On LISA
I thought tension of the leadscrews was important.
Thus tensioning the leadscrew causes Axial load on
top and bottom bearings in the plywood plates.

What is the purpose of tentioning the leadscrew?
Can you really tension a steel leadscrew much with a polymer clamp/nut?

If the leadscrew is tensioned between top and bottom plates
the stepper motor is not seeing any load.

Wouldn't a taper bearing top and bottom do the trick?

:S
