I am building an Upshur Farm Engine from the plans presented in the "Strictly IC" now defunct magazine. I decided to build this engine from materials laying around my workshop. Not wanting to spend a fortune on gears I thought about making gears, but after a lot of reading and thinking, I gave it up. In searching the internet, I found a source of inexpensive gears. The model race car guys seem to have every ratio imaginable. I purchased two gears from Amain Hobbies for a total of less than $14 including shipping. The 30 tooth gear is aluminum and the 60 tooth gear is a composite. It was a simple matter to bore the gears and install the cam and bushings (loctite and JB weld). I have attached photos of the finished gears. The mesh perfectly and I anticipate no problems with them. Rick

Those look like a good option, especially at that price! Thanks for the tip!

Thanks for the tip on where to get gears. I'd never thought about hobby model suppliers as a source for gears.
I do have a question though. I looked through the Amain Hobby site and I can see the DP and tooth count specified, but I couldn't find anything about the face width. Is there a way to find that or figure that dimension out?
Thanks!
