Grinding deer meat this weekend with the grinder attachment on my wife's Kitchenaid and it stopped working. Crap. Now, I know what the problem is because I looked it up. All it is is a nylon worm gear that is DESIGNED to fail when the mixer has worked too hard so that it saves the rest of the motor. It's a 1 hour fix with a $5 part. That was beside the point. The fact that I didn't take care with one of her most prized posessions was the main issue. I appologized and promised to fix it within the week. Best I could do. I'm still in the doghouse though.
