Brilliant Video From Beretta about Gun-Making

Beretta shotgun technology robot video Human

Here’s a really great video about firearms crafting produced by Beretta, a legendary Italian gun-maker. This movie, entitled “Human Technology”, is one of the best videos we’ve ever featured on this site. It’s that good. You’ll see an amazing blend of ultra-modern manufacturing technology along with old-world artisanship — “a mesmerizing meld of the high-tech and the traditional”. (Daniel Xu, Outdoor Hub.)

“Human Technology is a singular and symbolic movie, its cast entirely made up of Beretta workmen, thus illustrating the perfect synthesis between craftsmanship and technology,” Beretta writes. This artistic movie by Ancarani Studio illustrates all the aspects of the manufacturing of a high-end Beretta shotgun. This video is a study in contrast. The movements of robotic assembly machines are juxtaposed with the centuries-old craftsmanship of stock carvers. Beautifully filmed and edited, this video should amaze and entertain anyone who loves fine firearms. (Full-screen HD Recommended.)

Barrel-Making: How Ruger Crafts Hammer-Forged Barrels

Ruger Firearms Barrel Making Hammer Forging
This image shows a barrel in the process of hammer forging. Watch this operation starting at 1:15 in the video linked below.

You have probably heard the term “hammer-forged barrel”. But do you know how the cold hammer-forging process works? In this interesting video from Ruger, you can see the full barrel making process, including cold hammer-forging on a massive machine. Watch long rods of steel barrel material get cut to length, then drilled. After that Ruger uses CNC machines to contour the barrels before hammer forging.

Anyone with an interest in barrel-making should watch this video:

As the barrel is cold hammer-forged, a giant machine literally pounds the barrel from all sides around an internal carbide mandrel, which forms the rifling inside the bore. The actual hammer-forging is illustrated starting at 1:15 in this video. Through the process of cold-working the barrel around the mandrel, the barrel ends up with a longer length, a smaller outside diameter, and a higher hardness.

Ruger Firearms Barrel Making Hammer Forging
Before hammer forging, the barrels are deep-hole drilled, four at a time, with a bit that is slightly larger diameter than the caliber planned for the barrel.

Following the drilling, the barrel rod is placed in CNC machines to be turned down to the correct outside shape and size and both ends are trimmed.

Timney Triggers Made with State-of-the-Art Automated Machinery

Timney Triggers Factory Tom McHale Scottsdale Arizona CNC

For years, Timney triggers have been popular drop-in upgrades for hunting rifles, rimfire rifles, and AR platform rifles. To meet the demand for its many trigger products, Timney Triggers has expanded its operation, adding state-of-the-art CNC machines and other high-end, automated equipment. A far cry from the dank gun factories of the 1950s and 1960s, Timney’s Arizona production center now resembles the squeaky-clean, ultra-modern facilities where electronics are assembled.

Today’s Timney factory is all about computerized automation. Timney Triggers’ owner John Vehr states that it would take 60 or more trained machinists and metal-workers to produce as many triggers as can Timney’s modern machines. Timney does employ two dozen workers, but they are assigned tasks that the computerized machines can’t do as well or better.

If you want to see how Timney triggers are made this days, check out Tom McHale’s recent account of his visit to the Timney Factory in Scottsdale, Arizona. McHale explains how the triggers are designed and fabricated, and 20 high-rez photos illustrate the production process and machinery.

Forum Member Builds His Own High-Quality Front Rest

AKShooter front rest F-Class Dasher 6mm Alaska
AKShooter front rest F-Class Dasher 6mm Alaska

AKShooter front rest F-Class Dasher 6mm AlaskaYou have to admire someone with serious do-it-yourself skills. Not just hammer and nail skills, but formidable design and fabrication skills. Well Forum Member Dave D. (aka “AKShooter”) has a DIY skill set that might put some trained machinists to shame. You see, “DIY Dave” crafted his own pedestal front rest from scratch, using his own design and about $100.00 in materials (not counting the Edgewood front bag). Dave estimates he put 20 hours of labor into the project, but the end result was worth it: “This Do-It-Yourself rest drives like a dream. I’ve played with the Caldwell and a Sinclair, they have nothing on this one.”

Dave tells us: “Here is my Do-It-Yourself front rest. I wanted to show other folks who are handy that a solid front rest is doable with a bit of time — and you don’t need to spend $1000.00. (You could say this is a design for shooters with more time than money.) This is for F-Class. I was originally overwhelmed by the equipment needed, so I decided to make my own rest. I didn’t have the money for a SEB or Farley Coaxial. This is what I’ll run this season (my second as an F-Class competitor).”

