Ah.....I think you are referring to my "bible" there. To be accurate though,
it's "Machinery's Handbook", now in it's 26th edition. Though the bulk of
recent changes relate to CNC machining, advanced cutting tools, etc., the
formulas published in older editions are valid, unchanged.

If anyone who's got an interest in "things mechanical" hasn't seen one of
these reference works, it's well worth looking for. It's over 2200 pages of
data on materials, methods, mechanisms, properties, threads, gearing,
components, standards, and more. It's "geared" toward engineers and
machinists, but useful for anyone who tinkers.
