[python] Re: car wheel bearings pivot

Thank you; that's really helpful.
These designs don't allow for the adjustment of the axial loading that I was 
looking for, except that the worm design seems to implement some shims.
But the fact that these work tells me that maybe I don't need that adjustment.
I think I'll just tighten the assembly to the torque recommended for car 
wheels, and build the coupling to the rest of the frame to fit the dimension 
that results.
Thanks again.

I haven't forgotten to provide you with photos and measurements of my python. 
I'm still adjusting; for instance, I shortened the wheel base last weekend, and 
I'm happy with the result. I'll apply some paint, make the measurements, 
photograph it and send all that to you soon.
