    Narrator: A VERTICAL MILLING TOOL SCULPTS
    A RECESS IN THE BLANK TO SEAT AN O-RING SEALER.
    THEN, SWITCHING BITS,
    THE MACHINE CONTOURS THE OUTSIDE OF THE BLANK,
    TAKING IT FROM RECTANGULAR TO ROUND.
    OTHER TOOLS CARVE A LARGE HOLE IN THE CENTER
    AND PROFILE THE INNER DIAMETER
    SO THAT THE PART WILL MATE TO THE TANK.
    THIS RING IS DESIGNED TO BE REMOVABLE
    TO ACCESS THE TANK FOR MAINTENANCE.
    HERE'S THE BLANK BEFORE AND AFTER MACHINING.
    LIKE POWERFUL COOKIE CUTTERS,
    COMPUTERIZED PUNCHES CUT OUT NUMEROUS PARTS
    FROM AN ALUMINUM SHEET.
    THEY INCLUDE THE OIL-TANK BODY,
    THE TOP, AND OTHER ASSEMBLY PIECES.
    TO MAKE THE TANK BODY CYLINDRICAL,
    A WORKER TURNS A CRANK TO CURL IT AROUND A ROLLER.
    THIS TANK BODY IS CALLED THE WRAPPER.
    A WORKER WELDS THE TANK RING TO THE BOTTOM CONE,
    CREATING A THICK SEAM ALL THE WAY AROUND.
    HE THEN SEALS THE SEAM OF THE CYLINDRICAL WRAPPER BODY
    AND WELDS A TOP CAP TO A DEAERATING BAFFLE.
    AIR WILL RISE THROUGH IT AND VENT IT INTO
    AND OUT OF A SIDE CHAMBER, LEAVING ONLY OIL IN THE TANK.
    HE FITS AN ADAPTER RING TO THE UPPER LIP OF THE TANK
    AND TAPS IT DOWN WITH A RUBBER MALLET.
    A WORKER NOW TAPS PERFORATED PLASTIC INSERTS
    INTO HOLES IN THE AIR-VENT CHAMBER.
    THESE INSERTS WILL BOTH VENT
    AND FILTER THE AIR FROM THE TANK.
    HE FITS A RUBBER SEALING RING AROUND THE FILL NECK
    AND SCREWS THE CAP ON.
    HE APPLIES ADHESIVE-BACKED DECALS
    TO THE TANK FOR BRANDING PURPOSES.
    HE CAPS THE OIL-INLET TUBE
    TO KEEP CONTAMINANTS OUT DURING SHIPPING.
    HE TURNS THE TANK UPSIDE DOWN
    AND INSTALLS A VALVE ON THE BOTTOM OF THE VENT TANK.
    HE INSERTS A RUBBER O-RING
    INTO A GROOVE ON THE BASE OF THE TANK WALL
    AND TUCKS IT INTO PLACE ALL THE WAY AROUND.
    AFTER EQUIPPING THE FITTINGS ON THE CONE
    WITH CAPS FOR SHIPPING,
    HE INSTALLS THE CONE ON THE BASE OF THE TANK
    AND SCREWS THE RING TIGHTLY TO IT.
    ACCESSING THE TANK FOR MAINTENANCE REASONS
    WILL MEAN UNSCREWING THIS PART.
    THAT COMPLETES THIS RACECAR OIL TANK.
    HOOKED UP TO A SYSTEM OF PUMPS,
    THESE TANKS WILL RECEIVE AND DISPENSE OIL
    SPARINGLY TO IMPROVE ENGINE PERFORMANCE.
    THEY'VE BEEN WELL-EQUIPPED FOR LIFE IN THE FAST LANE.
