Ultra-Light Gages

A large diameter or deep-throated gage no longer has to be heavy and hard to handle. Starrett special gage engineers have studied the physical and structural properties of honeycomb aluminum, establishing standards covering the selection and use of this lightweight material. The results were long-range measurement to close tolerances in hand-held gages of many configurations, all combining great rigidity with light weight and ease of handling. It measures diameters to 72" (180 cm) and throat depths to 24" (60 cm).


Ultra-Light Deep Throat Gage

This deep throat indicating micrometer gage solves the problem of checking the .281" (±.005") thickness of a fan rotor shaft at a point nearly 15" from its edge.


Ultra-Light Large Diameter Gage

This gage is used as an indicating snap gage by setting the indicator to zero with the set master and then reading the part size variations on the indicator. These gages can be supplied with dial or digital indicators.

Sizes are available from 18" to 24" through 84" to 90".

A Starrett No. 234 End Measuring Rod with insulated grips and saddle-centering mounts is the set master.

This gage can be made into an adjustable snap gage by fitting one end with a micrometer and the other end with an indicator. Other concepts are available to suit specific requirements.
