![]() The head is attached to the central sun gear. The head of a Perfection peg is made either of ebony, rosewood, or ABS synthetic (the plastic often used in car bumpers). They have the same shape, weight and taper as a set of good ebony pegs. Perfection pegs have a standard taper and fit in the same holes as standard wooden friction pegs. Conversely, if the peg becomes difficult to turn, gently pull the peg head away from the peg box as you turn and you will feel the action become easier. If at some stage you find that the string is not holding, gently apply more inward pressure as you turn and this will firm the action. In practice, you find a setting that works for you and tend to leave it at that point. ![]() As you try this you quickly discover how to adjust the peg for ease of turning and optimal hold. Do the same thing while gently pulling outwards on the head. To get a feel for how the pegs work: for each peg, back the peg off a couple of turns to release the string tension and several times work the head backwards and forwards a half turn each way as you applay a gentle inward pressure to the head. The reverse happens when the peg head is gently pulled outward as it is turned: the action of the peg is released, becomes softer and the string is able to unwind. Like applying the brakes of a car or a bicycle: as you press the brakes you gradually slow down, come to a stop and then are locked in position by the brakes. When tuning: pressing the head of a Perfection peg inwards as you turn it stiffens the action in a gradual and crontrollable way, and this allows the peg to hold the string at tension. The 4:1 gear reduction gives the Perfection peg the precision to act as its own finetuner. The shaft turns once for every four turns of the head. The motion of the planet gears rotates the shaft, which then takes up the string. As the sun gear turns the planet gears orbit around it. Three planet gears are held between the sun gear and an outer ring gear. Turning the head of a Perfection peg rotates its main central sun gear. Knilling's Perfection Planetary Geared Peg is an innovative tuning peg providing a fine tune and “non-slip” solution for your violin, viola or cello. The 4:1 gear reduction gives the Perfection peg the precision to act as its own finetuner. ![]()
