00:07:01,121 --> 00:07:04,322
he adds it to a rice cooker.
107
00:07:04,324 --> 00:07:08,260
He then measures the water
for cooking.
108
00:07:08,262 --> 00:07:10,262
He adds it to the cooker.
109
00:07:10,264 --> 00:07:15,167
It will steam the grains so they
cook uniformly for one hour.
110
00:07:15,169 --> 00:07:17,569
While the rice is cooking,
the food worker
111
00:07:17,571 --> 00:07:21,406
then pours peeled garlic cloves
into a food processor.
112
00:07:23,377 --> 00:07:25,877
He adds a half cup
of vegetable oil.
113
00:07:25,879 --> 00:07:29,581
The garlic will flavor several
dishes in the asian food bar.
114
00:07:32,186 --> 00:07:37,255
The food processor chops the
garlic to a fine consistency.
115
00:07:37,257 --> 00:07:39,591
Using a mandolin
vegetable slicer,
116
00:07:39,593 --> 00:07:43,228
he slices slivers of carrots.
117
00:07:43,230 --> 00:07:44,830
Along with chopped onions,
118
00:07:44,832 --> 00:07:48,366
the carrots will enhance
the flavor of fried rice.
119
00:07:48,368 --> 00:07:50,635
He now removes some rice
from the cooker,
120
00:07:50,637 --> 00:07:52,838
in order to make fried rice.
121
00:07:52,840 --> 00:07:56,475
He separates the grains
so they'll fry more uniformly.
122
00:08:00,013 --> 00:08:02,514
the food worker
is now ready to fry.
123
00:08:02,516 --> 00:08:05,750
He heats the wok
to a very high temperature.
124
00:08:05,752 --> 00:08:10,288
He adds cooking oil,
and it starts to sizzle.
125
00:08:10,290 --> 00:08:12,357
He tosses in the carrot slivers,
126
00:08:12,359 --> 00:08:15,827
chopped onion, garlic
and frozen peas.
127
00:08:15,829 --> 00:08:18,263
He constantly stirs
the ingredients,
128
00:08:18,265 --> 00:08:22,334
and the flavors
sweeten and deepen.
129
00:08:22,336 --> 00:08:25,604
He turns down the heat
a bit an adds the rice.
130
00:08:25,606 --> 00:08:28,740
He mixes the rice with the other
ingredients as the cooking
131
00:08:28,742 --> 00:08:33,211
continues at
a slightly lower temperature.
132
00:08:33,213 --> 00:08:35,013
He measures the temperature.
133
00:08:35,015 --> 00:08:36,481
For food safety reasons,
134
00:08:36,483 --> 00:08:41,186
it needs to be over
143 degrees fahrenheit.
135
00:08:41,188 --> 00:08:44,523
The food worker pours soy sauce
onto the hot wok.
136
00:08:44,525 --> 00:08:46,691
It trickles down
to permeate the rice,
137
00:08:46,693 --> 00:08:49,060
adding flavor and color.
138
00:08:49,062 --> 00:08:53,331
That completes the fried rice
component of the food bar.
139
00:08:53,333 --> 00:08:56,334
Next up are the vegetable
and protein choices.
140
00:08:58,105 --> 00:09:01,239
The food worker cubes
sushi-grade tuna.
141
00:09:01,241 --> 00:09:04,643
It will be marinated
with a spicy saucy shortly.
142
00:09:04,645 --> 00:09:07,279
He places the tuna
in a food bar container.
143
00:09:09,349 --> 00:09:12,350
He peels cucumber
and then juliennes it.
144
00:09:12,352 --> 00:09:14,553
The cucumber will be a raw
food choice
145
00:09:14,555 --> 00:09:17,455
that will offset
the strong flavor of the tuna.
146
00:09:19,693 --> 00:09:23,762
The food worker then prepares
the tuna's spicy marinade.
147
00:09:23,764 --> 00:09:25,297
He adds chili sauce
148
00:09:25,299 --> 00:09:30,268
and a smaller amount
of chili oil to mayonnaise.
