Chops, located on the ends of a pendulum's suspension spring, are designed to get a more solid grip on the spring. With a degree of helpfulness varying from outstanding to useless, chops give a constant fixed length to the suspension spring and prevent the suspension spring from rocking back and forth on the top edge of the crosspin through the top end of the suspension spring. This chapter discusses the rocking of the suspension spring on one of its crosspins. A typical suspension spring has its ends pinned in narrow slots and contains no chops, with the slots slightly wider than the thickness of the spring. As the pendulum swings back and forth, the spring's ends bend or wiggle back and forth a little in the slots. The wiggling is more pronounced in the top slot than in the bottom slot. There would be no rocking motion if the spring's ends were a tight fit in the slots.
