  • Laser marking near black graduation marks to aluminium

    2019-07-15

    See full details of this machine at people associate laser marking aluminium as producing an off-white to grey result. By using a high quality 1µm fiber laser with the correct optical configuration it is possible to mark some grades of aluminium near to black without any need for an after mark process.In this trial we marked a tool component with a series of highly contrasting graduation marks in a process time near to 1 minute.Not only was the process reasonably fast but it was also very easy to set-up, the marking process was completely clean and the end result was very aesthetically pleasing.It should be noted that by using a laser of higher power this process can be increased several times faster.

  • India all set to deploy Ap@che Hel!copters at P@k-Chin@ border

    2019-07-15

    In a bid to boost its firepower at the borders, India is planning to deploy its deadly American Apache attack helicopters at the sensitive Pathankot airbase in Punjab as well as Jorhat in Assam to fortify the northeastern sector. The defence ministry cleared a $2.2 billion contract with the US in 2015 for 22 Apache attack helicopters that will strengthen the Indian Air Force’s capabilities on the frontiers with Pakistan and China.“At present, the Air Force is planning to deploy the two squadrons of the Apache helicopters in Pathankot in Punjab and Jorhat in Assam to meet the security requirements of the western and the eastern theatre,” sources in the defence ministry told Mail Today. The Pathankot airbase already has a component of the Russian-origin Mi-35 attack helicopters, which are used for supporting the advance of the Army in war against the enemy infantry and tank regiments while Jorhat would be getting an attack helicopter unit for the first time.The infrastructure for hosting the helicopters in the two bases would also be completed as per the delivery schedule along with the other requirements at these bases. Indian pilots and air crew are also getting trained on the new choppers so that they can operate the helicopters when they arrive in India. The preparation of the Indian crew is also part of the deal that the two sides signed.The Air Force has been flying the attack helicopters for a long time in support of Army’s operations but the land force now wants to control the aerial assets also as it feels that its pilots would be better suited to support operations on the ground. In this regard, the Army is also moving a case for acquiring 11 Apache choppers as part of the repeat order for the ones the IAF is getting. Apache will be the first pure attack helicopter in the Indian forces.The IAF already operates two squadrons of the Russian origin Mi-25 and Mi-35 attack helicopters, which are deployed close to the front lines on the Pakistan border. But these choppers are on the verge of retirement and were designed only to carry troops into heavily defended territories. Equipped with laser and infrared systems for all weather, day-night operability, the Apache fires the Hellfire air-to-air missiles apart from its arsenal of 70-mm rockets and automatic cannon.The twin-engine Apache, operated by two pilots, is capable of detecting 256 moving targets with its doughnut-shaped Longbow radar and engaging them simultaneously. The choppers are scheduled to be delivered in the next couple of years to the Air Force along with the Chinook-64D heavy lift helicopters, which would be used to airlift machinery and heavy equipment in support of troops deployed in high mountainous regions such as Ladakh and the Northeast.India had signed the deals for the Apache and Chinook helicopters simultaneously after a tendering process of almost eight years involving Russian and American firms. The Chinook choppers are planned to be based at the Chandigarh airbase, which is also home to the world’s biggest choppers – the Russian Mi-26, which is used rarely these days for special airlift missions only. The public sector Hindustan Aeronautics Limited is also working on developing the indigenous Light Combat Helicopter in the attack chopper category but it is in a lighter class than the Apaches.The LCH would be built in large numbers by HAL and would be deployed by the Army and the IAF in both the western and northeastern sectors. The HAL has also developed a weaponised version of the Advanced Light Helicopter Dhruv choppers called Rudra, which are getting deployed without much teeth in bases such as Likabali in the Northeast and Bhatinda near Pakistan.

