I Picked up a 8" Bass Pro Brand Auger a few seasons ago and its been good to me. just sharpened the blades at the start of the season and didn't put any locktite on the bolts...well now one of my blades is at the bottom of long lake, and the bass pro hotline number says they don't sell replacement blades. Does anyone have one of these and found replacement blades? am i SOL? Will another blade work? any info would be appreciated. I don't want to buy a new auger because I've already welded a homemade drill adapter to this one.
