Standard Gage - Dorsey Metrology
Repairs Long Island Indicator Service is an authorized repair service, fully qualified to perform professional repairs on Standard Gage metric dial bore gages.
Sales Information Standard Gage dial bore gages were manufactured in Poughkeepsie, New York until 2002. They made several different bore gage configurations at that time (perpendicular and vertical for example). Only the regular model (shown below) and the 90° right-angle model are still available (see page 114). Surprisingly, the indicator movement is now supplied by Käfer in Germany. The newest models of Standard Gage dial bore gages are manufactured in Switzerland by Tesa and at least partly assembled in the USA. Tesa is the manufacturer of high-end Etalon, Compac and Interapid gages. As an alternative, you may wish to purchase the Standard-style bore gage made in USA. These have identical measuring heads but the dial indicator will carry the name Dorsey.
In order to keep prices down, most of these gages ship in a simple styrofoam box. However, sturdy wood storage boxes are available for special orders such as bore gages with long depth extensions and for the combi-kits. Wood boxes can also be purchased as an option (see page 72).
Bore Gage Size 3 (inch reading) is shown above. Metric models will have yellow dials. The Centralizing Plungers automatically locate the gaging contacts on the bore diameter even when the gage is inserted at an angle. Standard Gage dial indicator has 0.002 mm graduations and each model comes with all range extensions and adapters. The indicator has a yellow 0-10-0 dial—making 4 revolutions—for a total of 0.8 mm travel. The gaging depth shown is the maximum depth without extensions (available separately). Setting rings are not included. Models with the DS- prefix (below) are made in USA by Dorsey of Poughkeepsie. They are identical in every way except for the dial indicator which will have the Dorsey name on it. Buying these will save you money and you'll be supporting an American manufacturer. We wouldn't sell them if we didn't think they were worth-while. | ||

Bore gage depth can be specified when the gage is purchased. Alternate depth extensions are available for bore gage model 2, 3, 4, 5 and 6. The depth which these bore gages can reach is called the "A" length and this length is available from 64 mm to 1,8 meters in various intervals. Please inquire about pricing and delivery. Extensions are not available for model 0 and model 1. Extensions can also be purchased at a later time. Although, bought separately, they cost twice as much. The extension replaces the entire middle portion of the bore gage. You will have to insert it between the dial indicator and the measuring head. For example: a 250 mm extension, although only 230 mm long will give you a usable measuring depth of 250 mm when installed. Installation is self evident and not complicated. If you wish to purchase separate extensions, refer to the parts list.
Contact Points (plungers) Each bore gage comes with a steel gaging plunger and steel centralizing plungers as shown below. Other combinations of carbide and diamond are also available.
