00:00:05,068 --> 00:00:08,034
Captions paid for by
Discovery communications
3
00:00:51,137 --> 00:00:54,310
Narrator: the jaws of life
Were first used in 1963
4
00:00:54,310 --> 00:00:57,000
To free racecar drivers
From car crashes.
5
00:00:57,000 --> 00:00:58,310
It was so big,
6
00:00:58,310 --> 00:01:01,586
It had to be suspended
From the back of a pickup truck.
7
00:01:01,586 --> 00:01:04,241
Today it weighs
As little as 33 pounds
8
00:01:04,241 --> 00:01:07,344
And is small enough
For one person to operate.
9
00:01:07,344 --> 00:01:10,896
It can free an accident victim
From a car in minutes.
10
00:01:15,241 --> 00:01:19,000
In an emergency situation,
Timing is everything.
11
00:01:22,413 --> 00:01:26,896
A rescue tool has to pry open
A vehicle as easily as a tin can
12
00:01:26,896 --> 00:01:29,103
Or cut through solid steel
Like butter,
13
00:01:29,103 --> 00:01:32,172
Because a few seconds
Can make all the difference.
14
00:01:39,068 --> 00:01:40,586
What gives the cutting blades
15
00:01:40,586 --> 00:01:43,931
And the spreading arms
Their power is hydraulic fluid.
16
00:01:48,655 --> 00:01:51,103
The jaws of life begin
With a milling machine
17
00:01:51,103 --> 00:01:52,689
That shapes the spreader arms
18
00:01:52,689 --> 00:01:56,034
From a bar of solid
Aircraft-grade aluminum.
19
00:02:02,758 --> 00:02:07,137
The spreader arms then get
A protective coating.
20
00:02:07,137 --> 00:02:12,103
A lathe now makes the cap that
Fits on the end of the tool.
21
00:02:12,103 --> 00:02:15,344
A high-speed carbide tip shapes
The solid aluminum
22
00:02:15,344 --> 00:02:18,413
Into a finished endcap
That is then drilled
23
00:02:18,413 --> 00:02:22,000
And treated to a coat
Of rust-resistant protection.
24
00:02:27,620 --> 00:02:33,413
Arms that both cut and spread
Are made from tool steel.
25
00:02:33,413 --> 00:02:37,551
A surface grinder ensures that
The two arms are perfectly flat.
26
00:02:39,896 --> 00:02:41,620
A worker installs a seal
27
00:02:41,620 --> 00:02:43,413
That prevents
The hydraulic fluid
28
00:02:43,413 --> 00:02:45,586
From leaking out
Of the cylinder.
29
00:02:48,137 --> 00:02:50,965
He lubricates a piston
With hydraulic fluid
30
00:02:50,965 --> 00:02:55,310
So it slides into the cylinder
Without damaging the interior.
31
00:02:58,551 --> 00:02:59,896
Then he taps it in
32
00:02:59,896 --> 00:03:02,827
So it will connect
With the link assembly.
33
00:03:06,689 --> 00:03:09,137
He attaches a link assembly
To the piston
34
00:03:09,137 --> 00:03:12,620
And secures it in place.
35
00:03:12,620 --> 00:03:15,241
The link assembly relays power
36
00:03:15,241 --> 00:03:17,758
To the cutting blades
Or spreader arms.
37
00:03:21,448 --> 00:03:24,655
He then attaches an assembled
End cap to the cylinder
38
00:03:24,655 --> 00:03:26,793
And bolts it in place.
39
00:03:32,379 --> 00:03:33,724
He connects the two hoses
40
00:03:33,724 --> 00:03:38,103
That lead to the tool's
Hydraulic cylinder.
41
00:03:38,103 --> 00:03:41,206
He puts on a handgrip
That protects the hoses
42
00:03:41,206 --> 00:03:44,689
And makes it easier
To work the thumbwheel.
43
00:03:44,689 --> 00:03:48,413
He tightens the bolts
And completes the control valve.
44
00:03:48,413 --> 00:03:50,896
He then attaches
The front handle
45
00:03:50,896 --> 00:03:54,241
That allows the operator
To hold the tool safely.
46
00:03:57,000 --> 00:03:59,551
This protective guard will keep
All the moving components
47
00:03:59,551 --> 00:04:01,517
Away from a rescuer's hands.
48
00:04:07,655 --> 00:04:11,793
Then he aligns the holes
In the blades to the tool
49
00:04:11,793 --> 00:04:15,068
And inserts a steel pivot pin.
