This is the result of a major brain fart on my end. For the life of me, I
can't figure out where my mind was when I sent the original post. Looking at
the plans, it is obvious to all (but me) that the control torque tube DOESN'T
bend or scribe an arc. OOPS!
The bearings may still have some value as a way the eliminate the possibility
of binding due to bearing bracket mis-alignment when building. Think of them
as working in the same way as a rod end bearing would work of the control
torque tube was passed through the center. Able to take a wide range of mis-
