I just got off the phone with Bourn & Koch Gear they are familiar with the book but do not have any. They do offer a computer program either in DOS or Windows format called Four Gear Ratio. It will calculate a given ratio and allow you to select the tolorence. It calculates gears between 20 and 100 teeth. The Windows version allows you to input gears you don't have so it won't use them. It sells for &100.
