My first bit of advice would be to look up the standard on keys and keyways. Since you are focusted mostly on inch sizes, try ANSI B17.1-1967 & B17.2-1967 which is now available through ASME @ 345 E. 47th St. New York, New York, 10017 or at
The standards, I believe, have been updated though. You could try these from the ANSI webstore (
(
NASM35756-1998 KEY, WOODRUFF, STEEL, ALLOY, WITH KEYWAY AND KEY SLOT DIMENSIONS (SUPERSEDING MS35756E) $14.50
NA0139-1993 KEYWAY AND KEY SLOT DIMENSIONS METRIC $14.50
ISO 3912:1977 Woodruff keys and keyways $26.00
ISO 3117:1977 Tangential keys and keyways $26.00
ISO 2492:1974 Thin taper keys with or without gib head and their corresponding keyways (Dimensions in millimetres) $26.00
ISO 2491:1974 Thin parallel keys and their corresponding keyways (Dimensions in millimetres) $26.00
ISO 2490:1996 Single-start solid (monobloc) gear hobs with tenon drive or axial keyway, 1 to 40 module - Nominal dimensions $26.00
ANSI/AGMA 9002-A86 (R1995) Bores and Keyways for Flexible Couplings (Inch Series) $43.00
Other than that, since I don't own the standard, can only give you what the Machinery's Handbook has to offer, but in a more condensed format.
