- Pendulum stops swinging after 1 minute (Brand: Seth Thomas)
Its pendulum seems to be triple component one, hinged 1st at the top hook and again at the bob rod connector A slight but distinct wobble is visible at the top 'hinge' and possibly a smaller one at the bottom one Two component pendulums move in such complex ways that predicting them is mathematically impossible, a three component one?
