Ugh - I don't care for pier pins because of the time and effort needed to
secure the temporary guys.
I'm doing a job right now with the same circumstances (tree fell on guys and
pulled the top of the tower down) and what we're going to do is to drill the
concrete base and epoxy in 3 or more anchor rods, put a nut on each rod (your
hardware store allthread is plenty) and then use a flat mounting plate (drilled
appropriately to mate with the anchor rods). Use the bottom nuts to plumb the
first section and then secure with top nuts. Voila - quick and easy and no
welding.