149
00:09:30,270 --> 00:09:32,237
It's hot stuff.
150
00:09:35,309 --> 00:09:38,343
a seaweed salad dish
is another refreshing choice
151
00:09:38,345 --> 00:09:41,146
that will cool the palate.
152
00:09:41,148 --> 00:09:45,417
He adds the chili
mayonnaise to the tuna.
153
00:09:45,419 --> 00:09:47,152
And he turns up the heat
a little more
154
00:09:47,154 --> 00:09:49,287
with some extra chili oil.
155
00:09:52,192 --> 00:09:55,527
A thorough mixing completely
saturates the raw fish
156
00:09:55,529 --> 00:09:58,630
with the spicy sauce.
157
00:09:58,632 --> 00:10:00,999
Next, the food worker
prepares the dressing
158
00:10:01,001 --> 00:10:02,801
for a cabbage salad.
159
00:10:02,803 --> 00:10:05,437
He starts with
a white miso paste.
160
00:10:05,439 --> 00:10:08,540
A generous amount
of soy sauce follows.
161
00:10:08,542 --> 00:10:13,011
Sushi vinegar and vegetable oil
are the next ingredients.
162
00:10:13,013 --> 00:10:17,882
After adding some sesame oil,
he blends all the components.
163
00:10:17,884 --> 00:10:21,519
He coats the shredded cabbage
with the miso dressing.
164
00:10:21,521 --> 00:10:25,190
He sprinkles black sesame seeds
onto the cabbage salad.
165
00:10:27,995 --> 00:10:31,730
Teriyaki beef
is the next option.
166
00:10:31,732 --> 00:10:35,367
The main ingredients are shaved
filet steak, chopped ginger,
167
00:10:35,369 --> 00:10:37,202
and shredded onion.
168
00:10:37,204 --> 00:10:39,671
The food worker sautés the onion
and ginger
169
00:10:39,673 --> 00:10:42,907
to provide a flavor base.
170
00:10:42,909 --> 00:10:45,977
He adds the shaved steak,
and as it cooks,
171
00:10:45,979 --> 00:10:48,847
it takes up the essence
of the onion and ginger.
172
00:10:53,453 --> 00:10:55,186
the soy-based teriyaki sauce
173
00:10:55,188 --> 00:10:57,789
provides
the final layer of flavor.
174
00:11:00,460 --> 00:11:04,462
With this dish now complete,
it's time for the fun part --
175
00:11:04,464 --> 00:11:08,166
mixing and matching components
for the asian food bowl.
176
00:11:23,650 --> 00:11:26,217
Narrator: There was a time
when an elegant walking cane
177
00:11:26,219 --> 00:11:29,054
was a status symbol
for fashionable gentlemen.
178
00:11:29,056 --> 00:11:32,557
Today, a cane is no longer
considered an accessory,
179
00:11:32,559 --> 00:11:35,093
but rather a utilitarian
medical aid
180
00:11:35,095 --> 00:11:37,195
for people with mobility issues.
181
00:11:37,197 --> 00:11:39,631
However, one can
still find canes
182
00:11:39,633 --> 00:11:42,167
which combine both
function and fashion.
183
00:11:43,670 --> 00:11:46,571
Walking canes can indeed
be stylish,
184
00:11:46,573 --> 00:11:50,475
with straight or crook handles
made of exotic wood or bone,
185
00:11:50,477 --> 00:11:54,713
elegant knob handles,
or elaborate figurative handles.
186
00:11:54,715 --> 00:11:57,048
This family enterprise
has been hand-crafting
187
00:11:57,050 --> 00:12:02,153
walking canes since 1909.
188
00:12:02,155 --> 00:12:06,024
Making a crook handle requires
bending the handle material.
189
00:12:06,026 --> 00:12:09,094
After heating a curved steel
form in a fire,
190
00:12:09,096 --> 00:12:12,731
workers insert a square stick
of ebony in a steel spring
191
00:12:12,733 --> 00:12:16,201
and mount it on the central
axis of the machine.
