Form or profile gauges
Form gauges or profile
gauges:
A
profile gauge or contour gauge is a tool for recording the cross-sectional
shape of a surface. Contour gauges consist of a set of steel or plastic pins
that are set tightly against one another in a frame which keeps them in the
same plane and parallel while allowing them to move independently,
perpendicularly to the frame. When pressed against an object, the pins conform
to the object. The gauge can then be used to draw the profile or to copy it on
to another surface.
