Abstract
Using a standard ice auger having a central shaft, a spiral flighting affixed thereon, and an ice cutting blade at the lower end of the flighting, a cylindrical ice hole is bored through an ice sheet. The inventive apparatus, mounted adjacent a lower portion of the standard ice auger, is then used to form an inverted funnel-shaped area at the lower end of the cylindrical ice hole. The inventive apparatus includes a bracket mounted to the ice auger and an ice hole flaring blade pivotally mounted to the bracket. A spring biases the ice hole flaring blade toward a transport position wherein the blade has its free end extending toward an upper end of the ice auger. The ice hole flaring blade is pivotable to an operable position wherein the blade is aligned generally below the ice cutting blade of the auger and has its free end extending downwardly and outwardly from the central shaft of the ice auger. In this operable position, the ice hole flaring blade is aligned to cut an angled cone-shaped face at the bottom edge of the previously formed cylindrical ice hole.