192
00:12:16,203 --> 00:12:19,337
The clamp the machine's
guide wheel against the form,
193
00:12:19,339 --> 00:12:22,607
then clamp the part of the stick
that will remain straight.
194
00:12:25,779 --> 00:12:27,412
Using their body weight,
195
00:12:27,414 --> 00:12:30,248
the worker forces the
machine's lever forward,
196
00:12:30,250 --> 00:12:31,816
wrapping the top part
of the stick
197
00:12:31,818 --> 00:12:34,085
around the hot,
curved form.
198
00:12:39,025 --> 00:12:41,993
it's critical to do this slowly
to prevent the wood
199
00:12:41,995 --> 00:12:44,529
from snapping.
200
00:12:46,933 --> 00:12:50,869
Workers then lock the bent stick
against the form with a brace...
201
00:12:53,874 --> 00:12:55,874
And remove it from the machine.
202
00:13:00,881 --> 00:13:04,983
they set it aside for a week.
203
00:13:04,985 --> 00:13:08,253
One week later, they remove
the brace and spring
204
00:13:08,255 --> 00:13:10,955
and mount the curved
stick on a lathe.
205
00:13:10,957 --> 00:13:14,626
As the stick spins,
a carriage moves a saw down
206
00:13:14,628 --> 00:13:18,062
the straight part of the cane,
known as the shaft,
207
00:13:18,064 --> 00:13:20,999
reducing the diameter
and rounding it out.
208
00:13:23,170 --> 00:13:26,337
This is the shaft before
and after this step.
209
00:13:33,880 --> 00:13:36,815
a worker runs the handle
against a coarse grit
210
00:13:36,817 --> 00:13:40,785
sanding belt to pare it down
and begin rounding it out.
211
00:13:43,623 --> 00:13:47,125
He uses a router to refine
the shape and works on the
212
00:13:47,127 --> 00:13:50,128
harder-to-access inner
part of the curve.
213
00:13:54,100 --> 00:13:55,834
once the handle is rounded,
214
00:13:55,836 --> 00:13:58,469
and its diameter equal
to that of the shaft,
215
00:13:58,471 --> 00:14:01,005
he performs
a final fine sanding.
216
00:14:11,685 --> 00:14:15,653
then he polishes the entire cane
with polishing compound
217
00:14:15,655 --> 00:14:17,989
against a cotton buffing wheel.
218
00:14:22,929 --> 00:14:27,432
slowly but surely, this makes
the ebony sleek and lustrous.
219
00:14:31,938 --> 00:14:34,839
all wooden canes --
these here are made of maple --
220
00:14:34,841 --> 00:14:38,309
warp a bit during woodworking.
221
00:14:38,311 --> 00:14:41,880
Another worker heats the cane
to make the wood flexible,
222
00:14:41,882 --> 00:14:44,883
then inserts it
in a v-shaped holder
223
00:14:44,885 --> 00:14:47,085
and peers down
the length of the shaft
224
00:14:47,087 --> 00:14:49,988
to assess the direction
of the deformity.
225
00:14:49,990 --> 00:14:52,724
Then he manually
straightens out the cane.
226
00:14:55,228 --> 00:15:00,031
These canes undergo a final step
to add a decorative feature.
227
00:15:00,033 --> 00:15:02,901
A worker sands off some wood
on the crook handle,
228
00:15:02,903 --> 00:15:05,937
creating a flat, oval surface.
229
00:15:05,939 --> 00:15:09,974
He applies glue, then he adheres
a piece of cow horn.
230
00:15:11,945 --> 00:15:13,645
Once the glue dries,
231
00:15:13,647 --> 00:15:16,614
he grinds the horn flush
with the surrounding wood.
232
00:15:21,922 --> 00:15:24,355
the result is a horn inlay.
233
00:15:26,826 --> 00:15:28,660
Wooden canes
also need protection
234
00:15:28,662 --> 00:15:31,262
against moisture and wear.
