An apparatus is provided for polishing balls that comprises a cradle that is supported for rotation about a first axis. The cradle is shaped to support a spherical object and includes a ball spinner positioned and adapted to spin the spherical object in the cradle about a second axis that is oriented at an angle to the first axis. The apparatus also comprises a first drive operably connected to the cradle for rotating the cradle about the first axis at a first speed of rotation, and a second drive connected to the ball spinner to spin the spherical object about the second axis at a second speed of rotation. Also provided is a method for polishing spherical objects, comprising the steps of: a) providing a cradle apparatus having at least two wheels for supporting and spinning a spherical object; b) providing a first drive and a second drive; c) providing a polishing apparatus having a tape holder and a tape support; d) rotating the wheels in the same direction about a first axis using the first drive; e) rotating the wheels in the same direction about a second axis using a second drive; and f) pressing the tape against the spherical object while the spherical object is spinning.