Tech Trends: Precision Barrel Bore-Honing

Some custom barrel makers are now honing barrels (after drilling) to improve bore diameter uniformity, smooth the interior finish, and reduce barrel lapping times. For years, large-scale manufacturers of hammer-forged barrels have employed honing. Now the process is being used by smaller, “boutique” barrel-makers. This article explains how and why barrel honing is done. Take the time to watch the video. For anyone with an interest in barrel-making, this video is an eye-opener…

Barrel Honing Process Demonstrated (Worth Watching!):

Barrel Bore honing cut-rifled rifling hammer forging accurateshooter.com

For custom barrel makers, honing is a time-saver and cost cutter. A few minutes on a honing machine can cut lapping times in half, leaving a cross-hatched surface finish in single or low double-digit Ra. Honing is the same process used to make diesel fuel injectors with bore roundness and straightness controlled to fractions of a micron (<0.000040"), with surface finish Ra ≤0.15 µm (6 µin).

A key manufacturing process used for hammer-forged barrels is now getting attention from the makers of custom button-rifled barrels. This process is precision bore-honing. Honing produces a high-quality bore surface fast, which is critical to hammer forging. (Why is honing so important with hammer forging? Surface finish is the one feature of the barrel that cannot be controlled in hammer forging. Surface imperfections in a barrel blank tend to be amplified as the blank is formed on the rifling mandrel. And if the bore is chromed afterwards, imperfections in the surface finish become even more obvious.)

Honing dramatically improves bore diameter size uniformity and accuracy, surface finish and roundness throughout the length of the barrel. It can certainly be used in place of a pre-rifling lap. The chief difference between a lapped and honed bore is the direction of the finish lines in the bore. Honing leaves fine spiraling crosshatch lines, while a lap leaves lines going longitudinally in the bore. After rifling the manufacturer can remove the crosshatch finish with a quick lap if desired. Honing is fast, accurate, and can be automated. Its surface quality and geometry can duplicate lapping, except for the longitudinal lines of the lapped finish.

Frank Green of Bartlein Barrels told us: “We worked with Sunnen and we did all the initial testing on the prototype machine for them. The machine works great! We ordered and received last year a new manufactured machine with the changes we wanted on it and we just ordered a second one a month or so ago. Should be here next month.”

Computer-Controlled Bore-Honing
Honing can be done with great precision through the use of advanced, computer-controlled honing machines. Sunnen Products Company recently introduced a new machine for .17 to .50-caliber barrels (see control panel below). The spindles on this machine can correct bore size imperfections so small only an air gauge can measure them. The consistency this allows improves bore uniformity, which, in turn, produces more accurate barrels for the precision market.

How Barnes Bullets Are Made — Views from Inside the Factory

Barnes Bullets FactoryMany of our readers have been interested in learning how modern bullets are made. While a “boutique” bullet-maker, supplied with appropriate cores and jackets, can craft bullets using relatively simple hand dies and manual presses, factory production is different. The major bullet-makers, such as Barnes, employ huge, complex machines to craft their projectiles on an assembly line.

Modern hunting bullets are made with a variety of sophisticated (and expensive) machines, such as Computer Numerical Control (CNC) lathes, giant multi-stage presses, and hydraulic extruding machines that draw lead ingots into lead wire. Barnes offers an “inside look” at the bullet production process in a series of videos filmed at its Mona, UT factory. We’ve embedded four videos from the series here. These videos can also be viewed on the Barnes Bullets YouTube Channel.

Milling Slots in TSX All-Copper Bullet
This video shows how the slots (between the drive bands) in the TSX all-copper bullet are cut. The slots reduce the bearing surface that contacts the rifling. This helps reduce friction and heat, extending the life of barrels used with all-metal, drive-band bullets:

Varminator Bullets Produced in Jumbo Transfer Press
Here is the transfer press used in the production of Varminator and MPG Bullets. The process begins with a giant spool of flat copper material. The copper is stamped into jackets and eventually the formed Varminator bullets are ejected one by one into a bucket.

CNC Lathe Turns Bullets Automatically
In the video below, a Bar-Feed CNC crafts mono-bloc bullets from metal bar stock. Barnes uses a small CNC lathe to turn .50-caliber bullets from brass bar stock. We’re not sure which bullet is being made in this video. The material looks to be sintered metal. In the close-ups you can gold-colored shavings from when the machine was previously used for CNC-turned brass bullets.