235
00:15:31,264 --> 00:15:34,766
The factory submerges them
in varnish for a half hour,
236
00:15:34,768 --> 00:15:36,768
so that the varnish
deeply penetrates
237
00:15:36,770 --> 00:15:39,871
the pores of the wood.
238
00:15:39,873 --> 00:15:43,608
Hanging the canes to dry
would leave varnish drip marks,
239
00:15:43,610 --> 00:15:46,444
so the factory uses this
ingenious pulley-driven
240
00:15:46,446 --> 00:15:50,982
contraption that dates back
to the 1900s.
241
00:15:50,984 --> 00:15:53,318
With its wood wheels
and leather belts,
242
00:15:53,320 --> 00:15:56,554
the machine continuously
rotates the canes
243
00:15:56,556 --> 00:16:00,224
to prevent the wet varnish
from dripping as it air dries.
244
00:16:03,096 --> 00:16:06,064
That's how to make
a wooden crook-handled cane.
245
00:16:06,066 --> 00:16:08,900
As you'll see next,
fancier walking canes
246
00:16:08,902 --> 00:16:10,902
require additional steps.
247
00:16:25,418 --> 00:16:28,486
Narrator: Whether it's decorated
with ornately carved wood,
248
00:16:28,488 --> 00:16:33,091
sleek horn or gleaning metal,
brandishing a fancy walking cane
249
00:16:33,093 --> 00:16:35,994
is like wearing
a bold pair of eyeglasses.
250
00:16:35,996 --> 00:16:38,696
What might otherwise
be a bland necessity
251
00:16:38,698 --> 00:16:41,399
can be elevated
to a fashion statement.
252
00:16:45,271 --> 00:16:48,339
Elegant canes can have
horn or knob handles,
253
00:16:48,341 --> 00:16:51,409
or silver-plated
figural handles.
254
00:16:51,411 --> 00:16:55,013
The figural ones are molded
two at a time.
255
00:16:55,015 --> 00:16:58,149
After placing a screw
mechanism in each cavity,
256
00:16:58,151 --> 00:16:59,917
a worker closes the mold
257
00:16:59,919 --> 00:17:02,820
and places it in
a centrifuge machine.
258
00:17:02,822 --> 00:17:07,025
As the mold spins,
he ladles pewter into a funnel
259
00:17:07,027 --> 00:17:10,862
that feeds the channels leading
into the mould cavities.
260
00:17:10,864 --> 00:17:14,298
The centrifugal force shoots
the pewter onto the cavity walls
261
00:17:14,300 --> 00:17:16,134
in an even layer,
262
00:17:16,136 --> 00:17:19,737
where it cools and solidifies
in about five minutes.
263
00:17:19,739 --> 00:17:24,008
Then he stops the machine
and removes the mould.
264
00:17:24,010 --> 00:17:26,377
The worker opens the mold
and extracts
265
00:17:26,379 --> 00:17:28,346
the two pewter castings,
266
00:17:28,348 --> 00:17:33,184
each with it's screw mechanism
securely embedded.
267
00:17:33,186 --> 00:17:35,520
One is a cobra handle.
268
00:17:35,522 --> 00:17:37,922
The other is a dog
and boar handle.
269
00:17:40,293 --> 00:17:42,493
They require
a bit of refinement,
270
00:17:42,495 --> 00:17:45,196
so the next step is
to remove the excess metal
271
00:17:45,198 --> 00:17:47,398
with a rotating wire brush.
272
00:17:49,803 --> 00:17:51,803
A worker then shines
up the surface
273
00:17:51,805 --> 00:17:53,638
with some polishing compound
274
00:17:53,640 --> 00:17:55,640
and a cloth buffing wheel.
275
00:18:01,147 --> 00:18:03,481
he washes off the
polishing compound
276
00:18:03,483 --> 00:18:05,450
and silver-plates the pewter.
