Put the safety gloves on and lay the flighting down on a work bench.
Use a pair of wire snips to snip the aluminum or plastic banding holding the flighting together.
Grasp the left end of the flighting with your left hand and grab the right end of the flighting with your right hand. Twist the right side downward and twist the left side upward and gently pull the two ends apart. This will allow the flighting to expand outward in an accordian-like fashion.
Insert the end of the auger rod through the center of the right side of the flighting.
Twist the rod to the right as it is gently forced through the length of the flighting. Twist the ends of the flighting so that it contracts around the rod, as the rod is worked through.
Snap the left end of the flighting into the narrow slot on the end of the rod. Snap the right end into the right end of the shaft. If these slots are not present on the particular auger rod, place a welders mask on and weld the two ends to the rod.