Accuracy Testing in 100-yard Tunnel
Barnes regularly tests bullet samples for accuracy. In the video below, a Barnes technician loads sample rounds and tests them for accuracy in a 100-yard tunnel. The rounds are shot through a special fixture — basically a barreled action connected to parallel rods on either side. This allows the testing fixture to slide straight back on recoil (see it move back at 1:07-08 minute mark). Note how the tester actuates the trigger, which is oriented upwards, just the opposite of a normal rifle. The technician taps the upward-pointing trigger shoe lightly with a metal rod. Could this upside-down trigger orientation be useful in benchrest shooting — perhaps with railguns? It could make for an interesting experiment.

Future Tech: 3D Metal Printing of Gun Parts and 1911 Pistol

Could your next metal scope rings, trigger guard, or muzzle brake be crafted with a 3D printing process? It’s possible. In fact, a wide variety of metal parts (even a complete handgun) can be printed using the latest 3D Direct Metal Laser Sintering (DMLS) process. The way this works is as follows: powdered metal is heated by a laser, causing the metal particles to fuse and solidify. This is progressively repeated, in vertically-stacked layers, until the entire metal part is complete. It’s like building a metal layer cake with the shape/size of each thin layer defined by a precise laser beam. The laser is guided by computer-controlled servos following a CAD “blueprint”.

This video demonstrates how metal parts are 3D printed using the DMLS process. This technology is offered by Solid Concepts, a leading rapid prototyping and manufacturing services company.

The Solid Concepts 1911 — World’s First 3D-Printed Metal Firearm

Solid Concepts has manufactured the world’s first 3D-printed metal gun using a laser sintering process and powdered metals. The gun, a .45 acp 1911 clone, has already handled 50 rounds of successful live-fire testing. A 1911 design was chosen because the “blueprint” is public domain. The gun is composed of thirty-three, 17-4 Stainless Steel and Inconel 625 components, crafted through the DMLS process. Even the carbon fiber-filled hand grips are 3D printed, using a Selective Laser Sintered (SLS) process.

3D metal printing 1911 DMLS Solid Concepts

Except for the springs, all the parts of this 1911 handgun were printed using the metal laser sintering process. Yes even the highly-polished slide, the barrel, the frame, and the hammer were printed. There are no forgings, castings, or conventionally-machined parts. With the exception of springs, all 30+ components in this prototype pistol were printed using Direct Metal Laser Sintering (DMLS) technology. Watch the video for a glimpse into the future of gun-making:

World’s First 3D-Printed Metal Gun Test Firing

Solid Concepts believes that its fully-functional, 3D-printed 1911 handgun proves the viability of 3D printing for gun parts, even highly-stressed components. Kent Firestone, V.P. of Additive Manufacturing at Solid Concepts, states: “We’re proving this is possible, the technology is at a place now where we can manufacture a gun with 3D metal printing. And we’re doing this legally. In fact, as far as we know, we’re the only 3D printing service provider with a Federal Firearms License (FFL). Now, if a qualifying customer needs a unique gun part in five days, we can deliver.”

3D metal printing 1911 DMLS Solid Concepts

Will we see complete 3D-printed metal guns on the market soon? That’s unlikely. It’s still more economical to produce complete guns the old-fashioned way. However, we may see 3D printing used for rapid prototyping. In addition, 3D metal printing has advantages for hard-to-machine parts with complex geometries. Solid Concepts reports that its 3D printed metal has fewer porosity issues than an investment cast part and better complexities than a machined part. It will be interesting to see what unfolds in the years ahead.

Shilen Custom Rem 700 Clone Actions and Complete Rifles with Savage-Style Barrel Nut System

Did you know that Shilen Rifles Inc. offers barreled actions and complete rifles? And that Shilen offers a Savage-style, barrel-nut system for its Rem-clone actions? Starting in 2010, after a hiatus of nearly twenty years, Shilen returned to the rifle manufacturing market. After several years of development, Shilen now offers custom actions ($950.00), barreled custom actions with triggers ($1500.00), and complete rifles ($3200.00 and up).

The new Shilen custom actions are CNC-milled from high-grade stainless steel. Two types are offered — the multi-shot DGR (Repeater) or the single-shot DGV (Varminter) action. Both actions will be offered in most common bolt faces and both right-hand and left-hand actions are immediately available. The DGR and DGV actions have a 1.350″ diameter with 8-40 scope base mounting screw holes, and an 0.300″ pinned recoil lug. The spiral-fluted bolts feature a floating bolt head with an interchangeable bolt handle knob. These actions feature a footprint similar to the Remington Model 700. Both DGR and DGV actions will accept many aftermarket components crafted for Rem-700 style actions, including triggers and bottom metal.

