Getting back to one of the original questions.

Bronze bushings. I have only used them on non-drive train parts. Especially for arm gear boxes and such. something that will see a Pi or less revolution in a matter of a few seconds. And then return to its starting point.
Its a personnal bias against bushings for high torque/high rev speeds. But they are all over copiers and printers. And these things can put a high load on bearings/bushings.

So there you have it. An unsupported opinion. But I don't see designing around bushings in drive train gear boxes anytime soon

So close we can almost touch it....And on the West coast its up before the Sun to make kick off :-)
