Abstract
A removable bowling ball thumb insert sleeve for installation in a bowling ball hole, having an expander within a short counterbore in the bottom portion of the thumb insert sleeve. The expander device is actuated by rotation of an actuating screw using a tool inserted through a center bore within the thumb insert sleeve. Actuation of the expander device expands a split ring within the counterbore to engage the sleeve and urge it radially outwardly to engage the wall of the bowling ball hole and frictionally retain the sleeve within the hole.
