Plumb bobs are used in many fields - including surveying, carpentry, construction, and mining - throughout the world. This plumb bob, along with the others in the collection, provide a context for plumb bobs used both in and outside of Canada.

Function

Suspended from an instrument by means of a line, a plumb bob is used to determine the instrument's vertical centre or perpendicularity.

Technical

The plumb bob has remained relatively unchanged since antiquity. Though it can be made out of different materials and its shape may vary, the principle remains the same: a symmetrical weight is suspended from its broad end on a cord or a chain. This plumb bob is made of wood and has a simple, carrot-like shape. It was probably made by a carpenter for use in building construction.