50
00:04:22,724 --> 00:04:24,482
He puts on a locknut,
51
00:04:24,482 --> 00:04:27,344
And, as with all fasteners
On the rescue tool,
52
00:04:27,344 --> 00:04:30,758
He tightens it to a precise
Engineering specification.
53
00:04:35,758 --> 00:04:37,586
After mounting the blades,
54
00:04:37,586 --> 00:04:39,241
He secures them
To the link assembly
55
00:04:39,241 --> 00:04:42,586
With a steel-alloy pin
And a snap ring.
56
00:04:49,379 --> 00:04:52,517
Then he folds
The protective guard back
57
00:04:52,517 --> 00:04:54,137
And finishes assembling
The tool.
58
00:05:09,000 --> 00:05:11,724
A worker then tests the tool,
Which has been filled
59
00:05:11,724 --> 00:05:14,413
With fire-resistant
Hydraulic fluid.
60
00:05:14,413 --> 00:05:18,241
The fixture he uses is designed
To measure the pressure
61
00:05:18,241 --> 00:05:21,137
At the strongest point
In the cutting.
62
00:05:26,379 --> 00:05:29,620
The tool passes
The pressure test.
63
00:05:31,517 --> 00:05:32,931
Whether it's a rescue tool
64
00:05:32,931 --> 00:05:35,172
That cuts through metal
Or pries it open,
65
00:05:35,172 --> 00:05:38,931
Emergency-response teams
Arriving on an accident scene
66
00:05:38,931 --> 00:05:41,620
Will have what it takes
To help save lives.
67
00:05:53,034 --> 00:05:54,896
Narrator: the quest
For the perfect tree
68
00:05:54,896 --> 00:05:56,344
Is a rite of the holiday season.
69
00:05:56,344 --> 00:05:58,137
And ever since
The late 19th century,
70
00:05:58,137 --> 00:06:00,931
People have been trying to come
Up with an artificial version.
71
00:06:00,931 --> 00:06:02,896
First,
There were feather trees
72
00:06:02,896 --> 00:06:05,379
And, later,
Trees made of animal bristles.
73
00:06:05,379 --> 00:06:07,413
But by the 1960s,
74
00:06:07,413 --> 00:06:12,000
The use of synthetics finally
Gave us the perfect fake fir.
75
00:06:13,965 --> 00:06:17,689
Today's faux firs
Can be several stories tall --
76
00:06:17,689 --> 00:06:20,068
Big enough for your town square.
77
00:06:20,068 --> 00:06:22,655
You can get them
With many of the trimmings
78
00:06:22,655 --> 00:06:25,586
So decorating
Isn't such a stretch.
79
00:06:25,586 --> 00:06:29,827
These big artificial trees start
With a steel skeleton.
80
00:06:29,827 --> 00:06:32,724
Rollers bend steel tubing
Into arcs.
81
00:06:32,724 --> 00:06:36,931
They'll be joined to form
The base of the framework.
82
00:06:36,931 --> 00:06:40,517
Workers weld vertical supports
To the arcs,
83
00:06:40,517 --> 00:06:42,965
Building the structure
In sections.
84
00:06:47,000 --> 00:06:48,655
A spray of polyester powder
85
00:06:48,655 --> 00:06:51,068
Gives the welded metal
A smooth finish
86
00:06:51,068 --> 00:06:54,206
That's actually tougher
Than paint.
87
00:06:54,206 --> 00:06:57,620
They bake the parts
To set the coating.
88
00:07:01,034 --> 00:07:02,655
After a quick cooling,
89
00:07:02,655 --> 00:07:05,655
It's time to assemble
All the pieces.
90
00:07:09,241 --> 00:07:10,862
They fasten
The structure together
91
00:07:10,862 --> 00:07:13,275
With u-bolts and a ratchet.
92
00:07:17,620 --> 00:07:20,620
Meanwhile,
A roll of green pvc plastic
93
00:07:20,620 --> 00:07:22,137
Winds its way towards a roller
94
00:07:22,137 --> 00:07:25,793
Equipped
With many circular cutters.
95
00:07:25,793 --> 00:07:28,827
They slice it
Into 4-inch-wide strips.
96
00:07:31,206 --> 00:07:33,137
Each of the narrow
Plastic strips
97
00:07:33,137 --> 00:07:35,965
Then goes under a roller
With even more blades.
