The Jewels of the 3 principal officers of a Lodge are also the working tools of the fellowcraft degree.. They are the: PLUMB, LEVEL, and SQUARE.. Why are these jewels given these distinctions? There are 2 basic reasons: First, in earlier times, the fellowcraft was the ultimate degree.. There was no Master Mason degree. The fellowcraft was the Journeyman of today.. The working tools of a fellowcraft were the tools of a master craftsman or journeyman.. When the master mason degree was instituted, other working tools were selected to fulfill the ritual requirements. Secondly, while masonry makes use of many esteemed working tools, (ie: Gavel, 24" gauge, trowel, skirret, chisel, pencil, setting maul, etc..) it is the square, level and the plumb which are the fundamental tools that are absolutely necessary to erect any edifice be it physical or spiritual..A plumb-bob or a plummet is a weight, usually with a pointed tip on the bottom, that is suspended from a string and used as a vertical reference line, or plumb-line..The instrument has been used since at least the time of ancient Egyptto ensure that constructions are "plumb", or vertical. It is also used in surveying to establish the nadir with respect to gravity of a point in space. They are used with a variety of instruments (including levels, theodolites, and steel tapes) to set the instrument exactly over a fixed survey marker, or to transcribe positions onto the ground for placing a marker..A bob is the weight on the end of a pendulum most commonly, but not Exclusively, found in pendulum clocks...http://www.youtube.com/watch?v=mJRfuxxDxSk

The weight of the bob itself has little effect on the period of the pendulum. However, a heavier bob helps to keep the pendulum moving smoothly until it receives its next push from the clock's escapement mechanism. That increases the pendulum's Q factor, making the motion of the pendulum more independent of the escapement and the errors it introduces, leading to increased accuracy. On the other hand, the heavier the bob is the more energy must be supplied by the clock's power source and more friction and wear occurs in the clock's movement. Pendulum bobs in quality clocks are usually made as heavy as the clock's movement can drive. A common weight for the bob of a one second pendulum, widely used in grandfather clocks and many others, is 15 lbs (6.8 kg)..In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is,or equivalently, characterizes a resonator's bandwidth relative to its center frequency... Tower clocks sometimes have a tray mounted on the pendulum rod, to which small weights can be added or removed, to adjust the rate without stopping the clock..Chalk lines and plumb-bobs are often sold as a single tool..Later, Number 6 is invited to The Green Dome where he and Number 2 watch the woman wake up on the main viewing screen. Number 2 says that she is Number Eight and that she will be Number Six's new neighbour...http://www.youtube.com/watch?v=KuymT671ENE
