Is that process indexing? I noticed it was grinding mostly one side. I didn't think about how the crankshafts can be "off" in the index department until you mentioned it maybe in another post.
I saw that as well. I can only assume one of two things. Either he was straightening up an egg shaped journal, or perhaps he was offset grinding. I'm assuming the first since offset grinding would have been removing more material. Rest assured, if @MOPAROFFICIAL uses him, he knows what's up.
