Cut any gear with just a slitting saw

This is about the simplest way to make an accurate gear with the minimum of equipment, just a milling machine and a rotary table, no special attachments, no hobs or special cutters. And best of all you can use this method for any gear, even obscure sizes you can't get cutters for.
