A beautiful hand crafted desk accessory or teaching aid illustrating the operation of a Cam and Follower.
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the follower, which is a lever making contact with the cam.
Place one on your desk and reel in the interest as visitors and colleague cannot resist operating the crank handle and such a pleasant change from pen holders and paperweights!
