A dial bore gauge is a comparative instrument similar to a telescoping gauge, but includes a digital or analog readout. The dial bore gauge must be set to the nominal value of the bore, and it will measure the variation and direction of the bore from nominal. There are multiple ways to set this gauges to the nominal value.
The 20-gauge shotgun is the next most popular size [citation needed], and is popular for upland game hunting. The next most popular sizes are the .410 bore and the 28 gauge. The least popular sizes are the 10 gauge and the 16 gauge; while far less common than the other four gauges, they are still commercially available. [citation needed] [9]
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.
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.
The difference between a 1 and 2 gauge bore, however, is 25%. This is a significant amount, so it makes sense to have a division in between. This source lists loading data for punt guns of 1 to 1 1/4 inch (4 5/8 to 2 3/8 gauge), 1 3/8 to 1 1/2 inch (1 3/4 to 1 3/8 gauge), and 1 5/8 to 1 3/4 inch bore (1 gauge to 1 1/8 pounder). If there were no ...
Gauge block, a metal or ceramic block of precisely known dimension, used in measuring; Sight glass, also known as a water gauge, for measuring liquid level heights in storage tanks and pressure vessels; Boost gauge, a gauge used in conjunction with turbo-super-chargers; Pressure gauge or vacuum gauge, see pressure measurement
Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.
Oppose: Several common uses do not fit this definition – e.g., Gauge (bore diameter), Wire gauge, and Track gauge, just to name a few. Often, the term "gauge" seems to refer to the size of something rather than a measurement instrument. There are a lot of different uses, so perhaps the dab page should remain at the base name.
