Narrator: IN THE AMERICAN WILD WEST, THE GUN RULED,

AND THAT GUN WAS USUALLY A SIX-SHOOTER REVOLVER.

TODAY, REPLICAS OF THOSE REVOLVERS

CAN TAKE YOU BACK TO DODGE CITY,

AND THEY DO AT COWBOY SHOOTING COMPETITIONS.

IT'S A CHANCE TO ENGAGE

IN A LITTLE OLD-FASHION GUNSLINGING FOR OLD TIME'S SAKE.

WITH ITS SIX-SHOT CYLINDER

AND INNOVATIVE COCKING MECHANISM,

THE 1873 COLT WAS CARRIED BY THE LIKES OF JESSE JAMES.

THEY START THESE AUTOMATIC REPLICAS

BY SHAPING AND MACHINING THE GUN'S FRAME.

A COMPUTERIZED BLADE CARVES THE CYLINDER.

IT CUTS SLOTS FOR THE AMMUNITION

AND NOTCHES FOR ROTATING THE CYLINDER AFTER A SHOT IS FIRED.

A TECHNICIAN FILES DOWN ROUGH EDGES

SO THE PARTS WILL FIT TOGETHER PERFECTLY.

HE THEN SCREWS THE CURVED GRIP AND THE TRIGGER GUARD

TO THE FRAME.

HE ASSEMBLES THE WOODEN GRIP CASING TO THE METAL BACK STRAP

AND ATTACHES THEM TO THE GRIP.

ONCE HE CONFIRMS IT'S A GOOD FIT,

HE REMOVES THE CASING THE WRITES THE GUN'S SERIAL NUMBER INSIDE.

HE STAMPS A MATCHING NUMBER ONTO THE GRIP

AND POLISHES IT AND THE GUN'S FRAME TO A GLOSSY FINISH.

HE NOW ROLLS THE MODEL NUMBER

AND OTHER IDENTIFYING INFORMATION

ONTO THE GUN'S BARREL.

TO ADD A BIT OF FLOURISH,

AN ARTIST ENGRAVES DESIGNS

COPYING THE ARTWORK ON AN ORIGINAL COLT.

ANOTHER WORKER NOW DIPS THE PARTS IN HOT SALTS,

THEN IN COLD WATER.

A REACTION OCCURS

THAT BOTH HARDENS THE PARTS A BIT AND TINTS THEM.

IN THIS CASE, THEY TURN A BRONZE COLOR.

THIS IS CALLED COLOR CASE HARDENING.

THE GRIP AND TRIGGER GUARD

HAVE BEEN REMOVED FROM THE GUN FRAME FOR COLOR CASING.

THIS MAKES IT EASIER FOR THE TECHNICIAN

TO INSTALL THE CARTRIDGE LOADING GATE ON THE FRAME.

HE FILES DOWN THE MECHANISM FOR ROTATING THE CYLINDER

TO MAKE THE DIMENSIONS PERFECT.

HE THEN INSERTS A BUSHING AND A PIN

IN THE CYLINDER'S CENTER.

HE USES THAT PIN TO INSTALL THE CYLINDER IN THE GUN FRAME.

THE PIN WILL ALSO SERVE AS THE AXIS

FOR THE CYLINDER TO REVOLVE ON.

HE SLIDES A COUPLE OF TEST SLUGS INTO THE CHAMBERS

TO CONFIRM THE GAP BETWEEN THE CYLINDER AND GUN FRAME

IS SPOT ON.

HE THEN FITS THE GUN BARREL TO THE FRAME.

AND, USING A SPECIAL MEASURING ROD,

HE CHECKS THE ALIGNMENT OF THE CYLINDER AND BARREL.

HE TIGHTENS THE BARREL TO THE GUN FRAME,

USING A STICK AS A LEVER.

THE TECHNICIAN AIMS THE ASSEMBLED GUN

AND EYEBALLS THE ALIGNMENT OF THE BARREL TO THE FRAME.

ONCE HE'S CERTAIN

THE CONFIGURATION IS RIGHT ON TARGET,

HE INSTALLS THE GUN'S HAMMER AND TRIGGER.

HE POPS THE CYLINDER BACK INTO THE GUN FRAME

AND INSERTS THE ROD FOR EJECTING SPENT AMMUNITION.

