Try this - ISBN 159180889 Gear Cutting Practice 1937 Colvin and Stanley.
Lindsay Publications Inc reprinted it On hobbing - there is 22 pages.

Other than coming up with a manual for a gear hobber, I doubt if you are
going to find much info on the web. I checked a few texts and other
than a brief mention there is not a lot of info. Try ABE books for used
books on gears or gear making as such below

Yeah, that's one of the sites that shows a *hob-driven* blank.
Actually, I didn't see any sites with independently driven blanks.
Googling "synchronized gear hobbing" wasn't much help (production /
machinery sites mostly). Does anybody have a good link for
synchronized gear hobbing?