Shilen Actions Complete rifles

Barreled Actions with Barrel-Nut System for Easy Barrel Exchanges
Along with the stand-alone DGR and DGV actions, Shilen is offering barreled action assemblies, chambered and ready to drop into Rem 700-inletted stocks. The actions are fitted with Shilen match-grade barrels and Shilen triggers. The barrels feature a 1-1/16″x20 barrel thread and are attached to the action by a barrel nut. This Savage-style barrel nut system simplifies headspacing, allowing easy swapping from one barrel to another. With the simple barrel-exchange procedure, you can shoot multiple chamberings with a single action/rifle. For example, shooters can change from a .223 Remington to a .204 Ruger or a .22-250 to a 6mm BR in a matter of minutes.

Complete Rifles with McMillan Stocks
With Shilen’s complete rifles, buyers can choose their chambering, and select barrel and stock configuration. Shooters can choose between a sporter weight wood stock or a variety of McMillan fiberglass stocks. With all complete rifles, the entire package is delivered in a quality gun case and Shilen even includes table mat, cleaning rod, bore guide, jag, bore brush, and cleaning patches.

There has been a strong demand for Shilen’s barreled actions and complete rifles. Accordingly, the waiting period is two to four months for complete rifles, a bit less for barreled actions. But some chamberings can be had much more quickly (if Shilen has a pre-chambered barrel in current inventory). If you’re interested, call (972) 875-5318 or email comments@shilen.com for more info.

Beyond .50 BMG — The Jumbo .950 JDJ

Are you bored with your “whimpy” .50 BMG? Looking for something with a little more punch? Well J.D. Jones and his team at SSK Industries have created a truly big boomer — the .950 JDJ. As its name implies, rifles chambered for the cartridge have a bore diameter of 0.950″ (24.13 mm). This would normally make such rifles “destructive devices” under the 1934 National Firearms Act (NFA). However, SSK obtained a “Sporting Use” exemption allowing the rifles to be sold without special restrictions as destructive devices. CLICK HERE to watch .950 JDJ being fired.

.950 JDJ Specifications
Rifle Cost: $8000.00
Ammunition Cost: $40.00 per round
Projectile Weight: 3,600 grains (more than half a pound)
Rifle Weight: Between 80 and 120 pounds
Muzzle Energy: 38,685 ft/lbs (52,450 Joules)
Momentum: 154.1 Newton-seconds

As crafted by SSK Industries, .950 JDJ rifles use McMillan stocks and very large-diameter Krieger barrels fitted with a massive 18.2-lb muzzle brakes. The ammo produced by SSK features solid 3,600 grain bullets and CNC-machined cartridge brass. It is also possible (through a lot of work), to use a 20mm cannon casing shortened and necked-down.The primer pocket is swaged out to accept a .50 cal machine gun primer. That 3,600 grain bullet is just massive — it weighs more than half a pound. The cartridge propels its 3,600 grain bullet at approximately 2,200 fps. This yields a muzzle energy of 38,685 ft-lbs and a momentum of 154.1 Newton-seconds. The energy on target (knock-down power) is comparable to WWI-era tank rounds.

Robotic 5-Axis Milling Machine Crafts Guns

Terminator RobotRise of the Machines? Well the latest Terminator movie, Terminator Salvation, was recently released, but we don’t think we’ll be facing a world dominated by evil robots anytime soon. Nonetheless, programmed automated milling machines are getting smarter and more capable than ever.

Here’s a remarkable video clip demonstrating state-of-the art CNC production of precision gun parts. In the video, created by STAMA America, an HK pistol gun breech is crafted from bar stock through a totally automated drilling/milling procedure. The breech is made by STAMA’s Model MC 726 MT, a unique five-axis, CNC milling/turning center. The five-axis machine is designed for continuous production of complex parts from bar stock and multiple different parts, including weapon components. CLICK HERE to play 5-minute YouTube Video.

The process shown in the 5-minute video actually takes 50 minutes to craft the breech, starting with a 60mm diameter section of 42 CrMo 4 steel. Amazingly, the 5-axis machine employs 25 separate tools in the operation!

STAMA states that its milling/turning machines “can produce even short runs of complex weapon parts in one operation with superior quality, finish and cost efficiencies. Typically, the Model MC 726 MT can result in up to 70% reductions in part processing time[.]”