277
00:18:08,521 --> 00:18:12,924
The handle will top an equally
elegant ebony shaft.
278
00:18:12,926 --> 00:18:15,927
A worker places the square stick
of ebony in a lathe,
279
00:18:15,929 --> 00:18:17,762
which rounds it.
280
00:18:24,037 --> 00:18:27,805
the shaft goes through several
sanding and polishing steps.
281
00:18:30,877 --> 00:18:33,277
Then a worker drills
a two-inch-deep hole
282
00:18:33,279 --> 00:18:34,812
in the top of it.
283
00:18:39,018 --> 00:18:42,353
He puts some glue in the hole
and screws in the handle.
284
00:18:49,162 --> 00:18:52,230
if silver-plated cobras
aren't your style,
285
00:18:52,232 --> 00:18:55,766
how about a handle
made of white cow horn?
286
00:18:55,768 --> 00:19:00,304
First, a worker heats all but
the tip of the horn in a fire.
287
00:19:00,306 --> 00:19:04,175
This destroy the nerves in the
bone inside the horn's shell.
288
00:19:06,146 --> 00:19:08,746
This horn will be shaped
into a crooked handle
289
00:19:08,748 --> 00:19:11,182
using the same bending machine
the workers use
290
00:19:11,184 --> 00:19:13,751
for wood crook handles.
291
00:19:13,753 --> 00:19:15,620
The base of the horn is hot,
292
00:19:15,622 --> 00:19:20,324
so they use a small block
of wood as a buffer.
293
00:19:20,326 --> 00:19:22,426
After clamping the machine's
guide wheel
294
00:19:22,428 --> 00:19:24,428
against the middle of the horn,
295
00:19:24,430 --> 00:19:28,099
they use their body weight
to move the lever forward,
296
00:19:28,101 --> 00:19:31,502
and wrap the top half of the
horn against the curved form.
297
00:19:38,978 --> 00:19:41,379
before heating the horn,
the worker drilled
298
00:19:41,381 --> 00:19:44,148
a small hole through its tip.
299
00:19:44,150 --> 00:19:48,052
Now he inserts a thin steel wire
through that hole and ties
300
00:19:48,054 --> 00:19:50,621
the wire tightly around
the opposite side
301
00:19:50,623 --> 00:19:53,191
to hold the horn
to the round form.
302
00:19:53,193 --> 00:19:55,259
He sets it aside for a week.
303
00:19:58,431 --> 00:20:02,066
A horn handle undergoes the same
multi-step sanding process
304
00:20:02,068 --> 00:20:04,669
as a wood handle, however,
305
00:20:04,671 --> 00:20:07,071
a worker drills
a hole into the bottom
306
00:20:07,073 --> 00:20:09,540
and screws in an aluminum rod.
307
00:20:09,542 --> 00:20:12,944
This makes the handle easier
to hold while sanding.
308
00:20:17,951 --> 00:20:20,851
the worker removes the final
traces of the outer layer
309
00:20:20,853 --> 00:20:24,722
with a router and finalizes
the crook's shape.
310
00:20:33,900 --> 00:20:36,334
he removes the handle
from the metal rod
311
00:20:36,336 --> 00:20:39,937
and finishes it off
with a fine sanding.
312
00:20:39,939 --> 00:20:42,840
The horn surface is now
as smooth as silk.
313
00:20:50,216 --> 00:20:53,417
he then polishes the handle
on a cotton buffing wheel
314
00:20:53,419 --> 00:20:57,588
using a polishing compound
specially formulated for horn.
315
00:21:00,093 --> 00:21:03,561
That brings out
the color and sheen.
316
00:21:03,563 --> 00:21:05,963
Then the worker screws
and exotic-wood shaft
317
00:21:05,965 --> 00:21:09,834
into the same hole
used for the metal rod.
318
00:21:09,836 --> 00:21:14,405
This fashionable cane, which has
taken 4-6 hours to craft,
319
00:21:14,407 --> 00:21:17,174
is ready to be modeled
on the walkway.