  • Springfield XDS 45 vs Smith & Wesson M&P45 Shield – A Side By Side Comparison

    2019-07-15

    This is a side by side comparison of the Springfield XDS 45 and the Smith & Wesson M&P45 Shield 45. I’ve carried the XDS for 2 years for my daily carry but I am looking at switching to the M&P45 Shield. We will take a look at the features of each pistol and how they compare to each other. To see 230 grain 45 ACP from the M&P45 Shield hitting steel plates in slow motion, click here: Springfield Armory, located in the city of Springfield, Massachusetts, was the primary center for the manufacture of U.S. military firearms from 1777 until its closing in 1968. The site is preserved as the Springfield Armory National Historic Site, Western Massachusetts’ only unit of the national park system. It features the world’s largest collection of historic American firearms.Famous first as the United States’ primary arsenal during the American Revolutionary War, and then as the scene of a confrontation during Shays’ Rebellion, the Springfield Armory in the 19th and 20th centuries became the site of numerous technological innovations of global importance, including interchangeable parts, the assembly line style of mass production, and modern business practices, such as hourly wages. Numerous firearm models produced at the Springfield Armory from 1794 to 1968 were referred to as “Springfield rifles”.In 1974, the Springfield Armory name was licensed to Robert Reese, to form Springfield Armory, Inc., a company that manufactures semi-automatic versions of the M14 rifle and M1911 pistol. The company is not located in or near Springfield, Massachusetts and has no direct association with the original Springfield Armory. The current Springfield Armory, Inc., based out of Geneseo, Illinois, manufactures several of its weapons on the exact blueprints and to identical specifications as the original government owned Springfield Armory. Springfield Armory, Inc. has expanded its line of firearms to include modern day sporting rifles and polymer pistols as well as Historical American icons, namely the M14 and M1911.Smith & Wesson (S&W) is a manufacturer of firearms in the United States. The corporate headquarters are in Springfield, Massachusetts. Founded in 1852, Smith & Wesson’s pistols and revolvers have become standard issue to police and armed forces throughout the world, in addition to their popularity among sport shooters.Apart from firearms, Smith & Wesson has been known for the many types of ammunition it has introduced over the years, and many cartridges bear the company’s name.Horace Smith and Daniel B. Wesson founded the Smith & Wesson Company in Norwich, Connecticut in 1852 to develop the Volcanic rifle. Smith developed a new Volcanic Cartridge, which he patented in 1854. The Smith & Wesson Company was renamed Volcanic Repeating Arms in 1855, and was purchased by Oliver Winchester. Smith left the company and returned to his native Springfield, Massachusetts, while Wesson stayed on as plant manager with Volcanic Repeating Arms.As Samuel Colt’s patent on the revolver was set to expire in 1856, Wesson began developing a prototype for a cartridge revolver. His research pointed out that a former Colt employee named Rollin White held the patent for a “Bored-through” cylinder, a component he would need for his invention. Wesson reconnected with Smith and the two partners approached White to manufacture a newly designed revolver-and-cartridge combination.Rather than make White a partner in their company, Smith and Wesson paid him a royalty of $0.25 on every revolver that they made. It would become White’s responsibility to defend his patent in any court cases which eventually led to his financial ruin, but was very advantageous for the new Smith & Wesson Company.About 2006 Smith & Wesson refocused its marketing on big box retailers, according to Smith & Wesson CEO Mike Golden in a 2008 conference call with investors.In December 2014, Smith & Wesson Holding announced it was paying $130.5 million for Battenfeld Technologies, a Columbia, Missouri-based designer and distributor of hunting and shooting accessories. The company made the acquisition with the eventual intent to merge all its existing Smith & Wesson, M&P and Thompson Center Arms accessories into a single division.In August 2016 the company bought Crimson Trace, a laser-sight manufacturer, for $95 million and Taylor Brands, a tool and knife maker. On November 7, 2016, Smith & Wesson announced that it would be changing the name of its holding company to American Outdoor Brands Corporation.Muzzle First LinksYouTube Channel: Website: Twitter: Facebook: Recent Upload: Most Popular Upload: To Us On YouTube: Muzzle First our goal is to make fun, information and educational videos for the firearms and outdoors enthusiast.

  • I Saw The Sign – Let’s Go Shoot The 642 S&W .38 Special (Airweight J Frame)

    Yesterday YouTube gave me a sign. It said “Shoot The Snubby”. It’s been over a year since it’s been to the range, so I took it to the range with me.
