I currently have a listing on ebay for the Model 18 and Model 19 replacement gear. I have had a few requests come in for the Model 17 and will make some available soon.

My assumption has been that if you even know your gear is broken, then you know how to open the sharpener and remove/replace a gear. Even if you are not a Jedi Do It Yourselfer, this is not a tough repair. A photo-guide for this is the next project...
