For those who don't like MIM parts, you're REALLY going to be upset in the future! In just a few years PRINTED steel, aluminum, plastic, and even HUMAN TISSUE "parts" will replace damn near every other form of production!
Just a year ago a human trachea was "fabricated" by "printing" the equivalent of a cartilagenous structure, bathing it with stem cells taken from the patient's own bone marrow, then "percolated" in a primordial bath until tissue overgrew the polymer structure and differentiated into tracheal cells...the patient's tracheal cells. This completely fabricated trachea was then implanted - replacing one that was almost fully obstructed by a large tumor that had destroyed the man's vocal cords. With the new trachea he was able to talk....he is not on rejection drugs...he now has a new trachea that is functionally all HIS...thanks to modern technology. I wonder how many who despise "new" technology would refuse to have THEIR life saved by its application?
Just a few weeks ago I'm sure we ALL read about the company in Texas that printed an ENTIRE 1911 save for the springs as a "proof of tech" example of where current PRINT fabrication is. Even Hershey's is getting into the act...they will soon be "printing" candy in shapes that could not be created any other way.
Even now a research MD is working on "printing" human kidneys and livers...complex organs in drastically short supply, but more, a PRINTED version means no rejection of tissue...the resultant organ is YOUR organ! His company has already demonstrated "printed" heart valves.
MIM is "OLD" technology...been around for many decades and requires complex development of forming equipment...bulk handling of metal, excessive heat input..specialized dies, etc. PRINTED components means high-energy lasers target just the right heat to cause tiny amounts of steel to be molecularly bonded, building up the item in a matter of minutes.
When the M-16 appeared all the "gun" people of that era despised it for being aluminum and plastic...but clearly the LAST LAUGH is on them...as it has been around now for over 50 years and everything "new" coming along is nothing very different than an external, cosmetic flavoring of the same core device.
When the Glock came along all the "gun" people despised it for being plastic..."cheap"...not durable compared to good old STEEL! Yet, the Glock has proven to have a LONGER service life with HIGHER rounds count than any other autoloading pistol! Glocks - with their puny "slide tabs" instead of rails, have proven to be STRONGER when it comes to handling top loads than their "all steel" counterparts...so much for that "cheap plastic" nonsense.
On the car subject...I grew up in the 60's and 70's and remember WELL how much time was spent keeping those *** junkers running! POINTS ignition...WEAK and unreliable, requiring near constant readjustment and a spark so poor the plugs required near constant resetting...cleaning, and replacement. Carburators made so shoddily that within 20K miles of "new" the seals all leaked...manifold gaskets leaked...floats leaked and floated...manual "timing" that had to frequently checked and REset. "May-pops" for tires...blowouts were COMMON due to poor design, WORSE manufacturing quality control, and lack of TECHNOLOGICAL knowledge of how to make tires that hold up. Rusted out panels... dull paint on cars only a few years old - or less, non-existent mileage...clunky, out-of-spec drivetrains, transmissions that were lightyears out of "bluprint" with leaking seals, mechanical servos, slipping torque converters...interior components that bleached out within a few months...lots of good old american STEEL interiors that guaranteed a BRAIN INJURY in a crash...seat belts only appeared after being mandated and even then, poorly designed passenger compartments, non-reinforced, "hand-welded" structures...weak, "body-on-frame" designs that were heavy yet did nothing to enhance strength and survivability....oh yeah...the GOOD OLE' DAYS! They sure don't build 'em like they used too do they!
No...they build them BETTER...LIGHT YEARS BETTER and they do it by application of modern technology...now a new car is still virtually new even five years later...or more. "Tune ups" are a thing of the past...spark plugs last for over 100K miles...ignition systems that provide 3x the spark energy, fuel injection...no more flooded, leaky carbs...significantly improved fuel economy, and HIGHER horsepower! The average crossover SUV today has MORE horsepower, better gearing, and accelerates faster than did the vaunted 1970 Corvette LT-1! Tires that actually provide traction...don't blow out very often...even when holed by a nail you don't even know it by other than a slow leak. Far safer...can cruise at higher speeds, still get better mileage, and the paint stays shiny...mufflers go for the expected life of the car...loads of airbags, energy absorbing structures designed to SAVE YOUR LIFE...not catapult you into a steel dash, a steel wheel, a steel wheel post, a STEEL roof and a massive windshield! Restraint designed to actually WORK...Oh, and modern cars are LESS EXPENSIVE based on adjusted dollars due to superior manufacturing TECHNOLOGY!
