RE: Pride Goeth Before a Fall



David and all,

Lots of reasons to ask for suggestions and help.  This note reminded me of
the other solution.  Use a soft screw and a hard block.  Nylon screws are
readily available.  Sigh!  That is the one screw I did not order from the
catalog today.  But I thought briefly about it.   For our exposure times,
the periodic error is more serious than possible errors from stretching or
moisture absorbtion of the Nylon.
