Sometimes called a starter pin or guide pin, these Router Table Fulcrum Pins function as stable guides when routing curved profiles without a fence. When routing inside curves, for example, it becomes impossible to use a straight fence for stability, so a guide pin is used. Fulcrum pins are most commonly used with bearing guided router bits, so that the bearing and fulcrum pin form two points in a line for stability. More than one pin can be used for more versatility and more complicated profiles. These fulcrum pins are pre-threaded to fit