In fact, modern GUNS are less expensive than they used to be for the same reason! I paid over $400 for a Randall 1911C back in 1984...I'm about to pick up a new RIA 1911 for a piddling $329....30 years later...paying LESS for an almost identical "type" of gun!
Back in 1984 the cost to build your own AR-15 was virtually the same as today...except that means today's builds are CHEAPER!
As for all this nonsense about the quality of the old guns...they couldn't have built the .460 and .500 magnum in 1970...because they lacked the ability to use computer design, computer simulation, and computer manufacturing to produce EXACT parts that contain 65,000 pounds per square inch of pressure...anyone who knows guns and examines a modern Smith .460 or .500 has to marvel at the "little things" they did to make these guns work...UNHEARD OF...UNDREAMED OF in 1975! Anyone ever stop to think that there is such a thing as TOO CLOSE tolerances for certain aspects of a gun's function? A precisely designed firing pin and firing pin hole is crucial to containing massive magnum pressres, yet except for the specific points of needed contact, the crane-to-frame interface is BETTER served by have some gap! A major weakness of any revolver with a hairline crank-to-frame mating is a tiny grain of unburned powder or powder residue can cause the failure to lock the cylinder into place and so the hammer cannot actuate. The "tighter" the clearances around the forcing cone the HIGHER the pressures exerted during firing...a .001" here and there can dramatically reduce high-speed gas cutting...meaning a LONGER life...
It hurts a lot of "feelers" to hear the AR-15 is SUPERIOR to the vaunted M1 Garand and the half-baked retread version that became the M-14...The Garand was "The finest battle implement ever devised" in 1936...huge, HEAVY, LONG, poor quality castings that were universally out of spec, WOOD furniture that rots under combat conditions. Long, barrel with piston situated way at the front working AGAINST accuracy...a puny 8 round capacity of an overly huge cartridge that worked AGAINST the Infantryman's purpose. An "en bloc" clip that was the cat's meow back then but was fumble-prone to load, and could actually injure the USER if not perfected! The M-14...same gun just freshened up...rottable wood...same accuracy robbing piston system, detachable box yes that still glomed onto the notion of an overly powerful cartridge that limited the individual's ability to carry enough ammo. Plenty "jam prone" in it's own right...in FACT, had the M-1 been pressed into service along the same time-frame as was the "prototype" M-16 it would have been a dismal failure! But the Army LOVED it...so they ignore it's faults.
Both require time consuming, "expert" fitment...headspacing is time-consuming and INDIVIDUALIZED meaning NON-Standard! Barrels requiring massive torque...each part requiring "expensive" time-conuming expertise to assemble into something that MIGHT function, but will probably require more refinement to get it just right.
Meanwhile, the M-16 family is LIGHT YEARS better...factory fitted barrel extensions that mate with virtually ANY bolt...low-torque barrelling...EASY, no "expertise" required. LIGHT weight..."plastic" furniture that does NOT rot and holds up just fine. The best ergononomics of ANY modern rifle bar none...which is why the design is COPIED BY ALL who seek to claim they've "improved it" when all they've done is COPY it with a few custom doo-dads! But then again, they CAN do that because the gun is fully MODULAR thanks to being designed by an actual engineer who started clean sheet and not by copying the *** that came before it. The M-14 had a service life of barely a decade...and despite all the intentional sabotage of the M-16, it survived...survived deliberate procurment of out-of-spec magazines, troops told NOT to clean it...even the A2 redesign with the addition of an excessively thick barrel, unecessary 800 meter sight, and ridiculous burst feature couldn't kill it. Chopping the barrels ever shorter then blaming it for lacking power...yet it motors on, PROOF of it's superior basic engineering and design to the point where today there is a HUGE popular interest in owning a civilian version...so much so that S&W copied the design...so too did HK, and Sig, and a billion "custom" makers...
