I've posted a discussion of the problem I am facing with main mirror cell
design.  I need to eliminate 'slop'.  See:
http://overton.tamu.edu/aset/krajci/scope-design.htm )very bottom of page)
and specifically:
http://overton.tamu.edu/aset/krajci/cell-bearing.htm

I am trying to find ways to use rolling element bearings to solve two
different problems:

1.  Tilting of the pivot/balance member in the main mirror cell.

2.  Movement of the 'lead screw' collimation bolt.

All comments and feedback are welcome!  (Once I get some good ideas
together on how to approach these design problems, I'll add them to the
website.)
