Re-crown damaged muzzles on a lathe. Repair dented shotgun barrels. Install (solder) or repair rib on shotgun barrels, or repair double-barrel assemblies. Measure and correct head-space dimensions. Check for excessive bore erosion. Troubleshoot and repair feeding, ejecting and firing problems.
Woodturning is the craft of using a wood lathe with hand-held tools to cut a shape that is symmetrical around the axis of rotation. Like the potter's wheel, the wood lathe is a mechanism that can generate a variety of forms. The operator is known as a turner, and the skills needed to use the tools were traditionally known as turnery.
This is a problem in many manufacturing processes, especially the firearms industry: the barrel of a gun must be very straight and accurately sized. Gun barrels are far longer than their inside diameter; as an example, the .223 inches (5.7 mm) caliber barrel of the M16 rifle is 20 inches (510 mm) long, nearly 90 times the diameter of the bore ...
Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate jewelry.
A crown may be re-cut with relative ease, and this can fix any problems caused by a defective or damaged crown, by ensuring an even release of the bullet. [42] An 11 degree crown has the best accuracy potential, and should be applied to a barrel to get the best gas flow at the bullet exit point of the barrel.
The “Barrel House,” a home made out of a pair of two-story tall reclaimed redwood wine barrels in Big Sur, is on the market. And it can be yours for only $3.265 million. This architect ...
Rifling of a 105 mm Royal Ordnance L7 tank gun Conventional rifling of a 90 mm M75 cannon (production year 1891, Austria-Hungary) Rifling in a GAU-8 autocannon. Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy.
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits. The term single-point diamond turning (SPDT) is sometimes applied, although ...
