I need some clarification in order to understand the comments about
"pinning" the mast.

What I had mentioned was pinning the two masts (1.00 and 1.50 telescoped
together).  It was as much for having them not untelescope while being
lifted as anything.  An alternative would be to insert shims all around
in the space between the ID of the 1.50 and the OD of the 1.00 (top and
bottom). My thinking is that this would make the thing stronger than if
you just left the slop.  Either way I can't understand how this would
affect the rotator since it is dealing with the OD of the 1.50 mast via
thrust bearings. Please help me with some clarification.  

It sounds like I've been lucky for a long time although it makes a big
difference that my Cushcraft is really only about 8.5 feet above the 4
Element 20.
