useful charts or calculators for working metals and other materials

[Toolmaker51]

May I suggest;
Jon, initiate a distinct category in the HMT forum of tables [or links to] such as Frank S, Doug Ross, Marv Klotz, Rick Sparber, PJs and others compiled. I'm not playing favorites, they're in no particular order.
Marv's though are of his own composition, so we can alleviate tedious calculations.
