What is a jenny caliper?
|Jenny calipers are sometimes called odd leg calipers, oddleg jennys or hermaphrodite calipers.
|A jenny caliper works in a similar way to a compass. One end is set in a fixed location, and the other is used to scribe or measure.
They are used to draw a line a set distance from the edge of a part but are also useful for locating the centre of a workpiece.
Jenny calipers are primarily used with parts made of metals such as steel, but can also be used with glass and hard plastics.
|Oddleg calipers are a cross between a divider and an outside caliper, as they have one leg of each of these tools.

|Jenny calipers have either a spring joint or a firm joint. Some also have an adjustable point which increases the capacity of the tool.