98
00:07:35,965 --> 00:07:38,758
They shred it into
A needlelike configuration,
99
00:07:38,758 --> 00:07:41,000
Leaving a solid spine
At the center
100
00:07:41,000 --> 00:07:44,586
To hold the simulated needles
Together.
101
00:07:48,827 --> 00:07:53,310
An automated spool then winds up
The fringed green pvc.
102
00:07:55,655 --> 00:07:59,310
These artificial needles come in
An assortment of colors,
103
00:07:59,310 --> 00:08:03,344
So if you want glitz,
You can really go out on a limb.
104
00:08:05,862 --> 00:08:08,448
Here,
Streams of the fringed green
105
00:08:08,448 --> 00:08:13,206
And a strip of brown pvc travel
Over tension-control guides.
106
00:08:13,206 --> 00:08:18,482
Steel wire unwinds and merges
With the green and brown pvc.
107
00:08:18,482 --> 00:08:21,241
This machine
Twists them together.
108
00:08:21,241 --> 00:08:25,344
The brown strip lands at
The core of the twisted fringe,
109
00:08:25,344 --> 00:08:29,103
Creating the illusion
Of a stem among the needles.
110
00:08:29,103 --> 00:08:30,965
This twisting technology
111
00:08:30,965 --> 00:08:34,586
Churns out a continuous supply
Of artificial greenery.
112
00:08:36,379 --> 00:08:39,896
Giant scissors slice it
To the correct length.
113
00:08:45,517 --> 00:08:48,137
To make branches
That appear snow-tipped,
114
00:08:48,137 --> 00:08:51,068
This machine twists
And then frosts the pvc needles
115
00:08:51,068 --> 00:08:53,758
With a spray
Of white latex paint.
116
00:08:59,724 --> 00:09:01,310
They use this ring fastener
117
00:09:01,310 --> 00:09:05,689
To crimp the artificial foliage
Together, branch by branch.
118
00:09:05,689 --> 00:09:09,103
This creates a tightly knit
Mass of greenery
119
00:09:09,103 --> 00:09:12,724
That will be used to cover
The tree's framework.
120
00:09:20,724 --> 00:09:22,551
They apply single garlands
121
00:09:22,551 --> 00:09:25,172
On key parts
Of the tree grid first,
122
00:09:25,172 --> 00:09:28,448
Using a handheld
Pneumatic fastener.
123
00:09:28,448 --> 00:09:31,827
They fill in
The sections between them
124
00:09:31,827 --> 00:09:33,793
With the assembled branches.
125
00:09:33,793 --> 00:09:37,310
This is easier than
Attaching them to the framework
126
00:09:37,310 --> 00:09:39,000
Branch by branch.
127
00:09:42,103 --> 00:09:43,482
They string the lights
128
00:09:43,482 --> 00:09:46,310
And then plug them in
To check each bulb.
129
00:09:49,827 --> 00:09:53,241
After all,
It's easier to change one now
130
00:09:53,241 --> 00:09:55,275
Than after the tree
Has been erected,
131
00:09:55,275 --> 00:09:58,206
Especially since this one
Will be a story and a half tall.
132
00:09:58,206 --> 00:10:02,586
They also wire the ornaments
To the branches.
133
00:10:02,586 --> 00:10:04,931
It's one less job
For the customer to do.
134
00:10:06,862 --> 00:10:09,413
And now it's time
To put up the tree.
135
00:10:11,034 --> 00:10:13,172
They bolt the cone
Of wired greenery
136
00:10:13,172 --> 00:10:14,586
To the lower framework...
137
00:10:16,827 --> 00:10:19,620
...And then hook the panels
Of artificial greenery
138
00:10:19,620 --> 00:10:21,655
Onto the rest of the structure.
139
00:10:24,896 --> 00:10:26,482
It has taken just one day
140
00:10:26,482 --> 00:10:29,172
For this artificial tree
To come together,
141
00:10:29,172 --> 00:10:31,448
Where growing a real one
This size
142
00:10:31,448 --> 00:10:33,482
Would take many years.
143
00:10:33,482 --> 00:10:36,724
And the convenience is unreal.
144
00:10:53,620 --> 00:10:55,379
Narrator: soda crackers
Are also called saltines,
145
00:10:55,379 --> 00:10:59,620
Originally a brand name that
Over time became a generic term.
146
00:10:59,620 --> 00:11:01,172
You can eat them plain
147
00:11:01,172 --> 00:11:04,793
Or spread something on them
Or crumble them into soup.
