The splints are narrow metal strips arranged longitudinally, pierced for riveting or sewing to the foundation. Splint armor is most commonly found as greaves or vambraces . It first appears in a Scythian grave from the 4th century BC [ 1 ] then in the Swedish Migration Era ; [ 2 ] and again in the 14th century as part of transitional armour ...
Valve seats are often formed by first press-fitting an approximately cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each eventual valve stem position, [1] and then machining a conical-section surface into the valve seat that will mate with a corresponding conical section of the ...
In Japan, mail and plate armour is called "karuta", small square or rectangular rawhide or metal plates with the gaps between them filled with mail. [9] The first known use of iron plate mail in Korea was used by the Gaya Confederacy between 42 and 562 AD. A large number of iron and steel artifacts, including iron armor, iron horse armor such ...
Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
Seats may be tested against one or more classes and are required to demonstrate that they can usefully reduce the vibration exposure with different weights of seat occupant. There are significant challenges to measuring marine seats at sea, including variable weather conditions, boat availability, operating costs, and personnel safety.
Boats that are bow coxed rely on communication between the bow and the cox - as the cox cannot see boats coming up from behind. The bow pair tend to be the smallest of the rowers in the boat. In an 8 boat, bow pair, strength wise, is where the weaker rowers seat. Although weaker, they have some of the best technique out of the whole boat.
