When using a micrometer to set a dial bore gauge, the accuracy of the measurement will be 0.002 inches or 0.0508 millimeters. A ring gauge can be used to obtain higher accuracy at a higher cost and higher time requirement. When a dial bore gauge is set using a ring gauge, overall accuracy can be within 0.0001 inches or 0.00254 millimeter. [2] A ...
The M1941 Johnson Rifle is an American short-recoil operated semi-automatic rifle designed by Melvin Johnson prior to World War II. The M1941 unsuccessfully competed with the contemporary M1 Garand rifle but was used in limited numbers by the US Marines [ 2 ] during the Second World War.
Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
Metric gauge block set, 112 pcs Another set with 8 pcs, 125 mm - 500 mm Trolley model. Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge ...
Bore gauge: a device used for measuring holes. Hole gauge [3] used to gage internal dimensions of bores that are either too small in diameter for an inside micrometer, and have greater economy than a bore gage or other precision internal gage. Caliper: a device used to measure the distance between two opposing sides of an object.
1927 Johnson Seahorse outboard motor at the Tellus Science Museum. The original company that made Johnson inboard motors and outboard motors was the Johnson Brothers Motor Company of Terre Haute, Indiana, United States. They started building inboard 2-cycle marine engines in 1903 in a barn behind the house, along with matching boats.
Many models of digital indicator can record and transmit the data electronically to a computer, through an interface such as RS-232 or USB. This facilitates statistical process control (SPC), because a computer can record the measurement results in a tabular dataset (such as a database table or spreadsheet ) and interpret them (by performing ...
The M1941 Johnson Light Machine Gun, also known as the Johnson and the Johnny gun, [1] was an American recoil-operated light machine gun designed by Melvin Johnson in the late 1930s. It shared the same operating principle and many parts with his M1941 Johnson rifle and M1947 Johnson auto carbine .