148
00:11:04,793 --> 00:11:07,068
Doctors even recommend
Eating soda crackers
149
00:11:07,068 --> 00:11:08,206
When you're nauseous,
150
00:11:08,206 --> 00:11:11,586
Because they're dry
And easy to digest.
151
00:11:15,103 --> 00:11:17,862
They're flat and bumpy
On the outside,
152
00:11:17,862 --> 00:11:19,344
With a tasty texture
153
00:11:19,344 --> 00:11:22,896
Resulting from some interesting
Chemical reactions.
154
00:11:22,896 --> 00:11:25,517
Workers first dump ice
Into a trough
155
00:11:25,517 --> 00:11:29,137
To prevent the dough from
Overheating during fermentation.
156
00:11:29,137 --> 00:11:30,344
The first ingredient
157
00:11:30,344 --> 00:11:32,931
Is a specific amount
Of finished dough
158
00:11:32,931 --> 00:11:36,103
To kick-start the fermentation
Of this new batch.
159
00:11:36,103 --> 00:11:39,827
To that, they add water,
Wheat flour, yeast,
160
00:11:39,827 --> 00:11:43,034
And enzymes
To help the fermentation.
161
00:11:43,034 --> 00:11:46,827
A mixer blends the ingredients
For about 5 minutes.
162
00:11:46,827 --> 00:11:49,620
They let the dough sit
For 16 hours
163
00:11:49,620 --> 00:11:52,137
While the enzymes break down
The starch and the wheat
164
00:11:52,137 --> 00:11:53,689
Into simple sugars.
165
00:11:53,689 --> 00:11:56,482
The yeast then reacts
With those sugars,
166
00:11:56,482 --> 00:12:00,724
Producing carbon-dioxide gas,
Which makes the dough rise.
167
00:12:03,000 --> 00:12:06,068
Then they adjust
The fermented dough's ph level
168
00:12:06,068 --> 00:12:07,620
With sodium bicarbonate
169
00:12:07,620 --> 00:12:10,965
To produce the right flavor,
Color, and shelf life.
170
00:12:10,965 --> 00:12:15,137
Then, for additional flavoring,
Some salt...
171
00:12:15,137 --> 00:12:18,724
Malted barley flour...
172
00:12:18,724 --> 00:12:20,655
And vegetable oil.
173
00:12:26,310 --> 00:12:30,000
Then the mixer remixes
The dough for about 5 minutes
174
00:12:30,000 --> 00:12:32,551
To blend in
These new ingredients.
175
00:12:34,275 --> 00:12:37,379
Now they let the dough ferment
For another 6 hours.
176
00:12:37,379 --> 00:12:38,793
The sodium bicarbonate
177
00:12:38,793 --> 00:12:41,137
Counteracts the acidity
This produces
178
00:12:41,137 --> 00:12:43,655
And relaxes the gluten
So that the dough
179
00:12:43,655 --> 00:12:45,931
Now breaks easily
When stretched --
180
00:12:45,931 --> 00:12:48,655
The perfect consistency
For soda crackers.
181
00:12:48,655 --> 00:12:51,689
A machine then extrudes
The massive dough
182
00:12:51,689 --> 00:12:54,689
Into a sheet
That's 2 inches thick
183
00:12:54,689 --> 00:12:57,793
And folds the sheet
Over itself 3 times.
184
00:13:01,793 --> 00:13:04,551
This folding creates
The light and flaky layers
185
00:13:04,551 --> 00:13:07,448
Inside the cracker.
186
00:13:07,448 --> 00:13:11,000
The dough sheet then goes
Through a series of rollers
187
00:13:11,000 --> 00:13:13,517
That reduce it
To its final thickness,
188
00:13:13,517 --> 00:13:15,448
About a millimeter.
189
00:13:18,034 --> 00:13:20,241
A revolving die
Cuts the cracker shapes,
190
00:13:20,241 --> 00:13:22,586
Perforations and all.
191
00:13:22,586 --> 00:13:24,586
The little pins puncture
The dough
192
00:13:24,586 --> 00:13:27,000
And push it firmly
Onto the conveyor belt.
193
00:13:27,000 --> 00:13:29,379
This keeps the dough
From deforming
194
00:13:29,379 --> 00:13:33,413
When moisture and gases escape
During the baking process.
195
00:13:33,413 --> 00:13:37,413
From there, the sheet passes
Under a shower of salt.
196
00:13:41,448 --> 00:13:43,827
The sheet
Now takes a three-minute trip
197
00:13:43,827 --> 00:13:48,344
Through a long oven with
Different temperature zones.