HE SCREWS A SPRING INTO THE SIDE OF THE HAMMER

AND COCKS IT IN ITS THREE DIFFERENT POSITIONS

TO VERIFY THAT IT'S IN WORKING ORDER.

HE THEN REATTACHES THE GRIP AND TRIGGER GUARD.

HE ASSEMBLES A FLAT SPRING TO THE CURVED GRIP.

THIS IS THE MAIN SPRING.

IT TRANSFERS ENERGY FROM THE TRIGGER TO THE HAMMER

TO CAUSE THE REVOLVER TO FIRE.

THEN IT'S OVER TO A GOVERNMENT TESTING FACILITY

CALLED THE PROOF HOUSE.

BEHIND BULLETPROOF GLASS,

SPECIAL EQUIPMENT FIRES AMMUNITION

AT THREE TIMES THE USUAL OPERATING PRESSURE.

IF THE GUN CAN HANDLE THIS, IT'S DEEMED SAFE TO OPERATE.

AFTER A FEW MORE PARTS HAVE BEEN COLOR CASED,

THIS REVOLVER REPLICA IS READY FOR ITS TARGET MARKET.

AND THAT WOULD BE HISTORY BUFFS

WHO ARE INTERESTED IN A REAL BLAST FROM THE PAST.

Narrator: ARC TRAINERS CAN GIVE YOU A FULL-BODY WORKOUT.

THEY PROVIDE A NUMBER OF EXERCISE PROGRAMS

TO CHOOSE FROM,

LIKE STRENGTH TRAINING, WEIGHT LOSS, AND CARDIO.

THEY MONITOR SUCH THINGS

AS HEART RATE AND CALORIES BURNED.

LIKE ANY PIECE OF EXERCISE EQUIPMENT,

USING ONE PROPERLY IS THE KEY TO A SAFE AND HEALTHY WORKOUT.

ARC TRAINERS ARE MADE TO GIVE YOU

A WIDE RANGE OF INCLINE AND RESISTANCE LEVELS

TO LET YOU TRAIN AS EASY OR AS HARD AS YOU LIKE.

TO START, A TUBE LASER

MACHINE-CUTS AND PROFILES THE STEEL TUBING

THAT WILL MAKE THE ARC TRAINER'S SIDE FRAME.

A WORKER CLEANS THE STEEL TUBES, THEN RUNS THEM

THROUGH A COMPUTER-CONTROLLED ROLL-FORMING MACHINE.

THIS MACHINE SHAPES ALL THE STEEL

USED TO BUILD THE ARC TRAINER'S FRAME.

THEY USE A ROBOT TO WELD ALL THE PARTS TOGETHER

BECAUSE ROBOTIC WELDING IS MORE CONSISTENT AND ACCURATE

THAN HAND-WELDING.

THE COMPLETED FRAMES THEN GET A SURFACE PREPARATION,

GIVING THE STEEL A UNIFORM FINISH

THAT IS NOW READY FOR POWDER PAINTING.

WORKERS THEN PAINT THE FRAMES

USING AN ELECTROSTATIC PAINT PROCESS.

THESE GUNS SPRAY ELECTRICALLY CHARGED PAINT PARTICLES

THAT ARE DRAWN TO THE GROUNDED FRAMES

IN A SMOOTH AND EVEN COAT.

THE FRAMES THEN BAKE IN AN OVEN FOR 40 MINUTES

TO CURE THE PAINT.

NEXT COME THE HANDLEBARS.

A WORKER THEN MAKES THEM BY LUBRICATING A RUBBER TUBE

AND SLIDING IT ONTO AN ASSEMBLY FRAME.

HE THEN LOCKS A PREFORMED METAL TUBE IN PLACE

AND LUBRICATES IT, AS WELL.

HE TURNS A HANDWHEEL,

WHICH BRINGS THE TWO TUBES TOGETHER,

FORMING THE HANDGRIP.

HE COMPLETES THE ASSEMBLY BY SCREWING ON AN END CAP.

MEANWHILE, A WORKER ASSEMBLES THE CONTROL PANEL

BY PUTTING ON THE OVERLAYS FOR THE USER INTERFACE.

