1. An ice hole reaming assembly in combination with an ice auger having a central shaft with an upper end and a lower end, a helical blade affixed along an inside edge to the central shaft and extending outwardly therefrom, a concave split ring affixed about the lower end of the central shaft, an ice cutting blade reversibly attached to a leading edge of the split ring, and a vertically oriented ice penetrating blade affixed to the lower end of the central shaft, said ice hole reaming assembly comprising:
a series of cutouts along the inside edge of the helical blade, said cutouts in vertical alignment forming a channel adjacent to the central shaft; a cylindrical receptacle having an upper rim and a floor securely affixed to the central shaft beneath the channel near the lower end of the central shaft; a rod disposed within said channel and extending substantially the length of the central shaft, said rod having a first end and a second end, said second end being disposed in the receptacle such that the rod is supported therein, said rod being parallel to and in spaced relation with the central shaft, a portion of the first end of the rod extending above the channel being bent into a right angle said bent portion forming a handle; an ice reaming blade having a top edge, a bottom edge, front and back surfaces, a rear edge and a forward angled cutting edge, said ice reaming blade being securely attached to the rod above the upper rim of the receptacle, said attachment to the rod being along the back surface adjacent to the rear edge, said ice reaming blade extending outwardly from the rod so as to be positioned directly beneath and in the same plane as the handle, and said ice reaming blade having a rest position wherein it does not extend beyond the split ring and a use position wherein the ice reaming blade extends outwardly beyond the split ring to ream the ice hole; a retaining loop affixed to the central shaft above the top edge of the ice reaming blade and encircling said rod, the rod being freely rotatable within the retaining loop, said retaining loop to maintain the rod in vertical orientation adjacent to the central shaft and to prevent the rod from being lifted out of the receptacle; and a latch assembly affixed to the central shaft substantially at the level of the handle and positioned such that when the handle is engaged in the latch assembly the ice reaming blade is in the rest position and when the handle is released from latch assembly the rod rotates and the ice reaming blade is moved to the use position; whereby the ice hole can be drilled and reamed in one operation while the auger is activated. |
