Hi all:
First, I want to thank all who helped out with ideas and information on this project.
To make a long story short I went from laying out and designing the gear using Law’s book on gear design to a final answer that used readily available miter gears. I opted for miter gears rather than bevel gears for a number of reasons. Primarily they required the least amount of effort to implement. The idea for miter gears came from a fellow modeler who pointed out some other approaches to gears.
The project is done and the governor works just fine as you can see in the video link.
I have attached two PDF files due to site size restrictions with all the information I gathered.
The first PDF file starts with a discussion of choices. There is a complete layout for the 22 and 33 teeth gears for those who might want to try that approach. Then there are pictures of the ¼ Scale Minneapolis setup at the Rock River Thresheree.
The second PDF file contains a detailed discussion of the miter gear choice and of how I made the changes and the specific gears I used (lots of pictures). The total time from when the gears arrived to running on the engine was two days, not all of which was in the shop. I think I spent about 12 hours on the project once the approach was chosen.
Thanks again
Bob
