You know, I just bet that GE wouldn't take court action about your
copying a book
that has been obsolete for 30 years! I've been thinking about modifying
some of
the material in an Allen-Bradley manual from about the same vintage for
my web page
on CNC programming. The drawings are fine, and the programs only need
to be
updated for the same reasons you mentioned, decimal points and arc
quadrants.
They also have real good info on cutter radius comp. and tool length
offset.