SHE THEN HOOKS UP THE PRINTED CIRCUIT BOARD

THAT CONTROLS THE UNIT.

SHE CLOSES THE HOUSING

BUT LEAVES THE CONNECTORS EXPOSED

FOR CONNECTION TO THE MAINFRAME LATER.

A WORKER THEN ATTACHES A STEEL SUPPORT FIXTURE ONTO THE FRAME.

NEXT COMES THIS DRIVE-WHEEL ASSEMBLY,

WHICH HE BOLTS ONTO THE SUPPORT FIXTURE.

HE PUTS A DRIVE BELT AROUND A PULLEY

THAT PROVIDES VARIOUS RESISTANCE LEVELS FOR THE USER

AND ROLLS THE BELT ONTO THE DRIVE WHEEL.

HE THEN USES A PNEUMATIC TOOL TO TIGHTEN DOWN THE PULLEY,

WHICH STRETCHES THE DRIVE BELT

AND SETS IT TO THE APPROPRIATE TENSION.

NEXT, HE ATTACHES THE COMPUTER BOARD

THAT CONTROLS THE VARIOUS FITNESS PROGRAMS.

A WORKER THEN INSTALLS THE LEG BARS

ONTO THE ARC TRAINER'S FRAME

AND ATTACHES A FOOT PEDAL ONTO EACH LEG BAR.

HE INSTALLS LINKAGE BARS ONTO THE DRIVE-WHEEL ASSEMBLY.

THEN HE ALIGNS THE DRIVE WHEEL

AND PUTS ON THE MOLDED FRONT HOUSING...

FOLLOWED BY THE PROTECTIVE SIDE COVERS.

HE CONNECTS A LINKAGE BAR

THAT EXTENDS FROM EACH LEG BAR TO THE DRIVE WHEEL,

THEN CONNECTS ONE LINKAGE BAR TO EACH ARM HANDLE.

HE MAKES SURE ALL THE LINKAGE BARS ARE WORKING PROPERLY.

FINALLY, HE TESTS

THE FREE-FLOATING FOOT PEDALS AND THE DUAL-ACTION ARMS,

AS WELL AS ALL THE OTHER FUNCTIONS AND FEATURES.

THESE ARC TRAINERS ARE HIGH-TECH EXERCISE MACHINES.

SOME MODELS EVEN COME WITH A TV.

Narrator: USED-OIL FURNACES GENERATE HEAT

BY BURNING USED OIL WITHOUT HAVING TO REFINE IT.

THESE FURNACES ARE FOUND IN AUTOMOBILE SHOPS,

MAINTENANCE FACILITIES, AND CONSTRUCTION SITES.

TRANSPORT FLEETS AND TRUCKING COMPANIES ALSO USE THEM

TO TURN THE USED OIL THEY PRODUCE

INTO HEAT FOR THEIR FACILITIES.

IT TAKES A SPECIAL FURNACE TO BURN USED OIL.

USED OIL IS THICK AND DIRTY

COMPARED TO RESIDENTIAL FUEL OIL

AND MUST BE TURNED INTO A FINE MIST

TO BURN PROPERLY.

IT ALL STARTS WITH A COMPUTER-CONTROLLED LASER

MAKING WHAT'S CALLED THE FRONT AND REAR FLUE PLATES

OUT OF STEEL.

THE PLATES FOR THIS HOT-AIR FURNACE

ARE MADE OF STAINLESS OR HOT-ROLLED STEEL

DEPENDING ON THE SIZE OF THE UNIT.

A WORKER THEN MAKES WHAT'S KNOWN AS THE HEAT EXCHANGER

BY JOINING THE FLUE PLATES TOGETHER

WITH STEEL TUBES CALLED FLUE TUBES.

THIS DEVICE IS CALLED A SWAGGER MACHINE.

IT EXPANDS JUST THE ENDS OF THE FLUE TUBES,

BINDING THEM IN PLACE WITH THE FLUE PLATE.

NEXT, HE ASSEMBLES THE SECTION IN WHICH HOT GASES COLLECT

AFTER PASSING THROUGH THE FLUE TUBES

ON THEIR WAY OUT OF THE FURNACE.

HE THEN SETS A COMBUSTION CHAMBER

ON THE TOP OF THE HEAT EXCHANGER

AND WELDS THEM TOGETHER.