All the traditionlists love to harp about the inferiority of "ZAMAK" firearms...a Zinc-aluminum alloy that turns out to mighty tough and durable, yes, a bit heavy due to the Zinc but plenty adequate for the application while saving money.
Those wonderful M-1's (civilian M-14) keep going UP UP UP in price while the M-16 family keeps coming DOWN DOWN DOWN...why? Because the M-1 is OLD tech requring far too much handling of parts to complete thus driving costs through the roof. The AR-15 requires virtually NO "precision fitment" of parts...there are VERY FEW points where machining has been performed after the part was initially manufactured...resulting in low labor cost and ease of both assembly and maintenance.
And as for all the hooey about how "formed metal" parts will never measure up to the strength of forged...a bit of metalurgical education is in order. When you start "building" steel up from the molecular level you actually ENHANCE the ability to modify it for specific applications.
Oh...and here is another example of how "they build 'em BETTER than they used too..." SWORDS...the common bullhead certainly presumes the authentic, original, 17th century "Nihonto" is superior in every way to ANYTHING made today...yet as with most things...they're wrong!
All the hoopla surrounding the way swords were made being about a superior process is REAL because they LACKED the ability to do what can be done today! They had to find iron in the form of "black sand" which they threw into a fire and heated to melting...and since they used charcoal to heat, what do you know...CARBON was introduced onto the surface and someone noticed it created a "carburized" surface...so then someone else thought...hmmm...maybe if I hammer sections that have carbon-coated surfaces together I can introduce the benefits of surface hardness throughout the "iron"...and thus "steel" appeared by being hammered and folded to "blend" carbon into the iron to create the alloy we know as steel. (I'm sure someone back then was carping about how that new-fangled steel was total **** compared to good 'ole iron because it took time to figure out how to harden and temper the new-fangled alloy, but once they did....pure iron was OUT!)
Then, they figured out that if they coated the bulk of the blade with clay when they hardened it the clay-coated section would be somewhat softer yet the edge would be quite hard. Those old Nihonto (Katana) weren't hardened and tempered to a "spring" steel...a folded blade can't be. The were the BEST that could be made by that technology, but then comes a dude named Bessemer who figured out how to make HUGE amounts of steel with precise alloying capability. Today, precisely alloyed, SUPER HIGH quality steel of a KNOWN carbon content is CHEAP and easy to make. A modern sword made from a single "block" of 1095, or 9260 steel is LIGHT YEARS BETTER than anything made in Japan in the 17th century. A modern "monosteel" blade can cut harder without breaking...is "spring tempered" meaning they can be bent nearly 90 degrees without breaking yet spring back to "true." Due to the superior, even distribution of carbon atoms within the iron matrix, they can be hardened to create a superior cutting edge, yet tempered to retain a "softer," malleable spine/core that can absorb the shock of blade-on-blade combat. Yet...one can purchase a sword superior to ANYTHING from ancient Japan for just a few hundred bucks...actually for less than a hundred bucks when we're only talking the quality of the steel and not all the "atistic" **** that goes into a top drawer Katana. A modern steel sword makes anything that ever came out of Toldedo Spain look like dog excrement yet back in their day, Spanish steel was the bomb!
Look at Tig welds...heat control so precise even under radiological examination the weld area is indistinguishable from the base area! We've all heard about how "rewelded" receivers are junk...not to be trusted (M1/M14) yet if they are Tig welded properly they are equal too or STRONGER than their parent metal! That is MODERN TECHNOLOGY in action!
The point is...we are immersed in technology. Technology is what has made this world...what keeps this world funtioning. And yes, technology has made our lives BETTER...across all areas including the manufacture of firearms. It will be TECHNOLOGY that will allow future generations of firearms enthusiasts to retain THEIR 2nd Amdt rights by being able to upload a file and then "print" a gun that is fully functional rendering future legislation designed to thwart private possession ridiculously moot!
