Grinding Chain

[10range]

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

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).