198
00:13:48,344 --> 00:13:53,448
Gas flames bake the dough
From above and below.
199
00:13:53,448 --> 00:13:57,034
The heat transforms the
Sodium bicarbonate in the dough
200
00:13:57,034 --> 00:13:58,689
Into carbon-dioxide gas,
201
00:13:58,689 --> 00:14:01,379
Which then breaks through
And escapes.
202
00:14:01,379 --> 00:14:03,448
This drives out trapped moisture
203
00:14:03,448 --> 00:14:06,068
And forms blisters
In the crackers.
204
00:14:07,862 --> 00:14:10,620
As the sheet of baked crackers
Exits the oven,
205
00:14:10,620 --> 00:14:13,103
A roller breaks it into rows.
206
00:14:20,758 --> 00:14:24,068
The rows then run from
One conveyor belt to the next,
207
00:14:24,068 --> 00:14:26,344
Stacking like roof shingles.
208
00:14:29,275 --> 00:14:31,172
Alignment wheels
Keep them straight
209
00:14:31,172 --> 00:14:33,758
Until the next set of wheels
Gently breaks the rows
210
00:14:33,758 --> 00:14:36,310
Into individual crackers.
211
00:14:45,172 --> 00:14:48,068
Each row makes its way
Through a series of gates
212
00:14:48,068 --> 00:14:50,103
That guide it onto a track
213
00:14:50,103 --> 00:14:52,172
That leads
To the packaging equipment.
214
00:14:59,206 --> 00:15:00,862
The crackers are upright now,
215
00:15:00,862 --> 00:15:03,103
And the machine
Begins dividing them
216
00:15:03,103 --> 00:15:05,931
According to the number
Of crackers per package --
217
00:15:05,931 --> 00:15:08,620
In this case,
Those little 2-cracker packs
218
00:15:08,620 --> 00:15:11,689
You often get with soup.
219
00:15:18,103 --> 00:15:20,758
The cracker pairs enter
The wrapping machine,
220
00:15:20,758 --> 00:15:24,758
Which sandwiches them between
A sheet of printed plastic film.
221
00:15:24,758 --> 00:15:27,034
A wheel then
Simultaneously seals
222
00:15:27,034 --> 00:15:29,586
And cuts the wrapper
Between each pair.
223
00:15:30,655 --> 00:15:33,310
This all happens
At an astonishing rate
224
00:15:33,310 --> 00:15:35,758
Of 525 packages per minute.
225
00:15:35,758 --> 00:15:39,448
And that's the way
The cracker crumbles.
226
00:15:54,000 --> 00:15:55,724
Narrator: ratchets come
In many shapes and sizes
227
00:15:55,724 --> 00:15:58,172
And can tackle almost any job.
228
00:15:58,172 --> 00:16:01,896
Ratchets with socket attachments
Deliver more power and speed
229
00:16:01,896 --> 00:16:04,724
Without slipping
Or damaging the bolt or nut.
230
00:16:04,724 --> 00:16:07,965
Just snap an interchangeable
Socket onto the ratchet,
231
00:16:07,965 --> 00:16:11,689
And you're ready to get the job
Done quickly and properly.
232
00:16:14,448 --> 00:16:16,275
Versatile and easy to use,
233
00:16:16,275 --> 00:16:19,448
A ratchet tightens or loosens
Nuts and bolts
234
00:16:19,448 --> 00:16:21,103
In a continuous motion.
235
00:16:21,103 --> 00:16:23,551
It uses removable sockets
236
00:16:23,551 --> 00:16:27,068
That fit many different sizes
Of fittings and fasteners.
237
00:16:27,068 --> 00:16:30,655
To start, a steel bar travels
Into a shearing machine
238
00:16:30,655 --> 00:16:32,655
That cuts it
Into specific lengths.
239
00:16:37,793 --> 00:16:40,379
These pieces, called billets,
240
00:16:40,379 --> 00:16:42,931
Will be used
To make the ratchet.
241
00:16:45,310 --> 00:16:48,413
A machine feeds the billets
Into an induction coil,
242
00:16:48,413 --> 00:16:52,551
Which heats them to about
1,800 degrees fahrenheit.
243
00:16:55,206 --> 00:16:59,275
A forge press then shapes
The soft billets into ratchets.
244
00:17:03,827 --> 00:17:07,827
The first die creates
The ratchet's general form.
245
00:17:07,827 --> 00:17:11,482
The second die gives it
Its finished shape.
