Cam

How it works

• It is a gear with an egg-shaped bump on its rim.
• Each turn, the bump lifts whatever rests on the rim and lets it drop.
• Nothing balances on the rim. A ball set on top rolls straight off, so give it a follower, such as a seesaw resting on it or a crate in a chute over it.
• It meshes like a normal gear and stays where it is set until something turns it.

Tips

• A crate in a chute needs a little room on each side, or it wedges.
• Build mode shows how far the bump reaches.
