This is the finished pier column.  I had the red "wedge plate" custom made which allows the wedge to be permanently attached to the pier bolts.  It is adjustable east west to allow for accurate polar alignment.  Once drift aligned, it need not be readjusted (unless there is an earthquake).  The fork assembly and OTA are taken down after each session.  The LeSeur Astropier will utilize the same bolts.  The floor can now be built around the column, independent of it.  By not touching the column, the floor will not induce vibrations from walking, dropping counterweights, etc.
