Don,I have the Skew Bevel Gear Calc Sheet Kozo Calculations Rev1. Are there others? Also maybe I missed the making a hob part, that sounds interesting for sure!Nice work on that sheet, BTW!
Those books are now crazy expensive, I have all the Live Steam issues(from number 1 courtesy my dad who got it from the start( but another source is Ed Hume who built a class A Climax and used Kozo's methods. Ed is a funny and good writer, plus an excellent craftsman.Here is a link to the book he did on the CLimaxhttps://www.amazon.com/Climax-Class-Steam-Locomotive-Model/dp/1545404895And here is a link to Ed's photostream on the class A climax which has a lot of good pictures of the processhttps://www.flickr.com/photos/edhume3/albums/72157649854075203
