I used to have or still have and cant find the book or papers i had on
the terminology for gears: like what do they call the teeth of the
gears and the valleys and the part in between???? is there a web site on
gears that i can look over and see what they are called??? years ago i
went to our public library and there was a book(old trade school text
book) form Henry Ford's school, it covered just about everything
mechanical and metal cutting, i remember copying the stuff and now cant
find the papers that i copied, hope the paper never rotted away,
The library came into some tax money and bought a whole new collection
of books and got rid of alot of old stuff... I wish i was there when
they were throwing it away.........
You may be referring to "Shop Theory" by the Henry Ford Trade School.