HE COMPLETES THE HEAT-EXCHANGER ASSEMBLY

BY WELDING ON A BASE EQUIPPED WITH TWO AIR-DEFLECTOR PLATES.

THESE SQUARE PLATES HELP DIRECT THE AMBIENT AIR

AS IT ENTERS THE FURNACE

AND CIRCULATES AROUND THE COMBUSTION CHAMBER.

MEANWHILE, AN ELECTROSTATIC POWDER-COATING MACHINE

PAINTS THE OUTSIDE COVERS FOR THE FURNACE.

NEXT, THEY PUT ON INNER AIR DEFLECTORS,

THEN ASSEMBLE THE CABINET.

THEY BOLT EVERYTHING IN PLACE, THEN PUT ON AN INSULATED DOOR.

NOW HE HOOKS UP A BLOWER CONTROL BOX.

THIS ELECTRICAL BOX REGULATES

WHEN HOT AIR IS SENT INTO A ROOM.

A WORKER THEN CONNECTS A TESTER BOX

TO THE TEMPERATURE CONTROLS

THAT MEASURE THE TEMPERATURE INSIDE THE FURNACE.

HE RUNS A NUMBER OF TESTS

TO CONFIRM THAT BOTH THE BLOWER AND THE BURNER

WILL TURN ON OR OFF WHEN THEY'RE SUPPOSED TO.

HE VERIFIES THE OPERATION OF THE DOOR

THAT ALLOWS FOR CLEANING OUT ASH RESIDUE.

A TECHNICIAN INSTALLS A 100-WATT PENCIL HEATER

INSIDE A BRASS NOZZLE ADAPTOR,

THEN THREADS A THERMOSTAT INTO IT.

THIS NOZZLE ADAPTOR HEATS THE OIL

AND TURNS IT INTO A FINE MIST SO IT BURNS PROPERLY.

SHE THEN ATTACHES ASSEMBLY FITTINGS TO THE ADAPTOR

SO SHE CAN LATER MOUNT IT INSIDE A BURNER HOUSING.

SHE CHECKS THESE FITTINGS WITH A LEVELING TOOL

TO ENSURE THE ADAPTOR WILL GO ON STRAIGHT INSIDE THE HOUSING.

SHE ALSO INSTALLS AN ASSEMBLY THAT CONTROLS

OIL FLOW, TEMPERATURE, AND AIR PRESSURE.

THEN SHE MOUNTS THE NOZZLE ADAPTOR

AND COVERS IT WITH A RETENTION HEAD

THAT SHAPES THE FLAME FOR OPTIMAL HEAT,

COMPLETING THE BURNER ASSEMBLY.

A WORKER THEN HOOKS UP

THE USED-OIL AND COMPRESSED-AIR LINES

TO BEGIN TESTING THE BURNER.

HE TURNS ON THE OIL, IGNITES THE BURNER,

AND LOOKS THROUGH AN OBSERVATION PORT

TO VERIFY THE BURNER IS WORKING PROPERLY.

A CLOSER LOOK SHOWS THE FLAME IS AT THE RIGHT INTENSITY

FOR OPTIMAL HEAT WITH MINIMAL EMISSIONS.

THE FURNACE IS NOW READY TO TURN USED OIL INTO USEFUL HEAT.

Narrator: TOP-OF-THE-LINE PIZZA CUTTERS AND VEGETABLE PEELERS

CAN BE A PLEASURE TO USE.

THEY MAKE PREPARING AND SERVING YOUR FAVORITE FOODS

QUICKER AND EASIER

AND ARE ERGONOMICALLY DESIGNED FOR STYLE AND COMFORT.

THEY ARE ALSO EASY TO CLEAN AND GUARANTEED FOR LIFE.

VEGETABLE PEELERS AND PIZZA CUTTERS WORK LIKE A CHARM,

MAKING STRAIGHT CUTS

WITHOUT DAMAGING YOUR PANS OR YOUR FINGERS.

QUALITY PIZZA CUTTERS START

WITH CUTLERY-GRADE, HIGH-CARBON STAINLESS STEEL

FROM WHICH A STAMPING PRESS PUNCHES THE CUTTER BLADES.

