Comparison of .577 Black Powder Express, .303 British & 8 bore bullets. The most common 8 bore cartridges used paper cases, much like shotgun shells, and true .835 in (21.2 mm) caliber projectiles. A larger version utilising a thin brass case was also available, although it fired .875 in (22.2 mm) projectiles, in reality making it a 7 bore. [5]
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 ...

Re-sawing is the splitting of 1-to-12-inch (25–305 mm) hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a 10-foot-long (3.0 m) 2×4 (1 + 1 ⁄ 2 by 3 + 1 ⁄ 2 in or 38 by 89 mm) into two 1×4s (3 ⁄ 4 by 3 + 1 ⁄ 2 in or 19 by 89 mm) of the same length is considered re-sawing.
The 4 ft 6 in (1,372 mm) track gauge, also called the Scotch gauge, was adopted by early 19th century railways mainly in the Lanarkshire area of Scotland. It differed from the gauge of 4 ft 8 in ( 1,422 mm ) that was used on some early lines in England .
The older United States Standard Gauge is based upon 40 lb per square foot per inch thick. Gauge is defined differently for ferrous (iron-based) and non-ferrous metals (e.g. aluminium and brass). The gauge thicknesses shown in column 2 (U.S. standard sheet and plate iron and steel decimal inch (mm)) seem somewhat arbitrary.
A 12-gauge shotgun, nominally 18.5 mm (0.73 in), can range from a tight 18 mm (0.71 in) to an extreme overbore of 20 mm (0.79 in). Some also claim an increased velocity with the overbored barrels, up to 15 m/s (49 ft/s), which is due to the larger swept volume of the overbored barrel.
The Washington Metro 4 ft 8 + 1 ⁄ 4 in (1,429 mm), the gauge is 1 ⁄ 4 inch (6 mm) less than 4 ft 8 + 1 ⁄ 2 in (1,435 mm) The trams in Nuremberg for one time nominally used 1,432 mm (4 ft 8 + 3 ⁄ 8 in), the gauge is 1 ⁄ 8 inch (3 mm) less than 4 ft 8 + 1 ⁄ 2 in (1,435 mm) The MTR uses 1,432 mm (4 ft 8 + 3 ⁄ 8 in) on most lines.
