Hey Herb, I tried your quick fix with JB Weld and a file and it worked well. I ended up patching 2 of the teeth. There was a little slag on the bottom of one that scraped right off. For filing them down I used a 80 grit piece of sand paper. I would sand then try to run the guide bushing through the slot. The JB Weld sanded down very easily and when all was done just a little bit was left on the teeth when the guide bushing ran through the slot. The guide bushing ran smoothly so hopefully that will improve the cuts.Marco, for a quick fix until you can replace it, can you get some JB Weld and build up that gouge and file it smooth?