THE BLADES GO

THROUGH A THREE-STEP HEAT-TREATING PROCESS.

FIRST, THEY ENTER A HIGH-TEMPERATURE FURNACE.

THEN IT'S INTO A DEEP FREEZER

TO MAXIMIZE HARDNESS AND CORROSION RESISTANCE.

FINALLY, THEY GO INTO A TEMPERING OVEN,

WHICH INCREASES THE DURABILITY OF THE METAL.

A POLISHING MACHINE WITH TWO BUFFING HEADS

THEN POLISHES BOTH SIDES OF THE BLADE,

GIVING IT A PROTECTIVE AND COSMETIC FINISH.

A WORKER THAN LOADS THE BLADE ONTO A BEVEL-GRINDING MACHINE

THAT THINS OUT THE EDGE OF THE BLADE.

IT GRINDS A BEVELED EDGE THAT IS THIN ENOUGH TO CUT PIZZA

BUT NOT SHARP ENOUGH

TO CUT YOUR FINGER OR DAMAGE A CUTTING SURFACE.

A WORKER PUTS A STEEL-BAR INSERT

INTO AN INJECTION MOLDING MACHINE

THAT MAKES THE SOFT-POLYMER HANDLE.

HE THEN COOLS IT DOWN IN WATER.

HE PUTS THE HANDLES ON AN EXTRACTION FIXTURE

WHICH REMOVES THE INSERTS,

MAKING THE HANDLES READY FOR ASSEMBLY

ALONG WITH ALL THE OTHER MOLDED PARTS.

HE THEN ATTACHES WHAT'S CALLED A SWING ARM TO THE BLADE HOLDER,

AND HE SECURES IT IN PLACE WITH A SCREW.

HE DIPS THE TIP OF THE BLADE HOLDER INTO LUBRICANT

AND USES A PNEUMATIC-ASSEMBLY FIXTURE

TO INSERT THE BLADE HOLDER INTO THE HANDLE PERMANENTLY.

USING THE SWING ARM,

HE SNAP-FITS THE BLADE ONTO THE BLADE HOLDER

AND HIDES THE SWING-ARM SCREW WITH A COVER CAP.

FINALLY, HE ENSURES THE BLADE ROLLS PROPERLY AND SAFELY

SO IT WILL CUT THROUGH PIZZA WITH EASE.

THE FINEST VEGETABLE PEELERS

ALSO DO THEIR JOB QUICKLY AND EFFECTIVELY.

THEY ALSO START

WITH CUTLERY-GRADE STAINLESS-STEEL BLADES

THAT UNDERGO TEMPERING

TO ENSURE THE METAL IS DURABLE AND CORROSION-RESISTANT.

AFTER CLEANING AND POLISHING,

THE BLADES ARE DRIED

IN A VIBRATING MEDIUM OF GROUND CORNCOB,

THEN REMOVED FROM THE TUB BY A MAGNET.

THE BLADES ARE NOW READY FOR SHARPENING.

A WORKER MOUNTS THE PEELER BLADES

ON A COMPUTER-CONTROLLED EDGE-GRINDING MACHINE.

THE GRINDER SHARPENS ONE EDGE OF EACH BLADE AT A TIME.

ONCE BOTH SIDES OF THE PEELER BLADES ARE FULLY SHARPENED,

THEY'RE READY FOR ASSEMBLY.

MEANWHILE, AN INJECTION MOLDING MACHINE

MAKES THE BLADE HOLDERS.

A WORKER DIPS EACH BLADE HOLDER INTO LUBRICANT

AND INSERTS IT INTO THE MOLDED SOFT-POLYMER HANDLE,

JOINING THEM TOGETHER PERMANENTLY.

FINALLY, HE ATTACHES THE BLADE

BY DEFLECTING THE HOLDER JUST ENOUGH

TO INSERT THE TIP OF THE BLADE INTO A TINY HOLE.

THESE TOP-QUALITY VEGETABLE PEELERS

ARE SOLD INDIVIDUALLY OR IN COMBINATION

WITH OTHER KITCHEN UTENSILS LIKE PIZZA CUTTERS,

AND THEY SURE ARE HANDY IN THE KITCHEN,

EVEN IF YOU'RE NOT.
