Please forgive the slight digression, but [further to Peter’s post] I must mention this page which illustrates some sage advice:

Hi Jason,

Your result was far higher than I expected. I did think the larger radius of your bearing would make it easier to turn but it does not seem to be the case. The 26 times that you obtained is just over the Square of my value. If there was more data it might be possible to draw a graph and see if any interim sizes could be read off the graph.

However I doubt neither of us has that much time on our hands.

Regards

Gray,
