I am still somewhat new to grinding my own chains and have a question about grinding one that had an unfortunate encounter with a rock this morning:mad:

Looking at the chain it appears it only contacted the rock on one side of the chain but the top of the teeth on that side have quite a bit of bevel on them. My guess is that I would need to grind .050 plus to get rid of all the damage. My question is, do I need to go ahead and grind all the bevel out of the teeth or can I leave some? The other side looks normal on the top of the teeth and I hate to grind more than needed. Thanks for any advice.

I have ground hundreds of chains. First I clean the chain as clean as possible and further clean with a wire brush where the grinding will take place.
This keeps wheel much cleaner with less frequent wheel cleaning/dressing.
I pick the worst tooth and grind that. The outer "point" of the tooth is where most of the cutting takes place. I take about 10 to 20 thousands off GRADUALLY. Go down a small amount, pause and then go further. This prevents overheating.
I grind all cutters within .010 of each other ON BOTH SIDES checked with a caliper.
 
You do need to grind both left and right cutters to the same length. The teeth that are rocked is where to start by grinding back, a bit at a time, until the damaged area on the outside is no longer visible. If you leave part of the damaged area there it will act like a dull cutter ( which it still is).
