That is the way I saw it. And to answer the hardness through and through, look at it this way. The only reason to have them hard at all is to provide the needed difference in hardness between the cam and shim. If we grind the "down" side, it rests against the bucket, so there is no care if it is hard or not, since there is no movement between them. You will still have the hrdened surface against the cam. I have the grinder, but no way to test hardness. If you had a tester, and we could find a patron, we could find out. CZ
