Yeah Ed, I am just a youngster. Even though I am a 5th generation foundryman, I only worked in the business for 35 years, and never picked anything up from my dad, or his dad. You're right though, I did loose you 'long the way'. I didn't need to be there to know how metals were made and heat treated; it's pretty well documented, and, wow, even still discussed. It boils down to your lack of my familiarity with the topic that leads you to think what's common sense. It's very easy for someone skilled in the business to have the exact chemistry analyzed and re-heat treat a part to equal, if not superior physical properties
