I measured a tilt of less than 10 microns over a 60mm diameter and I think it would be unrealistic to expect anything better.
Next I will test backlash and lift capacity.
Rigidity is determined by the thickness of the two sleeves and the spacing of the bearings. To make it any stiffer, I would have to make it longer or to make it out of titanium.
The clear aperture is 50.