246
00:17:11,482 --> 00:17:15,620
And the third die cuts off
Excess metal.
247
00:17:15,620 --> 00:17:19,103
The ratchets exit
The forge press
248
00:17:19,103 --> 00:17:21,896
And fall into a collection box,
Where they cool.
249
00:17:24,551 --> 00:17:27,551
Then a vertical milling machine
Prepares the body cavity
250
00:17:27,551 --> 00:17:30,275
To receive the internal
Working parts of the ratchet,
251
00:17:30,275 --> 00:17:32,137
Called the gear assembly.
252
00:17:36,379 --> 00:17:40,068
A worker then places the ratchet
On a hydraulic press,
253
00:17:40,068 --> 00:17:41,965
Which stamps the brand name
254
00:17:41,965 --> 00:17:45,206
And the on-and-off indicator
On the ratchet's face.
255
00:17:47,379 --> 00:17:51,206
A lathe cuts away the rough
Forged metal from the handle
256
00:17:51,206 --> 00:17:53,068
And trims off the end,
257
00:17:53,068 --> 00:17:55,586
Making it ready
To receive the handgrip.
258
00:17:58,448 --> 00:18:00,793
A worker then grinds
Any rough edges
259
00:18:00,793 --> 00:18:03,344
Off the machined ratchet.
260
00:18:07,413 --> 00:18:10,172
Then he crimps each side
Of the smooth handle
261
00:18:10,172 --> 00:18:13,206
So it will hold
A rubber handgrip in place.
262
00:18:16,827 --> 00:18:20,275
The ratchets now undergo
A 3-stage tempering process
263
00:18:20,275 --> 00:18:23,620
That hardens
And strengthens the metal.
264
00:18:28,482 --> 00:18:31,241
Ceramic stones
And a chemical solution
265
00:18:31,241 --> 00:18:35,827
Prepare the ratchets
For nickel and chrome plating.
266
00:18:35,827 --> 00:18:38,310
A plating machine
Cleans the ratchets,
267
00:18:38,310 --> 00:18:43,448
Then treats them to a nickel
And a trivalent chrome plating.
268
00:18:43,448 --> 00:18:47,965
The two platings make
The ratchets corrosion-resistant
269
00:18:47,965 --> 00:18:50,655
And give them
A bright cosmetic finish.
270
00:18:53,344 --> 00:18:56,965
A worker then lubricates
The ratchet cavity,
271
00:18:56,965 --> 00:18:58,965
Puts in an on-and-off switch
272
00:18:58,965 --> 00:19:02,275
And a spacer to support
Additional components.
273
00:19:08,724 --> 00:19:11,931
A worker sets a retention ball
Onto a ratchet gear,
274
00:19:11,931 --> 00:19:15,137
Then a punch press
Locks it in place.
275
00:19:18,689 --> 00:19:21,448
Next they fit a gear mechanism
Into the cavity,
276
00:19:21,448 --> 00:19:23,827
Then attach
All the internal components
277
00:19:23,827 --> 00:19:26,862
That control the movements
Of the ratchet.
278
00:19:30,379 --> 00:19:31,724
Once completed,
279
00:19:31,724 --> 00:19:35,379
The gear assembly allows
Or restricts movement.
280
00:19:40,758 --> 00:19:44,724
So, putting the assembly into
Either the on or off position
281
00:19:44,724 --> 00:19:48,724
Is all it takes to tighten
Or loosen a nut or bolt.
282
00:19:50,206 --> 00:19:53,310
She then puts a rubber seal
Onto a cover plate
283
00:19:53,310 --> 00:19:55,448
And closes up the ratchet.
284
00:20:01,793 --> 00:20:05,310
She makes sure the gear assembly
Works properly.
285
00:20:05,310 --> 00:20:08,620
Finally, this machine
Friction-fits a handle
286
00:20:08,620 --> 00:20:10,689
On the ratchet's shaft.
287
00:20:14,034 --> 00:20:16,310
Evolving from a steel bar
288
00:20:16,310 --> 00:20:19,034
To a finished product
In 10 steps,
289
00:20:19,034 --> 00:20:22,241
The ratchets must undergo
A final test of strength
290
00:20:22,241 --> 00:20:26,172
To prove they meet
The highest quality standards.
291
00:20:30,172 --> 00:20:34,275
Ratchet sets are available
In a variety of sizes.
292
00:20:34,275 --> 00:20:38,275
They're used for big
And small jobs by handymen
293
00:20:38,275 --> 00:20:41,275
And professional mechanics
Alike.
