What happens here

A router circle jig is demonstrated for accurately cutting perfect circles from a sheet of wood. The jig typically consists of a long arm or base plate attached to the router, with a pivot point (a screw or pin) fixed at the desired center of the circle on the workpiece. The router, with a suitable bit installed, is then guided along the jig's arm in a controlled circular path, making repeated shallow passes to create a clean, precise circular cut in the wood.

Goal: Cut perfect circles from wood using a router.
