Wheel spokes

Very interesting. I had always assumed that counterweights were centered exactly opposite the pin holding the rods. While that appears true for the front and middle A drivers, it is obvious from the drawing that it is not true for the main driver. Would this be because the added weight of the main rod throws the balance off-center?

Richard,

I'm surprised no one else has answered this yet. The number is 15.

You can see drawings of the drivers at the following addresses:
