    Made as part of the WWII war effort by Chrysler, THE BOFORS GUN TEAM shows the manufacture of the Bofors 40mm anti-aircraft gun then in use by the Navy and Army. This was one of the most stunning manufacturing feats of the war, since the Bofors was an extremely intimidating weapon to mass produce and many believed it could not be produced in quantity, in time to make a difference in the war. Within 3 years however Chrysler had shipped over 40,000 complete mechanisms and 75,000 barrels.
    At 1:55, the Swedish-designed gun is seen in its "Americanized" configuration -- made for mass production in a Chrysler factory. At 2:30, new blueprints are made from Swedish originals which were in metric measure. At 2:45, a diagram shows how the manufacture of the gun was split between Dodge, DeSoto, Plymouth and other Chrysler plants. Production lines are seen for breech casings and other parts in the gigantic plants, which were formerly used for automobile manufacture. At 8:55, blocks are shown being made through mass production techniques. At 9:11, quality inspection is made of the blocks. At 13:30, the manufacture of the gun barrel is seen. At 16:20, breech blocks are assembled and tested.
    The Bofors 40 mm gun, often referred to simply as the Bofors gun,is an anti-aircraft/multi-purpose autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well as by the Axis powers. A small number of these weapons remain in service to this day, and saw action as late as the Gulf War.
    In the post-war era the original design was not suitable for action against jet powered aircraft, so Bofors introduced a new model of significantly more power, the 40 mm L/70. In spite of sharing almost nothing with the original design other than the calibre and the distinctive conical flash hider, this weapon is also widely known simply as "the Bofors". Although not as popular as the original L/60 model, the L/70 remains in service, especially as a multi-purpose weapon for light armored vehicles, as on the CV 90.
    In order to supply both the Army and Navy with much greater numbers of the guns, Chrysler built 60,000 of the guns and 120,000 barrels through the war, at half the original projected cost, and filling the Army's needs by 1943. Over the lifetime of the production, their engineers introduced numerous additional changes to improve mass production, eventually reducing the overall time needed to build a gun by half; most of these changes were in production methods rather than the design of the gun itself.York Safe & Lock also produced the weapons, though its attempts to coordinate drawings across the program were unsuccessful, and this responsibility was transferred to the Naval Gun Factory in July 1943.There were many difficulties in producing the guns within the United States, beyond their complexity (illustrated by the use of 2,000 subcontractors in 330 cities and 12 Chrysler factories to make and assemble the parts).

    Chrysler must have pulled a lot of strings to completely write the York Safe and Lock Company out of this film. It was York that sent employees to Sweden in the late 30s to obtain the license to manufacture, York that arranged for the Navy to purchase said license (N557a-2) in 1941, and York that won the Navy contract do the metric-US conversions and redesign for the guns. Chrysler was brought in by the Army, and was mainly tasked with ensuring their drawings matched what York came up with. Chrysler did phenomenal work when it came to speeding up production, but to simply say the Navy mounts were produced by various manufacturers at 18:55 is to leave out the company that was most responsible for the Americanization of the Bofors gun.

    In Bofors defense I have to say that their production methods were probably more than adequate to meet customer demand in the peacetime prior to WWII and Bofors probably chose lots of hand fitting because of the economics, specialty machine tools are expensive. Chrysler repurposed multiple automobile factories and all the machines in them to pull off the amazing job of ramping up production.

      From Wiki:
      Mid-Atlantic English was the dominant dialect among the Northeastern American upper class through the first half of the 20th century. As such, it was popular in the theatre and other forms of elite culture in that region.
      With the evolution of talkies in the late 1920s, voice was first heard in motion pictures. It was then that the majority of audiences first heard Hollywood actors speaking predominantly in Mid-Atlantic English. Radio announcers copied it.

    In this video, we see the engineers converting blueprints from metric to imperial, and there is an interesting little detail about this, and the manufacturing of Bofors guns in the USA;
    it wasn't really properly licenced... which makes me wonder where the blueprints came from. However, as the war progressed, the USA put an embargo on war materials, including
    the Pratt & Whitney R-1830 Twin Wasp, which Sweden wanted to use in a number of existing, and planned aircrafts. In need of these engines, swedish engineers, re-engineered the
    blueprints, metallurgy, and manufacturing from a few test examples of this engine that had been brought over to Sweden before the embargo. It was then sucessfully manufactured
    in quantity under the name STWC-3. Some still fly today.
    I have been told that the governments in both countries after the war, look at these two instances of "breeching the protocol", shrugged and called it even.

    Like almost everything built in the US the production of this gun owes its precision of parts manufacture to US automotive "Production Engineering". Were in all components are made to an exacting tolerance standard being mirror images of one another and require no "fitting" in order to be mounted, or swapped between end items. Something the world at this time, even the fastidious Germans were not doing in any produced item at that time. This allowed any machining manufacture to produce any item as long as they followed the production engineering methods and standards set forth.

      The first product whose entire parts were interchangeable, were muskets made by gunsmith Honore Blanc in Paris in 1790.
      Bewilderingly, after producing 10,000 muskets a year for Napoleon, in 1806, the French government decided to reject this innovation, and return to the old craftsmen method of gun manufacture.

    • @ditzydoo4378

      @@clark9992 Attempts at interchangeability of parts can be traced back as far as the Punic Wars through both archaeological remains of boats now in Museo Archeologico Baglio Anselmi and contemporary written accounts. In modern times the idea developed over decades among many people. An early leader was Jean-Baptiste Vaquette de Gribeauval, an 18th-century French artillerist who created a fair amount of standardization of artillery pieces, although not true interchangeability of parts. He inspired others, including Honoré Blanc and Louis de Tousard, to work further on the idea, and on shoulder weapons as well as artillery. In the 19th century these efforts produced the "armory system," or American system of manufacturing. Certain other New Englanders, including Captain John H. Hall and Simeon North, arrived at successful interchangeability before Whitney's armory did. The Whitney armory finally succeeded not long after his death in 1825.

    How funny... At 1:07: as they are introducing the “Bofors 40mm Anti-Aircraft Automatic Canon” they shift to an overhead view.... Of the Quad 1.1” AA Mount, or “Chicago Piano.”
    Oddly, the 1.1”/75 Automatic Canon, was intended to be used as a single-gun, replacing the M2 .50 Machine-Gun as a “Light Anti-Aircraft Canon,” rather than the “Medium AA Mount” it eventually became.
    The original specifications from the Navy called for a “Machine-Canon” of 25mm to 30mm that had a Rate-of-Fire similar to that of the M2. A RoF that was never even remotely achieved by a single-gun. It required 4 of the guns to achieve the same volume of fire as a single M2. As such, it became an intermediate AA Weapon, while the 20mm Oerlikon Canon eventually replaced the Water-Cooled M2 Machine-Gun as the Light AA outfit of Ships.
