Also, going by the above quote, I'm not sure how much your hardness tester is going to help you.......
You had me scratching my head on that one John. I'm a huge advocate of hardness testing because it's not uncommon at all to get surprises - whether from misidentified steel, alternate suppliers, environmental fluctuations, prior HT attempts, and so much more.
It finally sunk in what you are talking about. Travis is talking about edge quench and clay coating - and the tester needs a flat parallel surface for anything approaching a meaningful reading. Excellent point!
